AHU cleaning for kitchens and businesses in Wembley
Think of an AHU clean as a full check-up for the ventilation. Every section is opened, cleaned and photographed, so the report shows exactly what was done. Typical jobs include air handling units with blocked filters and intake sections clogged with outdoor debris, across dampers and louvres, drain trays and internal panels.
London offices and flats often have ductwork added through successive refits, with old runs left behind that are hard to reach. An inspection first shows where cleaning is needed in a building in Wembley.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Why act early in Wembley
If people in a building in Wembley complain about stuffy or smelly air, the AHU is worth looking at. A clean tackles the source instead of masking it. In Wembley, a planned overnight visit is much easier than closing unexpectedly.
What you pay reflects the actual work. That is why every job is surveyed first, and the price is agreed before we start.

When something else is needed
A few issues sit outside what this work can do:
- Coils that are corroded or leaking and need replacing
- Faulty motors, drives or bearings
- Ductwork downstream of the unit, which is a separate clean
If in doubt, give us a ring on 0345 646 2711 or send us an email and we will say what we think.
Where we work
- Dampers and louvres
- Filter sections
- Supply and extract fans
- Internal panels
- Heating and cooling coils
- Drain trays
What the work involves, part by part
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. We clean the impeller, housing and surrounding section.
Internal casing and panels
We open each section through its doors and close them securely when we’re done, and check every one is shut.
Multi-site and managed buildings
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
From a single site to a large estate, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with photos.
AHU cleaning in Wembley: local notes
Food Standards Agency data includes about 28 schools, colleges and universities, about 59 care, childcare and hospital premises and about 8 hotels and guest houses within about 1.5 miles of central Wembley. Busy, occupied buildings like these are where clean supply air matters most. In London, ventilation plant is often on the roof or below ground, so the work is normally done out of hours. Wembley’s nearest hospital, St. Mark's Hospital, is about 1.5 miles north-west. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Hospitals such as St. Mark's Hospital (about 1.5 miles north-west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Wembley are no different. If you manage shops or offices close to North Wembley station, a TR19® Air inspection shows whether the ductwork needs cleaning. If you manage a school such as Wembley Primary School, ventilation cleaning is best booked for the holidays.

Wembley questions
Can a school’s ventilation in Wembley be done out of term time?
Yes. The holidays are the usual time for school work. Around Wembley, the Food Standards Agency lists about 28 schools and colleges with registered kitchens within a mile and a half or so. You can give us a ring on 0345 646 2711 or email us with the dates the site is empty.
Do you work at weekends in Wembley?
Yes, we can come after you close and finish before you open. That way a site in Wembley doesn’t have to lose a day’s trading. Let us know the hours you are closed and we’ll book within them.
How much does AHU cleaning cost?
There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before we start.
What information do you need?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. After that, simply phone us on 0345 646 2711 or drop us a line.
Do you have insurance?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
What do you clean inside the unit?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. What happens to the filters is agreed when we quote.
How far ahead should we book?
Earlier is better, especially for out-of-hours work. We normally quote within one working day, and there’s a 24/7 line for emergencies.
What do you do to protect the area?
We cover floors and nearby surfaces with sheeting before we start, and anything we remove is contained. Before we leave, we tidy up and clean down.
Looking after it afterwards
Aftercare is simple, and it helps at the next visit:
- Flag stale or damp smells in the supply air
- Change filters on schedule and log each change
- Make sure the unit’s access doors open easily
- Look at the condensate drain whenever the unit is serviced
Restart the unit with your site team or maintenance contractor once we have finished. Keep an eye on the condensate drain over the next few days to confirm water is draining away.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
