Heat load surveys and system design in Preston
North West summers are cooler, so many systems here earn their keep as efficient heaters, with cooling for the warmest weeks. For self-builds and extensions in Preston, a standalone design pack can go straight to your builder.
Every Preston quote starts with a room-by-room survey rather than a guess from floor area. We cover Preston and the rest of Lancashire, including Burnley and Blackburn. Homes in PR0, PR1 and PR11 are all within our coverage.
Prices in Preston
Our North West England guide price for heat load surveys and system design is £375–£1,195 for a standalone design pack, VAT included. It is a touch below the UK middle, as trade rates in North West England tend to be. The design pack price depends mainly on the number of rooms and whether full drawings and equipment schedules are needed. Typical Design pack work (drawings and schedules for one home) lands around £375–£745 in this area.

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
A survey in Preston 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. 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.
