Air conditioning for extensions and kitchen-diners across Gloucestershire
An extension in Gloucester with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. In Gloucester, a side wall of a single-storey extension is usually the neatest place for the indoor unit. South West summers are milder on the coast, but sheltered towns and south-facing rooms still overheat, and efficient winter heating matters just as much.
Prices in Gloucestershire
Air conditioning for extensions and kitchen-diners in Gloucestershire typically comes in at £1,450–£4,450 per space including VAT, based on South West England rates. That is broadly in line with national guide prices. Concealed pipework, access equipment for high walls and any electrical work are what push prices towards the upper figure. As an example, the Large single option (one 5–7 kW unit for a large glazed space) would typically be £2,050–£2,850 here.
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
On a survey in Gloucestershire 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. A survey in Gloucestershire 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.
