Heat load surveys and system design in Gosport
For self-builds and extensions in Gosport, a standalone design pack can go straight to your builder. Summers in the South East are among the warmest in the country, so cooling often comes first, with efficient winter heating as a bonus.
Every Gosport quote starts with a room-by-room survey rather than a guess from floor area. Gosport sits around 14 miles from Southampton, inside our Hampshire area. Coverage includes PO12.
Prices in Gosport
For Gosport, expect roughly £495 to £1,495 for a standalone design pack, VAT included, adjusted for typical South East England rates. That is above the UK middle, mainly because labour and access cost more in South East England. A standalone design pack is priced on the size of the home, the number of rooms and how much drawing work your builder or architect needs. Typical Design pack work (drawings and schedules for one home) lands around £495–£945 in this area.

Planning and permissions

The survey
We book surveys in Gosport at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. 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.
