Home Extension Costs in Reigate: 2026 Single, Double & Wrap-Around Prices

Home Extension Costs in Reigate

Reigate's mix of Victorian, Edwardian, and inter-war detached and semi-detached homes makes it one of the strongest extension markets in Surrey. Here's what to budget in 2026.

Cost by Extension Type

Single-storey rear extension — £30,000–£70,000. Most popular type in Reigate. Typical 3m x 5m kitchen-diner extension.

Side return extension — £25,000–£55,000. Common on Reigate Victorian terraces. Adds usable kitchen width.

Double-storey rear extension — £55,000–£120,000. Adds a bedroom + bathroom above the kitchen extension.

Wrap-around extension — £80,000–£160,000. Combines side return and rear. Maximum impact.

Two-storey side extension — £65,000–£130,000. Common on Reigate semis to add a downstairs room and bedroom above.

What's Driving Reigate Extension Costs in 2026

Local labour rates — Reigate sits in a high-demand commuter belt, pushing trade rates above national average

Conservation area requirements — large parts of central Reigate require natural materials (brick to match, slate roofing)

Party wall surveyors — almost every Reigate terrace and semi extension triggers a Party Wall Agreement (£800–£2,000)

Foundation depth — Reigate's clay subsoil often requires deeper foundations than the standard 1m

Reigate Planning Considerations

Conservation areas (parts of Reigate town centre, Reigate Heath): full planning permission usually required, even for smaller rear extensions

Permitted development: most single-storey rear extensions outside conservation areas don't need planning, up to 6m (semi) or 8m (detached) under Larger Home Extension prior notification
