How we handle AHU cleaning in Ashampstead Green
Where a building in Ashampstead Green has had little more than filter changes, there may be dirt on the coils, fan and casing that nobody has looked at. A full clean deals with all of it. Common call-outs are for debris and leaves in the fresh air intake and odours coming through the supply air, on drain trays, internal panels and filter sections.
Work in a small place like Ashampstead Green starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
We’ve been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

Ashampstead Green questions
Is Ashampstead Green in your area for AHU cleaning?
Yes. Our area runs across London and the South East, Ashampstead Green included. Just phone us on 0345 646 2711, or email photos with a few details of the site.

Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Ashampstead Green needn’t be disturbed. Tell us your opening hours when you ask for a quote.
What does TR19 mean?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t legislation, but it’s the standard people check against.
Do you work with multi-site operators?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together on one programme. Each site gets its own report and pictures.
Can you price the work without visiting?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, then a fixed quote.
What do you clean inside the unit?
Everything inside the unit that air passes over, from the intake and filters through the coils and fan to the outlet. You get a photo report showing each part before and after.
Is there a report after cleaning?
Yes. Every clean comes with a TR19® certificate and a photo report. Keep them in the maintenance log.
How much does AHU cleaning cost in Ashampstead Green?
Every site is different, so each gets its own fixed quote. To get one, call 0345 646 2711 or drop us a line with the site type, opening hours and a few photos.
How it works
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. The visit takes one overnight shift for many single units, with bigger plant phased. A few pictures of the system help us make the most of a visit to a place like Ashampstead Green.
- 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.
- 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 when the site is closed or quiet
- Make sure equipment near the work can be switched off and left to cool
- Mention any locked doors, roof access or ceiling voids
Get a fixed quote
Every quote begins with a look at the system, either from photos and details you send or from a site visit. Then we send a fixed price, before any work starts.

Looking after it afterwards
Looking after the system between visits is straightforward, and it helps at the next visit:
- Make sure the unit’s access doors open easily
- Watch for drips or damp patches near the plant
- Keep filter changes on time and recorded
- Plan the next inspection before the last report gets filed away
Restart the unit with your site team or maintenance contractor once we’ve finished. Keep an eye on the condensate drain over the next few days to make sure it stays clear.
Make the drain tray part of every maintenance visit. A drain that’s cleared early never gets to the slime stage.

Different parts, different methods
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. We clean the coil and the tray beneath it together.
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. The impeller, its housing and the fan chamber are cleaned.

Do you need AHU cleaning in Ashampstead Green?
Filters that are not changed or cleaned on time clog up, which cuts the airflow and can let air slip round the filter. After that, the coils and fan collect what the filter should have caught.
If you notice any of these, it’s worth a diagnosis:
- Intake sections clogged with outdoor debris
- Rooms that smell stuffy when the system runs
- Dirty fans and fan housings
- Dust-coated heating and cooling coils
An inspection comes first for any ventilation job around Ashampstead Green, so the cleaning matches what’s there.
What your quote should include
- Whether the quote shows VAT
- If the quote is a fixed price or an estimate
- What insurance they carry
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
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.
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.
For landlords and multi-site operators
When the building owner and the occupier are different, the lease normally sets out who maintains what. We’re happy to deal with either side, and the report can go to both.
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we’re happy to quote for all of it.
