Heat load surveys and system design in Seaford
Every Seaford quote starts with a room-by-room survey rather than a guess from floor area. Hot spells reach the South East early, which makes spring the easiest time to arrange an installation.
No two rooms in Seaford gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. Seaford is about 11 miles from Brighton and falls within our East Sussex coverage. We cover BN25 and the streets around them.
Prices in Seaford
Guide prices around Seaford run from £495 to £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. 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
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. 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.
