Heat load surveys and system design in Warminster
Every Warminster quote starts with a room-by-room survey rather than a guess from floor area. Damp South West winters make the dehumidifying side of a heat pump almost as useful as its cooling.
No two rooms in Warminster gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. Our Wiltshire coverage takes in Warminster, about 30 miles from Swindon. Coverage includes BA12.

Planning and permissions
In England, most houses can have an outdoor unit under permitted development if it is no larger than 1.5 m³, meets the MCS 020(a) noise limit of 37 dB(A) at the nearest neighbour's window, and there are no more than two on a detached house or one on other houses. Listed buildings need consent.
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.
