Multi-split air conditioning across the Scottish Borders
Twin and triple systems suit Galashiels homes where bedrooms sit above the kitchen and one rear wall can take the outdoor unit. In a house in Galashiels with a usable loft, multi-split pipes can often run through it so the front stays clear. Scottish summers are mild, so most systems here are chosen first for efficient heating, with cooling for warm spells.
Prices in the Scottish Borders
For the Scottish Borders, expect roughly £2,245 to £7,145 for 2–4 rooms, VAT included, adjusted for typical Central and Southern Scotland rates. That sits a little below the UK middle, reflecting typical Central and Southern Scotland labour rates. Concealed pipework, access equipment for high walls and any electrical work are what push prices towards the upper figure. On our Central and Southern Scotland figures, the Triple option (three rooms with mixed indoor styles and Wi-Fi control throughout) is about £3,095–£4,995.
Twin
Two rooms on one outdoor unit, wall-mounted indoor units, standard routes.
Triple
Three rooms with mixed indoor styles and Wi-Fi control throughout.
Quad
Four or five rooms, longer concealed runs or a ducted unit in a loft void.
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
Scotland has its own permitted development rules for heat pumps and outdoor units, with stricter treatment of listed buildings and conservation areas. We check the current position for your property with you and, if needed, with the council.
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.
