Prices in Dartford
For Dartford, expect roughly £1,645 to £7,245 per flat, one room to the whole flat, VAT included, adjusted for typical South East England rates.

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 Dartford 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.
