AHU cleaning for kitchens and businesses in Willesden
We clean the parts of the unit where dirt and moisture gather: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. If you have coils clogged with dust and debris and air handling units never cleaned inside, we can put it right, from supply and extract fans, internal panels and filter sections onwards.
London buildings tend to keep their plant on the roof or below ground, so work in Willesden is often done in the evening or at weekends. Parking and loading are agreed with the building in advance.
A written report with pictures follows each visit, 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 act early in Willesden
Dirt left in an air handling unit doesn’t stay in the unit. It’s carried through the ductwork and out of the grilles, so cleaning the ducts without the unit only goes so far. It’s better booked as a planned job in Willesden than handled as an emergency.
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before any work starts.
Why Willesden businesses choose us
- One contact for all your sites in London and the South East
- A fixed price before any work starts

How the job changes from site to site
Filters
Filter condition tells you a lot about the rest of the unit. We photograph them for the report.
Drain trays
Condensate from the coil drips into a tray beneath it. We clear standing water, clean out slime and check the outlet is draining.

Keeping the system healthy
Good habits slow the build-up between visits. A few tips:
- Don’t store bins or materials near the intake
- Keep inspection doors on the unit in good order
- File each AHU report in the maintenance log
- Report water on the plant room floor
Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
Do you need AHU cleaning in Willesden?
Whatever surrounds a building in Willesden, the air drawn into its AHU carries dust, pollen and debris. The intake section and first filters take the brunt, and the finer material travels on.
Keep an eye out for these warning signs:
- Units that have only ever had filter changes
- Dust built up on fan impellers
- Odours coming through the supply air
- Blocked condensate drains and slimy trays
If you run a surgery, dental practice or care home near Willesden, clean ventilation matters as much to you as to a hospital like St Andrew's Hospital (about 0.9 miles north).

How the visit works
We start by comparing what we find with the survey or your photos. Anything unexpected is raised with you before we go further. From there, it takes half a day to a full day per unit, with large plant planned over several shifts. In Willesden, as across London, we typically work overnight or at weekends and hand the site back ready to open.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- After photos are taken and the certificate issued.
Getting ready for the visit
- Mention any parking or loading restrictions
- Make sure someone can let us in and lock up afterwards
- Let us know when the site is closed or quiet
How to get a quote
Getting a quote doesn’t take long. Send a few details and photos, and we typically reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.

What affects the cost of AHU cleaning
Every site gets its own quote. This is what makes a difference:
- One-off work versus a regular cycle
- The condition of the system
- When the work can happen, such as evenings, overnight or weekends
- The size of the system
The cost depends on the size of the system, what state it’s in and access to every part of it. We give you a fixed price before any work starts, so there are no surprises.
Helping us quote
We can often survey from pictures. The most useful are:
- Any access panels or hatches you can see
- Photos showing the whole system and its surroundings
- Any symptoms, from odd noises to smells or leaks
- The paperwork from the last visit, if you have it
For AHU cleaning in Willesden, call us on 0345 646 2711 or drop us a line. 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 normally follows within one working day.
For landlords and multi-site operators
We regularly work with managing agents. Send the address, what’s needed and how access works, and we will send a fixed quote.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.

Yes. Half-terms and the summer break are the natural time for school work. With about 56 schools and colleges on the FSA’s register within roughly a mile and a half of Willesden, it pays to plan holiday dates ahead. Tell us your holiday dates and we will book the visit for when the site is empty.
Can parking be tricky for a job in Willesden?
Tell us where a van can stop near your site in Willesden, and about any building rules on loading. Much of our London work is done overnight, which helps.
Can one contract cover all our sites?
Yes. Our area covers London and the South East, so we can schedule a run of sites as one programme. Every site has its own report.
What should I send you?
A short description and a few photos, with the address and opening hours. We will ask for anything else we need.
How much notice do you need?
The more notice, the better, particularly for night and weekend visits. Quotes normally come back within one working day, and there’s a 24/7 line for emergencies.
What happens if you can’t reach some of it?
They’re marked on the report. In ductwork, new access panels are often the answer, which we can install.

Willesden buildings and their air
Going by the FSA’s register, there are about 56 schools, colleges and universities, about 45 caring premises (care homes, nurseries and hospitals) and about 5 hotels and guest houses serving food within about 1.5 miles of central Willesden. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. London plant rooms are often on roofs or in basements reached through occupied floors. St Andrew's Hospital is the nearest hospital, about 0.9 miles north of Willesden. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
School buildings such as St Andrew and St Francis CofE Primary School are typically done in the holidays, so classrooms aren’t disturbed.
