Solar panel grants for schools

UK schools were, until November 2024, the most heavily grant-supported solar PV sector. The Public Sector Decarbonisation Scheme funded heat-led decarbonisation for state-maintained schools and academies until its Phase 4 window closed in November 2024; no new window had opened as of September 2026. The Salix Recycling Fund has not accepted new applicants since 2010 and wound up in March 2025. The live routes are the Condition Improvement Fund for academies, SEG export income and third-party-funded PPAs, which can still deliver 15-200 kWp per school site with no capital outlay by the school budget. The challenge is access: PSDS funding rounds are heavily oversubscribed within hours of opening, and academy eligibility varies by trust type.

Why schools are buying solar in 2026

100% grant routes available

PSDS funds the full capex of qualifying projects. No school capital required.

Wider net zero commitments

UK Department for Education committed to net zero by 2050; many local authorities have earlier targets (2030-2038).

Curriculum value

Solar PV with live monitoring supports KS2 and KS3 science curriculum — common motivator for governing body support.

Holiday period export

School summer holiday + Easter + Christmas / February half-term = 13-15 weeks of high-export periods. SEG revenue covers significant fraction of operating costs.

MAT-level standardisation

Multi-academy trusts increasingly standardise solar specifications across their estate — driving procurement scale and consistent technical performance.

Sub-sector breakdown

Different parts of this sector have different load profiles, building types and grant eligibility.

  • State-maintained primary schools — Typical system 15-30 kWp. PSDS + Salix funding stack.
  • State-maintained secondary schools — Typical system 50-150 kWp. PSDS funding strong.
  • Multi-academy trusts (MATs) — Programme rollouts across 5-50 schools. Eligibility varies — check current Salix guidance.
  • Sixth-form colleges and FE — Typically 100-300 kWp. Capital programmes through ESFA + PSDS.
  • Independent / private schools — PSDS not eligible. AIA + SEG + charitable trust funding routes.
  • Special educational needs (SEN) schools — Often higher per-pupil capital allocation; LA-led.
  • Boarding schools (state) — 24/7 occupancy — higher self-consumption than day schools.
  • Free schools and academies — Variable PSDS eligibility — confirm with Salix.

Sector case study

Case study — Multi-academy trust of 22 primary schools, North East England, 2024-2025 rollout.

The trust operates 22 primary schools across Durham, Tyne & Wear and Northumberland. Average school: 350 pupils, 1,500 m² floor area, 110,000 kWh/year electricity. The trust applied for PSDS Phase 3b funding in 2023, securing £3.6m for an estate-wide decarbonisation programme. Solar PV was the largest single technology — averaging 28 kWp per school, total 615 kWp across the estate.

Capex: £2.2m for solar (excluded from PSDS competitive scoring on its own; included as part of integrated heat pump + insulation package). PSDS grant covered 100% of qualifying capex. Annual electricity import reduction across the estate: 540,000 kWh; SEG income (school holiday periods drive material export): £21,000/year combined. Annual carbon saving: 113 tCO2e. The trust now reports against its net-zero-by-2035 pledge with credible Scope 2 evidence.

Sector-specific watch-outs

  • PSDS is wildly oversubscribed. Phase 3a (Oct 2021) closed within 72 hours; subsequent phases within 24-48 hours. Be RIBA Stage 3 ready before the next window opens.
  • Academy eligibility varies. Some academy types are PSDS-eligible (LA-maintained transitioning); others (free schools, voluntary aided, foundation schools) have different rules. Check the current Salix academy eligibility list.
  • Solar-only applications underscore. PSDS prioritises heat decarbonisation. Standalone solar applications struggle — include heat pump + insulation + BMS in the package.
  • Procurement constraints. Public sector procurement rules (PCR 2015 / Procurement Act 2023) require tendered procurement above £213k. Build 8-12 weeks into the programme timeline.
  • Carbon factor changes. Grid carbon factor falls year-on-year. A project that delivered 80 tCO2e/year in 2020 saves only ~60 tCO2e/year in 2026 — strengthen the case with locked-in factors where possible.

FAQs

Solar panel grants for schools · FAQs

Can my school get 100% grant funding for solar?

Not at present. The PSDS funded solar only as part of a heat-decarbonisation bid, and its Phase 4 window closed in November 2024 with no new window open as of September 2026. Academies can bid into the Condition Improvement Fund's annual rounds; any school can use a third-party-funded PPA, which needs no capital.

What is the typical solar system size for a UK primary school?

Typical primary school rooftop solar is 15-30 kWp — depending on roof area, pitch, shading and electrical service capacity. Average annual generation 14,000-28,000 kWh, saving £3,500-£7,000/year on electricity bills.

How does Salix Recycling Fund work for schools?

It no longer does in England. The England Recycling Fund closed to new applicants in 2010 and all its funds closed on 31 March 2025. Schools in Scotland can use the Scottish Public Sector Energy Efficiency Loan Scheme at 0%, and Welsh schools the Salix Wales loan at a low fixed rate; English schools have no Salix loan route. Full Salix guide.

Can private schools get PSDS funding?

No — PSDS is for public sector bodies only. Independent schools should use the AIA route + SEG + (if registered charity) charitable trust funding routes.

Does solar affect school admissions or league tables?

No direct effect. But many parents and school governance bodies now consider environmental credentials in selection — particularly at secondary level. Solar can also support the Eco-Schools Green Flag award.
