Questions from Mile End
Can ventilation in schools around Mile End be cleaned out of term?
Yes. Half-terms and the summer break are the natural time for school work. Around Mile End, the Food Standards Agency lists about 84 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we will book the visit for when the site is empty.
Is parking a problem for work in Mile End?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Much of our London work is done overnight, which helps.
How much does AHU cleaning cost in Mile End?
Size, condition, access and working hours all affect the cost. Ask us for a fixed quote and we will usually reply within one working day.
What does TR19 mean?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
Which accreditations do you hold?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.
What if parts of the system cannot be reached?
Anything we cannot reach goes on the report, with photos where possible, and we tell you what would make it reachable, for example new access panels.
What information do you need?
A short description and a few photos, with the address and opening hours. We will ask for anything else we need.
How do you protect the area?
By covering it before any work starts. The work is kept contained and leave the area clean.
About our AHU cleaning in Mile End
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. Common call-outs are for dirty coils holding back the airflow and fan sections that haven’t been cleaned in years, on supply and extract fans, heating and cooling coils and internal panels.
London offices and flats often have ductwork added through successive refits, leaving sections that are hard to reach and seldom cleaned. An inspection first shows where cleaning is needed in a building in Mile End.
Think of the report as the system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

The process
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. The visit takes from a few hours for a compact unit to a day or more for a large one. Before any visit in Mile End, we agree where the van can stop and how equipment reaches the system.
- We agree a shutdown window that suits the building.
- We take before photos 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.
- After photos are taken and the certificate issued.

Advice
Mile End buildings and their air
Food Standards Agency data includes about 84 schools, colleges and universities, about 46 care, childcare and hospital premises and about 12 hotels and guest houses in and around Mile End, up to about a mile and a half out. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Mile End’s nearest hospital, St Clement's Hospital, is about under half a mile north-east. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes. Getting kit to a London plant room usually means lifts, stairs and an agreed loading slot.
Healthcare buildings such as St Clement's Hospital, about under half a mile north-east, depend on their ventilation; if you manage a surgery, clinic or care home near Mile End, yours matters too. For schools like Beatrice Tate School, the holidays are the usual time to inspect and clean ventilation.

What happens if it’s left?
Standing water in a drain tray does not clear itself. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Clearing it now is a much smaller job. It’s better booked as a planned job in Mile End than handled as an emergency.
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’re not sure what’s needed, phone us on 0345 646 2711 or send us an email and we’ll give you an honest view and a fixed quote.

Staff cleaning versus specialist work
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
Aftercare tips
Aftercare is simple, and it makes the next visit easier:
- Make sure the unit’s access doors open easily
- Look at the condensate drain whenever the unit is serviced
- Change filters on schedule and log each change
- Store the TR19 paperwork where auditors can find it
The report shows each section of the unit before and after, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Make the drain tray part of every maintenance visit. A drain that is cleared early never gets to the slime stage.
Part by part
Drain trays
Older trays can corrode and start leaking. Their condition goes into the report with photos so you can decide on any repairs.
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. Cleaning keeps it running as intended.
What we’re called out for in Mile End
It matters for two reasons: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For the people using the building every day, that’s the air they breathe for hours on end.

- Odours coming through the supply air
- Air handling units never cleaned inside
- Blocked condensate drains and slimy trays
- Air handling units due a clean after building work
