Heat load surveys and system design in Wiltshire

Heat load surveys and system design across Wiltshire

No two rooms in Swindon gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. For self-builds and extensions in Swindon, a standalone design pack can go straight to your builder. Coastal breezes help, but inland South West towns and glazed rooms still see uncomfortable peaks.

Prices in Wiltshire

Budget around £395–£1,250 for a standalone design pack including VAT for heat load surveys and system design in and around Wiltshire. It sits near the middle of UK prices. The design pack price depends mainly on the number of rooms and whether full drawings and equipment schedules are needed. As an example, the Design pack option (drawings and schedules for one home) would typically be £395–£795 here.

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

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. A survey in Wiltshire 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.
