What solar has cost in the North West
The fairest price check is the government's own. Every year the Department for Energy Security and Net Zero publishes what MCS-certified solar actually cost, split by region and size. In 2025/26 it analysed 22,981 North West installations (DESNZ solar PV cost data, published 28 May 2026).
For systems up to 4 kW, the size band of 60% of home installations that year, the North West average was £2,021 per kW. Larger systems from 4 to 10 kW averaged £1,768 per kW, because scaffolding, the inverter and the visit cost much the same whatever the size. The Energy Saving Trust puts a typical home system at 4.5 kWp for around £7,600 (Energy Saving Trust, updated 1 October 2026).
One date matters: installed solar and batteries carry 0% VAT until 31 March 2027, then 5% (HMRC VAT Notice 708/6). On an £8,000 installation that is £400 from April 2027, by our arithmetic.
