Heat load surveys and system design across Devon
No two rooms in Plymouth gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. Every Plymouth 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.
Prices in Devon
Budget around £395–£1,250 for a standalone design pack including VAT for heat load surveys and system design in and around Devon. That is broadly in line with national guide prices. Larger homes, more zones and full drawing sets for a builder are what move a design pack towards the upper figure. As an example, the Design pack option (drawings and schedules for one home) would typically be £395–£795 here.

Planning and permissions
For most houses in Devon, 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
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 Devon cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
