AHU cleaning in Isle of Dogs, done properly
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. We clean coils with methods suited to their condition, taking care not to damage the fins. The work covers drain trays, supply and extract fans and internal panels, and the jobs we see most are drain trays holding standing water and intake sections clogged with outdoor debris.
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. In a building in Isle of Dogs, dust and debris build up in the units and ductwork over time.
The sign-off is always in writing: a dated report with pictures of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

Landlords, agents and facilities managers
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
Part by part
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe in agreement with the site.
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. We clean each section from intake to discharge.

The process
Every visit runs to the same pattern: protect the area, isolate whatever needs isolating, do the work, clear away and leave you the report. The visit itself takes anything from half a day for one small unit to several shifts for a plant room full of them. Security desks and permits-to-work are routine in London, so let us know what your building in Isle of Dogs needs from us.
- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- After photos are taken and the certificate issued.
How to prepare
- Plan for cooking equipment or plant to be off before we arrive
- Arrange a key holder or contact on site
- Mention any locked doors, roof access or ceiling voids

Isle of Dogs questions
Can ventilation in schools around Isle of Dogs be cleaned out of term?
Yes, and it’s the easiest time to do it. With about 52 schools and colleges on the FSA’s register within roughly a mile and a half of Isle of Dogs, it pays to plan holiday dates ahead. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Can the work in Isle of Dogs be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. The work in Isle of Dogs can fit around your hours. When you ring 0345 646 2711 or email us, mention when the site is quiet.
What’s included in an AHU clean?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. What happens to the filters is agreed when we quote.
Is there a report after cleaning?
Yes, a TR19® certificate and a photo report. It includes a recommended date for the next check.
What is TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
What do you do to protect the area?
By covering it before any work starts. We keep the work contained and leave the area clean.
What if parts of the system cannot be reached?
The report shows them clearly. In ductwork, new access panels are often the answer, which we can install.
Which kinds of sites do you work on?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.
Aftercare tips
Think of this as the after-treatment advice, short and simple:
- Plan the next inspection before the last report gets filed away
- Make sure the unit’s access doors open easily
- Look at the condensate drain whenever the unit is serviced
- Do not ignore odours coming through the grilles
When we’ve closed the unit up, it can be restarted with your site team. Check the drain tray is emptying over the first few days to make sure it stays clear.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.
What a clean will not put right
AHU cleaning can’t fix everything, and we’ll tell you before work begins. It will not put right:
- Mechanical faults with motors, belts or bearings
- Coils that are corroded or leaking and need replacing
- Airflow problems caused by the system’s design
If you’re not sure, just phone us on 0345 646 2711, or send details by email and we’ll give you a straight answer.

Do you need AHU cleaning in Isle of Dogs?
It matters for two reasons: the unit supplies the air people breathe, and a dirty unit has to work harder. For anyone working, learning or staying in a building in Isle of Dogs, that is air they breathe for hours at a time.
Any of these means the system needs a check-up:
- Coils clogged with dust and debris
- Plant that needs cleaning after a refit
- Blocked condensate drains and slimy trays
- Dirty fans and fan housings
Wherever a school like Harbinger Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

How we price AHU cleaning
You’ll get a fixed price before work begins. It takes into account:
- The times the site is available
- How many systems or sites are involved
- The condition we find in the survey
- Whether it’s a one-off visit or part of a schedule
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are not sure what’s needed, give us a ring on 0345 646 2711 or email us and we’ll give you an honest view and a fixed quote.
Helping us quote
To speed up the quote, send us:
- How we’d reach plant on a roof or in a plant room
- Photos showing the whole system and its surroundings
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Close-ups of filters, grilles, hatches or access panels
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
