What affects the cost of AHU cleaning
There’s no set price list, because no two systems are the same. What we look at:
- How many systems or sites are involved
- A single visit or a regular plan
- How big the system is
- How easy every part is to reach
We do not list prices on the website, because each job is priced on what it involves. For a fixed quote, give us a ring on 0345 646 2711 or email us, and we will talk you through it.
What to send for a quote
We can often survey from photos. The most useful are:
- When the site is open and when it’s quiet
- A few general shots of the system
- The site address and the type of premises
- Where the plant sits or the system leaves the building, such as a roof or outside wall
Quoting starts with a diagnosis, from your photos and details or, where that is not enough, a survey on site. Then we send a fixed price so you know the cost before any work starts.
AHU cleaning for kitchens and businesses in Troy Town
An air handling unit is the heart of a building’s ventilation: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Anything that collects inside the unit can end up in the rooms it serves, so cleaning the unit matters as much as cleaning the ducts. The work covers filter sections, dampers and louvres and drain trays, and the jobs we see most are units that have only ever had filter changes and dust built up on fan impellers.
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.
It’s worth checking any contractor’s accreditations. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

How the job changes from site to site
Filters
Filters are the first line of defence in the unit. We check them, and clean or change them as agreed in the quote, and the housing around them is cleaned too.
Fans and fan sections
Dust on a fan impeller adds weight and wear. Cleaning keeps it running as intended.
How it 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 are in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes one overnight shift for many single units, with bigger plant phased. If you can send photos, we can arrive in Troy Town knowing what to expect.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- 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 site rules, permits or sign-in
- Let us know how we reach the system, including roofs, risers and plant rooms

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. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Troy Town: your questions answered
Do you clean school ventilation in Troy Town 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 Troy Town. Send us your term dates when you call 0345 646 2711 or send us an email, and we will fit the work in.
Will you come out to Troy Town?
Yes, Troy Town is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
Which sectors do you work in?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.
How do you keep the site clean during the work?
By covering it before any work starts. The work is kept contained and clean down when we finish.
Can one contract cover all our sites?
Yes. One number covers all your sites in our area, with visits on a regular schedule.
What is TR19?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not law, but it’s the benchmark.
What information do you need?
Just the basics: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. After that, simply phone us on 0345 646 2711 or send us an email.
Does the AHU have to be shut down for cleaning?
Yes. The fan must be stopped and the unit isolated, so we plan it for a time that suits the building.
When something else is needed
Some problems need a different service or another trade:
- Leaking heating or cooling coils
- Ductwork downstream of the unit, which is a separate clean
- Faulty motors, drives or bearings
If in doubt, call 0345 646 2711 or send us an email and we will say what we think.
Parts of the system we cover
- Dampers and louvres
- Internal panels
- Filter sections
- Heating and cooling coils
- Drain trays
- Supply and extract fans
For landlords and multi-site operators
We also work for facilities teams across offices, schools and healthcare in Troy Town and across Kent. Work can be phased by floor, building or site to keep disruption down.
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.
What happens if it’s left?
A light clean now is simpler than a heavy one later. Years of build-up make the job longer and harder, especially where there’s been moisture. Our emergency line runs 24/7, but a planned visit to Troy Town is calmer for everyone.
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered, and you’ll get one fixed quote.
