Heat load surveys and system design in Thetford
For self-builds and extensions in Thetford, a standalone design pack can go straight to your builder. The East of England is one of the sunniest and driest parts of the UK, which makes glazed rooms and lofts hard to keep cool.
Every Thetford quote starts with a room-by-room survey rather than a guess from floor area. Thetford sits around 27 miles from Norwich, inside our Norfolk area. Coverage includes IP24.

Planning and permissions
England's rules let most houses fit an outdoor unit without a planning application, as long as the size, number and MCS 020(a) noise conditions are met. Flats, listed buildings and roof-mounted units are treated differently.
The survey
Surveys in Thetford cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare. 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.
