Air conditioning for flats and apartments in Portsmouth
In the South East, loft rooms and glazed extensions can climb well above the outside temperature on a sunny afternoon. Newer blocks in Portsmouth with balconies are often the simplest flats to fit.
Balcony-mounted outdoor units are often the neatest solution for flats in Portsmouth. Portsmouth lies roughly 15 miles from Southampton, and we cover it as part of Hampshire. Postcode districts we cover here include PO5.
Prices in Portsmouth
In South East England, our guide range for air conditioning for flats and apartments is £1,645–£7,245 per flat, one room to the whole flat, including VAT. 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. On our South East England figures, the Two rooms option (twin multi-split for living room and main bedroom) is about £3,245–£4,795.
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
Flats need more care: get your freeholder's written consent first, and expect the planning rules for a block of flats in Portsmouth 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 Portsmouth 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. We book surveys in Portsmouth at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
