AHU cleaning in Kenley, done properly
Our AHU cleans for sites in Kenley cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. Every clean comes with a TR19® certificate and before and after photos in a report. We’re often asked to deal with dust-coated heating and cooling coils and stale or musty smells from the ventilation, on supply and extract fans, drain trays and internal panels.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. In a building in Kenley, dust and debris build up in the units and ductwork over time, which is what TR19® Air cleaning deals with.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

Between visits
How long the results last depends on use and care. We suggest:
- Flag stale or damp smells in the supply air
- Diary the inspection date recommended in the report
- Note any water around the unit or leaks below it
- Change filters on schedule and log each change
You receive a TR19® certificate and a photo report after the clean. They belong in the plant or maintenance log.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
Kenley buildings and their air
Going by the FSA’s register, there are about 18 schools, colleges and universities and about 58 care, childcare and hospital premises serving food in and around Kenley, up to about a mile and a half out. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. For Kenley, the closest hospital is Purley War Memorial Hospital, roughly 1.3 miles north-west. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. Many London buildings have had their ductwork altered through several fit-outs, so an inspection comes first.
Healthcare buildings such as Purley War Memorial Hospital, about 1.3 miles north-west, depend on their ventilation; if you manage a surgery, clinic or care home near Kenley, yours matters too. For schools like Harris Primary Academy Kenley, the holidays are the usual time to inspect and clean ventilation. If you manage shops or offices close to Kenley station, a TR19® Air inspection shows whether the ductwork needs cleaning.

What’s near Kenley
In Kenley, that means kitchens and buildings near Dollypers Hill and Riddlesdown Collegiate and the streets around them. Kenley has its own railway station: Kenley station. A little further out are St George's Walk (3.4 miles north) and Croydon Airport Visitor Centre (2.4 miles north). For a walk, there’s Duppas Hill and Foxley Wood.
What we do, step by step
The visit has three parts: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and photos. The middle part takes longest, which takes one overnight shift for many single units, with bigger plant phased. In Kenley, as across London, we normally work overnight or at weekends and hand the site back ready to open.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Let us know about permits to work or site inductions
- Move anything stored near the system
- Plan for cooking equipment or plant to be off before we arrive
How to get a quote
Getting a quote doesn’t take long. Send a few details and photos, and we typically reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
Advice
Multi-site and managed buildings
We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we will send a fixed quote.
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. Where responsibility is shared, records matter even more.
How we price AHU cleaning
The price is fixed before any work begins. It’s based on:
- The number of sites or systems
- How big the system is
- One-off work versus a regular cycle
- Site requirements such as sign-in and permits
A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. The price is fixed before work begins.
Asking for a quote
Before you ask for a quote, gather:
- Your last certificate, test record or report
- Detail shots of panels, filters and grilles
- A few general shots of the system
- Any symptoms, from odd noises to smells or leaks
For AHU cleaning in Kenley, call 0345 646 2711, or email photos. Let us know the site type and the opening hours, plus pictures or the previous report if they’re to hand. A fixed quote usually follows within one working day.
Kenley questions
Can you clean school ventilation in Kenley during the holidays?
Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 18 schools, colleges and universities with registered kitchens within about a mile and a half of Kenley. Tell us your holiday dates and we will book the visit for when the site is empty.
How do you handle parking and loading in Kenley?
London parking can be tight, so details of loading bays and permits help. Where restrictions apply in the day, an evening or overnight visit normally gets round them.
What do you do with what you remove?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. We do not leave it behind.
Can you clean the ducts connected to the AHU?
Yes. We reach the ducts through access panels, with anything inaccessible recorded, and new panels can be fitted.
Will we get paperwork for the AHU clean?
Yes. A TR19® certificate and photo report are sent after the clean, including anything we think needs attention.
What do you clean inside the unit?
The main parts are the filters, coils, drain tray, fan and inside of the casing. The survey confirms what’s in your unit before we quote.
What types of premises do you cover?
Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.
Is a quote from photos possible?
Yes, for many jobs. Send a few wide pictures plus close-ups of panels, filters or grilles, and a fixed quote normally follows within one working day. Some sites still need a visit, and we will say so.
When something else is needed
Not every problem is solved by AHU cleaning, and we’d rather say so up front. It does not solve:
- Leaking heating or cooling coils
- The supply and extract ducts, quoted separately
- A system that is undersized for the building
If you are not sure, just call 0345 646 2711, or send details by email and we’ll give you a straight answer.
Parts of the system we cover
- Internal panels
- Supply and extract fans
- Heating and cooling coils
- Drain trays
- Filter sections
- Dampers and louvres
Other services in Kenley
Different parts, different methods
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. The intake section gets particular attention.
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. The impeller, its housing and the fan chamber are cleaned.
What your team can do, and what needs us
If your staff spot something 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: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That is our job.
