Air conditioning for extensions and kitchen-diners in Bletchley
In Bletchley, a side wall of a single-storey extension is usually the neatest place for the indoor unit. Hot spells reach the South East early, which makes spring the easiest time to arrange an installation.
For a kitchen-diner in Bletchley, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Bletchley lies roughly 3 miles from Milton Keynes, and we cover it as part of Buckinghamshire. Coverage includes MK3.

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.

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