How to find out what electricity tariff you’re on

There are three quick ways to check, in order of how fast they are:

1. Your online account or app. The fastest method. Log in to your supplier’s website or app and look for “My tariff”, “Your plan” or “Tariff details”. It will show your tariff name (for example “Flexible Octopus”, “Next Flex” or “Standard Variable”), your unit rate in pence per kWh, and your daily standing charge.

2. Your latest bill or annual statement. Your tariff name is usually printed near the top of your bill or on the “tariff information” section. Suppliers are required to show your tariff name, unit rate and standing charge clearly, so it’s there even if it’s not on the front page.

3. Ask your supplier. If you can’t find it, your supplier’s customer service or live chat can tell you in minutes. You’ll need your account number, which is on any bill.

If you’ve never actively chosen or switched your tariff, there’s a very good chance you’re on a standard variable rate (SVR) — the default rate your supplier puts you on when a fixed deal ends or when you move in somewhere new. That matters, because the standard variable rate is rarely ever the cheapest option available.

What the different electricity tariff types mean

Knowing the name is only half the picture — what matters is the type, because that determines how you’re charged:

• Standard variable rate (SVR): This is sometimes also referred to as the Standard variable tariff (SVT) and is the default. One unit rate all day, which can change when the price cap changes. Most UK households are on one of these.
• Fixed tariff: your unit rate and standing charge are locked for a set term (usually 12 months). Offers price certainty, but isn’t automatically cheaper.
• Economy 7 / Economy 10: an older two-rate setup with a cheaper overnight rate, designed for storage heaters. Still common in electrically-heated homes.
• Time-of-use (smart) tariffs: newer tariffs with cheaper rates during specific windows — overnight for EV charging, or off-peak windows for heat pumps and electric heating. These can save a lot if you can shift usage into the cheap periods.

The more important question: are you on the right electricity tariff?

Finding out what you’re on is easy. The question that actually saves you money is whether it suits how your home uses electricity — and this is where most people lose out without realising.

A standard variable tariff treats every unit the same, whatever time you use it. But if your home has an EV, a heat pump, electric heating or a home battery, you use electricity in a very different pattern from a gas-heated home — and a tariff built around that pattern can cut your bill substantially. An EV charging overnight, for example, can run on a rate a third or less of the standard daytime price. A heat pump can shift much of its work into cheaper windows.

The catch is that working out which tariff is actually cheapest for you isn’t simple. It depends on how much electricity you use, when you use it, what equipment you have, and which region you’re in. Headline rates don’t tell you — a tariff with a low advertised rate can work out more expensive once your real usage pattern is taken into account.

Check if you’re on the right tariff

Rather than guess, you can model it. Our free Smart Tariff Calculator compares over 50 UK tariffs — including 38 time-of-use options — against your actual electricity usage, equipment and habits, and shows you what you could save by switching, with the assumptions behind every figure. There’s no sign-up needed to see your results.

It’s particularly useful if you have an EV, a heat pump, or electric heating, where the right time-of-use tariff makes the biggest difference — but it works for any home.

Frequently asked questions

Where do I find my tariff name? On your latest bill (usually near the top or in the tariff information section) or by logging into your supplier’s online account or app. If you can’t find it, your supplier’s customer service can tell you with your account number to hand.

What tariff am I on if I’ve never switched? You’re most likely on a standard variable tariff — the default rate your supplier applies when a fixed deal ends or when you move into a property. It’s rarely the cheapest option, especially if you have an EV, heat pump or electric heating.

How do I know if my tariff is a good deal? Compare it against tariffs suited to how your home uses electricity, not just on headline rates. A calculator that models your actual usage, equipment and region will show whether a different tariff — particularly a time-of-use one — would cost you less.

Is a standard variable tariff bad? Not necessarily, but it charges the same rate whatever time you use electricity, so it doesn’t reward shifting usage into cheaper periods. Homes with EVs, heat pumps or electric heating usually do better on a time-of-use tariff.

Can I change my tariff whenever I want? Generally yes. If you’re on a standard variable tariff there’s usually no exit fee, so you can switch at any time. Fixed tariffs may have an exit fee if you leave before the term ends — check before switching.

Smart Tariff Calculator UK

The number of smart electricity tariffs available in the UK has expanded rapidly over the last couple of years. What was once a relatively simple market has become increasingly complicated, particularly for households with an electric vehicle, heat pump or electric heating.

There are now dedicated EV tariffs with cheap overnight electricity, heat pump tariffs designed around heating demand, dynamic tariffs like Agile where prices change every half hour, and a growing range of time-of-use tariffs designed to encourage households to shift electricity usage away from peak demand periods.

For many homeowners, these tariffs can reduce electricity bills significantly. But identifying the right tariff is becoming much harder.

Most comparison websites still rely on generic “average household” assumptions which often fail to reflect how modern electric homes actually use electricity. A household charging an EV overnight behaves very differently from a gas-heated home with low evening demand. The same is true for homes running heat pumps or electric heating systems.

That is exactly why we built the Smart Tariff Calculator

Why most tariff comparison tools struggle

Traditional tariff comparison tools were designed for a much simpler energy market. They generally work reasonably well for homes with predictable electricity usage and gas central heating, but they become far less accurate once large electrical loads are introduced.

Electric vehicles, heat pumps and electric heating systems all change not just how much electricity a household uses, but when it uses it. That distinction matters because smart tariffs are heavily dependent on timing.

A household that can shift large amounts of electricity consumption into cheap overnight periods may benefit enormously from one tariff, while another household with similar annual consumption but different behaviour could end up paying more.

This is one of the major limitations of many mainstream comparison sites. They often compare tariffs using estimated annual usage totals without properly modelling the timing of electricity demand.

A smart tariff calculator based on your actual usage

The Smart Home Energy Tariff Checker takes a more detailed approach.

Instead of relying entirely on estimates, it can work from your actual smart meter data if you are with Octopus Energy, helping build a much more realistic picture of how your household consumes electricity throughout the day and across the year.

If you are not an Octopus customer, the tool can also estimate your annual electricity consumption from uploaded bills, or work directly from your known annual usage figures if you already have them available.

The aim is to move away from generic assumptions and towards modelling how your own home actually behaves to gain more accurate savings estimates.

Designed specifically for EVs, heat pumps and electric heating

One of the biggest differences with the calculator is that it does not simply ask for your annual electricity consumption and stop there. Different technologies create very different electricity demand patterns, so the calculator asks additional questions depending on your setup.

For EV owners, it’s really hard to compare Intelligent Octopus Go vs E.ON Next Drive directly without a lot more details and some pretty complicated math. So our EV tariff calculator considers your cars’ efficiency, annual mileage, charger type and charging behaviour. Since EV charging can often be shifted into cheap-rate periods, understanding how and when you charge can make a major difference to tariff recommendations.

For heat pump households, the calculator attempts to account for heating demand and how electricity usage changes seasonally, especially during winter when consumption often rises sharply.

Homes with electric heating systems also behave very differently depending on the type of heating installed and how it is used. Storage heaters, direct electric heating and underfloor systems all create different usage profiles which can dramatically affect which tariff works best.

Comparing tariffs properly — including Agile

One of the hardest tariffs to compare accurately is Octopus Energy Agile. Because Agile prices change every half hour, simply looking at average rates tells you very little about what your actual annual bill might be.

The calculator therefore maps an entire year of half-hourly Agile pricing data against your actual usage (or estimated usage profile depending on your inputs) in order to model exact potential savings.

This matters because some households can benefit significantly from Agile pricing while others may find more predictable fixed time-of-use tariffs work better for their usage patterns. Without modelling actual behaviour, it is very difficult to compare these tariffs meaningfully.

Confidence scores and editable assumptions

Another problem with many comparison tools is that they present their results as though they are perfectly precise, even though all tariff modelling involves assumptions. Our Smart Tariff Calculator includes a confidence score alongside the results and explains the assumptions used to generate the recommendations.

It also allows you to edit the inputs directly from the results page so you can refine the calculations further.

For example, you may decide to adjust annual mileage, charging times, heating behaviour or electricity usage estimates. As the inputs become more accurate, the recommendations become more tailored to your real-world situation.

Why smart tariff comparison matters more than ever

Time-of-use tariffs have become far more common over the last 18 months and the number of specialist tariffs aimed at EVs and electric heating continues to grow. That is good news for households willing to shift electricity demand into cheaper periods, but it also means choosing the wrong tariff can now be more expensive than before.

A tariff that appears cheap based on headline rates may not actually suit your household at all once real usage patterns are taken into account. For homes with EVs, heat pumps or electric heating, proper tariff comparison is becoming increasingly important.

Solar and battery support – now live

We recently added support for solar PV or home battery systems.

The calculations become significantly more complicated, but we think we have accounted for most aspects (although modelling self-consumption needs more details).

If you own an electric vehicle and you’re still on a standard electricity tariff, there’s a good chance you’re paying more than you need to for charging.

Over the last couple of years, energy suppliers have launched a wave of specialist EV tariffs with cheaper overnight electricity rates designed around when electric cars are usually plugged in. Two of the best-known are:

• Octopus Energy’s Intelligent Octopus Go
• E.ON Next’s Next Drive

At first glance they can look quite similar: both offer cheaper electricity overnight so you can charge your EV for less. But once you look more closely, the differences become more important — especially if you charge frequently, work from home, have solar panels, a battery, or eventually plan to add a heat pump.

The problem is that most comparison websites still compare tariffs using “average household” electricity usage profiles, which often bear little resemblance to how EV households actually use power.

That means the “cheapest” tariff on a comparison site may not actually be the cheapest for you.

Why EV tariffs can save so much money

Traditional electricity tariffs charge the same unit rate all day. Time-of-use (ToU) tariffs work differently. Electricity becomes cheaper at certain times — usually overnight when national demand is lower.

For EV drivers, that matters because charging an electric car can easily become one of the biggest electricity uses in the home. If you can move most of that charging into cheap-rate periods, the savings can be substantial.

Depending on mileage and charging habits, some EV owners save hundreds of pounds per year simply by switching to an EV tariff and charging overnight.

How Intelligent Octopus Go works

Octopus Energy’s Intelligent Octopus Go is one of the most advanced EV tariffs currently available in the UK.

Like a standard EV tariff, it offers a cheap overnight charging window. But the “Intelligent” part comes from the fact that Octopus can directly control compatible EVs or chargers and automatically schedule charging when electricity is cheapest.

Instead of simply giving you a fixed cheap period overnight, the system can intelligently spread charging around lower-demand periods.

In practice, this means:

• Your car can automatically charge at the cheapest times
• Charging is optimised without needing manual scheduling
• Some households can benefit from additional low-cost charging slots outside the standard overnight window

For many EV owners, the convenience is a major selling point. You plug in the car and let the system handle the rest. However, compatibility matters. Intelligent Octopus Go only works with supported vehicles and chargers.

Octopus claim the following savings are available on the Intelligent Octopus Go tariff, compared to their standard fixed tariff:

How E.ON Next Drive works

E.ON Next’s Next Drive tariff takes a more traditional approach. You get a fixed cheap overnight charging window each night, during which electricity costs less. The structure is simpler and easier to understand:

• Cheap electricity is available during set overnight hours
• You manually schedule your car or charger to use those hours
• No intelligent smart charging integration is required

For many households, this simplicity is actually attractive. You don’t need to worry about compatibility with a particular charger or vehicle ecosystem. If your EV or charger can schedule charging overnight, you can usually make use of the tariff.

Intelligent charging vs fixed charging windows – Intelligent Octopus Go vs E.ON Next Drive

One of the biggest differences between Intelligent Octopus Go vs E.ON Next Drive is flexibility.

Intelligent Octopus Go

The tariff is designed around smart optimisation and its advantages include:

• Automated charging schedules
• Potential access to additional low-cost charging periods
• Less manual management
• Better integration with smart energy systems

Possible downsides:

• Vehicle/charger compatibility requirements
• More complex setup
• Less predictable charging windows

E.ON Next Drive

The tariff focuses on simplicity and predictability. and its advantages include:

• Fixed cheap-rate periods
• Easier to understand
• Works with most scheduled EV charging setups
• No advanced integrations needed

Possible downsides:

• Less flexibility
• Fewer opportunities to optimise around changing electricity demand
• May not suit households wanting advanced smart energy automation

Intelligent Octopus Go vs E.ON Next Drive – Which tariff is actually cheaper?

This is where things get complicated. There is no universal answer when you compare Intelligent Octopus Go vs E.ON Next Drive generically. Octopus’ overnight cheap rate is currently 8p/kWh and E.ON’s is 9p/kWh but the cheapest tariff for you also depends on:

• How many miles you drive
• When you charge
• Whether you work from home
• Your daytime electricity usage
• Whether you have solar panels
• Whether you have a home battery
• Your regional electricity pricing
• Your EV charging efficiency
• How much electricity you can shift overnight

This is where most comparison websites struggle. Many major comparison sites still estimate energy usage using broad “average household” assumptions. But EV households are rarely average. A household driving 15,000 miles per year and charging overnight behaves very differently from a non-EV household.

A better way to compare EV tariffs

At Smart Home Energy, we built an EV tariff comparison tool specifically because standard comparison methods often don’t work well for EV households. Our EV Time-of-Use Tariff Checker uses your actual smart meter data (for Octopus customers), real bills, or your exact kWh usage. It collects details about your car type and annual mileage so it can model your usage against all the smart tariffs currently available, including EV tariffs and dynamic tariffs like Agile to show you whether you’d actually save money — or potentially pay more by switching.

Instead of using generic “average household” assumptions, it looks at how you use electricity. That gives a much more realistic comparison for EV owners.

Should you switch to an EV tariff?

If you own an EV and regularly charge at home, it is definitely worth checking. Even households already on an EV tariff are sometimes surprised to find another tariff would work better for their actual usage pattern.

And many EV owners still have no idea how much difference time-of-use pricing can make. The key point is that the best tariff is highly personal. What works brilliantly for one EV household may be poor value for another.

• 1–2 solar panels (usually up to ~800W)
• A microinverter
• A cable that plugs into a regular socket in your home

Once connected, the system feeds electricity straight into your home, reducing how much you draw from the grid during the day.

How does plug in solar work?

Plug in solar works by generating electricity from sunlight in DC and converts it into usable AC power via a microinverter. That power is then used instantly by appliances in your home, thereby reducing your electricity bill automatically. There’s no need for complex rewiring — your home simply uses the solar energy first before pulling from the grid.

Is plug in solar legal in the UK?

As of April 2026, plug in kits are not yet fully permitted under existing UK wiring rules, but that is about to change. The UK government has confirmed plans to enable plug-in systems by updating regulations. Specifically:

• The government is working with the Energy Networks Association, DNOs and Ofgem to update the G98 distribution code and wiring regulations BS 7671
• This will allow UK households to connect <800W plug-in solar panels directly to domestic mains sockets
• Systems will not require an electrician
• New tailored safety standards will be introduced

In addition:

• BS 7671 Amendment 4 (2026) to the 18th Edition Wiring Regulations is scheduled for publication on 15 April 2026
• Often referred to as the “Orange Book,” it includes updates on:
  • battery storage
  • ICT earthing
  • Power over Ethernet (PoE)
• There will be a six-month transition period, with the previous version withdrawn on 15 October 2026

In practical terms, this means plug in systems should become widely available in the UK during 2026 with broader adoption following shortly after. Fill in the form below to be kept updated.

How much can plug in solar save you?

A typical plug in system of 800W should save a typical household around £80–£150 per year on electricity bills, depending on usage patterns, energy prices and how well the panels are oriented towards the sun. Because the systems will be relatively low-cost, if you’re paying £0.26/kWh, systems could pay back in 5-8 years making plug in solar very attractive to suitable homes in the UK.

Will you need an electrician?

No. When the regulations are updated (see below) an electrician will not be required for compliant plug-in systems under 800W. Systems will be designed for safe, DIY installation

Is plug in solar worth it in the UK?

For many households — especially renters or those without suitable roofs — plug in solar offers a low-cost entry into solar energy, a non-permanent installation (so you can take it with you if you move home), immediate bill savings – and a payback period of 5-8 years. Panels will continue to generate energy for at least 20 years providing significant savings over their lifetime.

Under Renters’ Rights Act 2025, tenants can request energy improvements and landlords cannot refuse unreasonably, so plug in solar should be suitable for people that live in rented properties. As regulations update and awareness grows, plug in solar is expected to become one of the simplest and fastest-growing ways to adopt solar energy in the UK because of the attractive savings.

When will the plug in kits be available in the UK?

With regulatory updates landing in April 2026 and transitioning through October 2026, plug in solar is expected to be available in mid or late 2026. Fill in the form below to be kept updated.

What is the best orientation for the solar panels?

Orientation has a big impact on how much electricity your plug in solar system generates.

• South-facing is ideal in the UK for maximum output
• East or west-facing can still work well, especially if your usage is morning or evening-heavy
• North-facing is generally not recommended

For balcony setups, perfect positioning isn’t always possible — but even suboptimal angles can still deliver meaningful savings. A slight tilt (around 20–40°) and avoiding shade are often more important than exact direction.

What fixtures and fittings do you need for plug in solar kits?

Most plug in kits will come with the core components, but mounting and setup hardware can vary depending on where you install them. Typical kits will include solar panels, a microinverter and a plug-in cable. Additional fixtures you may need:

• Balcony rail mounts
• Wall brackets
• Ground frames (for gardens or patios)

The key is stability and safety — panels must be securely fixed and able to withstand wind, especially in exposed locations like balconies.

Can you combine plug in solar with batteries?

Yes — and this is where things get more interesting. A battery allows you to store excess daytime energy and use it later in the evening or at night, which can increase your overall savings. However, basic plug in systems do not include batteries by default and adding storage increases cost significantly

There are now emerging “plug-and-play” battery systems that integrate directly with solar kits and energy monitors, making this much simpler than traditional solar + storage setups. For many users, starting without a battery and adding one later is the most cost-effective approach.

Plug in solar represents a major shift in how people access solar energy — moving from complex installations to simple, affordable systems that almost anyone can use. As UK regulations catch up with Europe, it’s likely to become a mainstream home energy solution in the very near future.

The Cost of Inaction

According to research commissioned by the Retail Energy Code Company (RECCo), energy theft is costing UK consumers an estimated £457 million to £760 million per year. That equates to as much as £28 added to every household’s energy bill — every single year.

But the cost isn’t just financial. It’s human.

“Meter tampering leads to one death every 10 days in Great Britain,”
— Ofgem, June 2025 decision letter

The risks include electrocution, house fires, gas explosions, and severe burns — consequences not only for those committing the crime, but also for innocent neighbours, tenants, and emergency responders.

Energy Theft – The Crisis That Was Allowed to Fester

Despite being aware of these dangers, Ofgem left it to energy suppliers to investigate and prevent theft — a strategy that clearly failed. In Ofgem’s own words:

“Suppliers find it difficult to engage and secure police support… and the cost of investigating more complex instances of theft is a disincentive.”

In the vacuum left by weak enforcement, criminal enterprises flourished. Organised groups began offering meter tampering as a service, enabling cannabis farms, cryptocurrency mining, and other illicit operations. Tutorials on how to steal energy without getting caught are widely available on social media — a direct result of the lack of deterrence.

“There is little fear of prosecution.”
— Ofgem

Perpetrators often escape detection simply by switching energy suppliers. Ofgem concedes that “once the consumer switches supplier, the investigation of the theft stops” — a loophole that has effectively protected repeat offenders for years.

Enter the Energy Theft Unit

The newly established ETU, operated by the City of London Police, will finally bring coordinated enforcement to the table. The unit will be staffed with specialist officers and data analysts and is expected to:

• Investigate cross-supplier theft cases
• Support prosecutions
• Monitor social media for criminal promotion
• Coordinate intelligence industry-wide

The linked Referral Assessment Service (RAS) will act as a filter, forwarding only high-quality cases to the ETU.

The unit’s annual cost will be £1.6 million, rising to £2 million with the RAS included. Ofgem claims that even a 0.33% reduction in theft would make the project cost-effective. That’s a very low bar — and a telling one.

A Long-Overdue Step in the Right Direction

While the ETU is a positive step, it’s also a stark reminder of the damage caused by regulatory neglect. Energy suppliers have been calling for support for years. The public has paid the price — in pounds, in property damage, and in lives.

Ofgem itself now admits the system was broken:

“There is no coordinated action to address cross-supplier instances of energy theft… suppliers currently have no obligation to report energy theft as a crime.”
— Ofgem

The creation of the ETU raises several questions:

• Why did it take until 2025 to act?
• Why were suppliers left without enforcement support?
• Why were consumers expected to absorb the cost?

The Energy Theft Unit could reduce crime, save lives, and lower costs — but this should have happened years ago. Consumers deserve more than a fix — they deserve accountability.

Octopus Energy have launched a new feature called Greener Days, to help show when there’s more renewable energy in the electricity mix in order to help the UK cut carbon emissions.

Greener Days are days when there’s a higher share of renewables powering the nation. You can use the Greener Days forecast to plan the best time in the coming week to hoover, do laundry, or charge your EV to help cut UK carbon dioxide emissions.

How do Octopus determine which are Greener Days?

The Octopus boffins check the forecasted wind generation for every night (23:00 – 06:00 the following morning) and calculate the Greener Days score. A score of 100 implies an especially windy night and an unusually high share of wind energy on the grid. This only happens a few times a year. Weather is hard to predict so they’re most confident about the forecast for the upcoming days.

Who can sign up to Greener Days?

Anyone can switch to Octopus Energy (and save £50 straight away!) and anyone who’s interested in their Greener Days forecast can use the forecast tool to plan ahead. You can sign up to receive a Greener Days forecast in your inbox once a week. The forecasts let you know when renewable energy generation is especially high so you can schedule your home appliances, or your EV charging if you’ve got one.

If Octopus supplies green energy how can some days be greener than others?

When you sign up with a renewable energy supplier like Octopus, they don’t pump green energy through a separate ‘green grid’ straight to your home. Instead, all energy sources – whether “green” or “dirty” – get mixed together when they’re fed through the wires that lead to your home. The reason Octopus can claim to be a ‘green’ supplier is that they buy green energy from renewable energy generators to replace the energy their customers use (making the ‘energy mix’ greener in the process) over the years. So day to day, you can still be using energy at ‘greener’ or ‘dirtier’ times. On a greener day, the share of renewable energy is especially high.

What is the benefit of Greener Days for me?

The Greener Days forecast shows you the daily energy mix of the grid. This gives you the power to decide if you’d like to use more energy on Greener Days and less on others, to help you cut your carbon emissions.

I have an EV – how can Greener Days benefit me?

If you have an EV, you can earn what Octopus Energy calls Octopoints when you charge your EV on a Greener Day. The more often you charge on Greener Days, the more Octopoints you can earn . If you’d like to go even further, tariffs like Agile Octopus and Tracker actually financially reward you for planning your energy use around the UK’s power mix. Octopus even reward streaks of Greener Days charging, with one charge a week that must be done on a Greener Day (weeks run from Monday to Sunday). You can earn up to 80 Octopoints per week.

If you’ve got an EV you might want to use our Smart Tariff Savings Calculator to check you are on the right tariff – some people have seen significant savings (up to £600) from switching.

What are Octopoints?

Octopoints are a way of rewarding Octopus Energy customers. You can earn them in different initiatives like Saving Sessions. There are 8 Octopoints to a penny. They can be redeemed for account credit (in GBP) and in the future, other stuff too.

Is there a relationship between Agile Octopus price drops and Greener Days?

Agile’s pricing is often cheaper when the energy in the grid is greener, and more expensive when energy is dirtier. Usually, when the UK’s fossil fuel generating stations have been turned on to meet high demand. But Octopus Agile is tied to wholesale prices which are impacted by a range of other factors. Read more about Octopus Agile.

Is there a relationship between Intelligent Octopus Go and Greener Days?

Intelligent Octopus Go already optimises your charges to the cheapest and greenest times every day. But because of weather changes, some days are still greener than others. Put simply, the stronger the wind, the greener the grid – and the more green electrons to fuel your EV.

Can I still charge my EV if I am away on the Greener days?

Yes. Intelligent Octopus Go will always try to schedule your charge to the greenest times of the night. 

Find out more and sign up to Octopus Energy now to save £50, get 800 Octopoints and access the Greener days forecast as well their super smart balance forecaster. Octopus customers even get to take the wheel of fortune for a spin every time they submit a meter reading!

What is the UK Energy Price Cap?

The energy price cap is a limit set by Ofgem (the energy regulator) on the maximum amount energy suppliers can charge per unit of gas and electricity. It also caps daily standing charges (the fixed amount you pay to have access to energy). It is NOT a cap on your total bill—what you pay depends on how much energy you use.

Why Does the UK Energy Price Cap Exist?

It was introduced to stop energy companies from overcharging customers on default (standard variable) tariffs. Instead of letting prices skyrocket unchecked, Ofgem reviews the cap every three months to reflect market conditions.

Why Is the UK Energy Price Cap Confusing?

A common misconception is that the price cap limits your total bill. In reality, it only sets maximum rates for unit prices (per kWh) and standing charges. The “total bill” figures you often see in headlines assume a typical household’s usage, but your actual bill depends entirely on how much energy you consume.

Ofgem often makes annoucements like this, which are entirely unhelpful to 99.9% of people:

From today, 1 October 2024, the energy price cap for a typical household that uses gas and electricity and pays by Direct Debit will go up from £1,568 to £1,717 per year. This is an increase of around 10% which adds around £12 a month to an average bill.

Who is this “typical household”? And how much energy do they consume? What type of house do they live in? And how is it heated and powered and insulated? Without knowing any of this it is impossible to tell how the yearly payment figures relate to our own situations.

Building on Ofgems unhelpful annoucements the media often picks up these figures and presents them as if they apply to everyone, which leads to even more confusion. But the truth is your bill will always be based on your own energy usage, not a fixed total.

UK Energy Price Cap Rates

The UK energy price cap changes based on wholesale energy costs and should really have been communicated using pence per kilowatt hour figures from the outset, as in the table below, which shows how the rate have changed over time:

The rates represent the maximum you can be charged, so your bill depends on your actual energy consumption, but your supplier cannot charge more than the capped rates.

How to Save Money on Your Electricity Bill

Now that we know how the price cap works, how can households actually cut costs?

1. Consider Fixed Energy Deals – Are They Worth It?

• Fixed tariffs lock in a unit price for a set period, shielding you from price hikes.
• They can be cheaper than the price cap, but only if wholesale prices are stable or falling.
• Right now, many fixed deals are hovering around the cap level, so always compare before committing.
• Check what you could save via Switchcraft, one of the simplest comparison tools.

2. Is Octopus Agile a Smart Choice?

• Octopus Agile is a dynamic tariff where electricity prices change hourly based on wholesale costs.
• If you can shift your energy use to off-peak times (e.g., charging an EV or running appliances at night), it can save you a lot of money.
• However, if prices spike and you use energy during periods of high demand, your bill could rise, so it’s best for people who can be flexible with their energy use.
• Read more about how smart tarrifs can save you money and explore Octopus Agile.

3. Simple Ways to Cut Energy Costs

We’ve published our Top 10 energy saving tips, which provide full details of ways to cut costs, but some key steps to take include:

• Improving home efficiency: Smart thermostats, LED bulbs, and proper insulation can make a big difference.
• Using appliances wisely: Wash clothes at lower temperatures, avoid standby mode, and air-dry instead of using a tumble dryer.
• Monitoring your usage: A smart meter helps track what you’re spending in real time.

Bottom Line

The energy price cap offers some protection, but it won’t always mean the cheapest bills. If you’re looking to save, compare fixed deals, consider smart tariffs like Octopus Agile, and be mindful of your energy use. Small changes can lead to big savings!

But with the UK’s often cloudy weather and the upfront costs of installation, many wonder: are solar panels truly worth it in the UK? Let’s break down the costs, benefits, savings, and practical considerations to help you decide. 

Are solar panels worth it in the UK: Costs and Savings

The initial cost of installing solar panels in the UK typically ranges from £5,000 to £12,000, depending on system size (e.g., a 4kW system for a three-bedroom home averages £6,500) – although plug in solar kits are much cheaper.

This includes panels, an inverter, and installation fees. While this might seem steep, several factors make the investment worthwhile over time.

• Energy Bill Savings: A 4kW system can generate around 3,400 kWh annually in the UK, covering roughly 50-70% of a typical household’s electricity needs (based on Ofgem’s average usage of 2,700 kWh for electricity). With electricity prices at 26p per kWh, this translates to savings of £816 per year. Over 20 years, that’s £16,320—far exceeding the initial cost.
• Smart Export Guarantee (SEG): Since the Feed-in Tariff ended in 2019, the SEG allows you to sell excess electricity back to the grid. Rates vary (e.g., Octopus Energy offers 15p per kWh), but a 4kW system might export 1,000 kWh annually, earning £150 per year, or £3,000 over 20 years.
• Rising Energy Costs: With volatile energy prices solar panels offer a hedge against future increases, locking in lower energy costs.

Environmental Benefits

Solar panels significantly reduce your carbon footprint. A 4kW system offsets around 1.5 tonnes of CO2 annually, equivalent to planting 70 trees each year. For eco-conscious homeowners, this aligns with the UK’s net-zero goals by 2050, making solar a meaningful step towards sustainability.

Practical Considerations in the UK

• Weather and Efficiency: The UK’s climate isn’t as sunny as Spain, but solar panels still work effectively. They generate electricity from daylight, not direct sunlight, and modern panels perform well even on cloudy days. Southern England (e.g., London) gets around 1,500 hours of sunshine annually, while Scotland averages 1,200 hours—still enough for decent output.
• Roof Suitability: Your roof needs to be south-facing (or near-south), with a 20-40° pitch and minimal shading for optimal performance. If your roof isn’t suitable, ground-mounted systems are an option, though they’re costlier.
• Lifespan and Maintenance: Solar panels typically last 25-30 years, with a 10-20 year warranty on most models. Maintenance is minimal—clean them annually to remove dirt, and budget £100-£200 every 5-10 years for inverter checks.

Government Incentives and Support

While the Feed-in Tariff is gone, the SEG provides export payments, and some local councils offer grants (e.g., the Home Upgrade Grant for low-income households). Additionally, solar installations are VAT-free for residential properties (0% VAT as of 2025), saving you £1,000-£2,000 upfront. If paired with a battery (e.g., AlphaESS G3, costing £3,000-£5,000), you can store excess energy for evening use, maximising savings.

Are solar panels worth it – Potential Drawbacks

• Upfront Cost: The initial investment can be a barrier, though financing options (e.g., 0% interest loans from installers like Heatable) make it more accessible.
• Break-Even Period: It takes 8-12 years to recoup your investment, depending on energy prices and SEG rates. If you plan to move house sooner, this might not suit you.
• Aesthetic Impact: Some find panels less attractive on traditional UK homes, though sleek, all-black designs are now available.

Are Solar Panels Worth It in the UK?

For most UK homeowners, solar panels are worth the investment. Financially, they pay for themselves within 8-12 years and deliver £15,000-£20,000 in savings over their lifespan, while also increasing property value (by 4% on average, per Rightmove). 

Environmentally, they’re a win, cutting your carbon footprint significantly. However, they’re not ideal for everyone—if your roof isn’t suitable, you’re moving soon, or you can’t afford the upfront cost, you might want to explore alternatives like community solar schemes.

Final Thoughts

Solar panels in the UK offer a compelling mix of financial savings, environmental benefits, and energy independence. With government support, rising energy costs, and improving technology, now is a great time to go solar.
