How we handle AHU cleaning in Henley-on-Thames
Every supply and extract system relies on the air handling unit at its centre: 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, which is why we clean the unit itself, not just the ducts. Common call-outs are for blocked condensate drains and slimy trays and odours coming through the supply air, on internal panels, supply and extract fans and drain trays.
Visits to a place like Henley-on-Thames are fitted around opening hours. The method does not change: inspect first, clean, then record what was done.
Think of the report as the system’s health record: a dated account with photos of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Between visits
How long the results last depends on use and care. We suggest:
- Diary the inspection date recommended in the report
- Make sure the unit’s access doors open easily
- Watch for drips or damp patches near the plant
- Report musty smells from the vents straight away
The report suggests a date for the next inspection or clean, based on what we found. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
When something else is needed
A few issues sit outside what this work can do:
- Mechanical faults with motors, belts or bearings
- Controls and BMS settings that run the unit
- Leaking heating or cooling coils
If in doubt, ring 0345 646 2711, or email photos and we’ll say what we think before booking.

Henley-on-Thames: your questions answered
Can a school’s ventilation in Henley-on-Thames be done out of term time?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 7 schools and colleges with food registrations within roughly a mile and a half of Henley-on-Thames. You can phone us on 0345 646 2711 or email us with the dates the site is empty.
Can you get to a site in Henley-on-Thames?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
Can you clean without disrupting the building?
Yes, if daytime working isn’t practical. Tell us when the unit can go off and we will work to that.
How far ahead should we book?
That depends on the slot you want and the size of the job. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.
How much does AHU cleaning cost?
It depends on the site, so we quote each one individually. For a quote, phone us on 0345 646 2711, or email photos with the site type, opening hours and a few photos.
Do you look at the system first?
Yes, always. Diagnosis comes before treatment: the survey shows what needs doing and what access we need, and the quote is based on that.
What do you do to protect the area?
With sheeting and covers, before anything else happens. We keep the work contained and leave the area clean.
What happens if you cannot reach some of it?
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.
How we price AHU cleaning
Your quote is based on your site. We take into account:
- What state the system is in
- The times the site is available
- How big the system is
- Site requirements such as sign-in and permits
The cost depends on the size of the system, what state it’s in and access to every part of it. You get a fixed price before we start, so you know where you stand.
Asking for a quote
A few details help us quote accurately. With your enquiry, please include:
- Where the site is and what kind of site it is
- How we’d reach plant on a roof or in a plant room
- Your opening hours and when the area is out of use
- Any symptoms, from odd noises to smells or leaks
We do not publish a price list, because every site is different. We look at your system first, from photos or on a visit, then send a fixed quote. To start, call 0345 646 2711, or send details by email.

Different parts, different methods
Drain trays
Older trays can corrode and start leaking. We record their condition with photos so repairs can be planned.
Internal casing and panels
Access doors and panels are opened in turn and closed properly afterwards before the unit is handed back.
For landlords and multi-site operators
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so records stay tidy.
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
The process
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. For a site near Henley-on-Thames, the work is booked around your opening hours, evenings and weekends included.
- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- After photos are taken and the certificate issued.
How to prepare
- Have your last certificate or report to hand
- Plan for cooking equipment or plant to be off before we arrive
- Let us know about permits to work or site inductions
