Heat load surveys and system design in Lowestoft
No two rooms in Lowestoft gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. Long sunny spells in the East of England put conservatories and top-floor rooms under real pressure.
For self-builds and extensions in Lowestoft, a standalone design pack can go straight to your builder. Lowestoft is about 38 miles from Ipswich and falls within our Suffolk coverage. We cover NR32 and the streets around them.

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