Air conditioning for extensions and kitchen-diners in Formby
In Formby, a side wall of a single-storey extension is usually the neatest place for the indoor unit. Damp North West weather makes the dehumidifying mode of a modern split system genuinely useful for much of the year.
For a kitchen-diner in Formby, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Formby is about 11 miles from Liverpool and falls within our Merseyside coverage. That includes the L37 postcode district.

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
In England, most houses can have an outdoor unit under permitted development if it is no larger than 1.5 m³, meets the MCS 020(a) noise limit of 37 dB(A) at the nearest neighbour's window, and there are no more than two on a detached house or one on other houses. Listed buildings need consent.
The survey
A survey in Formby 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. Surveys in Formby cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
