- Dirty fans and fan housings
- Odours coming through the supply air
- Air handling units with blocked filters
Keeping the system healthy
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Plan the next inspection before the last report gets filed away
- Make sure condensate is draining away
- Report musty smells from the vents right away
- Watch for drips or damp patches near the plant
You receive a TR19® certificate and a photo report after the clean. Keep both with the building’s maintenance records.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
AHU cleaning in Hornchurch, done properly
Our AHU cleaning covers sites in Hornchurch and the rest of Greater London, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. Common call-outs are for dirty filters cutting the airflow and dirty fans and fan housings, across internal panels, supply and extract fans and drain trays.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so ventilation cleaning in Hornchurch is typically planned out of hours. Parking and loading are agreed with the building in advance.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

Your questions about AHU cleaning in Hornchurch
Do you work at weekends in Hornchurch?
Yes, nights and weekends are routine for us. The work in Hornchurch can fit around your hours. Your opening times are the first thing we ask for.
Can a school’s ventilation in Hornchurch be done out of term time?
Yes. The holidays are the usual time for school work. With about 33 schools and colleges on the FSA’s register within roughly a mile and a half of Hornchurch, it pays to plan holiday dates ahead. Tell us your holiday dates and we will book the visit for when the site is empty.
Do you need to switch the unit off?
Yes. We can’t clean a running unit, so it’s switched off and made safe first. We agree the timing with your site team.
Are you accredited?
Our accreditations are CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Can you fix a faulty AHU?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We will flag anything we notice during the clean.
Which kinds of sites do you work on?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
Where does the waste go?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. None of it is left on site.
What’s included in an AHU clean?
The main parts are the filters, coils, drain tray, fan and inside of the casing. The survey confirms what’s in your unit before we quote.
How it works
Every visit runs to the same pattern: sheeting and protection first, isolate whatever needs isolating, carry out the AHU cleaning, clear away and leave you the report. The visit itself takes from a few hours for a compact unit to a day or more for a large one. Night and weekend working is normal for us in London, and a site in Hornchurch is no exception.
- 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.
- The fan and drain tray are cleaned and the drain checked.
- We take after photos and issue the certificate and report.
Preparing for the visit
- Clear loose items from the work area
- Tell us about site rules, permits or sign-in
- Arrange a key holder or contact on site
How to get a quote
Here’s what helps us quote: the address, the type of site and when it’s open, pictures of the system and the last certificate or report, if there is one. Once you have those, phone us on 0345 646 2711 or use the quote form.

Hornchurch buildings and their air
Food Standards Agency records list about 33 schools, colleges and universities and about 56 caring premises (care homes, nurseries and hospitals) registered as food businesses across Hornchurch and its immediate surroundings (about a mile and a half). Buildings like these often rely on mechanical ventilation, which TR19® Air covers. In London, ventilation plant is often on the roof or below ground, so the work is typically done out of hours. About 0.9 miles south of Hornchurch is St George's Hospital, the nearest hospital. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
If you run a surgery, dental practice or care home near Hornchurch, clean ventilation matters as much to you as to a hospital like St George's Hospital (about 0.9 miles south). Workplaces around Emerson Park station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.

Signs you need AHU cleaning in Hornchurch
Cooling coils create condensation, and that water has to go somewhere. If the drain tray outlet blocks or the tray doesn’t fall properly, water stands in it, and that is where slime and odours start.
Look out for any of the following:
- Air handling units due a clean after building work
- Condensate trays that will not empty
- Units that have only ever had filter changes
- Intake sections clogged with outdoor debris
If you manage a school such as Langtons Infant School, ventilation cleaning is best booked for the holidays.
Questions to ask before you book
- Whether the whole system is included, or only the parts that are easy to reach
- Whether the figure could change on the day
- When the next visit should be, and why
- What records you’ll receive afterwards
Why it’s worth doing now in Hornchurch
Tenants, auditors and owners may want proof that the air handling plant is kept clean. A TR19® certificate and photo report give you that, for audits, tenants or your own peace of mind. London sites work long hours, and the longer a job is left, the bigger it gets.

What staff can safely do
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.

Part by part
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. The coil and its drain tray are cleaned as one job.
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. Anything like that is recorded with pictures.
