Schools solar in figures

Every figure below comes from a named public source, the same standard we hold our savings estimates to.

  • Education is the largest emitting part of the public sector building estate in England, accounting for 37% of public sector building emissions, 13% from state primary schools, 11% from state secondary schools and 13% from universities.

  • The DfE oversees around 21,600 maintained schools in England: more than 11,400 run by local authorities and more than 10,200 academies within single or multi-academy trusts, so ownership, consent and procurement routes differ significantly from site to site.

  • The DfE's Asbestos Management Assurance Process surveyed 22,072 state-funded schools in England; 88.4% responded and 80.9% of participating schools reported some asbestos present on site.

  • Schools in England must open for at least 380 half-day sessions: 190 days: each school year, so a school building is fully occupied for roughly 39 weeks and closed for around 13, including most of the highest-generating summer weeks.

  • The Condition Improvement Fund made over £450 million available for the 2026 to 2027 round, with outcomes announced on 22 May 2026 covering 813 projects at 684 establishments. Eligibility is limited to standalone academies, sixth-form colleges, voluntary-aided schools and MATs with fewer than five schools or fewer than 3,000 pupils.

  • Great British Energy's schools solar programme committed around £80 million to roughly 200 schools; 100 schools and colleges had completed installations as at 5 March 2026, with around 250 expected by summer 2026, targeted at clusters of deprivation in the North East, West Midlands and North West.

  • Salix's Public Sector Decarbonisation Scheme Phase 4 is open to maintained schools, academies, multi-academy trusts and free schools, with capital funding running from 2025/26 and all projects required to be delivered by 31 March 2028.

  • The DfE's Sustainability and Climate Change Strategy set the expectation that every education setting in England appoints a sustainability lead and puts a Climate Action Plan in place, giving schools a documented reason to evidence on-site generation.

  • Onsite renewable generation and connected storage in England is exempt from business rates until 31 March 2035, so a rooftop array does not increase a school's rateable value during that period.

  • Most commercial rooftop solar in England is permitted development; the previous 1MW cap on rooftop installations was removed in November 2023, though listed buildings and conservation areas, common among Victorian board schools, still require consent.

Schools solar questions

Does solar still pay back if the school is closed for the whole summer holiday?
Will a battery let us store summer generation for the autumn term?
What happens if there is asbestos in our roof or ceiling voids?
Do we need planning permission, and who has to consent to the works?
What funding routes are available to schools and academy trusts?
When would the work actually happen, and how disruptive is it?
Can we use the system as a teaching resource?
