Air conditioning for extensions and kitchen-diners in Launceston
For a kitchen-diner in Launceston, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Coastal breezes help, but inland South West towns and glazed rooms still see uncomfortable peaks.
In Launceston, a side wall of a single-storey extension is usually the neatest place for the indoor unit. We cover Launceston as part of Cornwall, roughly 40 miles from Truro. Homes in PL15 are all within our coverage.

Guide prices show VAT at 20%. HMRC treats most fixed air conditioners and air-to-air heat pumps installed in homes as energy-saving materials, zero-rated until 31 March 2027 when we supply and fit them. If your installation qualifies, your quote shows 0% VAT and a lower price. Servicing, repairs, cleaning and controls are charged at 20%.
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
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. On a survey in Launceston 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.
