Heat load surveys and system design in Gravesend
Every Gravesend quote starts with a room-by-room survey rather than a guess from floor area. Hot spells reach the South East early, which makes spring the easiest time to arrange an installation.
For self-builds and extensions in Gravesend, a standalone design pack can go straight to your builder. Our Kent coverage takes in Gravesend, about 14 miles from Maidstone. That includes the DA12 postcode district.

Planning and permissions
For most houses in Gravesend, the outdoor unit is permitted development if it passes the MCS 020(a) noise check (37 dB(A) or less at the nearest neighbouring window) and stays within the size and number limits. We run that check on survey.
The survey
Surveys in Gravesend cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare. 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.
