Real, typical UK installed-price ranges by system size — so you know roughly what to expect before you even book a survey. Every home is different, so treat these as a starting point, not a quote.
Qualifying residential solar panel and battery installations currently benefit from 0% VAT (until 31 March 2027) — these figures are what you'd actually pay, not a pre-VAT list price.
Based on published UK industry cost data for 2026. Your exact price depends on your roof, panel choice, and how straightforward access is.
| System size | Typical home | Typical installed cost | Typical annual saving |
|---|---|---|---|
| ~2.1 kWp | 1–2 bedroom home | £4,000 – £4,700 | £270 – £580/yr |
| ~3.5 kWp | 3 bedroom home | £7,000 – £7,900 | around £450/yr |
| ~4.9 kWp | 4+ bedroom home | around £9,800 | around £640/yr |
Most UK households see payback within roughly 9–15 years, with panels continuing to generate for a decade or more after that.
Price depends heavily on brand, capacity, and whether it's fitted alongside new solar panels or retrofitted to an existing system.
| Battery size | Typical installed cost |
|---|---|
| Small (~5 kWh) | £4,000 – £5,500 |
| Medium (~8–10 kWh) | £5,500 – £7,000 |
| Large / premium (13+ kWh) | £7,000 – £8,000+ |
| Solar + battery combined | £10,000 – £14,000+ |
