What we’re called out for in Gubbion's Green
Filters catch most of the dust, but not all of it. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
Common reasons sites call us are:
- Units that have only ever had filter changes
- Dust built up on fan impellers
- Plant that needs cleaning after a refit
- Intake sections clogged with outdoor debris
If you manage a school such as Great Leighs Primary School, ventilation cleaning is best booked for the holidays.
Before booking anyone
- Whether they recommend a next date
- What’s included in the scope, part by part
- Proof of insurance
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
How we handle AHU cleaning in Gubbion's Green
No two plant rooms are the same, whether it’s a compact unit in a ceiling void or a big unit on the roof. Every job starts with a survey, from pictures or on site, followed by a fixed quote, so you know where you stand. The work covers filter sections, heating and cooling coils and internal panels, and common reasons people get in touch are intake sections clogged with outdoor debris and units that have only ever had filter changes.
In a village or hamlet like Gubbion's Green, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
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.

What affects the cost of AHU cleaning
Some jobs are bigger than they look, and some smaller. The main factors:
- The condition of the system
- Whether it’s a one-off visit or part of a schedule
- Working hours and out-of-hours timing
- Whether we need access equipment or extra panels
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll go through it with you.
What to send for a quote
Before you ask for a quote, gather:
- Photos showing the whole system and its surroundings
- Your opening hours and when the area is out of use
- Detail shots of panels, filters and grilles
- Any previous report or certificate

Your questions about AHU cleaning in Gubbion's Green
Can you do AHU cleaning in Gubbion's Green?
Yes, Gubbion's Green is within the area we cover across London and the South East. Just call us on 0345 646 2711 or send us an email with a few details of the site.
Do you work in villages like Gubbion's Green?
Yes, we work in villages as well as towns, and Gubbion's Green is covered. Let us know about access, parking and anything unusual about getting there when you book.
Is there a report after cleaning?
Yes. Every clean comes with a TR19® certificate and a photo report. Keep them in the maintenance log.
What does TR19 mean?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t legislation, but it’s the standard people check against.
Do you offer maintenance contracts?
Yes, of course. Tell us what you have and how it’s used and we’ll propose a schedule with a fixed quote.
Will you repair the fan or motor?
Our AHU work is cleaning rather than mechanical repair. Any faults we notice are recorded for your maintenance team to follow up.
Does the AHU have to be shut down for cleaning?
Yes. Cleaning needs the unit off and isolated, and we time the work to suit the site.
Where does the waste go?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. We don’t leave it behind.
In-house cleaning or a specialist?
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
When something else is needed
Not every problem is solved by AHU cleaning, and we will tell you before any work starts. It doesn’t solve:
- Coils that are corroded or leaking and need replacing
- Ductwork downstream of the unit, which is a separate clean
- Airflow problems caused by the system’s design
If in doubt, call 0345 646 2711 or use the quote form and we will say what we think.
Parts of the system we cover
- Filter sections
- Supply and extract fans
- Internal panels
- Heating and cooling coils

The process
Night work is normal for us. 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 one overnight shift for many single units, with bigger plant phased. If you can send photos, we can arrive in Gubbion's Green knowing what to expect.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- After pictures are taken and the certificate issued.
How to prepare
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Make sure someone can let us in and lock up afterwards
- Clear loose items from the work area
How to get a quote
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before any work starts.

Keeping the system healthy
Results last longer with the right care. We suggest:
- Plan the next inspection before the last report gets filed away
- Change filters on schedule and log each change
- Keep inspection doors on the unit in good order
- Report musty smells from the vents straight away
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can quote for both.
Check drain trays and condensate drains during routine maintenance. A drain that’s cleared early never gets to the slime stage.
Different parts, different methods
Drain trays
Older trays can corrode and start leaking. Their condition goes into the report with pictures so you can decide on any repairs.
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.
