Heat load surveys and system design in Reigate
No two rooms in Reigate gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. Hot spells reach the South East early, which makes spring the easiest time to arrange an installation.
For self-builds and extensions in Reigate, a standalone design pack can go straight to your builder. Reigate is about 16 miles from Woking and falls within our Surrey coverage. That includes the RH2 postcode district.
Prices in Reigate
In South East England, our guide range for heat load surveys and system design is £495–£1,495 for a standalone design pack, including VAT. That is above the UK middle, mainly because labour and access cost more in South East England. 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 £495–£945 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
We book surveys in Reigate at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. On a survey in Reigate 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.
