Heat load surveys and system design in Maidenhead
In the South East, loft rooms and glazed extensions can climb well above the outside temperature on a sunny afternoon. For self-builds and extensions in Maidenhead, a standalone design pack can go straight to your builder.
Every Maidenhead quote starts with a room-by-room survey rather than a guess from floor area. Our Berkshire coverage takes in Maidenhead, about 12 miles from Reading. That includes the SL6 postcode district.
Prices in Maidenhead
Our South East England guide price for heat load surveys and system design is £495–£1,495 for a standalone design pack, VAT included. South East England is one of the dearer parts of the UK for trades, which shows in the range. Larger homes, more zones and full drawing sets for a builder are what move a design pack towards the upper figure. On our South East England figures, the Design pack option (drawings and schedules for one home) is about £495–£945.

Planning and permissions
Since 29 May 2025, England's permitted development rules allow larger outdoor units (up to 1.5 m³) and no longer require a 1 m gap to the boundary, provided the MCS 020(a) noise check is met. Listed buildings and pitched-roof installs still need permission.
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. On a survey in Maidenhead the engineer looks at room size, glazing, the route for pipes and drains, the electrics and where the outdoor unit can sit quietly, then the written quote follows.
