Heat load surveys and system design in Barnstaple
Every Barnstaple quote starts with a room-by-room survey rather than a guess from floor area. In the South West, a system that heats well through damp winters is often as valuable as summer cooling.
No two rooms in Barnstaple gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. Our Devon coverage takes in Barnstaple, about 49 miles from Plymouth. Postcode districts we cover here include EX31.
Prices in Barnstaple
For Barnstaple, expect roughly £395 to £1,250 for a standalone design pack, VAT included, adjusted for typical South West England rates. 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.

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
We book surveys in Barnstaple at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. 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.
