Heat load surveys and system design in Falmouth

Heat load surveys and system design in Falmouth

For self-builds and extensions in Falmouth, a standalone design pack can go straight to your builder. Coastal breezes help, but inland South West towns and glazed rooms still see uncomfortable peaks.

Every Falmouth quote starts with a room-by-room survey rather than a guess from floor area. Our Cornwall coverage takes in Falmouth, about 8 miles from Truro. Coverage includes TR11.

Prices in Falmouth

Guide prices around Falmouth run from £395 to £1,250 for a standalone design pack including VAT. That is broadly in line with national guide prices. The design pack price depends mainly on the number of rooms and whether full drawings and equipment schedules are needed. On our South West England figures, the Design pack option (drawings and schedules for one home) is about £395–£795.

Planning and permissions

Since 29 May 2025, England's permitted development rules allow larger outdoor units (up to 1.5 m³) and no longer require a 1 m gap to the boundary, provided the MCS 020(a) noise check is met. Listed buildings and pitched-roof installs still need permission.

The survey

At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote. Surveys in Falmouth cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
