Heat load surveys and system design in Canterbury
Summers in the South East are among the warmest in the country, so cooling often comes first, with efficient winter heating as a bonus. For self-builds and extensions in Canterbury, a standalone design pack can go straight to your builder.
No two rooms in Canterbury gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. We cover Canterbury as part of Kent, roughly 24 miles from Maidstone. We cover CT1 and the streets around them.
Prices in Canterbury
Budget around £495–£1,495 for a standalone design pack including VAT for heat load surveys and system design in and around Canterbury. That is above the UK middle, mainly because labour and access cost more in South East England. The design pack price depends mainly on the number of rooms and whether full drawings and equipment schedules are needed. Typical Design pack work (drawings and schedules for one home) lands around £495–£945 in this area.

Planning and permissions
For most houses in Canterbury, 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
The free survey is where the real price is set: room measurements, pipe and drain routes, electrical checks and the outdoor unit position, all written into your quote. Surveys in Canterbury cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
