Heat load surveys and system design in Lancaster
Milder summers in the North West mean designing for winter comfort as much as for a heatwave. For self-builds and extensions in Lancaster, a standalone design pack can go straight to your builder.
Every Lancaster quote starts with a room-by-room survey rather than a guess from floor area. Lancaster sits around 20 miles from Preston, inside our Lancashire area. Postcode districts we cover here include LA1.

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.
