AHU cleaning for kitchens and businesses in Broadfields Estate
Coils are where a lot of the dirt ends up. Dirt on the fins holds back air and makes the unit work harder to do the same job. Coils are cleaned carefully, with methods chosen so the fins are not flattened. Typical jobs include dirty fans and fan housings and coils clogged with dust and debris, on dampers and louvres, heating and cooling coils and filter sections.
London buildings tend to keep their plant on the roof or below ground, so ventilation cleaning in Broadfields Estate is typically planned out of hours. Parking and loading are agreed with the building in advance.
We’ve been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

Looking after it afterwards
Simple habits between visits make a real difference. We recommend:
- Report water on the plant room floor
- Report musty smells from the vents straight away
- Plan the next inspection before the last report gets filed away
- Look at the condensate drain whenever the unit is serviced
Once the clean is done, we send a TR19® certificate and a report with before and after photos. Keep both with the building’s maintenance records.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
What happens on the day
Your staff don’t need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Afterwards, the area is left tidy and the written report follows. Most London sites can’t stop for the day, so work in Broadfields Estate is usually done overnight, early in the morning or at weekends.
- We agree a shutdown window that suits the building.
- 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 pictures and issue the certificate and report.
How to prepare
- Find the previous report, if there is one
- Let us know how we reach the system, including roofs, risers and plant rooms
- Agree a time when the area can be out of use

What staff can safely do
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
For landlords and multi-site operators
From a single site to a large estate, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with pictures.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side, and the report can go to both.

What affects the cost of AHU cleaning
The survey tells us what the work involves. The main factors are:
- Site requirements such as sign-in and permits
- Travel, parking and unloading
- What state the system is in
- The times the site is available
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re not sure what’s needed, ring 0345 646 2711, or send details by email for straight advice and a fixed quote.
Helping us quote
Photos and a few facts are often enough to price the work. Useful things to send:
- The roof, plant room or outside wall the system runs to
- Your last certificate, test record or report
- Detail shots of panels, filters and grilles
- The postcode and the type of business
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.
What the work involves, part by part
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. Anything like that is recorded with pictures.
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. We clean the intake and first stage of filters along with the rest.
When to call us in Broadfields Estate
An overdue filter loads up with dirt, which cuts the airflow and can let air slip round the filter. Then the rest of the unit takes the load.
What we are most often called out for:
- Dust-coated heating and cooling coils
- Dirty filters cutting the airflow
- Drain trays holding standing water
- Debris and leaves in the fresh air intake
Wherever a school like Rosh Pinah Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
What your quote should include
- Which accreditations they hold, and whether you can check them
- Whether the work can be done while the site is closed
- Exactly which parts of the system are covered
- How they set the interval to the next visit

Broadfields Estate: your questions answered
Do you do school ventilation cleaning in Broadfields Estate in the summer holidays?
Yes, holiday work suits schools best. There are about 21 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Broadfields Estate. Just ring 0345 646 2711, or send details by email with your term dates and we’ll plan around them.
Is parking a problem for work in Broadfields Estate?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Much of our London work is done overnight, which helps.
Can you come out in an emergency?
Yes. Our emergency line runs 24/7 for anything that cannot wait until a planned visit. Ring any time and tell us what’s happened.
What does TR19 mean?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Where does the waste go?
We contain it and take it with us. We collect grease, debris and waste water as we go rather than letting it spread.
When should our AHU next be cleaned?
There’s no single answer; it comes down to the building and the unit. Inspection tells you when cleaning is needed, and we will suggest an interval after the first clean.
What about areas you can’t get to?
They’re marked on the report. In ductwork, new access panels are often the answer, and we can fit those.
Which parts of an air handling unit do you clean?
Every section that collects dirt: filters, coils, tray, fan and panels. The survey confirms what’s in your unit before we quote.
