Heat load surveys and system design across Kent
No two rooms in Maidstone gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. Every Maidstone quote starts with a room-by-room survey rather than a guess from floor area. Hot spells reach the South East early, which makes spring the easiest time to arrange an installation.
Prices in Kent
Our South East England guide price for heat load surveys and system design is £495–£1,495 for a standalone design pack, VAT included. That is above the UK middle, mainly because labour and access cost more in South East England. A standalone design pack is priced on the size of the home, the number of rooms and how much drawing work your builder or architect needs. For reference, the Design pack option in Kent (drawings and schedules for one home) usually comes to about £495–£945.

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