Air conditioning in Crayford
Think of it as diagnose, treat and sign off: the survey diagnoses what the rooms need, the installation is the treatment and commissioning is the sign-off. The sign-off includes testing every mode, showing you the controls and handing over the F-Gas records. Whether you call it air con, air conditioning or an air-to-air heat pump, in Crayford it means the same thing to us: the right unit in the right place, fitted and commissioned properly.
Most installations here are a wall-mounted indoor unit, a short pipe run through the wall and an outdoor unit on the back or side of the property, with the drain run planned so it never drips where it shouldn’t.
Around Crayford, older cottages and newer houses can be very different to work on. Thick walls, low ceilings and beams need care with pipe routes, and if the home is listed, consent comes before any work.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we set them out on your quote. Each brand sets its own conditions, and we’re happy to talk you through them.

Your questions about air conditioning in Crayford
Is air conditioning in Crayford permitted development?
There’s no single answer: the building and the outdoor unit position decide it. Around 15 listed entries sit within 0.5 miles of central Crayford. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and isn’t used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof isn’t allowed under those rules. If there’s any doubt, we ask Bexley council, which is usually the planning authority for Crayford.
Is Crayford within the area you cover?
Yes. Crayford is within the area we cover across London and the South East. Send a few details and pictures, and we reply the same working day.
What does it cost to install air conditioning?
Typically £1,200–£2,200 + VAT for a single-room split, depending on the room, the access and the pipe route. Where you sit in the range depends on pipe length, access, electrics and the model, while commercial systems are priced after a survey.
Do you look at the job first?
Yes, always. We diagnose before we treat: the survey tells us what the job needs and how to do it, and the quote is based on that.
Will you make a mess?
We put dust sheets over floors and furniture near the work first, and we tidy up as we go. Before we leave, we clear up and run through the work with you.
How long does it take to fit air conditioning?
A single-room system is typically fitted in a day. Multi-split, ducted and cassette systems take longer, and we tell you how long on the quote.
When will I hear back?
We reply to enquiries the same working day. For a breakdown that can’t wait, call our 24/7 emergency line.
Looking after your system
Looking after the system is mostly common sense. Our tips:
- File the paperwork with the manual
- Let filters dry fully before you put them back
- Keep the outdoor unit clear of leaves, plants and clutter
We show you how to take the filters out and clean them. Clean them every few weeks when the system is in heavy use, or as the manual recommends, and keep the outdoor unit clear of leaves and clutter.
Book an annual service. A service cleans what you cannot reach and picks up faults before they stop the system and keeps the warranty paperwork right where servicing is a condition.
Air conditioning in Crayford: the local picture
About 42% of homes in Crayford and the neighbourhoods around it were built between the wars, according to Valuation Office Agency council tax records. Homes of that age typically have cavity or solid brick walls, and we check which before planning the pipe route.
Hall Place and Gardens, about 0.9 miles west, is one of the historic houses nearby, and if your own home is listed, consent comes before any air conditioning is fixed to it.

Local landmarks in Crayford

There’s a railway station in Crayford itself: Crayford station. Nearby you’ll also find Bexley Museum (0.9 miles west) and West Hill Hospital (1.3 miles east). Not far away are Wansunt Pit.
Do you need air conditioning in Crayford?
Some people come to us for heating rather than cooling. Old direct electric heaters turn electricity straight into heat, while a heat pump moves heat in from the outside air, which means more heat out than electricity in. That is how most modern split systems work.
The things we’re asked about most include:
- A loft room or top floor that bakes in summer
- Commercial rooms that are too warm for staff
- Fans and portables that don’t keep up
Close to Crayford station? A small study or box room used for work can normally be cooled with a single indoor unit.

Different systems, different jobs
Pipework and condensate drains
Between the units run the refrigerant pipes, the control cable and the condensate drain. We agree the route with you before we drill, and keep it as short and neat as the building allows.
Offices, shops and commercial rooms
Systems over 12 kW of effective rated output bring extra duties for the building, including a TM44 inspection by an accredited energy assessor at least every 5 years. We can arrange the inspection and get the system ready for it.

How the visit works
There’s very little for you to do on the day. Someone needs to let us in and show us the units, or where they’re going, and we take it from there. Before we leave, the area is tidied and we explain what we’ve done. Seeing the property in photos first helps us plan the trip to Crayford.
- First the diagnosis: a survey of the rooms, the walls, the outside and the electrics.
- Next, a recommendation for each room and a fixed price.
- Then the work: units up, pipes and drain run, and a new circuit where necessary.
- Testing: the circuit is pressure tested and evacuated before the refrigerant is released.
- Finally, the clean bill of health: commissioning, the controls explained and your paperwork handed over.
Before we arrive
- Unlock any gate, garage or side passage we need
- Find the manual or the paperwork for the system, if you have it
- Mention any parking restrictions near the property
