Common reasons sites call us include:
- Plant that has been serviced but not cleaned
- Filters that are clogged or overdue
- Stale or musty smells from the ventilation
- Dirty coils holding back the airflow
For workplaces around Vauxhall station with mechanical ventilation, cleaning can be done in the evening or at weekends.

About our AHU cleaning in Kennington
Our AHU cleans for sites in Kennington cover the parts that collect dirt: the filter section, heating and cooling coils, drain trays, fan and casing. You get a TR19® certificate and a photo report showing the unit before and after. Common call-outs are for intake sections clogged with outdoor debris and plant that needs cleaning after a refit, across drain trays, heating and cooling coils and supply and extract fans.
Across London, offices, hotels, schools and healthcare buildings rely on mechanical ventilation, much of it supplied through air handling units on roofs or in basements. For a building in Kennington, dust settles in the units and ducts year after year, which is what TR19® Air cleaning deals with.
We have been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

Managing agents and facilities teams in Kennington
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.
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
Honest limits
AHU cleaning can’t fix everything, and we’ll tell you before we start. It doesn’t solve:
- A system that’s undersized for the building
- Building management system faults
- Damaged coils beyond cleaning
Not sure which it is? You can phone us on 0345 646 2711, or send details by email and we’ll tell you honestly before booking.
Parts of the system we cover
- Filter sections

Leave it or put it right?
Tenants, auditors and owners may want proof that the air handling plant is kept clean. Our certificate and photo report give you clear evidence, for audits, tenants or your own peace of mind. For a site in Kennington, fitting the work in overnight now is far easier than closing at short notice later.
The cost depends on how big the system is, the condition it’s in and access to every part of it. You get a fixed price before we start, so there are no surprises.

Ventilation in Kennington buildings
Food Standards Agency records list about 109 schools, colleges and universities, about 54 caring premises (care homes, nurseries and hospitals) and about 64 hotels and guest houses registered as food businesses within roughly a mile and a half of the centre of Kennington. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. Getting kit to a London plant room usually means lifts, stairs and an agreed loading slot. Kennington’s nearest hospital, The Gordon Hospital, is about 1 mile north-west. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Hospitals such as The Gordon Hospital (about 1 mile north-west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Kennington are no different. Classrooms and halls at schools such as St Stephen's Church of England Primary School are easiest to work in when pupils are away.
Kennington is about 2 miles south-west of London, in Greater London. Kennington gets the same approach as every site we work on: diagnosis first, a fixed price, out-of-hours working where needed and a written report with pictures. Kennington is one of 764 places in Greater London we cover for commercial clients.

How the job changes from site to site
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. We note any we find in the report.
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. A clean fan runs more smoothly.
Kennington questions
Do you do school ventilation cleaning in Kennington in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 109 schools and colleges with food registrations within roughly a mile and a half of Kennington. Tell us your holiday dates and we will book the visit for when the site is empty.
Is parking a problem for work in Kennington?
Tell us where a van can stop near your site in Kennington, and about any building rules on loading. Where restrictions apply in the day, an evening or overnight visit usually gets round them.
What does TR19 mean?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
How much notice do you need?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.
What if parts of the system cannot be reached?
The report shows them clearly. In ductwork, new access panels are often the answer, and we can fit those.
What information do you need?
A short description and a few photos plus the address and your hours. We’ll ask for anything else we need.
Is there a report after cleaning?
Yes, a TR19® certificate and a photo report. It includes a recommended date for the next check.
Do you offer maintenance contracts?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. Each report recommends when the next visit should be.
Staff cleaning versus specialist work
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
What happens on the day
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. The visit itself takes a single shift for a typical unit, longer for large or heavily soiled ones. Loading bays, visitor permits and roof access are the first things we ask about for a site in Kennington.
- We start with a survey of the unit and a fixed quote for the work.
- With your site team, the unit is switched off and isolated, then the area around it 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
- Mention any parking or loading restrictions
- Tell us the best time to work, such as after service or at a weekend
- Allow time for equipment near the work to be turned off and cool down
Getting a quote
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
