Ducted air conditioning in Richmond
For a renovation in Richmond, the best time to plan ducted cooling is before the plasterers arrive. 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.
In an older house in Richmond, the loft and any existing bulkheads decide whether a ducted layout will work. Richmond sits around 8 miles from central London, inside our London area. Homes in TW9 are all within our coverage.
Prices in Richmond
Budget around £7,195–£19,745 per system including VAT for ducted air conditioning in and around Richmond. That is above the UK middle, mainly because labour and access cost more in London. Quotes move with the length of the pipe run, where the outdoor unit can sit and how much electrical work the job needs. As an example, the Zoned option (motorised dampers or two units for separate floors or room groups) would typically be £9,845–£14,445 here.

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 free survey is where the real price is set: room measurements, pipe and drain routes, electrical checks and the outdoor unit position, all written into your quote.
