What happens on the day
Your staff do not need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. We fit London jobs around the building rather than the other way round, so a visit in Dagenham is typically out of hours.
- 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.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
How to prepare
- Tell us about site rules, permits or sign-in
- Move anything stored near the system
- Make sure equipment near the work can be switched off and left to cool
Getting a quote
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.

About our AHU cleaning in Dagenham
An AHU clean is a thorough examination and treatment of the unit. We look inside each section, clean what we find and record it with pictures, so the report shows exactly what was done. The work covers heating and cooling coils, drain trays and filter sections, and people most often call us about dirty fans and fan housings and odours coming through the supply air.
Many London buildings have had their ventilation extended and altered through several fit-outs, with old runs left behind that are hard to reach. An inspection first shows where cleaning is needed in a building in Dagenham.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Managing agents and facilities teams in Dagenham
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
From a single site to a large estate, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Common problems we fix in Dagenham
It matters for two reasons: the unit supplies the air people breathe, and a dirty unit has to work harder. For anyone working, learning or staying in a building in Dagenham, that’s air they breathe for hours at a time.
These are the problems we see most often:
- Plant that needs cleaning after a refit
- Air handling units never cleaned inside
- Coils clogged with dust and debris
- Dust built up on fan impellers
If you manage a school such as Village Infants' School, ventilation cleaning is best booked for the holidays.
Questions to ask before booking
- When the next visit should be, and why
- Whether a survey comes first
- Whether they’re fully insured
- How areas they cannot reach will be recorded
How the job changes from site to site
Drain trays
Standing water in a tray sits right where the air passes. We clean it and note if the slope or the drain needs attention.
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. We clean the impeller, housing and surrounding section.
Looking after it afterwards
After the visit, a few habits help the work last:
- Book the next check in line with the report
- File each AHU report in the maintenance log
- Report musty smells from the vents right away
- Make sure the unit’s access doors open easily
Stick to the filter change schedule, because good filters protect everything downstream. Log every change so it’s easy to see when the next is due.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
Dagenham questions
Can you come to Dagenham after we close?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. When you phone us on 0345 646 2711 or email us, mention when the site is quiet.
What do you need to know about parking in Dagenham?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Working overnight, as we often do in London, usually makes it simpler.
Where does the waste go?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. We do not leave it behind.
Which kinds of sites do you work on?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
Which parts of an air handling unit do you clean?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. What happens to the filters is agreed when we quote.
Is a quote from photos possible?
Yes, if we can see what we need. If not, a site survey comes first, then a fixed quote.
Are you insured?
Yes. We are fully insured, and the details are available on request.
Is there a report after cleaning?
Yes. Every clean comes with a TR19® certificate and a photo report. They’re worth keeping with the plant records.
What staff can safely do
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Ventilation in Dagenham buildings
There are about 44 schools, colleges and universities and about 27 hospitals, care homes and childcare premises on the FSA’s food hygiene register within 1.5 miles or so of the middle of Dagenham. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. The nearest hospital to Dagenham is Rush Green Hospital, about 1.5 miles north-east. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. Getting kit to a London plant room normally means lifts, stairs and an agreed loading slot.
Rush Green Hospital, about 1.5 miles north-east, is the nearest hospital to Dagenham, and healthcare sites of every size need their supply air kept clean.

How we price AHU cleaning
There’s no set price list, because sites vary so much. What we look at:
- Any permits to work or inductions
- How many systems or sites are involved
- Whether we need access equipment or extra panels
- A single visit or a regular plan
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we will explain each part.
Asking for a quote
A few details help us quote accurately. When you get in touch, it helps to send:
- How we’d reach plant on a roof or in a plant room
- The site address and the type of premises
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Your opening hours and when the area is out of use
For a fixed quote, give us a ring on 0345 646 2711 or send us an email and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. You’ll typically have a quote within one working day.
