Air conditioning for extensions and kitchen-diners in Plymstock
For a kitchen-diner in Plymstock, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. In the South West, a system that heats well through damp winters is often as valuable as summer cooling.
An extension in Plymstock with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. Plymstock sits around 2 miles from Plymouth, inside our Devon area. Coverage includes PL9.

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
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.
