Heat load surveys and system design in Chelmsford
Every Chelmsford quote starts with a room-by-room survey rather than a guess from floor area. Bright summers in the East of England mean solar gain through glass is usually the biggest load to design for.
For self-builds and extensions in Chelmsford, a standalone design pack can go straight to your builder. Chelmsford lies roughly 17 miles from Southend-on-Sea, and we cover it as part of Essex. Homes in CM1 are all within our coverage.

Planning and permissions
For most houses in Chelmsford, 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
On a survey in Chelmsford 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. We book surveys in Chelmsford at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
