How we handle AHU cleaning in Barkham
An AHU clean is a thorough examination and treatment of the unit. We look inside each section, clean what we find and record it with photos, so you can see the unit’s condition for yourself. The work covers drain trays, dampers and louvres and heating and cooling coils, and people most often call us about stale or musty smells from the ventilation and leaves and litter drawn into the unit.
Somewhere as small as Barkham, ducted ventilation is usually limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
A written report with photos follows every visit, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What happens on the day
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes one overnight shift for many single units, with bigger plant phased. A quick note on how to find the site and where to park makes a visit to Barkham run smoothly.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- 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
- Make sure someone can let us in and lock up afterwards
- Find the previous report, if there is one
- Make sure equipment near the work can be switched off and left to cool

Do you need AHU cleaning in Barkham?
Most units live out of sight on roofs, in plant rooms or in ceiling voids, so they’re easy to forget about. Months can pass without anyone looking inside.
The symptoms we’re asked about most are:
- Units needing a clean before a new tenant or handover
- Stale or musty smells from the ventilation
- Leaves and litter drawn into the unit
- Dirty coils holding back the airflow
School buildings such as The Coombes Church of England Primary School are normally done in the holidays, so classrooms aren’t disturbed.
Before booking anyone
- Whether the quote is based on a survey or photos
- Whether the quote shows VAT
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- What happens if part of the system cannot be accessed
What staff can safely do
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and send you a fixed quote.
How the job changes from site to site
Filters
Filter condition tells you a lot about the rest of the unit. They’re photographed before and after for your records.
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. The intake section gets particular attention.
What affects the quote in Barkham
Before we fix a price, we need to know a few things. We look at:
- Parking and loading at the site
- The size of the system
- Whether several sites go on one quote
- Any permits to work or inductions
The cost depends on how big the system is, what state it’s in and access to every part of it. You get a fixed price before we start, so you know where you stand.
What we need to know
Photos let us diagnose from a distance. The most useful are:
- The roof, plant room or outside wall the system runs to
- Any previous report or certificate
- The postcode and the type of business
- The times we could work without disrupting the site
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.
Between visits
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Diary the inspection date recommended in the report
- Watch for drips or damp patches near the plant
- Keep inspection doors on the unit in good order
- Don’t ignore odours coming through the grilles
Restart the unit with your site team or maintenance contractor once we’ve finished. Check the drain tray is emptying over the first few days to confirm water is draining away.
Keep the area around the intake clear. What’s near the intake ends up in the unit.

Multi-site and managed buildings
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. With shared responsibility, good records help everyone.
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
Your questions about AHU cleaning in Barkham
Do you clean school ventilation in Barkham in the holidays?
Yes. The holidays are the usual time for school work. There are about 6 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Barkham. Just phone us on 0345 646 2711 or use the quote form with your term dates and we will plan around them.
Do you cover smaller places like Barkham?
Yes, Barkham is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
Will you repair the fan or motor?
AHU cleaning is what we offer here, not mechanical repairs. Any faults we notice are recorded so your maintenance contractor can deal with it.
Are you accredited?
Our accreditations are CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
What do you need from me for a quote?
The site address, the type of premises and your opening hours, plus photos of the system and your last certificate or report if you have one.
How long does it take to clean an air handling unit?
Cleaning takes half a day to a full day per unit, with large plant planned over several shifts. Large plant can be split over several shifts, so call 0345 646 2711, or email photos to talk it through.
Do you have insurance?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
How often should an air handling unit be cleaned?
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.
