Air conditioning for flats and apartments across East Sussex
Newer blocks in Brighton with balconies are often the simplest flats to fit. Balcony-mounted outdoor units are often the neatest solution for flats in Brighton. The South East sees some of the UK's warmest summer days, and south-facing rooms and conservatories feel it first.

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%.
Consent and planning for flats
Flats need more care: get your freeholder's written consent first, and expect the planning rules for a block of flats in East Sussex to be stricter than for a house. In England, permitted development allows one outdoor unit of up to 0.6 m³ on a block of flats; anything more needs planning permission.
The survey
A survey in East Sussex 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. On a survey in East Sussex 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.
