Wall-mounted air conditioning in Richmond
In a semi or terrace in Richmond, the indoor unit often goes on a back bedroom wall with the outdoor unit on a bracket below. Many London homes are flats or tall terraces, where heat rises to the top floor and the bedrooms bear the brunt of a hot spell.
A single wall-mounted unit is often all a bedroom or sunny living room in Richmond needs. Richmond sits around 8 miles from central London, inside our London area. Homes in TW9 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
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.
