Commercial air conditioning in Dulwich, done properly
Air conditioning systems with an effective rated output over 12 kW must have a TM44 inspection at least every 5 years. An accredited energy assessor carries it out. We don’t carry out the inspection itself, but we prepare the system and do the work it recommends. If the problem is systems over 12 kW due a TM44 inspection and planning ahead for the HFC phase-down, we can sort it out.
In Dulwich, as anywhere in England, larger systems need F-gas leak checks, and over 12 kW of cooling a TM44 inspection is required. We keep the F-gas records and flag what’s coming up.
Think of the paperwork as the system’s health record: a dated account of the work and the readings we took. If anything goes wrong later, it helps the next engineer and the manufacturer and it’s worth keeping safe.

Business air conditioning in Dulwich
Food Standards Agency records list about 220 cafés, restaurants and staff canteens, about 3 hotels, B&Bs and guest houses and about 55 schools and colleges within roughly a mile and a half of the centre of Dulwich. Many of those sites need air conditioning that is sized for long hours and maintained on a schedule. The Valuation Office Agency’s council tax figures put about 73% of homes in the Dulwich area before 1919, and Census 2021 figures found about 54% of households live in flats. Where shops and offices sit below or beside homes, outdoor plant position and noise need extra care. London commercial jobs normally involve a landlord or managing agent, and plant space is often tight.
Before any plant goes outside a building like Christ's Chapel of God's Gift, its trustees may need planning or heritage advice, and we work with whoever gives it. For a surgery or clinic in the Dulwich Community Hospital area, a planned maintenance contract keeps the system clean and its records up to date.

What affects the cost of commercial air conditioning
Your quote is based on your property. We consider:
- How many units are involved
- Which make and model is being fitted or worked on
- What electrical work the job needs
Putting several jobs into one visit can make for a more efficient booking. Tell us about everything you’d like looked at, and you’ll get one fixed price.
Before you get in touch
A few details help us quote accurately. When you get in touch, it helps to send:
- The fuse board and where it is in the property
- A close-up of the unit’s label showing the model number
- The address and the type of property
Photos are the fastest route to a quote: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Add the address and what you’d like done, and simple jobs can often be priced without a visit.
The process
You do not need to do much on the day. Someone needs to let us in and show us the units, or where they’re going, and the rest is down to us. At the end, we tidy up and run through the work with you. Parking bays, permits and roof or balcony access are the first things we ask about in Dulwich.
- First comes a site survey of the building, its occupancy and the heat it has to deal with.
- We send a fixed-price quote showing the system, the unit positions and how the work will be phased.
- The work is planned around your opening hours, with out-of-hours or phased work where it helps.
- We fit the units, run and test the pipework, connect the condensate and wire in the controls.
- We commission the system, record the refrigerant details and hand over the controls and documents.
Preparing for the visit
- Make sure we can reach the consumer unit or fuse board
- Let us know if the units are on a roof, a high wall or in a locked area
- Find the manual or the paperwork for the system, if you have it

Let and managed properties
Records are where property maintenance often slips. Each visit is written up, plus the F-Gas records where refrigerant is involved, so you can show what was done and when.
Whether it’s one property or many, the approach is the same: diagnosis, a fixed price, access agreed with the people on site and paperwork at the end.
Dulwich questions
Can you fit air conditioning in a London flat in Dulwich?
In many cases, yes, once the lease and the building’s rules are checked. We look at where the outdoor unit could go, such as a balcony, flat roof or rear wall, and write it up for the freeholder or agent.
Will air conditioning in Dulwich need planning permission?
It depends on the property. Central Dulwich sits inside the Dulwich Wood Conservation Area. 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 the local planning authority (for Dulwich, normally Southwark council).
Do you provide ongoing maintenance for businesses?
Yes, maintenance contracts cover servicing, F-gas leak checks and records. We agree the schedule and cost up front.
What kind of air conditioning can you install in a business?
Wall-mounted, cassette, ducted, multi-split and VRF or VRV systems. We recommend the type that suits your space.
Are you F-Gas certified?
F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, plus Checkatrade membership. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.
Do you survey before quoting?
Yes. We always look before we price, either on a site survey or from photos and details for simple jobs. Then you get a fixed-price quote.
Do you work in Dulwich?
Yes. Our area takes in London and the counties of the South East, Dulwich included.
