Spitalfields AHU cleaning
Our technicians work in Spitalfields on cleaning of air handling units, including filters, coils, drain trays, fans and internal surfaces. Out-of-hours visits, a fixed quote and a written report with pictures on every job.
- Leaves and litter drawn into the unit
- Units that have only ever had filter changes
- Dust-coated heating and cooling coils
How we handle AHU cleaning in Spitalfields
Where a building in Spitalfields has had little more than filter changes, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full AHU clean takes in the whole unit. If you are dealing with dirty fans and fan housings and leaves and litter drawn into the unit, we can help, from supply and extract fans, internal panels and heating and cooling coils onwards.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so ventilation cleaning in Spitalfields is normally planned out of hours. Loading and parking are planned with the building first.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

When to call us in Spitalfields
Filters that aren’t changed or cleaned on time clog up, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
Signs it’s time to call us include:
- Intake sections clogged with outdoor debris
- Dirty filters cutting the airflow
- Odours coming through the supply air
- Dirty fans and fan housings
If you manage shops or offices close to London Liverpool Street station, a TR19® Air inspection shows whether the ductwork needs cleaning.
Questions to ask before booking
- Whether the quote is based on a survey or pictures
- When they can work, and whether that is outside your opening hours
- How VAT is shown on the quote
- Whether inaccessible sections are listed on the report
What we do, step by step
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool before we start, and floors and nearby surfaces are sheeted. The work itself takes anything from half a day for one small unit to several shifts for a plant room full of them. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Spitalfields.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- After photos are taken and the certificate issued.
Getting ready for the visit
- Allow time for equipment near the work to be turned off and cool down
- Clear loose items from the work area
- Name a contact who can let us in at the agreed time

Ventilation in Spitalfields buildings
There are about 96 schools, colleges and universities, about 64 hospitals, care homes and childcare premises and about 75 hotels and guest houses on the FSA’s food hygiene register across Spitalfields and its immediate surroundings (about a mile and a half). Where buildings like these have air handling units, filters, coils and drain trays need regular attention. Spitalfields’s nearest hospital, The Royal London Hospital, is about 0.7 miles east. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. Ventilation cleaning in London buildings is typically planned for evenings or weekends.
Healthcare ventilation, from large hospitals like The Royal London Hospital (about 0.7 miles east) to small clinics, depends on clean filters, coils and ducts. School buildings such as Makers Academy are normally done in the holidays, so classrooms are not disturbed.
Spitalfields is about 1 mile north-east of London, in Greater London. Whether your site is in the middle of Spitalfields or further out, we cover AHU cleaning for every kind of premises, from a single unit to a large public building. Our Greater London coverage runs to 764 places, and Spitalfields is one of them.
Work in E1, EC2A and E1W is surveyed, quoted and booked the same way as anywhere else. If you need AHU cleaning at premises on New Road, Mark Lane and Bell Lane or a nearby road, our technicians can take on the work. Spitalfields is on the A10 and A1202, which makes it straightforward for our technicians to reach for out-of-hours visits. We also cover Whitechapel (1 mile east), Aldgate (1 mile south-west), Bishopsgate (1 mile west), Tower Hill (1 mile south) and Shoreditch (1 mile north). Within a short drive, we also cover City of Westminster (3 miles west), Marylebone (3 miles west), Kensington (6 miles west), Walthamstow (5 miles north-east), Hampstead (5 miles north-west) and Ruislip (15 miles west).
Local landmarks in Spitalfields
We work in commercial kitchens and buildings around Finsbury Circus, Bishopsgate Institute Special Collections and Archives and Canon Barnett Primary School. Nearby too are St Mary-at-Hill (0.6 miles south-west), London Enterprise Academy (0.5 miles east) and Kings Stores pub (less than half a mile north-west). There’s a railway station in Spitalfields itself: London Liverpool Street station. Well-known places in the area include Tower of London (0.6 miles south) and Gabriel's Wharf (1.5 miles west). For a walk, there’s Tower Hill and Lavender Pond.

What AHU cleaning can’t fix
AHU cleaning can’t fix everything, and we’ll tell you before work begins. It does not solve:
- Ductwork downstream of the unit, which is a separate clean
- Mechanical faults with motors, belts or bearings
- Leaking heating or cooling coils
If in doubt, phone us on 0345 646 2711 or email us and we will say what we think before you book.
Where we work
- Dampers and louvres
- Heating and cooling coils
- Filter sections
- Drain trays
- Internal panels
- Supply and extract fans
Fixed quotes for AHU cleaning in Spitalfields
Sites vary more than people expect. What affects the quote:
- Whether it’s a one-off visit or part of a schedule
- When the work can happen, such as evenings, overnight or weekends
- The condition of the system
- Any permits to work or inductions
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’ll go through it with you.
What to send for a quote
You don’t need the technical terms. Just send:
- The roof, plant room or outside wall the system runs to
- Your last certificate, test record or report
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- A few general shots of the system
To get a fixed quote, call 0345 646 2711 or send us an email with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. We typically come back within one working day.
Questions from Spitalfields
Does London parking affect a job in Spitalfields?
Tell us where a van can stop near your site in Spitalfields, and about any building rules on loading. Where restrictions apply in the day, an evening or overnight visit normally gets round them.
Do you work at weekends in Spitalfields?
Yes, out-of-hours work is a big part of what we do. The work in Spitalfields can fit around your hours. When you phone us on 0345 646 2711 or email us, mention when the site is quiet.
How far ahead should we book?
The more notice, the better, especially for out-of-hours work. We normally quote within one working day, and emergencies are covered by our 24/7 line.
What do you do with what you remove?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. None of it is left on site.
How much does AHU cleaning cost?
Size, condition, access and working hours all affect the cost. Call for a fixed quote, typically ready within one working day.
What do you clean inside the unit?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. What happens to the filters is agreed when we quote.
Are you insured?
Yes. We are fully insured, and the details are available on request.
What about areas you cannot get to?
We record them on the report, with photos where possible, and we explain what access is needed, for example new access panels.
What happens if it’s left?
Leave an AHU uncleaned and the dirt does not stay put. It moves on into the ductwork and out into the rooms, so cleaning the ducts without the unit only goes so far. London buildings are shared, so a fire or failure in one system can reach the neighbours above and beside you.
What you pay depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before we start, so you know where you stand.

In-house cleaning or a specialist?
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. 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. That’s our job.
How the job changes from site to site
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. Cleaning keeps it running as intended.
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. Each section is cleaned from the intake through to the outlet.
