AHU cleaning for kitchens and businesses in Coldharbour
We clean air handling units for buildings in Coldharbour and across Greater London, working to TR19® Air, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. Common call-outs are for debris and leaves in the fresh air intake and coils clogged with dust and debris, on filter sections, heating and cooling coils and dampers and louvres.
London buildings tend to keep their plant on the roof or below ground, so work in Coldharbour is often done in the evening or at weekends. Loading and parking are planned with the building first.
A written report with photos follows each visit, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Different parts, different methods
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. Anything like that is recorded with photos.
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. We clean them with care so the fins aren’t damaged.
When it’s something else
We’ll always give you a straight diagnosis, so here’s what this work cannot put right:
- The supply and extract ducts, quoted separately
- Coils that are corroded or leaking and need replacing
- Building management system faults
If in doubt, give us a ring on 0345 646 2711 or drop us a line and we will say what we think.
What the work covers

Landlords, agents and facilities managers
Records are where multi-site compliance often slips. Each visit ends with a dated report and photos, ready to show insurers, fire officers or EHOs.
Whether it’s one building or many, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
What staff can safely do
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That is our job.
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
AHU cleaning in Coldharbour: local notes
Food Standards Agency records list about 46 schools, colleges and universities, about 40 hospitals, care homes and childcare premises and about 14 hotels, B&Bs and guest houses registered as food businesses within 1.5 miles or so of the middle of Coldharbour. 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. Poplar Hospital is the nearest hospital, about 0.6 miles north of Coldharbour. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Healthcare ventilation, from large hospitals like Poplar Hospital (about 0.6 miles north) to small clinics, depends on clean filters, coils and ducts. If you run an office near Canary Wharf station, its supply ductwork can gather dust for years before anyone looks inside. For schools like Woolmore Primary School, the holidays are the usual time to inspect and clean ventilation.
Coldharbour is about 2 miles north of Greenwich, in Greater London. Every kind of commercial site in Coldharbour, we can take on AHU cleaning. We can work out of hours so the site keeps running. Our area takes in 764 places across Greater London, large and small.
Work in E14, SE10 and E22 follows the same survey, fixed quote and written report as everywhere else we cover. We cover sites on Canada Square, Simpson's Road and Amsterdam Road and the roads around them. With the A1206 and A1261 close by, Coldharbour is easy for our technicians to reach at any hour.

We also work in nearby towns such as London (4 miles west), City of Westminster (6 miles west), Marylebone (6 miles west), Kensington (8 miles west), St Pancras (5 miles west) and Shoreditch (3 miles north-west).

Your questions about AHU cleaning in Coldharbour
Do you do school ventilation cleaning in Coldharbour in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 46 schools and colleges with food registrations within roughly a mile and a half of Coldharbour. Send us your term dates when you call us on 0345 646 2711, or send details by email, and we will fit the work in.
Does London parking affect a job in Coldharbour?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Working overnight, as we often do in London, typically makes it simpler.
What do you do with what you remove?
We take it away at the end of the visit. During the work, it’s contained to keep the area clean.
Will the ventilation be off while you clean?
Yes. The fan must be stopped and the unit isolated, and we time the work to suit the site.
Can you clean the ducts connected to the AHU?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. Cleaning the unit and ducts together often makes sense, and we can quote for both.
Can you set up regular visits?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. Each report recommends when the next visit should be.
What’s included in an AHU clean?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. What happens to the filters is agreed when we quote.
Do you survey before quoting?
Yes. Photos often do the job, and larger or hidden systems get a visit.

Keeping the system healthy
Results last longer with the right care. We suggest:
- Keep inspection doors on the unit in good order
- Stick to the filter change plan
- Clear leaves and litter away from the intake
- Report water on the plant room floor
We recommend when the unit should next be inspected or cleaned, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
How it works
Your staff do not need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Afterwards, the area is left tidy and the written report follows. Getting kit into a London building takes planning, so let us know where we can load and park in Coldharbour.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Tell us the best time to work, such as after service or at a weekend
- Make sure equipment near the work can be switched off and left to cool
- Make sure someone can let us in and lock up afterwards
Ask for a quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.
Advice
What happens if it’s left?
A light clean now is simpler than a heavy one later. Years of build-up make the job longer and harder, particularly where damp has made it stick. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.
