Air conditioning for period and listed homes in Stevenage
Bright summers in the East of England mean solar gain through glass is usually the biggest load to design for. If your Stevenage home is listed or in a conservation area, consent comes first and we provide what the council needs to see.
If your home in Stevenage is Victorian, Edwardian or older, a console or concealed system often works better than a high wall unit. Stevenage is about 19 miles from Watford and falls within our Hertfordshire coverage. We cover SG1 and the streets around them.
Prices in Stevenage
For Stevenage, expect roughly £1,845 to £8,895 per home, one room upwards, VAT included, adjusted for typical East of England rates. The East of England 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. For reference, the Concealed option in Stevenage (ducted unit from a loft or void serving one or two rooms) usually comes to about £3,845–£6,095.
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
Period homes in Stevenage that are not listed can usually follow the normal rules for outdoor units, but listed buildings always need consent, and conservation areas restrict units on elevations facing a road. 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 Stevenage cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare. A survey in Stevenage 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.
