How the figures are gathered
- Roof output: PVGIS 5.3, the European Commission's solar model, for 12 points from Otley to Wetherby, in eight directions, plus a pitch grid for the city centre.
- Prices: the Department for Energy Security and Net Zero's yearly solar and battery cost statistics for Yorkshire and the Humber.
- Homes: the 2021 Census, Valuation Office Agency build dates, ONS EPC analysis and the UK House Price Index.
- Rules and schemes: legislation.gov.uk, Leeds City Council, Historic England, Northern Powergrid, Ofgem, HMRC and the Met Office.
Each figure links to its source where it appears. Where we multiply or compare published numbers, the page says "our arithmetic". Everything was last checked on 3 November 2026.
How to check a firm yourself
We do not recommend installers, so we set out the checks instead: a written quote broken down item by item, MCS certification, membership of RECC, HIES or another approved code, a Companies House entry that tallies, and workmanship cover backed by insurance. They are all in choosing an installer.
What this guide is not
- An installer: we do not survey, fit or quote.
- Leeds City Council, Warm Homes Leeds, Northern Powergrid or the government; we run no grant or loan.
- Accredited by any trade body, or rated or reviewed by ourselves.
- Reachable by phone: the form is how to contact us.
