How we handle AHU cleaning in South Kensington
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 pictures, so you can see the unit’s condition for yourself. The work covers supply and extract fans, drain trays and internal panels, and the jobs we see most are dirty fans and fan housings and units that have only ever had filter changes.
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. In a building in South Kensington, dust and debris build up in the units and ductwork over time, which is what TR19® Air cleaning deals with.
Every visit ends with a written report and photos, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Your questions about AHU cleaning in South Kensington
Can the work in South Kensington be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Let us know the hours you’re closed and we will book within them.
Can a school’s ventilation in South Kensington be done out of term time?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 61 schools, colleges and universities with registered kitchens within about a mile and a half of South Kensington. Tell us your holiday dates and we will book the visit for when the site is empty.
Are you accredited?
We hold 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.
Do you cover South Kensington?
Yes. Our area takes in London and the counties of South East England, and that includes South Kensington.
Is there a report after cleaning?
Yes. You receive a certificate and a report showing each section before and after, with any faults we noticed.
What types of premises do you cover?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
Are you insured?
Yes. We are fully insured, and the details are available on request.
Can you price the work without visiting?
Yes, if we can see what we need. If not, a site survey comes first, then a fixed quote.
Part by part
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. We plan safe access as part of the survey so the quote reflects it.
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. Cleaning keeps it running as intended.
What happens if it’s left?
Cleaning a unit while it only has light dust is quick. Leave it for years and dirt bakes onto coils and casings, especially where there’s been moisture. A booked night’s work in South Kensington costs you no trading time; an unplanned closure does.
Working hours, access and the scale of the site all affect the cost. We take each of them into account, and the price is fixed before we start.

When to call us in South Kensington
An overdue filter loads up with dirt, cutting airflow and sometimes letting dirty air bypass them altogether. Then the rest of the unit takes the load.
Look out for these warning signs:
- Dust-coated heating and cooling coils
- Drain trays holding standing water
- Stale or musty smells from the ventilation
- Leaves and litter drawn into the unit
Wherever a school like Our Lady of Victories RC Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
What your quote should include
- Whether the quote shows VAT
- If they look at the system before pricing
- What insurance they carry
- How they set the interval to the next visit
Aftercare tips
So the system stays in good health:
- Make sure the unit’s access doors open easily
- Report musty smells from the vents straight away
- Keep filter changes on time and recorded
- Keep the certificate and photo report with the plant records
Photos in the report cover the filters, coils, drain tray, fan and casing, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Change or clean filters on time. Once filters clog, dirt starts getting past them.

How we price AHU cleaning
Sites vary more than people expect. The main factors:
- How big the system is
- Whether several sites go on one quote
- The condition we find in the survey
- Site rules, permits and inductions
You will not find a price list here, because each job is priced on what it involves. For a fixed quote, call 0345 646 2711, or email photos, and we will explain what it covers.
What to send for a quote
To help us quote quickly, send us:
- The paperwork from the last visit, if you have it
- The roof, plant room or outside wall the system runs to
- Where the site is and what kind of site it is
- When the site is open and when it’s quiet
Getting a quote doesn’t take long. Call or email with a few details and you’ll normally have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
In-house cleaning or a specialist?
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
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.
Ventilation in South Kensington buildings
The FSA’s food hygiene register lists about 61 schools, colleges and universities, about 41 caring premises (care homes, nurseries and hospitals) and about 144 hotels, B&Bs and guest houses with registered kitchens or food service in South Kensington and the streets around it, up to about 1.5 miles out. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. Royal Marsden Hospital is the nearest hospital, about less than half a mile east of South Kensington. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes. Many London buildings have had their ductwork altered through several fit-outs, so an inspection comes first.
Healthcare ventilation, from large hospitals like Royal Marsden Hospital (about within half a mile east) to small clinics, depends on clean filters, coils and ducts. If you run an office near West Brompton station, its supply ductwork can gather dust for years before anyone looks inside.

The process
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool first, and floors and nearby surfaces are sheeted. The work itself takes anything from half a day for one small unit to several shifts for a plant room full of them. A name and number for whoever controls access to the building in South Kensington saves time on the night.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Let us know when the site is closed or quiet
- Mention any sign-in, permit or induction we need
