How we handle AHU cleaning in Churchill
All the building’s air passes through the fan, so dust on its blades and housing ends up in the airstream. Fan, housing and the surrounding panels are cleaned as part of the job, with the unit switched off and made safe first. We’re often asked to deal with units that have only ever had filter changes and filters that are clogged or overdue, on drain trays, filter sections and dampers and louvres.
For a building in or near Churchill, access is agreed in advance and the visit is planned around the journey.
A written report with pictures follows every visit, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

FAQs for Churchill
Do you work at weekends in Churchill?
Yes, nights and weekends are routine for us. That way a site in Churchill doesn’t have to lose a day’s trading. Your opening times are the first thing we ask for.
Do you clean school ventilation in Churchill in the holidays?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 2 schools, colleges and universities with registered kitchens within about a mile and a half of Churchill. Booking early in the term gives the best choice of holiday dates.
Is a quote from pictures possible?
Yes, where the pictures show enough. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
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 often do AHUs need cleaning?
There’s no single answer; it comes down to the building and the unit. Regular inspection shows when it’s due, and we’ll suggest an interval after the first clean.
How much does AHU cleaning cost in Churchill?
We do not publish prices, because the cost depends on the job: the size of the system, its condition, access and when we can work. We fix the price before work begins.
Can one contract cover all our sites?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together as one programme. Each site gets its own report and pictures.
Does the AHU have to be shut down for cleaning?
Yes, for the time we are working on it. We can work evenings, overnight or at weekends so the building isn’t left without ventilation when it’s busy.
What the work involves, part by part
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. We clean them with care so the fins aren’t damaged.
Filters
What’s on the filters is a good clue to what’s further in. They’re photographed before and after for your records.
How we price AHU cleaning
The price is fixed before any work begins. It takes into account:
- When the work can happen, such as evenings, overnight or weekends
- Travel, parking and unloading
- Access, including roofs, risers and ceiling voids
- The scale of the work
The cost depends on how big the system is, the condition it’s in and how easy it is to reach. We give you a fixed price before any work starts, so there are no surprises.
Helping us quote
Many jobs can be priced from pictures and some basics. Useful things to send:
- A few general shots of the system
- When the site is open and when it’s quiet
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Problems your staff have spotted
For a fixed quote, phone us on 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. A few photos and your last certificate or report help a lot. We typically come back within one working day.
What your team can do, and what needs us
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
What we do, step by step
Protection comes first: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes one overnight shift for many single units, with bigger plant phased, and we clear up before we go. Visits to a village like Churchill are booked in advance, at a time that suits whoever runs the site.
- 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.
Getting ready for the visit
- Let us know when the site is closed or quiet
- Let us know how we reach the system, including roofs, risers and plant rooms
- Mention any parking or loading restrictions

What AHU cleaning can’t fix
We will always give you a straight diagnosis, so here’s what AHU cleaning will not do:
- Problems with the unit’s controls or sensors
- Faulty motors, drives or bearings
- The supply and extract ducts, quoted separately
If you are not sure, just phone us on 0345 646 2711, or email photos and we will give you a straight answer before you book.
Where we work
- Filter sections
- Supply and extract fans
- Dampers and louvres
- Drain trays
- Heating and cooling coils
- Internal panels
Keeping the system healthy
Results last longer with the right care. We suggest:
- Plan the next inspection before the last report gets filed away
- Do not store bins or materials near the intake
- Report stiff or damaged access doors
- Keep filter changes on time and recorded
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Log every change so it’s easy to see when the next is due.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.
Common problems we fix in Churchill
No filter stops everything. What gets through settles on coils, fans and the inside of the casing, a little more each month.
What we are most often called out for:
- Units needing a clean before a new tenant or handover
- Filters that are clogged or overdue
- Stale or musty smells from the ventilation
- Intake sections clogged with outdoor debris
Wherever a school like Kingham Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
