Air conditioning for extensions and kitchen-diners in Ilford
London's dense streets hold heat overnight, so top-floor flats and loft rooms often stay warm long after sunset. In Ilford, a side wall of a single-storey extension is usually the neatest place for the indoor unit.
An extension in Ilford with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. Ilford sits around 9 miles from central London, inside our London area. Postcode districts we cover here include IG1, IG4 and IG5.
Prices in Ilford
Our London guide price for air conditioning for extensions and kitchen-diners is £1,895–£5,845 per space, VAT included. London is one of the dearer parts of the UK for trades, which shows in the range. The biggest variables are the pipe route, access for the outdoor unit and the state of the consumer unit, all of which the survey settles. As an example, the Large single option (one 5–7 kW unit for a large glazed space) would typically be £2,695–£3,745 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
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.
The survey
We book surveys in Ilford at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. The free survey is where the real price is set: room measurements, pipe and drain routes, electrical checks and the outdoor unit position, all written into your quote.
