AHU cleaning for kitchens and businesses in Cold Harbour
Our AHU cleaning covers sites in Cold Harbour and the rest of Kent, in buildings such as offices, schools, healthcare sites and shops. The work is timed around when the system can be switched off, including evenings, nights and weekends. Typical jobs include dirty coils holding back the airflow and stale or musty smells from the ventilation, on drain trays, filter sections and supply and extract fans.
Work in a small place like Cold Harbour starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What happens on the day
We are used to working while the site is closed. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. The visit itself takes half a day to a full day per unit, with large plant planned over several shifts. If the van will struggle with a lane or gateway near Cold Harbour, let us know and we’ll plan around it.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Tell us about site rules, permits or sign-in
- Clear loose items from the work area
- Find the previous report, if there is one
Getting a quote
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. Then we send a fixed price so you know the cost before any work starts.
Advice
What AHU cleaning cannot fix
Some problems need a different service or another trade:
- Damaged coils beyond cleaning
- Problems with the unit’s controls or sensors
- Ventilation that was badly designed in the first place
If you’re not sure, just ring 0345 646 2711, or send details by email and we’ll give you a straight answer.

Questions from Cold Harbour
Can you get to a site in Cold Harbour?
Yes, smaller places are covered as well as towns. A survey first, from pictures or a visit, means we arrive with the right kit.
Can you do AHU cleaning in Cold Harbour?
Yes. We work across London and the South East, and Cold Harbour is part of that. Just call us on 0345 646 2711 or send us an email with a few details of the site.
Can you price the work without visiting?
Yes, for many jobs. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote usually follows within one working day. Some sites still need a visit, and we will say so.
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.
Can you come out in an emergency?
Yes. There’s a 24/7 emergency line for anything that cannot wait until a planned visit. Call us any time and explain what’s happened.
What do you do with what you remove?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on, so it doesn’t spread.
Are you insured?
Yes, we are fully insured. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
Will you repair the fan or motor?
We clean the unit and flag faults rather than repair them, with the details in the report.
Keeping the system healthy
No system stays clean for ever, but care slows the build-up. A few tips:
- Book the next check in line with the report
- Keep filter changes on time and recorded
- Report stiff or damaged access doors
- File each AHU report in the maintenance log
The report suggests a date for the next inspection or clean, taking into account how dirty it was. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
Why it’s worth doing now in Cold Harbour
If people in a building in Cold Harbour complain about stuffy or smelly air, the AHU is worth looking at. Cleaning it deals with the cause rather than the symptom. A planned visit to Cold Harbour is easier to arrange than an emergency callout.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you are not sure what’s needed, call us on 0345 646 2711, or email photos and we’ll give you an honest view and a fixed quote.
What you get with us
- CHAS and SafeContractor accredited, with ISO 9001
- A fixed price before any work starts
- A single point of contact for sites across the South East and London
- A written report with photos after each visit

What we are called out for in Cold Harbour
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.
The symptoms we are asked about most include:
- Rooms that smell stuffy when the system runs
- Fan sections that haven’t been cleaned in years
- Air handling units never cleaned inside
- Drain trays holding standing water
In Cold Harbour, supply and extract ducts are cleaned along with the units that serve them.
What to look for in a quote

How the job changes from site to site
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. The intake section gets particular attention.
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. A clean fan runs more smoothly.
Multi-site and managed buildings
From a single site to a large estate, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
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.
