AHU Cleaning in Wallingford
One call covers AHU cleaning in Wallingford, from survey to sign-off. Fully insured, with CHAS, SafeContractor and ISO 9001.
- Dirty coils holding back the airflow
- Filters that are clogged or overdue
- Intake sections clogged with outdoor debris
Staff cleaning versus specialist work
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That’s our job.
AHU cleaning for kitchens and businesses in Wallingford
Our AHU cleaning covers sites in Wallingford and the rest of Oxfordshire, in offices, schools, hospitals, care homes and retail. The work is timed around when the system can be switched off, including evenings, nights and weekends. If you have units that have only ever had filter changes and stale or musty smells from the ventilation, we can put it right, from supply and extract fans, internal panels and heating and cooling coils onwards.
Smaller buildings around Wallingford often keep their ventilation units in a roof void or plant cupboard, where they’re easy to forget. Filters, coils and drain trays need attention whatever the size of the unit.
Nothing is signed off by word of mouth: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

What AHU cleaning looks like in Wallingford
Going by the FSA’s register, there are about 3 schools, colleges and universities, about 7 care, childcare and hospital premises and about 3 hotels and guest houses serving food within roughly a mile and a half of the centre of Wallingford. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. At about 45 miles from central London, Wallingford sits well inside the area we cover. Visits are booked around your hours, evenings and weekends included.
Wherever a school like Fir Tree Junior School has ducted ventilation, a half-term visit keeps the work out of lesson time. An inspection comes first for any ventilation job around Wallingford, so the cleaning matches what’s there.

Keeping the system healthy
Aftercare is simple, and it makes the next visit easier:
- Keep filter changes on time and recorded
- Do not ignore odours coming through the grilles
- Keep the certificate and photo report with the plant records
- Look at the condensate drain whenever the unit is serviced
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Record each change in the maintenance log.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.
Multi-site and managed buildings
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
Facilities teams in offices, schools and healthcare sites book us too across Oxfordshire. Larger estates can be phased building by building to keep disruption down.
What affects the cost of AHU cleaning
Before we fix a price, we need to know a few things. We check:
- When the work can happen, such as evenings, overnight or weekends
- Access, including roofs, risers and ceiling voids
- Any permits to work or inductions
- The condition we find in the survey
A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. The price is fixed before we start.
What to send for a quote
To speed up the quote, please include:
- Close-ups of filters, grilles, hatches or access panels
- The times we could work without disrupting the site
- How we’d reach plant on a roof or in a plant room
- Anything you’ve noticed, such as smells, noise, drips or poor airflow

How it works
The visit has three parts: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with photos. Most of the time goes on the work itself, which takes half a day to a full day per unit, with large plant planned over several shifts. A site near Wallingford normally has room to park, so the questions are about access to the system and your hours.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Before we arrive
- Arrange a key holder or contact on site
- Plan for cooking equipment or plant to be off before we arrive
- Tell us about site rules, permits or sign-in

Your questions about AHU cleaning in Wallingford
Do you do school ventilation cleaning in Wallingford in the summer holidays?
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 Wallingford. Send us your term dates when you give us a ring on 0345 646 2711 or email us, and we’ll fit the work in.
Do you cover smaller places like Wallingford?
Yes. Villages and rural sites across the South East are part of our work, Wallingford included. The journey is planned ahead, so a few details about the route help.
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 quote for both.
Do you offer maintenance contracts?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. Each report recommends when the next visit should be.
How much does AHU cleaning cost in Wallingford?
Size, condition, access and working hours all affect the cost. Call for a fixed quote, usually ready within one working day.
What if parts of the system can’t be reached?
We never leave them off the paperwork. You’ll know exactly which parts weren’t reached and why, and we can quote to improve the access.
What is TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
How often should an air handling unit be cleaned?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. We recommend a next date in each report.
When it’s something else
Not every problem is solved by AHU cleaning, and we’ll tell you before we start. It will not put right:
- Breakdowns that need a mechanical engineer
- Leaking heating or cooling coils
- Dirty ducts beyond the unit itself
If in doubt, call us on 0345 646 2711, or send details by email and we will say what we think before booking.
Parts of the system we cover
- Drain trays
- Dampers and louvres
- Internal panels
- Heating and cooling coils
- Filter sections
- Supply and extract fans
Leave it or put it right?
Stuffy rooms and stale smells in a building in Wallingford can sometimes be traced back to the AHU. A clean tackles the source instead of masking it. A site near Wallingford that has to close at short notice is hard to cover for.
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered and we’ll price it together.
