Heat load surveys and system design in Rawtenstall
For self-builds and extensions in Rawtenstall, a standalone design pack can go straight to your builder. Milder summers in the North West mean designing for winter comfort as much as for a heatwave.
Every Rawtenstall quote starts with a room-by-room survey rather than a guess from floor area. We cover Rawtenstall as part of Lancashire, roughly 18 miles from Preston. We cover BB4 and the streets around them.

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
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 Rawtenstall cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
