AHU cleaning for kitchens and businesses in Gillette Corner
We clean the parts of the unit where dirt and moisture gather: filters, coils, drain trays, fans and the internal panels. Every clean comes with a TR19® certificate and before and after pictures in a report. The work covers drain trays, filter sections and internal panels, and the jobs we see most are leaves and litter drawn into the unit and dirty filters cutting the airflow.
London buildings tend to keep their plant on the roof or below ground, so work in Gillette Corner is often done in the evening or at weekends. Parking and loading are agreed with the building in advance.
A written report with photos follows each visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

What happens if it’s left?
A light clean now is simpler than a heavy one later. Leave it for years and dirt bakes onto coils and casings, especially where there’s been moisture. Planning ahead in Gillette Corner lets you pick a quiet night rather than lose a busy one.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re not sure what’s needed, give us a ring on 0345 646 2711 or drop us a line for straight advice and a fixed quote.

Aftercare tips
After the visit, a few habits help the work last:
- Make sure the unit’s access doors open easily
- Do not ignore odours coming through the grilles
- Do not store bins or materials near the intake
- Make sure condensate is draining away
Restart the unit with your site team or maintenance contractor once we have finished. Keep an eye on the condensate drain over the next few days to confirm water is draining away.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
Landlords, agents and facilities managers
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so each one has its own record.
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
What AHU cleaning looks like in Gillette Corner
The FSA’s food hygiene register lists about 32 schools, colleges and universities, about 46 caring premises (care homes, nurseries and hospitals) and about 9 hotels, B&Bs and guest houses with registered kitchens or food service across Gillette Corner and its immediate surroundings (about a mile and a half). Buildings like these often rely on mechanical ventilation, which TR19® Air covers. In London, ventilation plant is often on the roof or below ground, so the work is normally done out of hours. For Gillette Corner, the closest hospital is West Middlesex University Hospital, roughly 0.7 miles south. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
Workplaces around Syon Lane station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts. Classrooms and halls at schools such as Marlborough Primary School are easiest to work in when pupils are away.

Around Gillette Corner
In Gillette Corner, that means kitchens and buildings near The Green School, Coach and Horses pub and Boston Manor Park, among other places.

What we’re called out for in Gillette Corner
Mechanical servicing keeps a unit running, but it doesn’t always include cleaning the inside. That means a unit can tick every service box and still be carrying years of dirt.
Any of these means the system needs a check-up:
- Blocked condensate drains and slimy trays
- Units that have only ever had filter changes
- Plant that needs cleaning after a refit
- Filters that are clogged or overdue
If you run a surgery, dental practice or care home near Gillette Corner, clean ventilation matters as much to you as to a hospital like West Middlesex University Hospital (about 0.7 miles south).

What we do, step by step
There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. Most of the time goes on the work itself, and that takes half a day to a full day per unit, with large plant planned over several shifts. Before any visit in Gillette Corner, we agree where the van can stop and how equipment reaches the system.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- 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
- Mention any parking or loading restrictions
- Have your last certificate or report to hand
- Mention any locked doors, roof access or ceiling voids
Getting a quote

Advice
Staff cleaning versus specialist work
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We will take a look and send you a fixed quote.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Gillette Corner: your questions answered
How do you handle parking and loading in Gillette Corner?

How do you keep the site clean during the work?
Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
Do you work evenings or weekends?
Yes. The clean is planned around when the unit can be switched off. In hospitals and care homes, we agree timings with the site team.
What does TR19 mean?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not legislation, but it’s the standard people check against.
How much does AHU cleaning cost?

Do you clean the ductwork as well?
Yes, supply and extract ducts, grilles and diffusers. We’ll tell you after the survey whether the ducts need it.

What the work involves, part by part
Drain trays
The drain tray collects water from the cooling coil. We clear standing water, clean out slime and check the outlet is draining.
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. We plan safe access as part of the survey so the quote reflects it.
