Air conditioning for extensions and kitchen-diners across Lancashire
An extension in Preston with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. For a kitchen-diner in Preston, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Milder summers in the North West mean designing for winter comfort as much as for a heatwave.
Prices in Lancashire
Budget around £1,395–£4,245 per space including VAT for air conditioning for extensions and kitchen-diners in and around Lancashire. That sits a little below the UK middle, reflecting typical North West England labour rates. Quotes move with the length of the pipe run, where the outdoor unit can sit and how much electrical work the job needs. As an example, the Large single option (one 5–7 kW unit for a large glazed space) would typically be £1,945–£2,695 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
For most houses in Lancashire, the outdoor unit is permitted development if it passes the MCS 020(a) noise check (37 dB(A) or less at the nearest neighbouring window) and stays within the size and number limits. We run that check on survey.
The survey
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. At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote.
