Bedroom and loft air conditioning across London
For bedrooms in Westminster, we place the outdoor unit at the back of the house, away from neighbours' windows. Loft conversions and top-floor bedrooms in Westminster gain heat through the roof all day and give it back at night. 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.
Prices in London
Budget around £1,595–£3,895 per room including VAT for bedroom and loft air conditioning in and around London. That is above the UK middle, mainly because labour and access cost more in London. What moves a quote in London up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed. 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.
Essential
2–2.5 kW unit for a small bedroom with a short pipe run.
Popular
Low-noise unit with Wi-Fi for a loft room or main bedroom.
Premium
Very quiet model, concealed pipework or a flat-roof stand.
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
For most houses in London, the outdoor unit is permitted development if it passes the MCS 020(a) noise check (37 dB(A) or less at the nearest neighbouring window) and stays within the size and number limits. We run that check on survey.
The survey
Surveys in London cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare. A survey in London usually takes one to two hours. We measure the rooms, check the walls and the consumer unit, agree the outdoor unit position with you and photograph the pipe routes.
