AHU cleaning for kitchens and businesses in Leyton Grange
We clean air handling units for buildings in Leyton Grange and across Greater London, working to TR19® Air, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. If you have condensate trays that won’t empty and debris and leaves in the fresh air intake, we can put it right, from supply and extract fans, filter sections and heating and cooling coils onwards.
Many London buildings have had their ventilation extended and altered through several fit-outs, leaving sections that are hard to reach and seldom cleaned. An inspection first shows where cleaning is needed in a building in Leyton Grange.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Keeping the system healthy
Good habits slow the build-up between visits. Our tips:
- Keep the certificate and photo report with the plant records
- Stick to the filter change plan
- Note any water around the unit or leaks below it
- Make sure the unit’s access doors open easily
You receive a TR19® certificate and a photo report after the clean. They belong in the plant or maintenance log.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.
How the visit works
A visit follows the same order every time: sheeting and protection first, isolate whatever needs isolating, do the work, clear away 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 a London area like Leyton Grange, parking, loading and building access are planned before the day of the work.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- 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.
Preparing for the visit
- Name a contact who can let us in at the agreed time
- Mention any locked doors, roof access or ceiling voids
- Tell us about site rules, permits or sign-in
Ask for a quote
Here’s what helps us quote: the address, the type of site and when it’s open, a few photos and any previous report or certificate. Once you have those, phone us on 0345 646 2711, or email photos.

When something else is needed
In fairness, some problems need a different fix:
- Problems with the unit’s controls or sensors
- Airflow problems caused by the system’s design
- Coils that are corroded or leaking and need replacing
If you’re not sure, just phone us on 0345 646 2711, or send details by email and we will give you a straight answer.

Common problems we fix in Leyton Grange
Mechanical servicing keeps a unit running, but it doesn’t always include cleaning the inside. That means a unit can tick every service box and still be carrying years of dirt.
What we are most often called out for:
- Rooms that smell stuffy when the system runs
- Debris and leaves in the fresh air intake
- Units needing a clean before a new tenant or handover
- Plant that has been serviced but not cleaned
Hospitals such as Homerton University Hospital (about 1.5 miles south-west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Leyton Grange are no different.
Questions to ask before booking
- What’s included in the scope, part by part
- How VAT is shown on the quote
- How they set the interval to the next visit
- What paperwork you get at the end

Your questions about AHU cleaning in Leyton Grange
What do you need to know about parking in Leyton Grange?
A loading bay, a visitor permit or off-street space near the site in Leyton Grange makes the visit easier to plan. If the building has a loading slot system, we’ll book into it.
Do you clean school ventilation in Leyton Grange in the holidays?
Yes. The holidays are the usual time for school work. Around Leyton Grange, the Food Standards Agency lists about 38 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 send us an email with the dates the site is empty.
Do you work evenings or weekends?
Yes, if daytime working isn’t practical. We plan the shutdown window with you.
Are you accredited?
We hold CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Do you do ventilation duct cleaning too?
Yes. Ductwork is cleaned through access panels, with anything inaccessible recorded, and new panels can be fitted.
Will you repair the fan or motor?
AHU cleaning is what we offer here, not mechanical repairs. Any faults we notice are recorded for your maintenance team to follow up.
What types of premises do you cover?
Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.
What do you clean inside the unit?
Everything inside the unit that air passes over, from intake to discharge, including coils, fan and drain trays. You get a photo report showing each part before and after.
What happens if it’s left?
A clean unit feeds cleaner air into the ductwork, so the whole system stays cleaner for longer. That makes the next inspection of a building in Leyton Grange simpler. Choosing the date yourself beats having a fault choose it for you.
The cost depends on how big the system is, what state it’s in and access to every part of it. You get a fixed price before we start, so there are no surprises.
