Bedroom and loft air conditioning across East Sussex
Loft conversions and top-floor bedrooms in Brighton gain heat through the roof all day and give it back at night. Top-floor flats in Brighton feel the heat most, because the roof sits right above the bedroom. 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%.
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
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. Surveys in East Sussex cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
