AHU cleaning in Forest Gate
The fan pushes every bit of air in the system, so dust on its blades and housing ends up in the airstream. Fan, housing and the surrounding panels are cleaned as part of the job, with the unit switched off and made safe first. If you are dealing with drain trays holding standing water and dirty fans and fan housings, we can help, from internal panels, drain trays and filter sections onwards.
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 Forest Gate, dust settles in the units and ducts year after year, which is what TR19® Air cleaning deals with.
The report is your system’s health record: a dated account with pictures of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

Part by part
Internal casing and panels
We open each section through its doors and close them securely when we’re done before the unit is handed back.
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. Access is planned during the survey so the quote reflects it.
Common questions in Forest Gate
Does London parking affect a job in Forest Gate?
A loading bay, a visitor permit or off-street space near the site in Forest Gate makes the visit easier to plan. Much of our London work is done overnight, which helps.
Do you work overnight in Forest Gate?
Yes, out-of-hours work is a big part of what we do. The work in Forest Gate can fit around your hours. Your opening times are the first thing we ask for.
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.
What do you do to protect the area?
By covering it before any work starts. The work is kept contained and clean down when we finish.
What do you do with what you remove?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on, so it doesn’t spread.
Can you price the work without visiting?
Typically, yes. Send a few wide photos plus close-ups of panels, filters or grilles, and a fixed quote usually follows within one working day. If pictures are not enough, we will survey first.
What is TR19?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Is Forest Gate in your area?
Yes. We cover Forest Gate and across Greater London, within our South East and London area. For a fixed quote, ring 0345 646 2711 or drop us a line.
Managing agents and facilities teams in Forest Gate
We regularly work with managing agents. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.
Whether it’s one building or many, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with pictures.
When to call us in Forest Gate
Mechanical servicing keeps a unit running, but it doesn’t always include cleaning the inside. That means a unit can tick every service box and still be carrying years of dirt.
Keep an eye out for any of the following:
- Dust-coated heating and cooling coils
- Fan sections that haven’t been cleaned in years
- Debris and leaves in the fresh air intake
- Units that have only ever had filter changes
School buildings such as Woodgrange Infant School are usually done in the holidays, so classrooms are not disturbed.
Before booking anyone
- Whether the whole system is included, or only the parts that are easy to reach
- Whether the quote is based on a survey or photos
- Whether the price is fixed
- Proof of accreditation you can verify
How the visit works
Night work is normal for us. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. The visit itself takes anything from half a day for one small unit to several shifts for a plant room full of them. Loading bays, visitor permits and roof access are the first things we ask about for a site in Forest Gate.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Make sure equipment near the work can be switched off and left to cool
- Clear loose items from the work area
- Have your last certificate or report to hand
How to get a quote
There’s no standard price list, because no two systems are the same. We look at your system first, from pictures or on a visit, then send a fixed quote. To get going, call 0345 646 2711, or email photos.

Fixed quotes for AHU cleaning in Forest Gate
Every site gets its own quote. This is what makes a difference:
- Any permits to work or inductions
- The condition we find in the survey
- Working hours and out-of-hours timing
- Whether we need access equipment or extra panels
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we will explain each part.
What we need to know
Many jobs can be priced from photos and some basics. Useful things to send:
- The postcode and the type of business
- Photos showing the whole system and its surroundings
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Any access panels or hatches you can see
The quickest way to a quote is to send pictures: 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.
Why act early in Forest Gate
A clean unit feeds cleaner air into the ductwork, so the whole system stays cleaner for longer. That makes the next inspection of a building in Forest Gate simpler. A busy site in Forest Gate builds up dirt and wear quickly, so putting it off makes the eventual job larger.
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.
