Air conditioning for extensions and kitchen-diners in Rothesay
Here, heat pumps are sized for low winter temperatures and exposed sites. For a kitchen-diner in Rothesay, we place the indoor unit clear of the hob and plan the outdoor unit at the rear.
An extension in Rothesay with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. Rothesay is part of our Argyll and Bute coverage. That includes the PA20 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
In Scotland, planning conditions for outdoor units depend on the property type and location; conservation areas and listed buildings need particular care.
The survey
Where travel is involved, we agree the survey arrangements and any travel cost up front. On the day, the engineer measures the rooms, checks the electrics and agrees the outdoor unit position with you. In Rothesay we often start with photos, room measurements and the make of any existing system, so the survey visit is focused and any travel cost can be quoted in writing first.
