Heat load surveys and system design in Esher
Hot spells reach the South East early, which makes spring the easiest time to arrange an installation. Every Esher quote starts with a room-by-room survey rather than a guess from floor area.
No two rooms in Esher gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. Our Surrey coverage takes in Esher, about 9 miles from Woking. That includes the KT10 postcode district.
Prices in Esher
Heat load surveys and system design in Esher typically come in at £495–£1,495 for a standalone design pack including VAT, based on South East England rates. 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. Typical Design pack work (drawings and schedules for one home) lands around £495–£945 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
We book surveys in Esher at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. 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.
