Quick answer

Air conditioning in Wales is usually a split system that cools, heats and dehumidifies, fitted either as a standard system by an F-Gas certified engineer or as a pre-charged system that needs no F-Gas engineer. Wales has a mild, wet climate, with warmer summers in the south and in towns. A system that heats, cools and dehumidifies is useful through the year.

Stone terraces in the valleys, coastal homes, rural cottages and newer estates are common, with many listed buildings and conservation areas. Wales has its own planning and building rules, which installers will check for your property.

Why use us

Why use Air Conditioning Comparison?

  1. We’re independent.

    We don’t sell air conditioning and we don’t install it. We work for you, matching you only with vetted local installers who cover your area.

  2. Installers quote.

    Vetted local installers contact you directly with free quotes for your rooms, so you can compare like for like.

  3. You decide.

    There’s no obligation. Compare the quotes in your own time and go ahead only if one is right for you.

Trust and safety

What “vetted” means

We don’t pass your enquiry to just anyone. Before an installer receives enquiries through us, we check three things.

  • Relevant insurance

    We confirm public liability insurance is in place before any enquiry is passed on.

  • The right certification

    Standard systems must be fitted by an F-Gas certified engineer, as UK law requires, and the electrical work done by a qualified electrician.

  • Warranty

    Installations must be backed by a written warranty on the work, alongside the manufacturer’s warranty on the equipment, so you’re covered after the fitter leaves.

Air conditioning in Wales: common questions

How much does air conditioning cost in Wales?

It depends on the system, number of rooms, unit sizes, pipe run and electrics. Comparing like-for-like quotes from local installers is the best guide.

Do I need an F-Gas engineer?

For a standard split system, yes. A pre-charged system needs no F-Gas engineer for a typical install, but still needs a qualified electrician.
