How the visit works
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before any work starts, and floors and nearby surfaces are sheeted. The work itself takes from a few hours for a compact unit to a day or more for a large one. Photos of the system and how to reach it help us plan a visit to Wicken Bonhunt.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before photos of each section of the unit.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- We take after pictures and issue the certificate and report.
Preparing for the visit
- Make sure equipment near the work can be switched off and left to cool
- Find the previous report, if there is one
- Let us know how we reach the system, including roofs, risers and plant rooms

AHU cleaning in Wicken Bonhunt, done properly
An AHU clean is a thorough examination and treatment of the unit. We look inside each section, clean what we find and record it with photos, so the report shows exactly what was done. Common call-outs are for odours coming through the supply air and fan sections that haven’t been cleaned in years, on heating and cooling coils, dampers and louvres and supply and extract fans.
In a village or hamlet like Wicken Bonhunt, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Every visit ends with a written report and pictures, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Questions from Wicken Bonhunt
Can the work in Wicken Bonhunt be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. It means the site in Wicken Bonhunt keeps running as normal. Just call us on 0345 646 2711 or send us an email with your opening times and we’ll plan around them.
Can you clean school ventilation in Wicken Bonhunt during the holidays?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 3 schools and colleges with food registrations within roughly a mile and a half of Wicken Bonhunt. Just call us on 0345 646 2711 or email us with your term dates and we will plan around them.
How much notice should we give?
The more notice, the better, especially for out-of-hours work. Quotes normally come back within one working day, and emergencies are covered by our 24/7 line.
What types of premises do you cover?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
Are you fully insured?
Yes, we’re fully insured. We also hold CHAS and SafeContractor, for sites that check contractor safety.
Do you do ventilation duct cleaning too?
Yes. We clean supply and extract ductwork to TR19® Air as well. Cleaning the unit and ducts together often makes sense, and we can survey both on the same visit.
When should our AHU next be cleaned?
Inspection under TR19® Air decides it. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
Do you offer maintenance contracts?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. The report from each visit recommends the next date.
How we price AHU cleaning
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether several sites go on one quote
- Access, including roofs, risers and ceiling voids
- Whether it’s a one-off visit or part of a schedule
- Parking and loading at the site
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at, and you’ll get one fixed quote.
What to send for a quote
Photos and a few facts are often enough to price the work. Useful things to send:
- The postcode and the type of business
- Detail shots of panels, filters and grilles
- Your opening hours and when the area is out of use
- The roof, plant room or outside wall the system runs to
Quotes are quick. Call or email with a few details and you’ll typically have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
In-house cleaning or a specialist?
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.

Aftercare tips
Once we have finished, these simple steps help:
- Report musty smells from the vents straight away
- Clear leaves and litter away from the intake
- Report stiff or damaged access doors
- Keep the certificate and photo report with the plant records
Stick to the filter change schedule, because good filters protect everything downstream. Record each change in the maintenance log.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
When to call us in Wicken Bonhunt
Planned maintenance often covers belts, motors and filters but not cleaning. That means a unit can tick every service box and still be carrying years of dirt.
Most sites get in touch when they notice something like this:
- Rooms that smell stuffy when the system runs
- Blocked condensate drains and slimy trays
- Intake sections clogged with outdoor debris
- Dust-coated heating and cooling coils
If you manage a school such as Joyce Frankland Academy, ventilation cleaning is best booked for the holidays.
Before you book anyone
- Whether the whole system is included, or only the parts that are easy to reach
- Whether the figure could change on the day
- Proof of accreditation you can verify
- Whether VAT is included
What the work involves, part by part
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. The coil and its drain tray are cleaned as one job.
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. We note any we find in the report.
