Greater London · Air conditioning installation
Air con installers in Pratt's Bottom
Air conditioning in and around Pratt's Bottom, from a site survey or diagnosis to sign-off and a fixed price agreed before any work starts.
- A system on old refrigerant that’s due for replacement
- Working from home in a room that gets too warm
- Uncertainty over the right type and size of system
How the job changes from property to property
Electrical supply
The fuse board is looked at during the survey, so any extra electrical work is on the quote rather than a surprise on the day. An older board may need extra work and we’ll tell you if yours does.
Pipework and condensate drains
Air conditioning takes moisture out of the air when it cools, which the condensate drain takes away. If gravity won’t do it, a condensate pump is fitted, and we plan that on the survey.
Air conditioning installation in Pratt's Bottom
A new system normally needs a dedicated circuit from the fuse board. Adding a new circuit is notifiable building work under Part P unless it’s done by a registered competent person, and as NICEIC approved contractors we can install and certify it as part of the job. When someone in Pratt's Bottom asks us for air con, the first questions are normally price and who will fit it. We publish typical prices and do the refrigerant work as an F-Gas certified company.
The outdoor unit position is the biggest single decision: we balance airflow, noise, the pipe run and access for future servicing.
London homes in Pratt's Bottom can be short of outside space, so the outdoor unit may end up on a rear wall, a flat roof or a balcony. Neighbours’ windows and noise matter as much as appearance when we choose the position, 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. Where yours does, a regular service with us keeps that side in order, and every service is written up.

Keeping the system healthy
Here’s the after-treatment advice, short and simple:
- Keep the F-Gas records, commissioning details and warranty information together
- Avoid setting it far colder than you need
- Let filters dry fully before you put them back
You get the paperwork that matters: F-Gas records, commissioning details and the manufacturer’s warranty terms. File them together as they’re needed for servicing and any warranty question.
Book an annual service. The engineer cleans the coils and drain, checks the electrics and the refrigerant circuit and catches small problems early, and it keeps any warranty servicing conditions in order.
How it works
Every visit follows the same order: agree the plan on site, put the dust sheets down, carry out the job, test what we’ve done and explain it all to you. The visit itself takes a day or more, depending on the number of rooms, the pipe routes and the access. A note on parking and access helps us plan a visit to Pratt's Bottom.
- First the diagnosis: a survey of the rooms, the walls, the outside and the electrics.
- Then the prescription: the right system and size for each room, on a fixed-price quote.
- The treatment: units fitted, pipework and drain routed, and the electrics installed.
- Before it runs, the pipework is proved tight and put under vacuum.
- The sign-off: commissioning, a walk through the controls, and the F-Gas records and warranty details.
Preparing for the visit
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Tell us about any building rules, permits or sign-in

Questions from Pratt's Bottom
Is Pratt's Bottom in your area for air conditioning?
Yes, Pratt's Bottom is within the area we cover. Just ring us on 07833 053749 with a few details.
Is planning permission needed for air conditioning in Pratt's Bottom?
The answer turns on the property and where the outdoor unit would sit. Around 1 listed entries sit within 0.5 miles of central Pratt's Bottom. Permitted development only covers heat pumps that aren’t used solely for cooling, and not within the grounds of a listed building. Conservation areas add limits on outdoor units facing a road. Where needed, we check with Bromley council, which is usually the planning authority for Pratt's Bottom.
Do you look at the job first?
Yes, every time. Diagnosis comes before treatment: the survey shows what’s needed, where things go and what access we need and the fixed price is built on it.
Will you make a mess?
We put dust sheets over floors and furniture near the work first, and the area is kept tidy throughout. Before we leave, we clear up and run through the work with you.
Can I fit air conditioning or a heat pump myself?
Not the refrigerant work. The F-gas rules require certified companies and qualified engineers for it, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
Do you provide F-Gas records?
Yes, always. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, and repairs and services get a record of the work.
Will skipping a service affect the warranty?
For some brands, yes. Read the manufacturer’s terms, or send us the make and model and we will explain them, and book the service at the interval they recommend.
What affects the quote in Pratt's Bottom
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether we need access equipment for high-level work
- Whether the existing supply is suitable
- The condition of any existing system
Typical ranges are on our prices page, but your price depends on the job in front of us. Call for a fixed-price quote, and we’ll explain what it covers.
Helping us quote
Good photos often save a visit. The most useful are:
- Any error code or flashing light on the display
- The address and the type of property
- A close-up of the unit’s label showing the model number
Photos are enough for some jobs; others need a visit first. 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.

What else we do in Pratt's Bottom
Air conditioning in Pratt's Bottom: local notes
The Valuation Office Agency’s council tax figures date about 45% of homes in and around Pratt's Bottom to the post-war years, 1945 to 1972, and about 76% of households live in detached or semi-detached houses, according to Census 2021 figures. We check the wall construction on homes of that age, as it decides how the pipework goes through. Houses usually have a side or rear wall with room for the outdoor unit, and a multi-split can serve several rooms from one outdoor unit. London installs often hinge on outside space, the lease and access to the building.
