Heat load surveys and system design in Rothwell
The East Midlands gets warm, dry summer spells, and loft conversions and top-floor bedrooms are where the heat builds. For self-builds and extensions in Rothwell, a standalone design pack can go straight to your builder.
Every Rothwell quote starts with a room-by-room survey rather than a guess from floor area. Our Northamptonshire coverage takes in Rothwell, about 12 miles from Northampton. Coverage includes NN14.

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
At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote. A survey in Rothwell 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.
