Air conditioning for period and listed homes across Devon
If your Plymouth home is listed or in a conservation area, consent comes first and we provide what the council needs to see. If your home in Plymouth is Victorian, Edwardian or older, a console or concealed system often works better than a high wall unit. South West summers are milder on the coast, but sheltered towns and south-facing rooms still overheat, and efficient winter heating matters just as much.
Prices in Devon
Air conditioning for period and listed homes in Devon typically comes in at £1,650–£7,950 per home, one room upwards including VAT, based on South West England rates. That is broadly in line with national guide prices. What moves a quote in Devon up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed. On our South West England figures, the Concealed option (ducted unit from a loft or void serving one or two rooms) is about £3,450–£5,450.
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 Devon 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. In England, most houses can have an outdoor unit under permitted development if it is no larger than 1.5 m³, meets the MCS 020(a) noise limit of 37 dB(A) at the nearest neighbour's window, and there are no more than two on a detached house or one on other houses. Listed buildings need consent.
The survey
A survey in Devon 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. At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote.
