Air conditioning for landlords and rental homes in Chelmsford
Low rainfall and long summer days in the East of England make south-facing rooms the first to overheat. Top-floor flats and HMO rooms in Chelmsford can get uncomfortably hot in summer, which tenants notice first.
For Chelmsford landlords, simple wall units with limited remotes are the easiest systems for tenants to live with. Our Essex coverage takes in Chelmsford, about 17 miles from Southend-on-Sea. Coverage includes CM1.
Prices in Chelmsford
Guide prices around Chelmsford run from £1,295 to £6,645 per property, one room to the whole let including VAT. The East of England is one of the dearer parts of the UK for trades, which shows in the range. Concealed pipework, access equipment for high walls and any electrical work are what push prices towards the upper figure. As an example, the Two rooms option (two rooms on separate systems or a twin multi-split) would typically be £2,645–£4,095 here.
Single room
One wall unit for a bedroom or studio.
Two rooms
Two rooms on separate systems or a twin multi-split.
Whole let
Three or four rooms, with a service plan.
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
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.
