- Roof type and access — complex roofs, tiles that need special fixings and scaffolding add cost
- Panel quality — premium, higher-efficiency panels cost more per kW
- Inverter — hybrid inverters ready for batteries cost more than basic ones
- Battery storage — adding a battery raises the installed price considerably
- VAT relief — solar panels installed in homes qualify for zero-rated VAT
Electrical work prices in the UK are up 6% over five years (ONS Consumer Price Inflation, Services for maintenance and repair, to 2026 August). Five years ago a typical solar pv installation would have cost about £8520 — an estimate from today's guide price and that index, not a recorded price. Source: ONS MM23 D7DO →

How to pay less
- Fit solar panels when scaffolding is already up for roof or render work
- Size the solar PV system to your electricity use rather than filling the whole roof
- Check the solar PV quote shows zero-rated VAT, which applies to solar panels installed in homes
Before you book
- Use an MCS-certified installer so you can claim Smart Export Guarantee payments
- Most roof-mounted solar panels are permitted development, but listed buildings and conservation areas may need consent
- Check the roof is in good condition, as removing panels later for repairs adds cost
- Ask the solar installer for an estimate of yearly generation and savings in writing

Usually not on a house roof, as most installs are permitted development. Flats, listed buildings and conservation areas can be different.
Batteries, EV charger links, roof repairs and bird-proofing are often extra. Ask whether scaffolding is included.
