How we handle AHU cleaning in Shirley Oaks
Units vary a lot in size, age and layout, whether it’s a compact unit in a ceiling void or a big unit on the roof. We look at the unit first, from pictures or a site visit, and give you a fixed quote, so you know where you stand. The work covers drain trays, dampers and louvres and heating and cooling coils, and the jobs we see most are air handling units with blocked filters and odours coming through the supply air.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so ventilation cleaning in Shirley Oaks is typically planned out of hours. Parking and loading are agreed with the building in advance.
The report is your 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.

Multi-site and managed buildings
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.
Whether it’s one building or many, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with pictures.

What else we do in Shirley Oaks
Staff cleaning versus specialist work
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
Leave it or put it right?
Dirty coils and fans make the unit strain to move the same air. The result is extra wear and a building that doesn’t feel as comfortable, and a clean on your terms beats a breakdown on nobody’s. London sites work long hours, and the longer a job is left, the bigger it gets.
What you pay reflects the actual work. That is why we survey first, from pictures or on site, and the price is agreed before we start.
Why book with us
- Fixed quotes from a survey or pictures
- A written report with pictures after every visit
- In business since 2009
- CHAS and SafeContractor accredited, with ISO 9001
What happens on the day
We start by comparing what we find with the survey or your pictures. Anything unexpected is raised with you before we go further. After that, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Shirley Oaks.
- We start with a survey of the unit and a fixed quote for the work.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Drain trays are cleared and cleaned and the outlet checked.
- We close up the unit and send the certificate and before and after photos.
Preparing for the visit
- Make sure equipment near the work can be switched off and left to cool
- Name a contact who can let us in at the agreed time
- Clear loose items from the work area
Get a fixed quote
Here’s what helps us quote: where the site is, what it is and its opening hours, a few photos and the last certificate or report, if there is one. Once you have those, ring 0345 646 2711, or send details by email.

What AHU cleaning looks like in Shirley Oaks
There are about 17 schools, colleges and universities, about 70 hospitals, care homes and childcare premises and about 6 hotels and guest houses on the FSA’s food hygiene register in Shirley Oaks and the streets around it, up to about 1.5 miles out. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. For Shirley Oaks, the closest hospital is National Psychosis Unit, roughly 1.1 miles east. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital. Many London buildings have had their ductwork altered through several fit-outs, so an inspection comes first.
For schools like Oasis Academy Shirley Park, the holidays are the usual time to inspect and clean ventilation.

Do you need AHU cleaning in Shirley Oaks?
An overdue filter loads up with dirt, 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.
Signs it’s time to call us include:
- Debris and leaves in the fresh air intake
- Dirty fans and fan housings
- Air handling units never cleaned inside
- Odours coming through the supply air
Hospitals such as National Psychosis Unit (about 1.1 miles east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Shirley Oaks are no different.

Keeping the system healthy
To keep the system working properly between visits:
- Watch for drips or damp patches near the plant
- Flag stale or damp smells in the supply air
- Keep the area around the fresh air intake clear
- Make sure condensate is draining away
We recommend when the unit should next be inspected or cleaned, taking into account how dirty it was. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
Shirley Oaks: your questions answered
Can you clean school ventilation in Shirley Oaks during the holidays?
Yes, out-of-term visits are normal for schools. The FSA’s register shows about 17 schools and colleges with food registrations within roughly a mile and a half of Shirley Oaks. Just call 0345 646 2711 or drop us a line with your term dates and we’ll plan around them.
Do you work at weekends in Shirley Oaks?
Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Shirley Oaks needn’t be disturbed. Your opening times are the first thing we ask for.
Can you come out in an emergency?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we’ll advise on what to do next.
How often should an air handling unit be cleaned?
That’s set by inspection, in line with TR19® Air. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
Are you fully insured?
Yes, we are fully insured. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
Which parts of an air handling unit do you clean?
Every section that collects dirt: filters, coils, tray, fan and panels. The survey confirms what’s in your unit before we quote.
Will we get paperwork for the AHU clean?
Yes, both a certificate and a report with pictures. It includes a recommended date for the next check.
Can you quote from photos?
Yes, for many jobs. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote typically follows within one working day. Some sites still need a visit, and we will say so.
What AHU cleaning can’t fix
In fairness, some problems need a different fix:
- Faulty motors, drives or bearings
- Building management system faults
- Airflow problems caused by the system’s design
Not sure which it is? You can give us a ring on 0345 646 2711, or send details by email and we’ll tell you honestly.
