AHU cleaning in Berry's Green, done properly
Our AHU cleans for sites in Berry's Green cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. We are often asked to deal with leaves and litter drawn into the unit and stale or musty smells from the ventilation, on drain trays, supply and extract fans and heating and cooling coils.
Across London, offices, hotels, schools and healthcare buildings rely on mechanical ventilation, much of it supplied through air handling units on roofs or in basements. For a building in Berry's Green, dust settles in the units and ducts year after year.
Every visit ends with a written report and photos, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

What affects the quote in Berry's Green
Some jobs are bigger than they look, and some smaller. The main factors:
- The condition we find in the survey
- Travel, parking and unloading
- How big the system is
- The number of sites or systems
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.
What we need to know
You do not need the technical terms. It helps if you can send:
- Any symptoms, from odd noises to smells or leaks
- Photos showing the whole system and its surroundings
- The postcode and the type of business
- The times we could work without disrupting the site
If you need AHU cleaning in Berry's Green, ring 0345 646 2711, or email photos. Tell us what kind of premises it is and when it’s open, plus pictures or the previous report if they’re to hand. A fixed quote typically follows within one working day.

Keeping the system healthy
A little care between visits keeps the system in better shape. Our advice:
- Keep filter changes on time and recorded
- Keep the certificate and photo report with the plant records
- Plan the next inspection before the last report gets filed away
- Report musty smells from the vents right away
The report shows each section of the unit before and after, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.
How it works
There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. The middle part takes longest, which takes from a few hours for a compact unit to a day or more for a large one. Expect the work in Berry's Green to happen after your last customer leaves, not during trading.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- We clean out the drain tray and make sure it drains.
- You get a TR19® certificate and a photo report.
Before we arrive
- Plan for cooking equipment or plant to be off before we arrive
- Let us know about parking and loading
- Find the previous report, if there is one

Questions from Berry's Green
Is AHU cleaning available in Berry's Green?
Yes, Berry's Green is covered. Just phone us on 0345 646 2711 or send us an email with a few details of the site.
Does London parking affect a job in Berry's Green?
A loading bay, a visitor permit or off-street space near the site in Berry's Green makes the visit easier to plan. Night visits tend to make loading easier on London streets.
What’s TR19?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t law, but it’s the benchmark.
Which sectors do you work in?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
Will the ventilation be off while you clean?
Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.
How do you protect the area?
We cover floors and nearby surfaces with sheeting before any work starts, and waste is contained as we go. Before we leave, we tidy up and clean down.
Will you repair the fan or motor?
The clean includes noting faults, but repairs sit with your maintenance contractor, with the details in the report.
Will we get paperwork for the AHU clean?
Yes, both a certificate and a report with pictures. The report also suggests when the unit should next be inspected.
Signs you need AHU cleaning in Berry's Green
Filters that aren’t changed or cleaned on time clog up, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
These are the problems we see most often:
- Intake sections clogged with outdoor debris
- Odours coming through the supply air
- Fan sections that haven’t been cleaned in years
- Coils clogged with dust and debris
If you manage a school such as Cudham Church of England Primary School, ventilation cleaning is best booked for the holidays.

Why act early in Berry's Green
If people in a building in Berry's Green complain about stuffy or smelly air, the AHU is worth looking at. Cleaning it deals with the cause rather than the symptom. London sites work long hours, and the longer a job is left, the bigger it gets.
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we will explain each part.
