Why act early in Childs Hill
Refrigerant rules have changed what new systems use. From 2025, single splits under 3 kg cannot use refrigerants with a GWP over 750, which is why R32, with a GWP of 675, is now common. Older R410A systems have a GWP of 2088. Booking in spring means a home or office in Childs Hill is ready before the first hot week.
Our prices page shows typical ranges, but each job is priced on what it involves. Call for a fixed-price quote, and we’ll talk you through it.

Air conditioning in Childs Hill, done properly
The best installations are planned before a single hole is drilled. We look at each room’s size, glazing, orientation and use, and we agree the unit positions and the route for the pipes, cable and drain, all before the price is fixed. Air conditioning installation in Childs Hill starts with a site survey, followed by a fixed-price quote with the brand, model and every part of the job set out.
Space outside is often tight in Childs Hill, as in much of London, so the outdoor unit may end up on a rear wall, a flat roof or a balcony. We look at noise towards neighbours and windows as well as looks, and we plan the pipe route so it’s as short and tidy as the building allows.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. If that applies to your system, booking the service on time keeps the record straight and each visit is recorded.

Air conditioning around Childs Hill
About 45% of homes in and around Childs Hill were built before 1919, according to the Valuation Office Agency’s council tax figures, and Census 2021 figures found about 66% of households live in flats. Older homes often have solid walls, which take longer to core drill, so we plan pipe routes carefully and keep them as discreet as we can. In flats, the lease and the freeholder normally decide where an outdoor unit can go, and the permitted development rules for flats are tighter. London installs often hinge on outside space, the lease and access to the building.
If you work from home near Cricklewood station, a home office that overheats is one of the easiest rooms to cool. Living close to All Saints? Some older properties in parts like that are protected, and the survey finds out whether yours is.

Honest limits
We’ll always give you a straight diagnosis, so here’s what air conditioning won’t do:
- Building damp that has a structural cause
- A room that can’t take an outdoor unit or pipe route without the landlord’s, management company’s or council’s consent (that consent comes first)
- Stuffy rooms that need fresh air rather than cooling
If in doubt, phone 07833 053749 or drop us a line and we’ll say what we think before booking.

Keeping records across a portfolio is half the battle. Every visit is written up, with F-Gas records wherever refrigerant work is involved, so you can show what was done and when.
Questions from Childs Hill
Can I fit air conditioning in Childs Hill without planning permission?
There’s no single answer: the building and the outdoor unit position decide it. The Redington Frognall Conservation Area is close to the centre of Childs Hill. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and is not used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof is not allowed under those rules. If there’s any doubt, we ask the planning department at Barnet council, typically the authority for Childs Hill.
Can you do air conditioning in Childs Hill?
Yes, Childs Hill is within the area we cover. To start, phone us on 07833 053749 or email us with a few photos.
How quickly will you reply?
You will hear from us the same working day. For a breakdown that cannot wait, call our 24/7 emergency line.
Will skipping a service affect the warranty?
Each manufacturer decides. If servicing is in the terms, missing one could affect a claim and we’ll tell you what your brand asks for.
Does air conditioning work as heating?
Typically, yes. A heat pump moves heat from the outside air into the room, so it gives out more heat than the electricity it uses. To replace your main heating, there are extra conditions, including for the £2,500 Boiler Upgrade Scheme grant for air-to-air heat pumps.
Will you work on another installer’s system?
Yes. We start with a proper look and tell you honestly what we find, including anything about the original installation that needs putting right. Any work is priced before it goes ahead.
Do you protect the property while you work?
We start with protection: sheets over the floor and nearby furniture. Holes and fixings are agreed with you, and we clean up afterwards before we leave.
What we do, step by step
Anything involving refrigerant is handled by F-Gas qualified engineers, as the law requires, while the electrical side is covered by our NICEIC approval. On the day, both are in the same hands. On site, it takes about a day for a single-room system, longer for multi-room and ducted systems. Managed buildings in London often need contractors booked in, and we can deal with the agent for a job in Childs Hill.
- You send photos, or we visit and survey the rooms and outside.
- The system is sized, positions are agreed and the price is fixed.
- We protect the area, then fit both halves of the system.
- Connections are made, checked for leaks and pulled down to a vacuum.
- The system is commissioned, the controls explained and the F-Gas records handed over.
Preparing for the visit
- Let us know where the consumer unit is
- Move furniture away from the wall where we will be working
- Make sure we can reach the outdoor unit, or where it will go

Some jobs can be priced from pictures, while others need a survey. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, you get a fixed price before any work is booked.
