Air conditioning for extensions and kitchen-diners in Henley-on-Thames
For a kitchen-diner in Henley-on-Thames, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Hot spells reach the South East early, which makes spring the easiest time to arrange an installation.
In Henley-on-Thames, a side wall of a single-storey extension is usually the neatest place for the indoor unit. We cover Henley-on-Thames as part of Oxfordshire, roughly 21 miles from Oxford. Postcode districts we cover here include RG9.

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.
The survey
