AHU cleaning for kitchens and businesses in Fox
Units vary a lot in size, age and layout, whether it’s a compact unit in a ceiling void or a big unit on the roof. Every job starts with a survey, from photos or on site, followed by a fixed quote, so you know where you stand. We are often asked to deal with drain trays holding standing water and air handling units never cleaned inside, on drain trays, supply and extract fans and filter sections.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
The sign-off is always in writing: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

What staff can safely do
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
How the job changes from site to site
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. Anything like that is recorded with photos.
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. The space underneath is protected with sheeting first.
Common questions in Fox
Can you come to Fox after we close?
Yes, we can come after you close and finish before you open. That way a site in Fox doesn’t have to lose a day’s trading. Just call us on 0345 646 2711, or send details by email with your opening times and we’ll plan around them.
Will you come out to Fox?
Yes. Villages and rural sites across the South East are part of our work, Fox included. The journey is planned ahead, so a few details about the route help.
What information do you need?
The site address, the type of premises and your opening hours, along with a few pictures and any previous report.
What if parts of the system can’t be reached?
They’re listed in the report, never skipped quietly. You’ll know exactly which parts weren’t reached and why, and we can quote to improve the access.
How long does an AHU clean take?
Expect it to take a single shift for a typical unit, longer for large or heavily soiled ones. The unit’s size and condition make the biggest difference, and we will confirm the time when we quote.
Do you work with multi-site operators?
Yes. Tell us the addresses and what each needs and you will get one fixed quote.
Where does the waste go?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. We do not leave it behind.
Do you give a certificate after the clean?
Yes, a TR19® certificate and a photo report. It includes a recommended date for the next check.
What affects the cost of AHU cleaning
Some jobs are bigger than they look, and some smaller. The main factors:
- Access, including roofs, risers and ceiling voids
- How big the system is
- Working hours and out-of-hours timing
- Travel, parking and unloading
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote, and the price is fixed before any work starts.
Asking for a quote
We can often survey from photos. The most useful are:
- Any previous report or certificate
- Problems your staff have spotted
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Close-ups of filters, grilles, hatches or access panels
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before we start.
How the visit works
The visit has three parts: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with photos. The middle part takes longest, which takes a single shift for a typical unit, longer for large or heavily soiled ones. Somewhere as small as Fox, the date and timings are agreed with you well before the day.
- We survey the unit from photos or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Standing water and slime come out of the tray and the drain is checked.
- A TR19® certificate and photo report follow the clean.
How to prepare
- Tell us where we can park and unload
- Make sure someone can let us in and lock up afterwards
- Plan for cooking equipment or plant to be off before we arrive
Ask for a quote
Every quote begins with a look at the system, from your photos and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work so you know the cost before any work starts.
Related advice
Keeping the system healthy
So the system stays in good health:
- Do not ignore odours coming through the grilles
- Clear leaves and litter away from the intake
- Book the next check in line with the report
- Store the TR19 paperwork where auditors can find it
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.
Don’t let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
