Heat load surveys and system design in Cheltenham
South West summers are milder on the coast, but sheltered towns and south-facing rooms still overheat, and efficient winter heating matters just as much. Every Cheltenham quote starts with a room-by-room survey rather than a guess from floor area.
For self-builds and extensions in Cheltenham, a standalone design pack can go straight to your builder. We cover Cheltenham as part of Gloucestershire, roughly 7 miles from Gloucester. Postcode districts we cover here include GL50 and GL52.
Prices in Cheltenham
Guide prices around Cheltenham run from £395 to £1,250 for a standalone design pack including VAT. That is broadly in line with national guide prices.

Planning and permissions
Since 29 May 2025, England's permitted development rules allow larger outdoor units (up to 1.5 m³) and no longer require a 1 m gap to the boundary, provided the MCS 020(a) noise check is met. Listed buildings and pitched-roof installs still need permission.
The survey
We book surveys in Cheltenham at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. 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.
