AHU cleaning in North Woolwich, done properly
Our AHU cleans for sites in North Woolwich cover the parts that collect dirt: the filter section, heating and cooling coils, drain trays, fan and casing. You get a TR19® certificate and a photo report showing the unit before and after. If you have odours coming through the supply air and debris and leaves in the fresh air intake, we can help, from dampers and louvres, supply and extract fans and internal panels 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 North Woolwich, dust settles in the units and ducts year after year, which is what TR19® Air cleaning deals with.
Good records are part of the job. Each visit is written up with photos, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Why it’s worth doing now in North Woolwich
When the unit is clean, less dirt reaches the ducts, so the ducts and grilles stay cleaner between cleans. It also means the next inspection has less to find. London sites work long hours, and the longer a job is left, the bigger it gets.
The price reflects the work, not guesswork. That is why we survey first, from pictures or on site, and the price is agreed before work begins.

Different parts, different methods
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. A clean gets air moving through the coil properly again.
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated in agreement with the site.
How we price AHU cleaning
Before we fix a price, we need to know a few things. We look at:
- A single visit or a regular plan
- The times the site is available
- The size of the system
- Any permits to work or inductions
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re not sure what’s needed, call 0345 646 2711 or email us and we’ll give you an honest view and a fixed quote.
What to send for a quote
To speed up the quote, please include:
- Your last certificate, test record or report
- The times we could work without disrupting the site
- Any symptoms, from odd noises to smells or leaks
- Detail shots of panels, filters and grilles
Quoting starts with a diagnosis, from your photos and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work so you know the cost before any work starts.
Multi-site and managed buildings
Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
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.

How long will the unit be out of action?

Do you cover North Woolwich?

Yes. One number covers all your sites across London and the South East, with visits on a regular schedule.
How often do AHUs need cleaning?
It depends on the unit, the filters and how the building is used. Regular inspection shows when it’s due, and the report recommends a next date.
How much notice do you need?
Book as early as you can for planned work, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
What we are called out for in North Woolwich
Whatever surrounds a building in North Woolwich, the air drawn into its AHU carries dust, pollen and debris. Most of it lands at the intake and the first stage of filters, and the finer material travels on.
It’s time to book a visit if you see:
- Air handling units with blocked filters
- Air handling units due a clean after building work
- Dust built up on fan impellers
- Plant that has been serviced but not cleaned
For workplaces around Woolwich Dockyard station with mechanical ventilation, cleaning can be done in the evening or at weekends.

The process
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes a single shift for a typical unit, longer for large or heavily soiled ones. Most London sites can’t stop for the day, so work in North Woolwich is typically done overnight, early in the morning or at weekends.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Getting ready for the visit
- Arrange a key holder or contact on site
- Plan for cooking equipment or plant to be off before we arrive
- Tell us the best time to work, such as after service or at a weekend

Advice
Aftercare tips
Good habits slow the build-up between visits. Our tips:
- Report musty smells from the vents straight away
- Make sure condensate is draining away
- Keep filter changes on time and recorded
- Keep the certificate and photo report with the plant records
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
