Heat load surveys and system design in Braintree
For self-builds and extensions in Braintree, 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.
No two rooms in Braintree gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. We cover Braintree as part of Essex, roughly 25 miles from Southend-on-Sea. Postcode districts we cover here include CM7 and CM77.

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