Air conditioning for extensions and kitchen-diners in Pwllheli
For a kitchen-diner in Pwllheli, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Mild North Wales summers mean heat pump heating is usually the headline benefit.
In Pwllheli, a side wall of a single-storey extension is usually the neatest place for the indoor unit. Pwllheli is about 26 miles from Bangor, Gwynedd and falls within our Gwynedd coverage. That includes the LL53 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
Wales removed its old 3 m boundary rule on 1 June 2026, so most houses in Pwllheli can now have an outdoor unit under permitted development if it meets the MCS 020a noise condition. Listed buildings still need consent, and conservation areas have extra restrictions.
The survey
On a survey in Pwllheli 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. 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.
