Air conditioning for extensions and kitchen-diners in Dover
The South East sees some of the UK's warmest summer days, and south-facing rooms and conservatories feel it first. In Dover, a side wall of a single-storey extension is usually the neatest place for the indoor unit.
An extension in Dover with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. Dover is about 36 miles from Maidstone and falls within our Kent coverage. Homes in CT16 are all within our coverage.
Prices in Dover
In South East England, our guide range for air conditioning for extensions and kitchen-diners is £1,745–£5,445 per space, 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 Large single option (one 5–7 kW unit for a large glazed space) is about £2,495–£3,495.
Single unit
One 3.5–5 kW unit for a medium extension.
Large single
One 5–7 kW unit for a large glazed space.
Twin units
Two indoor units on a multi-split for long or L-shaped spaces.
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
England's rules let most houses fit an outdoor unit without a planning application, as long as the size, number and MCS 020(a) noise conditions are met. Flats, listed buildings and roof-mounted units are treated differently.
The survey
Surveys in Dover cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare. On a survey in Dover 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.
