Air conditioning for extensions and kitchen-diners in Holyhead
Exposed coastal sites in North Wales call for outdoor units placed out of the wind and salt spray where possible. In Holyhead, a side wall of a single-storey extension is usually the neatest place for the indoor unit.
For a kitchen-diner in Holyhead, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Holyhead is about 21 miles from Bangor, Gwynedd and falls within our Gwynedd coverage. Homes in LL65 are all within our coverage.
Prices in Holyhead
Air conditioning for extensions and kitchen-diners in Holyhead typically comes in at £1,345–£4,195 per space including VAT, based on North Wales rates. That sits a little below the UK middle, reflecting typical North Wales labour rates. 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. On our North Wales figures, the Large single option (one 5–7 kW unit for a large glazed space) is about £1,945–£2,695.
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

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 Holyhead 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.
