Heat load surveys and system design in Gloucester
Coastal breezes help, but inland South West towns and glazed rooms still see uncomfortable peaks. Every Gloucester quote starts with a room-by-room survey rather than a guess from floor area.
For self-builds and extensions in Gloucester, a standalone design pack can go straight to your builder. Gloucester is one of the main towns we cover in Gloucestershire, alongside Cheltenham and Stroud. Postcode districts we cover here include GL1.
Prices in Gloucester
Budget around £395–£1,250 for a standalone design pack including VAT for heat load surveys and system design in and around Gloucester. That is close to the UK middle for this kind of work. 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
A survey in Gloucester usually takes one to two hours. We measure the rooms, check the walls and the consumer unit, agree the outdoor unit position with you and photograph the pipe routes. On a survey in Gloucester 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.
