Where the numbers come from
- Output: the European Commission's PVGIS 5.3 model, run for 12 points across Liverpool and for every direction and pitch in the city centre.
- Prices: the Department for Energy Security and Net Zero's annual solar and battery cost statistics for the North West.
- Homes: the 2021 Census, Valuation Office Agency build periods, ONS EPC analysis and the UK House Price Index.
- Rules and schemes: legislation.gov.uk, Liverpool City Council, Historic England, SP Energy Networks, Ofgem, HMRC and the Met Office.
Every figure links to its source where it is used, and anything we have calculated says "our arithmetic". All figures were last checked on 3 November 2026.
How we treat installers
We do not name or rate firms. Instead we set out the checks: a quote itemised in writing, MCS registration, membership of RECC, HIES or another approved code, a matching Companies House entry, and an insurance-backed workmanship warranty. See finding an installer.
What it is not
- Not an installer: no surveys, fitting or quotes of our own.
- Not Liverpool City Council, the Combined Authority, SP Energy Networks or the government; we run no scheme.
- Not accredited by any trade body, and we publish no ratings of ourselves.
- Not on the phone: the form is the way to reach us.
