Quick answer

Air conditioning in London 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. London has some of the warmest summers in the UK, and the urban heat island means streets and buildings hold their heat after dark. Top-floor flats, loft rooms and bedrooms facing the sun are often still warm at bedtime during hot spells.

Victorian and Edwardian terraces, inter-war semis and suburban flats are common. Loft conversions and rear extensions are popular, and they are often the rooms that overheat first.

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.
