Heat load surveys and system design in Winchester
No two rooms in Winchester 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.
Every Winchester quote starts with a room-by-room survey rather than a guess from floor area. We cover Winchester as part of Hampshire, roughly 12 miles from Southampton. Homes in SO23 and SO25 are all within our coverage.

Prices here sit above the national middle, reflecting South East England labour rates and parking and access costs. Larger homes, more zones and full drawing sets for a builder are what move a design pack towards the upper figure.

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. A survey in Winchester 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.
