Heat load surveys and system design across Hampshire
Every Southampton quote starts with a room-by-room survey rather than a guess from floor area. For self-builds and extensions in Southampton, a standalone design pack can go straight to your builder. The South East sees some of the UK's warmest summer days, and south-facing rooms and conservatories feel it first.
Prices in Hampshire
Guide prices around Hampshire run from £495 to £1,495 for a standalone design pack including VAT. Prices here sit above the national middle, reflecting South East England labour rates and parking and access costs.

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
Surveys in Hampshire cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare. 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.
