About our AHU cleaning in Dulwich Village
Every supply and extract system relies on the air handling unit at its centre: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, which is why we clean the unit itself, not just the ducts. The work covers dampers and louvres, internal panels and drain trays, and people most often call us about drain trays holding standing water and leaves and litter drawn into the unit.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so ventilation cleaning in Dulwich Village is typically planned out of hours. Parking and loading are agreed with the building in advance.
We have been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

How the job changes from site to site
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe in agreement with the site.
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. We check them, and clean or change them as agreed in the quote, and the housing around them is cleaned too.
What a clean will not put right
Before you book, it helps to know what’s not included:
- Ventilation that was badly designed in the first place
- Damaged coils beyond cleaning
- Breakdowns that need a mechanical engineer
If in doubt, call 0345 646 2711 or use the quote form and we will say what we think.
Parts of the system we cover
- Dampers and louvres
- Filter sections
- Internal panels
- Heating and cooling coils
- Drain trays
- Supply and extract fans
What happens if it’s left?
A light clean now is simpler than a heavy one later. Leave it for years and dirt bakes onto coils and casings, especially where there’s been moisture. A booked night’s work in Dulwich Village costs you no trading time; an unplanned closure does.
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.

Your questions about AHU cleaning in Dulwich Village
Do you clean school ventilation in Dulwich Village in the holidays?
Yes, holiday work suits schools best. The FSA’s register shows about 65 schools and colleges with food registrations within roughly a mile and a half of Dulwich Village. Booking early in the term gives the best choice of holiday dates.
Can you work in Dulwich Village outside opening hours?
Yes, out-of-hours work is a big part of what we do. The work in Dulwich Village can fit around your hours. When you call 0345 646 2711 or use the quote form, mention when the site is quiet.
How much notice should we give?
That depends on the slot you want and the size of the job. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
What information do you need?
Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and the last report help too. Then phone us on 0345 646 2711 or email us.
What does AHU cleaning cost?
Every site is different, so each gets its own fixed quote. To get one, call 0345 646 2711 or email us and tell us about the site and its opening hours.
How long will the unit be out of action?
Expect it to take anything from half a day for one small unit to several shifts for a plant room full of them. Size, layout and how dirty it is decide the rest, and we will confirm the time when we quote.
What do you do with what you remove?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. We don’t leave it behind.
Do you have a 24/7 line?
Yes. There’s a 24/7 emergency line, for problems that can’t wait. Ring any time and tell us what’s happened.
What your team can do, and what needs us
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Keeping the system healthy
Once we’ve finished, these simple steps help:
- Make sure the unit’s access doors open easily
- Report musty smells from the vents right away
- Diary the inspection date recommended in the report
- Report water on the plant room floor
Stick to the filter change schedule, because good filters protect everything downstream. Log every change so it’s easy to see when the next is due.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.
Landlords, agents and facilities managers
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side, and the report can go to both.
We also work for facilities teams across offices, schools and healthcare in Dulwich Village and across Greater London. Work can be phased by floor, building or site around the people who use them.
How it works
A visit follows the same order every time: protect the area, make the system safe, do the work, tidy up and hand over the paperwork. On site, the work takes from a few hours for a compact unit to a day or more for a large one. In Dulwich Village, as across London, we usually work overnight or at weekends and hand the site back ready to open.
- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after pictures and issue the certificate and report.
How to prepare
- Tell us the best time to work, such as after service or at a weekend
- Let us know about permits to work or site inductions
- Have your last certificate or report to hand
How to get a quote
For a fixed quote, give us a ring on 0345 646 2711 or send us an email with the site type, your trading hours and a short description of the system. A few photos and your last certificate or report help a lot. We typically come back within one working day.
