Air conditioning for extensions and kitchen-diners in Peckham
In London, heat soaks into brick and concrete during the day and comes back out at night, which is when it is hardest to sleep. An extension in Peckham with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon.
In Peckham, a side wall of a single-storey extension is usually the neatest place for the indoor unit. Peckham is about 3 miles from central London and falls within our London coverage. Coverage includes SE15.

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.
