Air conditioning for extensions and kitchen-diners in Wallasey
For a kitchen-diner in Wallasey, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. In the North West, heating efficiency is often the main benefit, with summer cooling a welcome bonus.
An extension in Wallasey with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. Wallasey sits around 4 miles from Liverpool, inside our Merseyside area. That includes the CH44 and CH45 postcode districts.

Labour rates in North West England keep this slightly under the national middle.

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.
