Air conditioning for period and listed homes in Westminster
If your home in Westminster is Victorian, Edwardian or older, a console or concealed system often works better than a high wall unit. The urban heat island effect means London bedrooms can stay uncomfortably warm on summer nights.
For period homes in Westminster, we look at consoles in place of radiators and ducted units from the loft before anything else. Westminster is part of our London coverage. We cover SW1A, SW1E, SW1H, SW1P, SW1V and SW1W and the streets around them.
Prices in Westminster
In London, our guide range for air conditioning for period and listed homes is £2,195–£10,495 per home, one room upwards, including VAT. 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. For reference, the Concealed option in Westminster (ducted unit from a loft or void serving one or two rooms) usually comes to about £4,545–£7,195.
Console
Low-level console in place of a radiator, rear outdoor unit.
Concealed
Ducted unit from a loft or void serving one or two rooms.
Mixed
Consoles downstairs and ducted upstairs on one system.
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%.
Listed building consent
Listed homes in Westminster need listed building consent from the council before any work, and permitted development does not apply to them. We plan low-impact routes, keep outdoor units out of sight and provide the details a consent application needs. 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
Surveys in Westminster cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare. We book surveys in Westminster at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
