Mayor of London Greener Schools programme

The Greener Schools pilot funds capital net zero interventions in London state schools, including rooftop solar PV, heat pumps and building retrofit, plus pupil-facing climate education delivered with partners such as RAFT and Students Organising for Sustainability UK. A separate Mayoral renewables allocation supports larger renewable-energy generation at schools.

In April 2025 the pilot awarded 38 schools across 16 London boroughs, including special schools, nurseries, primaries and secondaries. Eligibility runs through the London boroughs; refer to the current Greener Schools programme guidance for the live application route and future cycles.

Across the 38 pilot schools the award averaged over £77,000 per school, with capital grants of up to £500,000 per project. The Mayor's office estimates participating schools could save up to around £15,000 a year on energy bills.

Greener Schools grant can pair with PSDS and Salix funding on a bundled scope, for example covering the solar PV element while PSDS covers heat decarbonisation. Match-funding and eligibility rules differ between the two; confirm against the most recent Mayor's office and Salix guidance before assuming a stack.
