Wandsworth is one of the easier London boroughs to install solar in — much of SW17 and SW18 is inter-war suburban housing with concrete-tile roofs and clear south or south-west aspects. Conservation areas are limited to small pockets around Wandsworth Common. Indicative 4 kWp price: £6,200–£7,800.
What drives the price in Wandsworth
Concrete-tile roofs (Marley Plain, Redland Renown) are standard — fast install, no special fixings needed.
Off-street parking is more common than in inner London — scaffolding day rates are typically £100–£150 lower.
Loft conversions in SW18 sometimes block panel placement — check if a Velux row reduces usable roof.
Frequently asked questions
Is solar cheaper to install in Wandsworth than central London?
Yes, typically £400–£800 less for the same system. Lower scaffolding costs, more off-street parking, and standard concrete-tile roofs all reduce labour time.
