Where it actually bothers you

Air conditioning for any room.

Bedroom, kitchen, loft, office: we install air conditioning in every room of the house.

01

Sleep through the hot nights

The bedroom that is fine in May and impossible in July. One unit, set once, and the night stops being something to get through.

02

The room everyone ends up in

Open-plan space holds the heat all evening and loses it all winter. The same unit does both — and being able to heat is usually what keeps it under permitted development.

The loft that is unusable by lunchtime

Under a roof, no fan is going to fix it. Most homes are one day on site: dust sheets down in the morning, back to normal that evening.

The homes we work in

Air conditioning for every kind of home.

We have installed air conditioning in most kinds of London property, from Victorian terraces to new-build flats, and each one has its own way of being done. We fit Panasonic, Daikin and Mitsubishi.

Victorian and Edwardian terraces
Most of the homes we work in are these. High ceilings, solid walls and original detail all shape where the pipework goes, and we have done enough of them to know.
Flats and apartments
From mansion blocks to new developments. Where the outdoor unit sits is the thing that varies most, and we have worked with most of the arrangements there are.
Loft conversions
Usually the warmest room in the house, and often the first one people want done. Sloping ceilings and eaves are normal for us.
Period and listed homes
Older buildings ask for more care with the detail, and what is possible varies from address to address. We are used to both.
New builds
Straightforward for the most part. We fit them regularly and they tend to go quickly.
Semi-detached and detached houses
There is usually more room outside to work with, which keeps the pipe runs short and the finishing simple.
Ask about yours

Understand your installation

A clear plan.
Before we begin.

See how the indoor units, the pipework and the outdoor unit fit together — then we design yours around your rooms on the call.

We consider where you sit, work and sleep. The unit position and airflow are planned around the room, with access for cleaning and maintenance.

See it for yourself

Read a real specification

This is the document our fitting team is handed before a job, and it is a real one, for a three-room installation. It shows what each room needs, where the units go and how the pipework runs, with the lengths and rises checked against the manufacturer's limits. It covers the condensate and the electrics, and it says what is included and what is not.

Not sure which one suits your room?

On a free video survey we look at each room with you. Then we tell you which unit we propose, and why. You get a fixed price before we start.

Six years on the equipment. Lifetime guarantee on pipework and insulation.

Figures from each maker's UK specification data. Size, efficiency and noise are for the size you choose; the 3.5 kW model, or the nearest size, is shown first. SEER is for cooling and SCOP for heating; higher is cheaper to run. Noise is the indoor unit on its quietest setting.

The right arrangement

Single-room and multi-room air conditioning.

Wall-mounted split systems for one room, multi-split systems for several, and concealed ducted units where you want nothing on the wall. We recommend the arrangement after assessing your property.

Single-room systems

A dedicated system for one room.

Multi-room systems

Several indoor units can share an outdoor unit, where the layout allows.

On the call we show you which arrangement suits your rooms, and why.

After it is fitted

Lifetime on our pipework.

Six years on the equipment, and the first year's service is on us. After that we do the servicing ourselves, so it stays one phone call for as long as you own it.

Annual service

First year included. We remind you when it is due.

Documented install

What was fitted and where it runs, kept on file.

Same company

Call in year five and we already know your system.

Straight answers

Everything people ask us.

The things people ask before they book. If yours is not here, ask it on the call — you will get the same straight answer.

Ask us directly

The price and the survey

What it costs and how we arrive at the figure.

How much will it cost?

Three things move it: how many rooms, where the outdoor unit can sit, and how far the pipework has to run. The same three bedrooms come to different figures in a Victorian terrace and a new-build flat — so we'd rather tell you what yours comes to than put a number on a page that fits nobody. Tell us where you are and we'll come back today.

Is the price genuinely fixed?

Yes. The figure you agree is the figure you pay. It moves only if you ask for something different from what was quoted.

Your home and permissions

The parts that depend on your building rather than on us.

Do I need planning permission?

Usually not. Since 2025 most domestic systems that both heat and cool fall under permitted development. It does depend on the unit, where it goes and what kind of building you have — so we check yours on the call and tell you exactly where you stand, before you spend anything.

Where will the outdoor unit go?

It needs airflow, room to service it and a sensible pipe route to the indoor units — a rear garden, a side return or a wall position usually works. We look at the space, the neighbouring windows and any restrictions with you on the call, and the position is agreed before anything is ordered.

Will my neighbours be able to object?

We choose the outdoor position, the mounting and the anti-vibration with the boundary and nearby windows in mind, and the noise limit that comes with permitted development is part of what we check for you. You get the figure in writing: the sound level calculated at your boundary and at the nearest neighbouring window, against the limit — so it is a number you can show someone, not a reassurance.

Will it make a mess of my walls?

You see the pipe route and agree what will be visible before anyone starts, and the trunking, boxing and making good are written into your quotation. Nothing about the finish is a surprise.

The equipment

What we fit, and what it will and will not do.

Which brands do you install?

Panasonic, Daikin and Mitsubishi. On the call we explain which suits your rooms and why — the choice follows the room, not what happens to be easiest for us to get hold of.

Can it heat as well as cool?

Most of the systems we fit can do both, and it matters beyond comfort: a heating-capable system is also the one that generally falls under permitted development. The functions of your specific equipment are confirmed in your quotation.

How quiet will it be?

Quieter than most people expect — modern indoor units are designed to disappear into a room. We go through the manufacturer's sound figures for the exact units we are proposing, and where the outdoor unit will sit, so you know what you are getting before you agree to it.

What will it cost to run?

It comes down to how much you use it, your tariff and how well your home holds temperature. On the call we show you the efficiency rating of the system we are proposing and what that means day to day, so you can weigh it up properly.

The installation

The days we are in your home.

How long does it take?

Up to three indoor units is a day on site. Four to six is two days. You get a date when you accept the quotation.

How much disruption is there?

One working day for most homes. Dust sheets go down before anything starts, and the room is left clean — most people are back to normal that evening.

After it is fitted

For as long as you own it, not just the invoice.

What is guaranteed, and for how long?

A lifetime guarantee on pipework and insulation, and six years on the equipment. The first year's service is included, and after that we do the servicing ourselves: one phone call, not a hunt for someone who will take it on.

What happens if something goes wrong?

You call us. Every installation is documented — what was fitted, where the pipework runs, what it is set to — so in year three we already know your system instead of starting from scratch.
