Brockley Hill AHU cleaning

For landlords and multi-site operators
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
We also work for facilities teams across offices, schools and healthcare in Brockley Hill and across Greater London. Larger estates can be phased building by building around the people who use them.
AHU cleaning in Brockley Hill, done properly
Our AHU cleans for sites in Brockley Hill cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. Every clean comes with a TR19® certificate and before and after pictures in a report. If you have units that have only ever had filter changes and stale or musty smells from the ventilation, we can put it right.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so ventilation cleaning in Brockley Hill is normally planned out of hours. Parking and loading are agreed with the building in advance.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Why it’s worth doing now in Brockley Hill
If people in a building in Brockley Hill complain about stuffy or smelly air, the AHU is worth looking at. Cleaning it deals with the cause rather than the symptom. Leaving it on a busy London site only adds to the work.
Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote, and the price is fixed before we start.

How we price AHU cleaning
Every site gets its own quote. This is what makes a difference:
- The condition we find in the survey
- How big the system is
- Where the site is and how we reach it
- The number of sites or systems
You will not find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll talk you through it.
Helping us quote
Photos and a few facts are often enough to price the work. Useful things to send:
- Detail shots of panels, filters and grilles
- The site address and the type of premises
- A few general shots of the system
- The roof, plant room or outside wall the system runs to

Brockley Hill: your questions answered
Do you clean school ventilation in Brockley Hill in the holidays?
Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 13 schools, colleges and universities with registered kitchens within about a mile and a half of Brockley Hill. Just give us a ring on 0345 646 2711 or send us an email with your term dates and we will plan around them.
Can you work in Brockley Hill outside opening hours?
Yes, out-of-hours work is a big part of what we do. The work in Brockley Hill can fit around your hours. Your opening times are the first thing we ask for.
How do you protect the area?
We cover floors and nearby surfaces with sheeting before we start, and waste is contained as we go. At the end, the area is cleaned down.
How often should an air handling unit be cleaned?
TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. Each report suggests when the unit should next be looked at.
Do you clean the ductwork as well?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. It’s often worth doing both at once, and we can quote for both.
Which parts of an air handling unit do you clean?
All the internal parts the air touches, from intake to discharge, including coils, fan and drain trays. The photo report shows each section before and after.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Does the AHU have to be shut down for cleaning?
Yes. The fan must be stopped and the unit isolated, and we time the work to suit the site.
In-house cleaning or a specialist?
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. Reaching it takes a specialist with the right equipment.
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
Signs you need AHU cleaning in Brockley Hill
Wherever there’s a cooling coil, there’s condensate. A blocked outlet or a badly sloped tray leaves standing water, and slime and smells soon follow.
Keep an eye out for these warning signs:
- Dust built up on fan impellers
- Debris and leaves in the fresh air intake
- Dirty coils holding back the airflow
- Plant that needs cleaning after a refit
School buildings such as London Academy are typically done in the holidays, so classrooms are not disturbed.

What happens on the day
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. The visit takes half a day to a full day per unit, with large plant planned over several shifts. For a job in Brockley Hill, tell us about loading bays, permits, lifts and roof access when you book.
- 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.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
How to prepare

- Make sure someone can let us in and lock up afterwards

Looking after it afterwards
Aftercare is simple, and it helps at the next visit:
- Keep the certificate and photo report with the plant records
- Keep the area around the fresh air intake clear
- Stick to the filter change plan
- Report musty smells from the vents right away
The report suggests a date for the next inspection or clean, taking into account how dirty it was. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Keep the unit’s doors and panels in working order. Sections that are awkward to open are the ones that get skipped.
