Air conditioning installation in London & surrounding areas

F-Gas certified split-system air conditioning for homes across London and the surrounding areas — supplied, installed and serviced. Cool in summer, efficient heat in winter, with the pipework kept discreet.

A heat pump on the wall, not just a fan

Most people think of air conditioning as a summer purchase. Modern units are heat pumps, which means they run in reverse in winter — moving warmth into the room rather than generating it — and can deliver several times more heat per unit of electricity than a plain electric heater.

That changes the maths. A unit fitted for a hot bedroom in July can also warm a loft conversion, garden room or home office in January, without extending the central heating. Air conditioning or a heat pump? Read the guide.

What we do

Supply, install & servicing

Supply & installation

We supply a unit sized for your room and fit it, or fit one you have already bought. A free survey first, then a quote.

Split systems

A wall-mounted indoor unit linked to an outdoor unit by neat, discreet pipework. Right for bedrooms, living rooms, lofts, offices and garden rooms.

F-Gas certified

Refrigerant is handled by F-Gas certified hands, as it should be. The pipework is pressure-tested and the system properly commissioned before we hand it over.

Servicing & aftercare

Filters, coils and drains need looking after to keep a unit efficient, fresh and reliable. We service air conditioning, and tell you what you can safely do yourself.

Heating as well as cooling

Modern split systems are heat pumps, so they work year round. Ask us to show you the rated input in heating mode, so you can work out a real running cost.

Sized for the room

A unit that is too small for the space struggles. We measure the room and allow for glazing, aspect and how you use it before recommending a size.

F-Gas certified, and why it matters

The refrigerant in air conditioning is an F-gas. It is a powerful greenhouse gas, so the law says it must not be vented. Whoever you choose, check that they hold both the company F-gas certification and the technician's personal qualification.

Step by step

From survey to first cold air

  1. 1

    Free home survey

    We look at the room, where the indoor unit can sensibly go, and where the outdoor unit can be sited with a workable pipe run. You get a quote.

  2. 2

    Unit selection

    We recommend a size and model to suit the room and your budget, and explain the difference in running cost between options. Fit-only is fine if you have already bought a unit.

  3. 3

    Installation

    How long it takes depends on the room, the number of units and the pipe run, and we confirm it at the free survey.

  4. 4

    Commissioning & handover

    System pressure-tested, charged and run in both heating and cooling, and then we sit down and show you how to use the controller, including the settings that keep running costs down.

What is involved in an installation: the full walk-through

Good to know

Air conditioning — your questions

Anything else, just ask. Straight answers, no sales script.

Does air conditioning heat as well as cool?

Yes. Modern split systems are heat pumps, so they run in reverse in winter and warm the room. A heat pump uses less electricity than a plain electric heater for the same amount of heat.

Are you F-Gas certified?

Yes, we are F-Gas certified. Whoever you choose, check that they hold both the company F-gas certification and the technician's personal qualification.

Do you supply the unit or just fit it?

Either. We can supply a unit sized for your room and fit it, or fit one you have already bought. If you have already bought one, send us the model and we will tell you honestly whether it suits the room.

How long does an installation take?

It depends on the number of units, the length of the pipe runs and how easy the access is. We confirm the timing at the free survey.

How often should air conditioning be serviced?

Once a year is the usual advice for a unit that gets regular use, and more often in dusty homes or where it runs heavily. Filters can be cleaned by you in between. Follow your manufacturer's guidance, as some warranties expect regular servicing.

Do I need planning permission?

A domestic wall-mounted unit often falls under permitted development, but it depends on your property. Flats, listed buildings and conservation areas have extra rules, and there are limits on siting and noise. If we think you need to check with the council, we will say so before you order anything.

Is it noisy for me or my neighbours?

Noise varies by model, and manufacturers publish a sound rating for the indoor and the outdoor unit. The outdoor unit makes some noise, which is why siting matters, so we talk through where it will go at the survey.

How much does it cost to run?

It depends on the unit, the room and how you use it, so we will not quote a figure blind. At survey we can show you the rated input for the unit we are proposing, which lets you work out a realistic hourly cost at your own electricity rate.
