Heat load surveys and system design in Westhoughton
Milder summers in the North West mean designing for winter comfort as much as for a heatwave. No two rooms in Westhoughton gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing.
For self-builds and extensions in Westhoughton, a standalone design pack can go straight to your builder. Westhoughton is about 13 miles from Manchester and falls within our Greater Manchester coverage. Postcode districts we cover here include BL5.

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