Heat load surveys and system design in Exeter
No two rooms in Exeter gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. Coastal breezes help, but inland South West towns and glazed rooms still see uncomfortable peaks.

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