Heat load surveys and system design in Haywards Heath
Every Haywards Heath quote starts with a room-by-room survey rather than a guess from floor area. Summers in the South East are among the warmest in the country, so cooling often comes first, with efficient winter heating as a bonus.

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
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. On a survey in Haywards Heath 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.
