Planning ranges
Solar cost snapshot
These are broad UK installed-cost ranges for early planning. A proper quote still needs roof access, electrical checks, equipment specification and MCS paperwork confirmed.
| System | Typical fit | Estimated cost |
|---|---|---|
| 3kW solar | Small roof or low usage | GBP 5,000 to GBP 7,000 |
| 4kW solar | Typical 2 to 3 bedroom home | GBP 6,000 to GBP 8,500 |
| 5kW solar | Higher usage home | GBP 7,500 to GBP 10,500 |
| Battery storage | 5 to 8kWh common domestic range | GBP 4,000 to GBP 7,000 |
Is solar worth it?
Solar is most likely to make sense when the roof is suitable, electricity use is high enough, and the home can use a decent share of its generation. Battery storage can help some homes, but it should earn its place in the quote.

A typical domestic battery can add several thousand pounds. Compare usable capacity, inverter compatibility, warranty, backup features and how much extra solar it helps you use at home.
