AHU cleaning in Wexham Street
A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, in the airstream that feeds the building. Clearing and cleaning the tray is central to every AHU clean. The work covers drain trays, dampers and louvres and heating and cooling coils, and the jobs we see most are dirty fans and fan housings and dirty coils holding back the airflow.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
For insurers and inspectors, the record counts. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What we do, step by step
We are used to working while the site is closed. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. The visit itself takes a single shift for a typical unit, longer for large or heavily soiled ones. Photos of the system and how to reach it help us plan a visit to Wexham Street.
- We agree a shutdown window that suits the building.
- 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.
- After photos are taken and the certificate issued.
Getting ready for the visit
- Let us know about permits to work or site inductions
- Mention any locked doors, roof access or ceiling voids
- Tell us where we can park and unload

Advice
Common questions in Wexham Street
Do you work overnight in Wexham Street?
Yes, we can come after you close and finish before you open. The work in Wexham Street can fit around your hours. Your opening times are the first thing we ask for.
Can you clean school ventilation in Wexham Street during the holidays?
Yes, out-of-term visits are normal for schools. Around Wexham Street, the Food Standards Agency lists about 6 schools and colleges with registered kitchens within a mile and a half or so. Send us your term dates when you ring 0345 646 2711 or send us an email, and we’ll fit the work in.
Is a quote from pictures possible?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
How do you protect the area?
We start with protection: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
Where does the waste go?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on, so it doesn’t spread.
Can you fix a faulty AHU?
Our AHU work is cleaning rather than mechanical repair. Any faults we notice are recorded for your maintenance team to follow up.
How often do AHUs need cleaning?
It depends on the unit, the filters and how the building is used. Regular inspection shows when it’s due, and we’ll suggest an interval after the first clean.
What is TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not legislation, but it’s the standard people check against.
How we price AHU cleaning
A fixed price needs a few facts first. We look at:
- The size of the system
- Site rules, permits and inductions
- The times the site is available
- What state the system is in
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote and give you a fixed price before any work starts.
Helping us quote
To speed up the quote, please include:
- How we’d reach plant on a roof or in a plant room
- The paperwork from the last visit, if you have it
- The site address and the type of premises
- Any symptoms, from odd noises to smells or leaks
To help us quote: the address, the type of site and when it’s open, photos of the system and the last certificate or report, if there is one. Once you have those, give us a ring on 0345 646 2711, or email photos.
Ventilation in Wexham Street buildings
Food Standards Agency data includes about 6 schools, colleges and universities and about 11 caring premises (care homes, nurseries and hospitals) within 1.5 miles or so of the middle of Wexham Street. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. About 0.8 miles south of Wexham Street is Wexham Park Hospital, the nearest hospital. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. At about 21 miles from central London, Wexham Street sits well inside the area we cover. A survey and a fixed quote come first, then the visit at a time that suits you.
For schools like Khalsa Secondary Academy, the holidays are the usual time to inspect and clean ventilation.

For landlords and multi-site operators
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, 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.
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
When something else is needed
We’d rather tell you now than book work that won’t help, so here are the limits:
- Breakdowns that need a mechanical engineer
- The supply and extract ducts, quoted separately
- Problems with the unit’s controls or sensors
If in doubt, give us a ring on 0345 646 2711 or drop us a line and we’ll say what we think before you book.
What the work covers
- Dampers and louvres
- Supply and extract fans
- Heating and cooling coils
- Drain trays
- Internal panels
- Filter sections
What your team can do, and what needs us
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We can diagnose it and quote.
Part by part
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. The coil and its drain tray are cleaned as one job.
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. We check them, and clean or change them as agreed in the quote, and clean the filter housing.
