London Fields AHU cleaning
Specialist AHU cleaning for London Fields: a survey, a fixed price, careful work and proper paperwork. Call for a fixed quote.
- Plant that has been serviced but not cleaned
- Blocked condensate drains and slimy trays
- Coils clogged with dust and debris
What staff can safely do
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
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.
AHU cleaning in London Fields, done properly
An air handling unit is the heart of a building’s ventilation: air is pulled in, filtered, conditioned and sent out through the ducts. Anything that collects inside the unit can end up in the rooms it serves, so cleaning the unit matters as much as cleaning the ducts. If you’re dealing with drain trays holding standing water and units needing a clean before a new tenant or handover, we can help, from heating and cooling coils, filter sections and drain trays onwards.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. In a building in London Fields, dust and debris build up in the units and ductwork over time, which is what TR19® Air cleaning deals with.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

Signs you need AHU cleaning in London Fields
Air handling units are typically tucked away on roofs, in plant rooms or above ceilings and are rarely seen by anyone but maintenance staff. It’s easy for a long time to go by without anyone opening the panels.
Clients normally contact us when they notice something like this:
- Plant that needs cleaning after a refit
- Debris and leaves in the fresh air intake
- Dirty fans and fan housings
- Condensate trays that won’t empty
Healthcare buildings such as German Hospital, about 0.6 miles north-west, depend on their ventilation; if you manage a surgery, clinic or care home near London Fields, yours matters too.
Before you book anyone
- What happens if part of the system can’t be accessed
- Proof of accreditation you can verify
- Whether the work can be done while the site is closed
- How they set the interval to the next visit
What we do, step by step
At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. All told, the work takes half a day to a full day per unit, with large plant planned over several shifts. In London Fields, as across London, we normally work overnight or at weekends and hand the site back ready to open.
- 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 photos and issue the certificate and report.
How to prepare
- Have your last certificate or report to hand
- Agree a time when the area can be out of use
- Let us know how we reach the system, including roofs, risers and plant rooms

London Fields: your questions answered
Can a school’s ventilation in London Fields be done out of term time?
Yes, holiday work suits schools best. Food Standards Agency records list about 58 schools, colleges and universities with registered kitchens within about a mile and a half of London Fields. Booking early in the term gives the best choice of holiday dates.
Do you work overnight in London Fields?
Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in London Fields needn’t be disturbed. Let us know the hours you’re closed and we will book within them.
Do you repair air handling units?
AHU cleaning is what we offer here, not mechanical repairs. Any faults we notice are recorded so your maintenance contractor can deal with it.
Can you come out in an emergency?
Yes, day and night, every day of the year. Our office is open from 8am to 6pm on weekdays, and the emergency line covers the rest.
What does AHU cleaning cost?
It depends on the site, so we quote each one individually. To get one, call us on 0345 646 2711, or send details by email with the site type, opening hours and a few pictures.
Do you cover London Fields?
Yes. We cover London Fields and the rest of Greater London, as part of our work across South East England and London. For a fixed quote, call us on 0345 646 2711 or email us.
Do you look at the system first?
Yes, always. Diagnosis comes before treatment: the survey shows what needs doing and what access we need, and the quote is based on that.
How long will the unit be out of action?
As a guide, it takes half a day to a full day per unit, with large plant planned over several shifts. The shutdown is planned to fit, out of hours if needed.
What the work involves, part by part
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. We protect the area below before opening them.
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. The coil and its drain tray are cleaned as one job.
Keeping the system healthy
So the system stays in good health:
- Clear leaves and litter away from the intake
- Watch for drips or damp patches near the plant
- Stick to the filter change plan
- Store the TR19 paperwork where auditors can find it
When we have closed the unit up, it can be restarted with your site team. Check the drain tray is emptying over the first few days to confirm water is draining away.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.

Where buildings like these have air handling units, filters, coils and drain trays need regular attention. London plant rooms are often on roofs or in basements reached through occupied floors. The nearest hospital to London Fields is German Hospital, about 0.6 miles north-west. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital.
Wherever a school like Gayhurst Community School has ducted ventilation, a half-term visit keeps the work out of lesson time. If you run an office near London Fields station, its supply ductwork can gather dust for years before anyone looks inside.

Multi-site and managed buildings
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.
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.
