Heat load surveys and system design in Stanley
Every Stanley quote starts with a room-by-room survey rather than a guess from floor area. In the North East, sizing for winter heating and then checking summer cooling usually gives the right system.
For self-builds and extensions in Stanley, a standalone design pack can go straight to your builder. Stanley is about 8 miles from Durham and falls within our County Durham coverage. Postcode districts we cover here include DH9.

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. The free survey is where the real price is set: room measurements, pipe and drain routes, electrical checks and the outdoor unit position, all written into your quote.
