Heat load surveys and system design in Calne
No two rooms in Calne gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. Damp South West winters make the dehumidifying side of a heat pump almost as useful as its cooling.
For self-builds and extensions in Calne, a standalone design pack can go straight to your builder. Our Wiltshire coverage takes in Calne, about 13 miles from Swindon. Coverage includes SN11.

Planning and permissions
For most houses in Calne, the outdoor unit is permitted development if it passes the MCS 020(a) noise check (37 dB(A) or less at the nearest neighbouring window) and stays within the size and number limits. We run that check on survey.
The survey
We book surveys in Calne at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. On a survey in Calne the engineer looks at room size, glazing, the route for pipes and drains, the electrics and where the outdoor unit can sit quietly, then the written quote follows.
