AHU cleaning for kitchens and businesses in Brixton
An AHU clean is a thorough examination and treatment of the unit. Every section is opened, cleaned and photographed, so the report shows exactly what was done. The work covers dampers and louvres, internal panels and filter sections, and common reasons people get in touch are filters that are clogged or overdue and units needing a clean before a new tenant or handover.
Many London buildings have had their ventilation extended and altered through several fit-outs, with old runs left behind that are hard to reach. In Brixton, as elsewhere, cleaning starts with an inspection of what’s there.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

What AHU cleaning looks like in Brixton
Food Standards Agency records list about 71 schools, colleges and universities, about 72 care, childcare and hospital premises and about 7 hotels, B&Bs and guest houses registered as food businesses within 1.5 miles or so of the middle of Brixton. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. In London, ventilation plant is often on the roof or below ground, so the work is typically done out of hours. Brixton’s nearest hospital, Dulwich Community Hospital, is about 1.6 miles east. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.
If you run a surgery, dental practice or care home near Brixton, clean ventilation matters as much to you as to a hospital like Dulwich Community Hospital (about 1.6 miles east). If you manage a school such as Sudbourne Primary School, ventilation cleaning is best booked for the holidays. If you manage shops or offices close to Brixton station, a TR19® Air inspection shows whether the ductwork needs cleaning.

What happens if it’s left?
Facilities teams are often asked for evidence that the ventilation is looked after. Our certificate and photo report give you clear evidence, for audits, tenants or your own peace of mind. In Brixton, as across London, ductwork often passes through shared risers and other people’s space.
The price reflects the work, not guesswork. That is why we survey first, from pictures or on site, and the price is agreed before we start.

What else we do in Brixton
Between visits
To keep the system working properly between visits:
- Book the next check in line with the report
- Keep inspection doors on the unit in good order
- Look at the condensate drain whenever the unit is serviced
- Do not ignore odours coming through the grilles
The report shows each section of the unit before and after, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
What the work involves, part by part
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. We protect the area below before opening them.
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. We note any we find in the report.
Questions from Brixton
Can you clean school ventilation in Brixton during the holidays?
Yes, and it’s the easiest time to do it. There are about 71 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Brixton. Booking early in the term gives the best choice of holiday dates.
Can parking be tricky for a job in Brixton?
A loading bay, a visitor permit or off-street space near the site in Brixton makes the visit easier to plan. Working overnight, as we often do in London, usually makes it simpler.
What happens if you can’t reach some of it?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
What information do you need?
The site address, the type of premises and your opening hours, plus photos of the system and your last certificate or report if you have one.
Do you work with multi-site operators?
Yes. You deal with one contact for every site across London and the South East, and visits can be set on a regular cycle.
Do you do ventilation duct cleaning too?
Yes, the ductwork, grilles and diffusers the unit serves. We’ll tell you after the survey whether the ducts need it.
Can you clean the AHU out of hours?
Yes. We time the work to fit the building’s hours. In hospitals and care homes, we agree timings with the site team.
How often should an air handling unit be cleaned?
That is set by inspection, in line with TR19® Air. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
What affects the cost of AHU cleaning
Every site gets its own quote. These are the things that affect it:
- The condition of the system
- Any permits to work or inductions
- How easy every part is to reach
- Whether several sites go on one quote
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. The price is fixed before any work starts.
What to send for a quote
To help us quote quickly, send us:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Any previous report or certificate
- The postcode and the type of business
- Close-ups of filters, grilles, hatches or access panels
Every quote begins with a look at the system, from your pictures and details or, where that isn’t enough, a survey on site. Then we send a fixed price, before we start.
In-house cleaning or a specialist?
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
How the visit works
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. We fit London jobs around the building rather than the other way round, so a visit in Brixton is normally out of hours.
- First we agree when the unit can be switched off, including evenings or weekends.
- 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 photos and issue the certificate and report.
Preparing for the visit
- Tell us where we can park and unload
- Tell us about site rules, permits or sign-in
- Make sure someone can let us in and lock up afterwards
