New build and renovation air conditioning in Portsmouth
Renovations in Portsmouth are the easiest jobs to make invisible, because the pipework goes in before the plaster. The South East sees some of the UK's warmest summer days, and south-facing rooms and conservatories feel it first.
First-fix pipework in Portsmouth extensions goes in while the joists and studs are open. Our Hampshire coverage takes in Portsmouth, about 15 miles from Southampton. Coverage includes PO5.

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.

We book surveys in Portsmouth at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. 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.
