Heat load surveys and system design in Gillingham
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 Gillingham, a standalone design pack can go straight to your builder.
Every Gillingham quote starts with a room-by-room survey rather than a guess from floor area. Gillingham lies roughly 9 miles from Maidstone, and we cover it as part of Kent. Coverage includes ME7.
Prices in Gillingham
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. The design pack price depends mainly on the number of rooms and whether full drawings and equipment schedules are needed. As an example, the Design pack option (drawings and schedules for one home) would typically be £495–£945 here.

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