• 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• There will be a six-month transition period, with the previous version withdrawn on 15 October 2026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 post What is plug in solar appeared first on Smart Home Energy.

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.

British households generated a record £31 million from rooftop solar panels through Ofgem’s Smart Export Guarantee (SEG) scheme in 2023. The initiative pays households for exporting surplus renewable energy back to the grid, and the earnings reflect a growing interest in renewable energy, spurred by rising electricity costs and a surge in solar installations.

Growth in Solar Energy Adoption

A substantial shift towards renewable energy followed recent electricity price hikes and reduced solar panel installation costs. Households increasingly turned to rooftop solar as a reliable way to save money, especially as the Conservative government eliminated VAT on solar panels in 2022, further reducing initial installation expenses. Demand for solar panels has spiked in recent years, driven by both the need for energy independence and the rising cost of living.

To support this transition, Ed Miliband, the Energy Secretary, has advocated a “rooftop revolution” aimed at tripling the country’s solar capacity. Miliband has said that solar panels represent a “win-win technology,” providing both environmental and financial benefits.

How the SEG Scheme Works

The Smart Export Guarantee (SEG) allows households to sell unused solar energy back to energy suppliers, with energy providers required to offer an export tariff for these contributions. Providers set their own rates, meaning that payouts can vary depending on the chosen tariff. In 2023, the SEG scheme distributed nearly £30.7 million to 283,666 households, a significant jump from the 92,946 participants in 2022.

The SEG is structured to be cost-effective for taxpayers because it’s not subsidised by public funds. Households contribute their excess energy at rates set by energy providers, which allows flexibility in payments based on market dynamics. This approach has led to greater diversity in tariff offerings, with some rates more favorable than others. For example, some providers offer rates as high as 27p per kilowatt-hour, but this typically requires the household to have additional green energy solutions like home batteries or electric vehicles.

On average, households received 13p per kilowatt-hour last year, though more common, straightforward plans provided approximately 5.7p per kilowatt-hour. When compared to the average electricity purchase rate of 24.5p per kilowatt-hour under the energy price cap, it’s a modest payment. However, for households already seeing savings on bills due to solar, the SEG payments are an added benefit.

Solar’s Impact Across the UK

Last year, SEG participants exported 238 gigawatt hours to the grid, which is enough to power nearly 88,200 homes for an entire year. Nearly all SEG participants—99.98%—are using rooftop solar panels, with only a few using alternative renewable sources such as small wind or hydropower installations. Solar installations are especially popular in the South of England, where daylight hours are longer, allowing for more power generation.

Financial Benefits of Solar Installations

For most households, solar panels represent a longer-term investment. Installations typically cost around £5,000 or more, with savings building up over time through reduced energy bills and SEG payments. The Energy Saving Trust estimates that households in London could reach profit on their investment in about 11-12 years, while households in Scotland might take up to 14 years due to lower sunlight levels. Although the payback period might seem lengthy, it’s offset by the immediate reduction in electricity bills and protection against energy price volatility. Plus, solar panels have performance guarantees for 25 years so once the system has paid for itself it will continue to generate profits for at least another decade.

SEG earnings can range based on the size of the installation, usage, and chosen tariff. With an average household earning around £108 annually, larger systems and households with high energy usage tend to see better returns.

Looking Forward

The record earnings from solar PV in 2023 demonstrates solar energy’s potential for financial and environmental impact. As the market continues to expand, more households are likely to consider solar as a viable energy option, not only to reduce their bills but also to contribute to a sustainable energy grid. As long as the government don’t mess things up, the UK is poised for a continued “rooftop revolution,” making solar energy accessible, profitable, and an essential part of Britain’s renewable energy landscape.

Not every home is suitable for solar – and people that live in flats without roof space are not able to install solar panels. But now, thanks to Ripple Energy, anyone can invest in wind or solar projects to reduce their electricity bills.

How does Ripple Energy work?

1. Visit Ripple Energy to get a quote for your home
2. Decide how much of your electricity you want to buy from Ripple, which will determine how much of the solar park you own, the cost of your investment and your predicted savings
3. Create your Ripple account, choose whether to pay all at once or via monthly installments and make your initial payment to become a co-owner of the solar park
4. Ripple build the solar farm and sell the electricity which is generated to your supplier via a Power Purchase Agreement – i.e. at a fixed, low price (in comparison to the standard wholesale price of electricity)
5. Your energy company passes on the savings to you as a discount on your bill
6. The savings continue for the 40 year life of the solar park and you can track how much energy your share of the solar park has generated through the Ripple Members’ dashboard

You will need to be with, or switch to, one of Ripple’s supply partners, which are E-on and Octopus, but since Octopus currently offer some of the cheapest smart tariffs – and a £50 credit for switching – that’s not a problem.

How much can you save via Ripple Energy?

It’s hard to say exactly how much you will save over the lifetime of your investment because savings are dependent on wholesale electricity prices, which vary over time. Your savings will be the difference between the price Ripple sells the energy to your supplier and the market price.

Ripple’s savings calculator assumes an average member saving of just 6.1p/kWh. But this rate will vary each year according to the price Ripple secures for the PPAs they negotiate with the energy suppliers and the market price of electricity.

Their standard quote, for a home consuming 2,900kWhs of electricity per year, for which they recommend you buy 2,958 Watts of the solar park, is £3,044 which should produce roughly 100% of the electricity you consume, saving you a £288 in the first year (once the solar park is completed in 2025) and £6,816 over the 40 year lifespan of the project. This equates to a 17 year payback. These figures are based on the assumptions of the “extended high” pathway from the latest BEIS figures which are fairly conservative in our opinion. 

Ripple has already built 2 wind farms which are co-owned in the same way and the savings have far exceeded their estimates – mainly because electricity prices shot up last year, so the savings rose too. For example, someone who invested £323.37 in the Graig Fartha in 2021 to cover just 10% of their bill would have saved £60 in the first year and £180 in 2022, implying total payback in year 3 and 22 more years of savings (the wind farm contracts only run for 25 years). So that’s an amazing payback period – and very significant savings.

However, as mentioned above, whilst savings will be high in years when the wholesale price of electricity is high, in years when the electricity price is lower the level of savings would be lower too. If you select the ‘low’ estimate for future energy prices on Ripple’s payback calculator the estimated payback period extends to 29 years, which still implies 11 years of savings at ~1.7% pa which is still worthwhile, especially if you also want to help reduce carbon emissions.

Whichever way you look at it you will save money over the duration of the project – and you don’t need to worry about moving house because you can transfer your savings to your new home, or dying because in the event of your death your shares can be inherited by someone else.

If energy prices continue to rise, which seems highly likely as we transition to net zero and the UK needs double, or even triple the amount of electricity we currently consume by 2050 the return on investment from investing in Ripple would be significant.

If wholesale prices remained high and the Ripple Energy savings rate was ~15p you could be looking at a 12% return per annum.

Why else should you invest?

Aside from the financial savings, which we think will exceed Ripple’s estimates, investing in solar and wind parks is an obvious way to do more to reduce UK carbon emissions. Investing your money will help brings these renewable energy sources online quicker, will create green jobs and will also help prove that this groundbreaking model works. Perhaps then the government might start to take notice and approve the Local Electricity Bill to make it easier for other community energy projects to sell the energy they generate to local consumers at a fair price.

Is Ripple Energy a good investment:

Ripple Energy is trailblazing a new model for the public ownership of renewable energy assets which offers significant savings over the long term, as well as supporting carbon reduction. Just a few hundred pounds will cover ~10% of your consumption and will help stabilise your electricity bill over the long term making it a good investment.

Further details:

There is a lot of innovation behind the scenes to make Ripple’s projects viable. They have an extensive FAQ section which answers a lot of questions but as part of our Ripple Energy review Smart Home Energy contacted Ripple directly to dig into some of the details which aren’t covered in the FAQ, which our more analytical readers might be wondering about:

To start with we wanted to know how their model accommodates the reduction in energy production as the PV degrades over time because in year 25 the panels will be producing much less than in year 1. Ripple replied:

“Yes the figures provided take into account a small amount of degradation and reflect the yield we expect to see over the lifespan of the project.”

We also asked, why are they aiming to pay back part of the share capital each year? And why does this happen at different rates for wind and solar farms? (For wind farms, this will tend to be 5% per year, and 3% for solar parks) Ripple replied:

“The share capital is gradually repaid to ensure the value of share capital broadly reflects the actual value of the solar park (which gradually reduces over its lifetime). The value of the share withdrawals forms part of member savings. Solar and wind are different because the lifespans of the projects are different.”

This makes a lot of sense, because presumably it will then be easier to wind down the co-ops at the end of the projects.

We also asked if any other supply partners are likely to come on board other than E-On and Octopus? Ripple replied:

“Yes we are looking to bring on other suppliers.”

Not great detail there! But promising…

What are the project’s predicted operating costs? Ripple replied:

“2p/kWh”

This is good to hear because it is a reasonable amount for running a solar farm so we can assume the operating costs are easily covered in their model and there should not be any nasty surprises for investors.

Does it make any difference if a customer is on a TOU, or dynamic tariff? Ripple replied:

“No, they can be on any tariff with our supply partners – their savings are simply based on how much their share of the project generates.”

Good news here too!

Are there more Ripple projects (wind or solar) in the pipeline? Ripple replied:

“Yes. We are looking at both wind and solar for future projects and are hoping to launch another one this year.”

This is also good news as well which means more savings for potential investors and more UK carbon reductions.

Ripple Energy review – final thoughts:

Overall, we are very impressed by what Ripple Energy is doing and are confident to recommend them as a safe investment.

The brief explosion of community energy schemes – community-owned and run renewable energy generation projects – driven by the Feed-in Tariff has now dwindled to a trickle. This is despite renewable technologies being cheaper than ever and is largely the result of the prohibitive costs small-scale generators face in accessing markets to sell the electricity they produce.

The potential for community energy to benefit local economies is being blocked by unfair regulations and hugely disproportionate costs. 

Power For People have drafted the Local Electricity Bill and are campaigning for it to be made law. This would give small-scale renewable energy a massive boost by empowering communities to sell their energy directly to local people.

Together with leading industry experts, Power To People have developed two proposals for legislation to support community energy schemes, these are:

1. A Community and Smaller-scale Electricity Export Guarantee Scheme: a right for sites that generate low carbon electricity with a capacity below 5 megawatts to export their electricity to an existing larger electricity supplier on fair terms (Amendment Number 134).
2. A Community and Smaller-scale Electricity Supplier Services Scheme: a requirement on existing larger suppliers to work with community schemes to sell the power they generate to local customers. Existing suppliers can charge a fee for doing this, but that fee must be reasonable (Amendment Number 135).

After a successful vote in the House of Lords a few weeks ago, the campaign is making progress. The vote means that the legislation is now in the Government’s Energy Bill as clauses 272 and 273. The Energy Bill next moves to the House of Commons but we need to make sure the clauses stay in the bill.

If you think the UK would benefit from more community energy schemes please add your voice to the debate by writing to your MP and asking them to attend the Energy Bill’s Second Reading on 9th May and speak in favour of clauses 272 and 273 that enable community renewable energy.

A one-line email would be enough – the most important thing is that they hear from you.

The problem is well recognised, with 318 MPs from all parties backing the Local Electricity Bill, aimed at helping community groups sell the electricity they generate to local customers. The Bill is also supported by over 110 principal councils and over 80 national organisations including the National Trust, the Church of England, CPRE, the Energy Saving Trust, the RSPB, WWF, Greenpeace and Friends of the Earth.

The community energy sector could grow by 12-20 times by 2030, powering 2.2 million homes and saving 2.5 million tonnes of CO2 emissions every year. If achieved, this would take community-owned and run renewable energy generation to 10% of UK electricity generation (around 6,000 megawatts).

Ripple Energy are trailblazing a new model for community ownership of solar and wind farms – see our Ripple Energy review – but we still need the Local Electricity Bill to open up the community energy sector.

The Microgeneration Certification Scheme (MCS) is a UK-based scheme that certifies renewable energy products and installers. 

The aim of MCS is to give people confidence in low-carbon energy technology by defining, maintaining and improving quality.

Products and installers that have been verified use the MCS mark to demonstrate quality, competency and compliance.

Plug in solar is not expected to require an MCS installer but may require you use MCS certified products.

If you are planning to invest in a renewable energy system read our post exploring are solar panels worth it in the UK and check out the MCS website to to find an MCS certified installer that operates in your area and to find MCS certified products.

What is the Microgeneration Certification Scheme mark?

The Microgeneration Certification Scheme mark is designed to provide reassurance that an installer or product is certified. The image on the left shows the new (as of 2022) certification mark, however, while the rollout of the new brand takes place, you might still see the old certification mark (the image on the right).

Which technologies does the Microgeneration Certification Scheme cover?

MCS covers a range of renewable energy technologies that generate heat and/or electricity from sources that are constantly replenished, such as the sun, wind or water.

The MCS covers the following renewable energy technologies – also known as low carbon technologies:

• Solar Photovoltaics (PV)
• Battery Storage
• Wind Turbines
• Biomass
• Solar Heating
• Solar Assisted Heat Pumps
• Ground/Water Source Heat Pumps
• Air Source Heat Pumps
• Micro CHP
• Exhaust Air Heat Pumps

How do I get a solar MCS certificate?

When your installer finishes your renewable energy installation they should issue your MCS certificate within 10-working days of the work being completed. You can check whether an MCS certificate exists by calling the MCS Helpdesk on 0333 103 8130.

Is an MCS certificate the same as building regulations?

No. MCS installations fall under the scope of Building Regulations and as part of completion arrangements evidence must be provided of a work completion certificate issued by a local authority or self-certification of the installation works by a member of a competent person’s scheme – this is a separate process from MCS.

How do I get Microgeneration Certification?

There are four main steps to becoming an MCS certified Installer. To become MCS certified an installer must demonstrate:

1. A commitment to quality workmanship
2. A commitment to customer care
3. Competency
4. A commitment to continual improvement via an effective management system

Installation companies are assessed by a Certification Body to ensure that they meet the MCS standards. The Certification Body assesses companies to determine their company practices and performs an inspection of an installation. Certification Bodies have different prices for becoming certified, and timescales can also differ for the assessment. MCS recommends that you contact a few to decide which is best for your business. See the full list of MCS Certification Bodies.
