Air conditioning for period and listed homes in Diss
If your home in Diss is Victorian, Edwardian or older, a console or concealed system often works better than a high wall unit. Bright summers in the East of England mean solar gain through glass is usually the biggest load to design for.
If your Diss home is listed or in a conservation area, consent comes first and we provide what the council needs to see. Diss is about 19 miles from Norwich and falls within our Norfolk coverage. Coverage includes IP22.
Prices in Diss

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 Diss 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. For most houses in Diss, 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 Diss cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare. On a survey in Diss the engineer looks at room size, glazing, the route for pipes and drains, the electrics and where the outdoor unit can sit quietly, then the written quote follows.
