Bedroom and loft air conditioning in Richmond
London's dense streets hold heat overnight, so top-floor flats and loft rooms often stay warm long after sunset. For bedrooms in Richmond, we place the outdoor unit at the back of the house, away from neighbours' windows.
Loft conversions and top-floor bedrooms in Richmond gain heat through the roof all day and give it back at night. We cover Richmond as part of London, roughly 8 miles from central London. We cover TW9 and the streets around them.
Prices in Richmond
In London, our guide range for bedroom and loft air conditioning is £1,595–£3,895 per room, including VAT. London is one of the dearer parts of the UK for trades, which shows in the range. Longer or hidden pipe runs, high-level brackets and electrical upgrades are the usual reasons a quote lands at the top of the range. As an example, the Popular option (low-noise unit with Wi-Fi for a loft room or main bedroom) would typically be £2,045–£2,895 here.

2–2.5 kW unit for a small bedroom with a short pipe run.

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
Since 29 May 2025, England's permitted development rules allow larger outdoor units (up to 1.5 m³) and no longer require a 1 m gap to the boundary, provided the MCS 020(a) noise check is met. Listed buildings and pitched-roof installs still need permission.
The survey
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. We book surveys in Richmond at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
