Heat load surveys and system design in Brentwood
For self-builds and extensions in Brentwood, a standalone design pack can go straight to your builder. Bright summers in the East of England mean solar gain through glass is usually the biggest load to design for.
Every Brentwood quote starts with a room-by-room survey rather than a guess from floor area. Brentwood sits around 18 miles from Southend-on-Sea, inside our Essex area. Homes in CM14 are all within our coverage.

Planning and permissions
For most houses in Brentwood, 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
A survey in Brentwood 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. On a survey in Brentwood the engineer looks at room size, glazing, the route for pipes and drains, the electrics and where the outdoor unit can sit quietly, then the written quote follows.
