New build and renovation air conditioning in Kelso
Scottish summers are mild, so most systems here are chosen first for efficient heating, with cooling for warm spells. First-fix pipework in Kelso extensions goes in while the joists and studs are open.
For new Kelso extensions with flat roofs, the outdoor unit position is best agreed against the architect's drawings. Kelso is about 15 miles from Galashiels and falls within our Scottish Borders coverage. Homes in TD5 are all within our coverage.

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%.
Working with your builder
Because the pipework is built into the structure, coordination with your builder matters more than planning here; the outdoor unit follows the same rules as any other installation.
The survey
On a survey in Kelso 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. A survey in Kelso usually takes one to two hours. We measure the rooms, check the walls and the consumer unit, agree the outdoor unit position with you and photograph the pipe routes.
