Installation
Air conditioning installation across London.
Installed properly and priced once. The unit, the installation and the electrical work in a single number, agreed before work starts. Based in Harrow and Stanmore, working right across the capital.

Survey
Survey
A proper look at the room, the wall and the route outside. You get one number covering the unit, the installation and the electrical work, and it is agreed before anything is booked.
Install day
Install day
Floors covered, unit mounted, one clean 71mm core drilled and sleeved hole, insulated pipework in trunking, and the condenser set on Unistrut channel or cantilever arms, the galvanised steel mounts that carry it, with stainless steel fixings. Electrical connection by a qualified electrician.
Commissioning
Commissioning
The system is pressure tested, evacuated and run in both cooling and heating. We check temperatures, the drain and the finish before we call it done.
Handover
Handover
A walkthrough of the controls, the area left clean, and a handover pack with everything worth keeping.
Every install includes
- Up to 3m of pipework
- External trunking, the cover that hides the pipework outside
- Bracket or feet for the outdoor unit
- A gravity drain, so the water runs away without a pump
- Electrical connection by a qualified electrician
- A fused spur on 2.5 and 3.5kW, or its own circuit from your fuse board on 5.0kW and up
- Commissioning, and a handover pack you keep
The prices shown are starting prices for a standard installation. If your job needs longer pipe runs, a condensate pump, access above the first floor, or work on your consumer unit, we price it in your quote, never on the day.
Optional extras
Priced in your quote before you agree, so nothing is added on the day.
| Extra | Price |
|---|---|
| Pipework beyond 3m | £45 per metre |
| Internal boxed trunking | £35 per metre |
| Condensate pump | £160 |
| Removal of an old system | £250 |
| Two visit installation | Plus 10 percent |

What the free survey actually looks at.
The survey exists so the price on the quote is the price on the invoice. It takes about half an hour in a normal house and it works through six things. Nothing is priced until all six have an answer.
The room
Floor area, ceiling height, how much glass there is and which way it faces. A small south facing loft room can need more capacity than a large north facing living room, so the size is picked from the room rather than from the house.
The wall
Where the indoor unit can sit so the air reaches the room properly, which usually means high on a wall with clear space around it, and what is on the other side of that wall outside.
The route
How the pipework and the drain get from one unit to the other, whether that can stay out of sight, and how much of it there is. Three metres is in the price and anything past that is quoted per metre.
The condenser position
Where the outdoor unit can live so it has the air it needs, so the noise is not pointed at your neighbour's window, and so it can be serviced later without a scaffold.
The consumer unit
Whether the board has a spare way and whether the unit needs a fused spur or a dedicated circuit. Anything the board itself needs is priced before the work is booked.
The access
How we reach the condenser position on the day, and whether that makes it a one visit job or a two visit one. We say which before you agree the price.
What happens to your house on the day.
A single room install in a London house is normally one day, start to finish. Floors and furniture in the working area are covered before anything comes out of the van, and the working area is usually smaller than people expect: the wall the indoor unit goes on, the route the pipe takes, and the ground or wall outside where the condenser sits.
There is one hole through the wall, cored at 71mm rather than chased or hammered, and it is sleeved and sealed on both sides. Coring is a wet process on the outside face, so there is dust on the inside face only, and it is vacuumed as it is drilled. The pipework, the drain and the interconnecting cable all run through that one hole.
Outside, the condenser goes on Unistrut channel or on cantilever arms with stainless steel fixings, or on feet at ground level where there is somewhere sensible to stand it. The visible run is in trunking, kept straight and kept to the shortest sensible line. We are the ones who have to look at the photographs afterwards, so it gets done properly.
The system is pressure tested and vacuumed before any refrigerant is released into it, then run in both cooling and heating with the temperatures measured at the grille. If something is not right, it is easier to fix while we are still there, which is the whole point of commissioning before handover rather than after it.
The questions we get asked most.
Where does the outdoor unit go?
Somewhere with air around it and somewhere it can be reached again. On a house that is usually the rear or side wall, or at ground level in the side return. On a flat it is whatever the building allows, which is a conversation with the freeholder rather than with us. It is worth starting that conversation before the survey.
Do I need permission?
It depends on the building and on where the unit goes. Flats, listed buildings and conservation areas are the three worth checking before anything is ordered. We raise it at the survey and tell you what we think needs confirming with the council or the freeholder, but the confirmation itself is yours to get.
How noisy is it?
Modern wall units are quiet indoors, quiet enough that people usually forget they are running. Outdoors there is a fan and a compressor, and how much you hear of it depends on where it is mounted and what is near it. Siting is half the answer, so it is decided at the survey rather than on the day.
Will it heat the room in winter?
Yes. Every unit we fit is a heat pump as well as an air conditioner, so it reverses in winter and heats from the same box on the wall. That is worth knowing before you buy a separate heater for the same room.
