Air conditioning for flats and apartments in Worthing
In the South East, loft rooms and glazed extensions can climb well above the outside temperature on a sunny afternoon. In Worthing apartment blocks, the freeholder's consent is usually the first thing to sort out.
Balcony-mounted outdoor units are often the neatest solution for flats in Worthing. Worthing sits around 22 miles from Crawley, inside our West Sussex area. Homes in BN11 are all within our coverage.
Prices in Worthing
Air conditioning for flats and apartments in Worthing typically comes in at £1,645–£7,245 per flat, one room to the whole flat including VAT, based on South East England rates. That is above the UK middle, mainly because labour and access cost more in South East England. 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 (twin multi-split for living room and main bedroom) would typically be £3,245–£4,795 here.
Single room
One wall unit with a balcony outdoor unit.
Two rooms
Twin multi-split for living room and main bedroom.
Whole flat
Three or four rooms on one outdoor unit, concealed routes.
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
Leaseholders in Worthing usually need the freeholder's consent for anything fixed outside, and blocks of flats often need planning permission for outdoor units. 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
At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote. On a survey in Worthing 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.
