Free solar panels for schools: is it real?
Short answer: not usually a giveaway — but near-zero net cost is genuinely achievable, and more than one route gets you there. Here is the honest version.
"Free solar panels for schools" is one of the most-searched phrases in this whole sector, and it deserves an honest answer rather than a marketing one. The blunt truth is that panels are rarely free in the sense of a lorry turning up and leaving them for nothing. What is genuinely real — and what most schools actually get — is zero net cost: the school pays little or nothing out of its own capital, because the project is funded, and the electricity saving covers the rest. There are five routes people mean by it, only some of which are open, and the right one depends on whether you are a maintained school, an academy, a trust or an independent, and on whether you have capital to spend.
The one genuinely free route is government-selected, and it selects rather than takes applications: see the Great British Energy application guide.
1. The Great British Energy schools programme
The publicly-owned Great British Energy is funding rooftop solar across England’s state schools, prioritising areas of higher deprivation first. Where a school is selected, the capital for the array is provided directly, so there is little or no upfront cost. This is the closest thing to genuinely "free" solar — but the rollout is phased and centrally allocated, so it will not reach every school in the first waves. Government contacts the schools it selects, so there is nothing to apply for; the practical move is to have your own costed case ready so the decision does not wait on selection.
2. Salix — no loan for English schools
Much of what is written about free school solar rests on a “Salix Decarbonisation Loan” — interest-free and repaid from the savings. There is no such loan for English schools in 2026: Salix’s England page lists only grant schemes, and the zero-interest public-sector loans it runs are in Scotland, with a fixed-rate programme in Wales. See Salix funding for schools for what is open in each nation.
3. PSDS — closed to new bids since November 2024
The Public Sector Decarbonisation Scheme (PSDS) was a competitive capital grant for public-sector buildings, including schools and FE colleges, administered by Salix on behalf of government. Its Phase 4 application window closed in November 2024, and the Department for Education’s guidance for 2026 to 2027 records that the government will commit no further investment for it beyond projects already awarded. It was also heat-led: solar was fundable only alongside a PSDS-funded heating replacement, never as a standalone rooftop grant.
4. The Condition Improvement Fund (CIF) for academies
Stand-alone academies, trusts with fewer than five schools or fewer than 3,000 pupils, qualifying voluntary aided schools and sixth-form colleges can bid into the annual Condition Improvement Fund. It is a condition fund: compliance, health and safety, critical boiler replacement and weather-tightness come first, and the guidance says energy-efficiency-only works are unlikely to succeed. Solar can be designed in alongside a genuine roof or heating project, but CIF will not usually pay for an array on a sound roof.
5. A solar PPA — genuinely zero upfront
If you want the bill saving without spending capital or touching your borrowing headroom, a power purchase agreement (PPA) is the true zero-upfront route. A third party funds, owns and maintains the system on your roof, and the school simply buys the electricity it generates at a price below the grid rate. No capital, no loan on the balance sheet, no maintenance liability during the term. It is a particularly good fit for trusts protecting their capital for teaching priorities — you can read the specifics of the school and academy PPA model at solarpowerpurchaseagreements.co.uk.
So what does "free" honestly mean?
Put plainly: for most UK schools, “free solar panels” is either government selection, which you cannot apply for, or a power purchase agreement, where you pay for the electricity rather than the panels. Everything else — CIF alongside a roof project, or buying from capital — costs the school money, and buying outright is often the best value over the life of the panels. Get your actual cost and payback modelled from at least twelve months of your half-hourly meter data before you choose. If you are looking for grants rather than free panels, see green energy grants for schools.
Free solar for schools — FAQs
Are free solar panels for schools actually free?
Only for schools the government selects. By July 2026, 245 schools and colleges had government-funded panels, and 150 more in Yorkshire and the Humber, the East Midlands and the South East are piloting installs at no upfront cost. For everyone else, “free” means a power purchase agreement — no capital, but the school buys the electricity. There is no Salix loan for English schools, and PSDS closed to new applications in November 2024.
What is the cheapest way for a state school to get solar with no upfront cost?
If the school is not selected for government funding, a power purchase agreement is the only no-upfront route: the funder owns and maintains the system and the school buys the power at an agreed price. From 15 July 2026 any PPA on the school estate must use the DfE’s PPA and land-lease templates, which had still not been published when we checked on 18 October 2026 (DfE expects them in autumn 2026). Over the life of the panels, buying from capital usually costs less.
Can academies get free or grant-funded solar panels?
Some can get CIF funding, but not for solar on its own. Stand-alone academies and trusts with fewer than five schools or fewer than 3,000 pupils can bid into the Condition Improvement Fund, which funds condition work and treats energy-efficiency-only projects as low priority — so solar is best designed in alongside a genuine roof or heating project. Larger trusts receive School Condition Allocation instead.
Is there a Salix loan for schools?
There is no Salix loan for English schools to pay back. Salix runs zero-interest public-sector loans in Scotland, and the Wales Funding Programme lends to Welsh public bodies at a fixed rate; in England its current schemes are grants. See Salix funding for schools.
What is a solar PPA and does it really cost nothing upfront?
A power purchase agreement (PPA) is genuinely zero upfront: a third party funds, owns and maintains the system on your roof, and the school simply buys the electricity it generates at a price below the grid rate. There is no capital, no loan on your balance sheet and no maintenance liability during the term. It suits schools and trusts that want the bill saving without spending capital or using borrowing headroom.
Free solar panels for schools: what is free, and what you still pay
There is no open application for free solar panels. The nearest route is the Great British Energy schools programme, where government selects schools rather than inviting bids: 245 schools and colleges already have government-funded panels, and a further 100 are joining backed by up to £40 million. Every other route is funded, not free — it is bid for, borrowed, or bought back as electricity. One change is worth watching — and it is the PPA model explained on our community energy page: 150 schools across Yorkshire and Humber, the East Midlands and the South East are piloting a model where a private company installs and maintains the panels at no upfront cost and the school buys the power at a rate government describes as significantly cheaper than its normal tariff. That pilot is intended to inform a national rollout from 2027 to 2028, with the stated ambition that every school and college in England will eventually be able to access solar.
| Route | Can your school apply? | Who pays | The catch nobody quotes |
|---|---|---|---|
| Great British Energy schools programme | No — schools are selected | Great British Energy and government | Clustered on areas of deprivation in the North East, West Midlands and North West, plus at least 10 schools per English region. |
| No-upfront-cost pilot (150 schools) | Not yet — pilot regions named | A private company, which owns and maintains the panels | You buy the power, so it is a PPA in substance. A wider rollout from 2027 to 2028 is an ambition, not a commitment. |
| Public Sector Decarbonisation Scheme | No — closed to new applications since November 2024 | Capital grant, delivered by Salix for DESNZ | Heat-decarbonisation led — solar is funded alongside a heat measure, not as a standalone roof array. England only. Phase 4 is in delivery and earlier phases are closed; Salix states many of its programmes may be closed for applications. |
| Condition Improvement Fund | Yes, in the annual round | DfE capital funding | Academies, sixth-form colleges and voluntary aided schools in England only; 2026 to 2027 outcomes were announced on 22 May 2026, so the next opportunity is the following round. |
| Solar power purchase agreement (PPA) | Yes — a commercial deal, not a bid | A third-party funder, which owns the system | You buy the power for the term, so value tracks what the school consumes, not what the roof generates. |
| Buying outright | Always available | Your capital or borrowing | Invoiced at 20% VAT, or 0% where a charity-run, non-fee-paying school building qualifies — and where 20% is charged most state schools then recover it, so check recovery before comparing quotes. |
Do schools get 0% VAT on solar panels?
Check which rate applies before you budget. The zero rate for installing energy-saving materials is narrow: it applies to residential accommodation and, since 1 February 2024, to buildings intended for use solely for a relevant charitable purpose, and it runs only to 31 March 2027 before reverting to the reduced rate of 5%. That can reach the residential parts of a boarding school, or the buildings of a non-fee-paying academy or other charity-run school used solely for non-business purposes — it is not a blanket school rate (local-authority-maintained community schools and the teaching buildings of fee-charging independent schools pay the standard 20% rate), and it is a question for your VAT adviser about the specific building rather than an assumption to build into a budget. Recovery usually matters more than the rate: an academy or multi-academy trust that is not registered for VAT can reclaim VAT on non-business spending through HMRC’s VAT126 service, submitted within 4 years after the end of the month in which the supply was received, while a local-authority-maintained school recovers through the council’s section 33 route. Our note on how VAT lands on a school solar invoice works through both.
Will the grid let us fit as much as the roof holds?
Funding is only half the gate. The array must also be accepted by your Distribution Network Operator. The simple notify-afterwards route (G98) covers installations of up to 3.68 kW per phase — equivalent to 16 A per phase; above 3.68 kW per phase and up to 50 kW, the G99 route applies and the network operator determines what the local network will accept before the system is energised. A single-phase supply, common in older primaries, reaches that threshold well below what the roof could physically hold — the network operator, not the funder, sets the ceiling. Establish the DNO position before you cost a scheme.
What happens over the summer holidays?
Generation peaks across the summer while the building is largely empty, so much of a funded array’s August output is exported rather than used on site. That matters most under a PPA or the no-upfront pilot model, where the benefit is the power you actually consume. Exported units are paid under the Smart Export Guarantee, where Ofgem requires that tariff rates always be above zero but the licensee determines the rate, contract length and other terms — so the export price is a commercial negotiation, not a fixed government figure. See what a school earns for exported units.
