Heat load surveys and system design in Chichester
The South East sees some of the UK's warmest summer days, and south-facing rooms and conservatories feel it first. For self-builds and extensions in Chichester, a standalone design pack can go straight to your builder.
No two rooms in Chichester gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. We cover Chichester as part of West Sussex, roughly 32 miles from Crawley. Coverage includes PO19.
Prices in Chichester
Heat load surveys and system design in Chichester typically come in at £495–£1,495 for a standalone design pack including VAT, based on South East England rates. Prices here sit above the national middle, reflecting South East England labour rates and parking and access costs.

Planning and permissions
For most houses in Chichester, 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 Chichester 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 Chichester cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
