Prices in Dartford
For Dartford, expect roughly £4,195 to £12,745 for 3–5 rooms, VAT included, adjusted for typical South East England rates. South East England is one of the dearer parts of the UK for trades, which shows in the range. Longer or hidden pipe runs, high-level brackets and electrical upgrades are the usual reasons a quote lands at the top of the range. As an example, the Bungalow or house option (four rooms on one outdoor unit) would typically be £6,045–£9,695 here.

Prices are shown before any Boiler Upgrade Scheme grant. The £2,500 air-to-air grant applies only to eligible homes in England and Wales, using an MCS-certified heat pump installed by an MCS-certified installer, who applies for the grant and deducts it from the price. We confirm eligibility, and which installer applies, before you commit.
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.
If your home in Dartford is replacing fossil fuel or electric heating, and no gas, oil or LPG boiler stays in use, an MCS-certified air-to-air heat pump may qualify for the £2,500 Boiler Upgrade Scheme grant, which the MCS-certified installer claims and deducts from the price.
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 Dartford 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.
