Heat load surveys and system design in Towcester
Every Towcester quote starts with a room-by-room survey rather than a guess from floor area. In the East Midlands, one system that cools in summer and heats efficiently in winter makes good use of the investment.
For self-builds and extensions in Towcester, a standalone design pack can go straight to your builder. Towcester lies roughly 9 miles from Northampton, and we cover it as part of Northamptonshire. Coverage includes NN12.
Prices in Towcester
In the East Midlands, our guide range for heat load surveys and system design is £380–£1,195 for a standalone design pack, including VAT. It is a touch below the UK middle, as trade rates in the East Midlands tend to be. Larger homes, more zones and full drawing sets for a builder are what move a design pack towards the upper figure. On our East Midlands figures, the Design pack option (drawings and schedules for one home) is about £380–£745.

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
We book surveys in Towcester at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. A survey in Towcester 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.
