Costs by property type in the South East
Flats and terraced houses
Smaller roofs usually take a 2–3kWp system, around £4,700 to £8,000 installed in the South East. Terraced homes may need extra scaffold access from the street, and flats need freeholder or management-company consent before panels can go up.
Semi-detached houses
The most common installation: a 3.5–4kWp system on a semi-detached roof costs around £6,300 to £10,400 in the South East. A south-facing slope is ideal, but east-west splits work well too.
Detached houses
Detached homes have the roof space for a 5–6kWp system, typically £8,400 to £13,800 in the South East. Larger systems get a better price per panel, and pairing with a battery captures the surplus a bigger array generates.
