Heat load surveys and system design in Bath
South West summers are milder on the coast, but sheltered towns and south-facing rooms still overheat, and efficient winter heating matters just as much. For self-builds and extensions in Bath, a standalone design pack can go straight to your builder.
No two rooms in Bath gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. Bath is about 41 miles from Taunton and falls within our Somerset coverage. Postcode districts we cover here include BA1.

Planning and permissions
England's rules let most houses fit an outdoor unit without a planning application, as long as the size, number and MCS 020(a) noise conditions are met. Flats, listed buildings and roof-mounted units are treated differently.
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. A survey in Bath 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.
