How we handle AHU cleaning in Hoxton
No two plant rooms are the same, whether it’s a compact unit in a ceiling void or a big unit on the roof. We look at the unit first, from photos or a site visit, and give you a fixed quote, so you know where you stand. The work covers supply and extract fans, internal panels and drain trays, and people most often call us about rooms that smell stuffy when the system runs and debris and leaves in the fresh air intake.
London offices and flats often have ductwork added through successive refits, leaving sections that are hard to reach and seldom cleaned. An inspection first shows where cleaning is needed in a building in Hoxton.
Each visit ends with a written report and photos, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Why deal with it now?
Standing water in a drain tray does not clear itself. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Dealing with it early keeps the clean straightforward. London buildings are shared, so a fire or failure in one system can reach the neighbours above and beside you.
What you pay depends on how big the system is, the condition it’s in and how easy it is to reach. You get a fixed price before work begins, so there are no surprises.

Keeping the system healthy
No system stays clean for ever, but care slows the build-up. Our tips:
- Flag stale or damp smells in the supply air
- Watch for drips or damp patches near the plant
- Book the next check in line with the report
- Report stiff or damaged access doors
The report suggests a date for the next inspection or clean, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
What happens on the day
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes one overnight shift for many single units, with bigger plant phased. For a job in Hoxton, tell us about loading bays, permits, lifts and roof access when you book.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
How to prepare
- Let us know when the site is closed or quiet
- Have your last certificate or report to hand
- Allow time for equipment near the work to be turned off and cool down

Questions from Hoxton
Do you clean school ventilation in Hoxton in the holidays?
Yes. The holidays are the usual time for school work. There are about 58 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Hoxton. You can phone us on 0345 646 2711 or email us with the dates the site is empty.
Can you come to Hoxton after we close?
Yes. We work evenings, overnight and at weekends. That way a site in Hoxton doesn’t have to lose a day’s trading. Your opening times are the first thing we ask for.
What do you do with what you remove?
It leaves the site with us at the end of the visit. During the work, it’s contained so the area stays clean.
Is there a report after cleaning?
Yes. You get a TR19® certificate plus before and after photos. They’re worth keeping with the plant records.
Can you fix a faulty AHU?
AHU cleaning is what we offer here, not mechanical repairs. If we spot a fault, we note it in the report for your maintenance team to follow up.
Can you price the work without visiting?
Yes, where the pictures show enough. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
Which parts of an air handling unit do you clean?
Every section that collects dirt: filters, coils, tray, fan and panels. We confirm the scope after looking at the unit.
What does TR19 mean?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.

Fixed quotes for AHU cleaning in Hoxton
The survey tells us what the work involves. The main factors are:
- Whether it’s a one-off visit or part of a schedule
- Site requirements such as sign-in and permits
- What state the system is in
- When the work can happen, such as evenings, overnight or weekends
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account, and the price is fixed before any work starts.
Helping us quote
Photos let us diagnose from a distance. The most useful are:
- Detail shots of panels, filters and grilles
- Any previous report or certificate
- Your opening hours and when the area is out of use
- Where the plant sits or the system leaves the building, such as a roof or outside wall
For AHU cleaning in Hoxton, call 0345 646 2711 or email us. Tell us what kind of premises it is and when it’s open, and send pictures or your last report if you can. A fixed quote usually follows within one working day.
Staff cleaning versus specialist work
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We’ll take a look and give you a fixed quote.

When to call us in Hoxton
An overdue filter loads up with dirt, which cuts the airflow and can let air slip round the filter. After that, the coils and fan collect what the filter should have caught.
Signs it’s time to call us include:
- Fan sections that haven’t been cleaned in years
- Dust-coated heating and cooling coils
- Debris and leaves in the fresh air intake
- Odours coming through the supply air
If you manage a school such as Shoreditch Park Primary School, ventilation cleaning is best booked for the holidays.
