Garden room and home office air conditioning in Caernarfon
Garden offices used every day in Caernarfon need cooling in summer and efficient heat in winter. Exposed coastal sites in North Wales call for outdoor units placed out of the wind and salt spray where possible.
We check the armoured supply cable on every Caernarfon garden room before quoting. We cover Caernarfon as part of Gwynedd, roughly 8 miles from Bangor, Gwynedd. Coverage includes LL55.

Garden room and home office air conditioning in Caernarfon typically comes in at £1,345–£2,945 per system including VAT, based on North Wales rates. That sits a little below the UK middle, reflecting typical North Wales labour rates.

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 Caernarfon 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
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. Surveys in Caernarfon cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
