Standard or pre-charged systems
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.

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.
Vetted local installers contact you directly with free quotes for your rooms, so you can compare like for like.
There’s no obligation. Compare the quotes in your own time and go ahead only if one is right for you.
We don’t pass your enquiry to just anyone. Before an installer receives enquiries through us, we check three things.
We confirm public liability insurance is in place before any enquiry is passed on.
Standard systems must be fitted by an F-Gas certified engineer, as UK law requires, and the electrical work done by a qualified electrician.
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.
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.
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.
