Heat load surveys and system design in Southampton
No two rooms in Southampton gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. In the South East, loft rooms and glazed extensions can climb well above the outside temperature on a sunny afternoon.
Every Southampton quote starts with a room-by-room survey rather than a guess from floor area. Southampton is one of the main towns we cover in Hampshire, alongside Portsmouth and Basingstoke. Postcode districts we cover here include SO15.
Prices in Southampton
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. Larger homes, more zones and full drawing sets for a builder are what move a design pack towards the upper figure. On our South East England figures, the Design pack option (drawings and schedules for one home) is about £495–£945.

Planning and permissions
In England, most houses can have an outdoor unit under permitted development if it is no larger than 1.5 m³, meets the MCS 020(a) noise limit of 37 dB(A) at the nearest neighbour's window, and there are no more than two on a detached house or one on other houses. Listed buildings need consent.
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. Surveys in Southampton cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
