AHU cleaning in Canary Wharf, done properly
Where a building in Canary Wharf has had little more than filter changes, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full clean deals with all of it. Common call-outs are for air handling units with blocked filters and odours coming through the supply air, on dampers and louvres, heating and cooling coils and drain trays.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. For a building in Canary Wharf, dust settles in the units and ducts year after year.
Nothing is signed off by word of mouth: 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. It shows what was done and what, if anything, couldn’t be reached.

Keeping the system healthy
Simple habits between visits make a real difference. We recommend:
- Diary the inspection date recommended in the report
- Make sure condensate is draining away
- Flag stale or damp smells in the supply air
- Note any water around the unit or leaks below it
The report suggests a date for the next inspection or clean, based on what we found. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.
How the visit works
Night work is normal for us. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. The visit itself takes a single shift for a typical unit, longer for large or heavily soiled ones. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Canary Wharf.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
How to prepare
- Make sure someone can let us in and lock up afterwards
- Move anything stored near the system
- Mention any parking or loading restrictions

Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

FAQs for Canary Wharf
Do you do school ventilation cleaning in Canary Wharf in the summer holidays?
Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 56 schools, colleges and universities with registered kitchens within about a mile and a half of Canary Wharf. You can call 0345 646 2711 or email us with the dates the site is empty.
Can parking be tricky for a job in Canary Wharf?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Working overnight, as we often do in London, usually makes it simpler.
Is there a survey before the work?
Yes. Every job is surveyed first, either from photos and details you send or on a site visit. A fixed quote follows.
Can you price the work without visiting?
Often, yes. With good photos, the site type and your last report, we can price many jobs. Where we can’t see enough, we arrange a survey.
Do you work evenings or weekends?
Yes. The clean is planned around when the unit can be switched off. Healthcare and care settings are planned with staff.
How often do AHUs need cleaning?
There’s no single answer; it comes down to the building and the unit. Inspection tells you when cleaning is needed, and the report recommends a next date.
Which parts of an air handling unit do you clean?
Everything inside the unit that air passes over, from the intake and filters through the coils and fan to the outlet. The photo report shows each section before and after.
How much does AHU cleaning cost?
Size, condition, access and working hours all affect the cost. Ask us for a fixed quote, usually ready within one working day.
What we’re called out for in Canary Wharf
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. The intake section and first filters take the brunt, and some travels further into the unit.
These are the problems we see most often:
- Coils clogged with dust and debris
- Air handling units due a clean after building work
- Leaves and litter drawn into the unit
- Dust built up on fan impellers
If you run an office near Canary Wharf station, its supply ductwork can gather dust for years before anyone looks inside.
What your quote should include
- What’s included in the scope, part by part
- Proof of accreditation you can verify
- What happens if part of the system can’t be accessed
- What records you’ll receive afterwards
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, which is why the unit and the ducts are best cleaned together. A building in Canary Wharf may have flats or offices above and alongside, and a fault in the system can affect them too.
A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. You’ll have a fixed price before any work starts.
Why book with us
- CHAS, SafeContractor and ISO 9001
- One number for every site across the South East and London
- A written report with photos after each visit
- Survey first, then a fixed quote

What AHU cleaning looks like in Canary Wharf
Food Standards Agency data includes about 56 schools, colleges and universities, about 42 caring premises (care homes, nurseries and hospitals) and about 12 hotels and B&Bs in Canary Wharf and the streets around it, up to about 1.5 miles out. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Many London buildings have had their ductwork altered through several fit-outs, so an inspection comes first. The nearest hospital to Canary Wharf is Poplar Hospital, about 0.7 miles north-east. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital.
If you run a surgery, dental practice or care home near Canary Wharf, clean ventilation matters as much to you as to a hospital like Poplar Hospital (about 0.7 miles north-east). For schools like Our Lady and St Joseph Catholic Primary School, the holidays are the usual time to inspect and clean ventilation.

Landlords, agents and facilities managers
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
Staff cleaning versus specialist work
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
