AHU cleaning for kitchens and businesses in Littleton
Our AHU cleans for sites in Littleton cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. Every clean comes with a TR19® certificate and before and after pictures in a report. If you are dealing with odours coming through the supply air and dirty coils holding back the airflow, we can put it right, from drain trays, dampers and louvres and filter sections onwards.
Somewhere as small as Littleton, ducted ventilation is usually limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

For landlords and multi-site operators
Facilities teams in offices, schools and healthcare sites book us too across Surrey. Work can be phased by floor, building or site around the people who use them.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
Looking after it afterwards
Looking after the system between visits is straightforward, and it helps at the next visit:
- Change filters on schedule and log each change
- Keep the area around the fresh air intake clear
- Keep inspection doors on the unit in good order
- Book the next check in line with the report
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.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.
Different parts, different methods
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. The impeller, its housing and the fan chamber are cleaned.
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. Access is planned during the survey so the quote reflects it.
How the visit works
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes one overnight shift for many single units, with bigger plant phased. Rural roads and tight entrances are worth telling us about before a visit to Littleton.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
How to prepare
- Dig out any earlier paperwork for the system
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Tell us the best time to work, such as after service or at a weekend

FAQs for Littleton
Can you come to Littleton after we close?
Yes, nights and weekends are routine for us. Your customers, staff or residents in Littleton needn’t be disturbed. Just ring 0345 646 2711 or send us an email with your opening times and we will plan around them.
Do you cover smaller places like Littleton?
Yes, we work in villages as well as towns, and Littleton is covered. Let us know about access, parking and anything unusual about getting there when you book.
What is TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t law, but it’s the benchmark.
What about areas you cannot get to?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, which we can install.
How much notice should we give?
That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
Which sectors do you work in?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
What’s included in an AHU 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.
Do you do ventilation duct cleaning too?
Yes. Ductwork is cleaned through access panels, and any sections we cannot reach are noted in the report, with new panels fitted where necessary.
AHU cleaning in Littleton: local notes
Going by the FSA’s register, there are about 6 schools, colleges and universities and about 6 care, childcare and hospital premises serving food in Littleton and the streets around it, up to about 1.5 miles out. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Littleton is about 17 miles from central London, well within the area we cover across London and the South East. The visit is fixed around your opening hours, not ours. Ashford Hospital is the nearest hospital, about 2.3 miles north of Littleton. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
Hospitals such as Ashford Hospital (about 2.3 miles north) show how much a building can rely on clean ventilation, and smaller healthcare sites near Littleton are no different.
Littleton is about 2 miles south of Ashford, in Surrey. Every kind of commercial site in Littleton, we can take on AHU cleaning.

What your team can do, and what needs us
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
Signs you need AHU cleaning in Littleton
Most units live out of sight on roofs, in plant rooms or in ceiling voids, so they’re easy to forget about. Months can pass without anyone looking inside.
If you notice any of these, it’s worth a diagnosis:
- Dirty fans and fan housings
- Debris and leaves in the fresh air intake
- Dirty coils holding back the airflow
- Air handling units with blocked filters
Classrooms and halls at schools such as Littleton CofE Infant School are easiest to work in when pupils are away.

Leave it or put it right?
If people in a building in Littleton complain about stuffy or smelly air, the AHU is worth looking at. Cleaning it deals with the cause rather than the symptom. Somewhere as small as Littleton, losing a kitchen or building to a fault is felt by everyone who uses it.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are not sure what’s needed, phone us on 0345 646 2711 or drop us a line for straight advice and a fixed quote.
