AHU cleaning for kitchens and businesses in Ashdon
Our AHU cleans for sites in Ashdon cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. Typical jobs include leaves and litter drawn into the unit and dirty filters cutting the airflow, on dampers and louvres, internal panels and drain trays.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
A written report with photos 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.

Leave it or put it right?
A slimy drain tray only gets worse. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Clearing it now is a much smaller job. A planned visit to Ashdon is easier to arrange than an emergency callout.
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we will explain each part.

What staff can safely do
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’ll take a look and send you a fixed quote.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
What affects the cost of AHU cleaning
We quote each job individually. These are the things that affect it:
- Where the site is and how we reach it
- A single visit or a regular plan
- The condition we find in the survey
- Whether we need access equipment or extra panels
One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. The price is fixed before work begins.
What to send for a quote
Photos let us diagnose from a distance. Try to include:
- The postcode and the type of business
- Photos showing the whole system and its surroundings
- Your last certificate, test record or report
- The roof, plant room or outside wall the system runs to
For AHU cleaning in Ashdon, call us on 0345 646 2711 or send us an email. Tell us what kind of premises it is and when it’s open, and send photos or your last report if you can. A fixed quote usually follows within one working day.
How it 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 pictures. The middle part takes longest, and that takes anything from half a day for one small unit to several shifts for a plant room full of them. Visits to a village like Ashdon are booked in advance, at a time that suits whoever runs the site.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
Getting ready for the visit
- Let us know about permits to work or site inductions
- Make sure equipment near the work can be switched off and left to cool
- Mention any locked doors, roof access or ceiling voids
How to get a quote
Getting a quote doesn’t take long. Call or email with a few details and you’ll typically have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.

When to call us in Ashdon
Filters that aren’t changed or cleaned on time clog up, which cuts the airflow and can let air slip round the filter. After that, the coils and fan collect what the filter should have caught.
Clients typically contact us when they notice something like this:
- Leaves and litter drawn into the unit
- Odours coming through the supply air
- Dust built up on fan impellers
- Blocked condensate drains and slimy trays
For schools like Ashdon Primary School, the holidays are the usual time to inspect and clean ventilation.
Before you book anyone
- Whether the figure could change on the day
- If they look at the system before pricing
- Whether they’re fully insured
- When they can work, and whether that’s outside your opening hours
What the work involves, part by part
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. They’re cleaned using methods that will not bend or flatten the fins.
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. Each section is cleaned from the intake through to the outlet.
When it’s something else
A few issues sit outside what this work can do:
- Damaged coils beyond cleaning
- Faulty motors, drives or bearings
- A system that is undersized for the building
If you’re not sure, just call us on 0345 646 2711 or email us and we will give you a straight answer.
Parts of the system we cover

Questions from Ashdon
Can a school’s ventilation in Ashdon be done out of term time?
Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 3 schools, colleges and universities with registered kitchens within about a mile and a half of Ashdon. Send us your term dates when you call us on 0345 646 2711 or email us, and we’ll fit the work in.
Do you work in villages like Ashdon?
Yes, we work in villages as well as towns, and Ashdon is covered. A survey first, from pictures or a visit, means we arrive with the right kit.
What if parts of the system can’t be reached?
They’re marked on the report. In ductwork, new access panels are often the answer, and we can fit those.
Which kinds of sites do you work on?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
How long does it take to clean an air handling unit?
Expect it to take anything from half a day for one small unit to several shifts for a plant room full of them. The unit’s size and condition make the biggest difference, and the quote will give you a clear idea.
Which parts of an air handling unit do you clean?
Everything inside the unit that air passes over, from the intake and filters through the coils and fan to the outlet. The photo report shows each section before and after.
Are you fully insured?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
Do you do ventilation duct cleaning too?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. It’s often worth doing both at once, and we can survey both on the same visit.
