How Schools Get Solar Panels for Free
There are three principal routes through which UK schools can obtain solar panels at no cost. Each route works differently, has different eligibility criteria, and offers different long-term outcomes. The best option for your school depends on whether you are a state-funded or independent institution, the size of your roof, and your preferences around panel ownership. Below is a summary of each route, with links to our detailed guides for further reading.
Great British Energy Grants
100% funded, up to £150,000
The most generous option available. Great British Energy provides outright grants that cover the entire cost of solar panel installation, including equipment, labour, grid connection, and five years of maintenance. No repayment is required. The school owns the panels from day one and keeps one hundred percent of the energy savings. This programme is part of the government's eighty million pound investment in school solar energy.

Community-funded, zero cost to school
Local community groups raise investment from residents to fund solar panels on school roofs. The school pays nothing for the installation and receives discounted electricity throughout the contract period. A community benefit fund supports local environmental projects, and pupils gain access to educational resources about renewable energy. This model is open to all school types and builds strong community relationships.

Third party pays, school buys cheaper electricity
A commercial investor installs and owns solar panels on your school roof at no cost to you. Your school then purchases the electricity generated at a rate ten to twenty-five percent below the grid price. The investor handles all maintenance for the duration of the fifteen to twenty-five year contract. This option is available to every school type, making it ideal for independent schools that cannot access government grants.
Full PPA guideGovernment Grants That Cover 100% of Costs
The single most important development for schools seeking free solar panels is the Great British Energy Schools Programme. This is a dedicated government grant programme backed by eighty million pounds of public funding, designed specifically to put solar panels on school roofs across England and Wales. Unlike loans or PPAs, GBE grants are outright gifts of public money that do not need to be repaid under any circumstances. The school receives the panels, owns them from the moment they are installed, and keeps every penny of energy savings generated over the system's twenty-five to thirty year lifespan.
Each school can receive up to one hundred and fifty thousand pounds of funding, which is typically enough to cover a full rooftop installation including solar panels, inverters, mounting equipment, all electrical works, grid connection, scaffolding, and even an energy monitoring display for the school reception. Additionally, the grant includes five years of maintenance and monitoring at no extra cost to the school. This means that for at least the first five years, your school has absolutely zero costs and zero responsibilities related to the solar installation while benefiting from significant energy bill reductions.
The programme is open to all state-funded schools in England and Wales, including local authority maintained schools, academy trusts, free schools, and special schools. Applications for the 2026 round are now open and are processed on a first-come, first-served basis. Given the high demand for this funding, we strongly recommend registering your interest as early as possible to secure your school's place. Schools in areas of higher deprivation and those with the highest energy costs relative to their budget receive priority consideration.
Zero-Interest Loans: Effectively Free Solar
While not technically a grant, Salix Finance provides zero-interest loans to public sector organisations including schools for energy efficiency improvements such as solar panel installations. Because the loan carries no interest whatsoever, the repayments are funded entirely from the energy savings generated by the solar panels. In practical terms, this means the school pays nothing upfront, makes loan repayments that are less than or equal to the energy savings, and once the loan is fully repaid, keeps one hundred percent of the savings for the remaining lifespan of the system.
For most schools, a Salix-funded solar installation is cash-flow positive from year one. This means the annual energy savings exceed the annual loan repayments, so the school is better off financially every single year of the loan. Once the loan is repaid, typically within eight to twelve years, the school owns the panels outright and benefits from the full value of energy savings for the remaining fifteen to twenty years of the system's life. Over twenty-five years, the total financial benefit of a Salix-funded installation is very similar to that of a GBE grant, making it an excellent alternative for schools that do not secure GBE funding.
Salix Finance is available to local authority maintained schools, academy trusts, and further education colleges across England. Scottish, Welsh, and Northern Irish schools may have access to equivalent programmes through their devolved administrations.

How Much Can Your School Save?
The financial savings from free solar panels depend on your school's size, electricity consumption, roof area, and which funding route you choose. However, the figures are substantial regardless of which option you pursue. Solar panels generate the most electricity during school hours, which is precisely when your school is consuming the most energy. This alignment between generation and consumption means that the vast majority of solar electricity is used on-site rather than exported, maximising the financial benefit.
Primary School
£3,000-£5,000
Annual saving with a typical 20-30kWp system. Over twenty-five years, total savings of seventy-five thousand to one hundred and twenty-five thousand pounds.
Secondary School
£8,000-£15,000
Annual saving with a typical 50-100kWp system. Over twenty-five years, total savings of two hundred thousand to three hundred and seventy-five thousand pounds.
Large Academy or College
£15,000-£25,000
Annual saving with a 100kWp or larger system. Over twenty-five years, total savings of three hundred and seventy-five thousand to six hundred thousand pounds.
These figures are based on current electricity prices and assume the school consumes the majority of the solar electricity on-site. With energy prices expected to continue rising over the coming decades, actual savings are likely to be higher than these estimates. Use our energy calculator to get a personalised savings estimate for your specific school based on your roof size, electricity consumption, and location.
What's the Catch?
This is the question we hear most often, and it is entirely reasonable to ask. When something sounds too good to be true, it usually is. However, free solar panels for schools through government grants genuinely are as good as they sound. Here is a transparent breakdown of each option so you can make a fully informed decision.
Great British Energy Grants: No Catch
GBE grants are funded by the taxpayer through the government's clean energy budget. The government's motivation is to reduce carbon emissions from the public sector and lower energy costs for schools. There is no repayment, no ongoing obligation, and no strings attached beyond using the funding for its intended purpose. The school owns the panels outright, keeps all the savings, and benefits from the installation for decades. The only limitation is that funding is allocated on a first-come, first-served basis, so the real risk is not applying quickly enough and missing out on this round of funding.
Salix Loans: Very Low Catch
Salix loans carry zero interest, so you are only repaying the original amount borrowed. The loan repayments are structured to be lower than or equal to the energy savings from the solar panels, so the school is cash-flow positive from year one. The only commitment is to repay the loan over the agreed term, typically eight to twelve years. After that, all savings belong entirely to the school. The risk is minimal because even if energy prices fell significantly, the loan repayments remain fixed and manageable.
PPAs and Community Energy: Know the Trade-Off
With Power Purchase Agreements and community energy schemes, the trade-off is clear: you get solar panels for free, but you do not own them. Instead, you purchase the solar electricity at a discounted rate. Your savings are real but smaller than they would be if you owned the panels outright. Over the fifteen to twenty-five year contract, you save money compared with grid electricity, but the majority of the financial benefit goes to the investor or community group. At the end of the contract, most agreements offer you the option to purchase the panels at a significantly reduced price. This is not a scam or a hidden cost; it is simply the business model that makes zero-upfront-cost solar possible for schools that cannot access grants.
How to Apply: Step by Step
Getting free solar panels for your school is straightforward. The process varies slightly depending on which funding route you choose, but the general steps are similar across all programmes. Our team can guide you through every stage of the process at no cost.
Check Your Eligibility
Start by determining which funding routes your school qualifies for. State-funded schools should explore Great British Energy first as it offers the best financial outcome. Independent schools should look at PPAs and community energy. Use the eligibility checklist above or request a free assessment from our team to get personalised advice on the best route for your school.
Get a Free Site Assessment
A qualified surveyor visits your school to assess your roof condition, orientation, shading, structural capacity, and electrical infrastructure. For GBE-funded installations, this survey is provided at no charge as part of the programme. For other routes, our team can arrange a free initial assessment to determine whether your site is suitable for solar panels and estimate the system size and savings.
Receive Your Proposal
Based on the site assessment, you receive a detailed proposal showing the recommended system size, projected energy generation, estimated annual savings, and the funding structure. For GBE applications, this includes the grant amount. For PPAs, this includes the proposed electricity rate and contract terms. For Salix, this includes the loan amount and repayment schedule.
Approve and Install
Once you approve the proposal and the funding is confirmed, installation is scheduled at a time that minimises disruption to the school. Most installations take place during school holidays and are completed within one to three weeks depending on the system size. The installation team handles everything from scaffolding and panel mounting to electrical connection and grid commissioning.
Start Saving
From the moment the system is switched on, your school begins generating its own electricity and reducing its energy bills. An energy monitoring system allows staff and pupils to track generation in real time, and the data can be integrated into science and maths lessons. Your school also benefits from reduced carbon emissions, contributing to your sustainability targets and eco-school credentials.
Frequently Asked Questions
Are free solar panels for schools really free?
Yes, through the Great British Energy Schools Programme, state-funded schools can receive solar panels at absolutely no cost. The grant covers one hundred percent of the installation including panels, inverters, mounting equipment, electrical works, and five years of maintenance. There is no repayment required and no hidden costs. For schools using PPAs or community energy, the installation is free but you purchase the solar electricity at a discounted rate rather than receiving it entirely free. In all cases, the school pays nothing upfront.
Can independent schools get free solar panels?
Independent and private schools are not eligible for government grants through Great British Energy or loans through Salix Finance. However, they can still get solar panels installed at zero upfront cost through a Power Purchase Agreement or a community energy scheme. Under these arrangements, the school pays nothing for the installation and buys the generated electricity at a discounted rate. Many independent schools across the United Kingdom have successfully adopted solar through these routes.
How long does it take to get free solar panels installed on a school?
The timeline depends on the funding route. Great British Energy applications typically take three to six months from expression of interest to installation. Salix Finance applications can be processed in as little as four to eight weeks. PPAs typically take three to six months to arrange. Community energy schemes take the longest at twelve to eighteen months because they involve community engagement and share offers. The physical installation itself usually takes one to three weeks and is often scheduled during school holidays to minimise disruption to teaching.
Do schools need planning permission for solar panels?
In most cases, rooftop solar panels on schools benefit from permitted development rights and do not require a full planning application. There are exceptions for listed buildings, schools in conservation areas, and some ground-mounted installations. If your school does require planning permission, the cost is covered by the GBE grant for eligible schools, and most PPA providers include planning costs in their proposal. Planning should not be a barrier to getting free solar panels for your school.
What happens to the solar panels if the school closes or changes status?
For GBE-funded installations, the panels are owned by the school and would transfer with the building in the event of a change of status. For Salix-funded installations, the outstanding loan balance would need to be addressed as part of any change of status process. For PPAs and community energy schemes, the contract typically includes provisions for change of control, assignment of the agreement to a successor organisation, or early termination. We recommend reviewing these provisions carefully and seeking legal advice before entering into any long-term agreement.
