About our AHU cleaning in Great Oakley
Think of an AHU clean as a full check-up for the ventilation. We look inside each section, clean what we find and record it with photos, so you can see the unit’s condition for yourself. Common call-outs are for dirty fans and fan housings and rooms that smell stuffy when the system runs, on heating and cooling coils, dampers and louvres and supply and extract fans.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
For insurers and inspectors, the record counts. So every job comes with a written report and photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

When to call us in Great Oakley
Filters catch most of the dust, but not all of it. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
Signs it’s time to call us include:
- Debris and leaves in the fresh air intake
- Plant that needs cleaning after a refit
- Units that have only ever had filter changes
- Dust-coated heating and cooling coils
An inspection comes first for any ventilation job around Great Oakley, so the cleaning matches what’s there.

Questions from Great Oakley
Do you clean school ventilation in Great Oakley in the holidays?
Yes. Half-terms and the summer break are the natural time for school work. There are about 2 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Great Oakley. Send us your term dates when you phone us on 0345 646 2711 or drop us a line, and we will fit the work in.
Is Great Oakley within the area you cover?
Yes, Great Oakley is part of our area, however small the site. Just mention lanes, gates or anything else about the site when you book.
When should our AHU next be cleaned?
That is set by inspection, in line with TR19® Air. Units in heavy use or in sensitive buildings may need attention more often.
Will you repair the fan or motor?
Our AHU work is cleaning rather than mechanical repair. If we spot a fault, we note it in the report so your maintenance contractor can deal with it.
Do you work with multi-site operators?
Yes. Tell us the addresses and what each needs and you’ll get one fixed quote.
Does the AHU have to be shut down for cleaning?
Yes. The unit has to be shut down and isolated before it’s opened. The shutdown is planned with whoever runs the building.
Which accreditations do you hold?
Our accreditations are CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
What do you clean inside the unit?
All the internal parts the air touches, from intake to discharge, including coils, fan and drain trays. The photo report shows each section before and after.

Why deal with it now?
Facilities teams are often asked for evidence that the ventilation is looked after. A TR19® certificate and photo report give you that, for audits, tenants or your own peace of mind. Equipment tucked in a roof space or outbuilding near Great Oakley rarely gets looked at unless someone books it.
The cost depends on the size of the system, what state it’s in and how easy it is to reach. You get a fixed price before any work starts, so you know where you stand.

- CHAS and SafeContractor accredited, with ISO 9001
- One contact for all your sites in London and the South East

How the job changes from site to site
Internal casing and panels
We open each section through its doors and close them securely when we’re done before the unit is handed back.
Drain trays
Drain trays can rust and leak over time. We record their condition with pictures so you can decide on any repairs.

Fixed quotes for AHU cleaning in Great Oakley
Every site gets its own quote. This is what makes a difference:
- Parking and loading at the site
- The condition we find in the survey
- How big the system is
- Any permits to work or inductions
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you are unsure, call 0345 646 2711 or email us and we’ll give you an honest view and a fixed quote.
What we need to know
To speed up the quote, please include:
- How we’d reach plant on a roof or in a plant room
- Problems your staff have spotted
- Close-ups of filters, grilles, hatches or access panels
- Your last certificate, test record or report
The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.
What your team can do, and what needs us
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
How it works
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes half a day to a full day per unit, with large plant planned over several shifts. For a village or hamlet like Great Oakley, tell us about narrow lanes, gates and parking when you book.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
Preparing for the visit
- Clear the space around the work
- Mention any sign-in, permit or induction we need
- Agree a time when the area can be out of use

Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
