AHU cleaning for kitchens and businesses in Leigh Green
All the building’s air passes through the fan, so dirt on the impeller and housing gets spread around. Fan, housing and the surrounding panels are cleaned as part of the job, once the unit has been shut down and isolated. Common call-outs are for units needing a clean before a new tenant or handover and leaves and litter drawn into the unit, on supply and extract fans, heating and cooling coils and drain trays.
Work in a small place like Leigh Green starts with agreeing access and timings.
The report is your system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

Common problems we fix in Leigh Green
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. The intake section and first filters take the brunt, and some travels further into the unit.
Most sites get in touch after spotting one of these:
- Fan sections that haven’t been cleaned in years
- Coils clogged with dust and debris
- Blocked condensate drains and slimy trays
- Plant that needs cleaning after a refit
For schools like Tenterden Church of England Junior School, the holidays are the usual time to inspect and clean ventilation.
Questions to ask before you book
- Whether a written report and pictures are included
- Whether inaccessible sections are listed on the report
- Whether the figure could change on the day
- Whether they’re fully insured
In-house cleaning or a specialist?
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Why it’s worth doing now in Leigh Green
Tenants, auditors and owners may want proof that the air handling plant is kept clean. A TR19® certificate and photo report give you that, ready to show anyone who asks. With notice, the visit to Leigh Green can be fitted around your bookings and events.
The cost depends on the size of the system, what state it’s in and access to every part of it. We give you a fixed price before work begins, so you know where you stand.

How we price AHU cleaning
The diagnosis comes before the price. We look at:
- Site requirements such as sign-in and permits
- The condition of the system
- Whether it’s a one-off visit or part of a schedule
- Whether we need access equipment or extra panels
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.
What we need to know
Photos let us diagnose from a distance. The most useful are:
- Close-ups of filters, grilles, hatches or access panels
- The roof, plant room or outside wall the system runs to
- Wide photos of the system and the area around it
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
For a fixed quote, call 0345 646 2711 or use the quote form with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. We normally come back within one working day.

The process
Each visit runs to the same pattern: sheeting and protection first, isolate whatever needs isolating, do the work, clear away and hand over the paperwork. The visit itself takes a single shift for a typical unit, longer for large or heavily soiled ones. If you can send photos, we can arrive in Leigh Green 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.
Getting ready for the visit
- Move anything stored near the system
- Let us know about permits to work or site inductions
