Air conditioning for landlords and rental homes across East Sussex
Top-floor flats and HMO rooms in Brighton can get uncomfortably hot in summer, which tenants notice first. For Brighton landlords, simple wall units with limited remotes are the easiest systems for tenants to live with. Hot spells reach the South East early, which makes spring the easiest time to arrange an installation.
Prices in East Sussex
In South East England, our guide range for air conditioning for landlords and rental homes is £1,395–£7,245 per property, one room to the whole let, including VAT. That is above the UK middle, mainly because labour and access cost more in South East England. 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 Two rooms option in East Sussex (two rooms on separate systems or a twin multi-split) usually comes to about £2,845–£4,445.
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
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 East Sussex cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare. We book surveys in East Sussex at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
