About our AHU cleaning in Yiewsley
We clean the parts of the unit where dirt and moisture gather: the filter section, heating and cooling coils, drain trays, fan and casing. Every clean comes with a TR19® certificate and before and after pictures in a report. Typical jobs include fan sections that haven’t been cleaned in years and air handling units with blocked filters, on heating and cooling coils, internal panels and filter sections.
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 Yiewsley, dust and debris build up in the units and ductwork over time.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Managing agents and facilities teams in Yiewsley
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
The process
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. Most of the time goes on the work itself, which takes half a day to a full day per unit, with large plant planned over several shifts. Night and weekend working is normal for us in London, and a site in Yiewsley is no exception.
- We survey the unit from photos or on site and agree what’s included.
- We arrange the shutdown with your staff and sheet the area.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
Getting ready for the visit
- Tell us where we can park and unload
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Arrange a key holder or contact on site

FAQs for Yiewsley
Can you come to Yiewsley after we close?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Yiewsley needn’t be disturbed. Let us know the hours you are closed and we’ll book within them.
What do you need to know about parking in Yiewsley?
London parking can be tight, so details of loading bays and permits help. Where restrictions apply in the day, an evening or overnight visit normally gets round them.
Which kinds of sites do you work on?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
Which accreditations do you hold?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We are fully insured and have been trading since 2009.
Is there a report after cleaning?
Yes, a TR19® certificate and a photo report. It includes a recommended date for the next check.
Is there a survey before the work?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
Can you set up regular visits?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.
Can you fix a faulty AHU?
The clean includes noting faults, but repairs sit with your maintenance contractor, with the details in the report.
What we’re called out for in Yiewsley
Wherever there’s a cooling coil, there’s condensate. If the drain tray outlet blocks or the tray doesn’t fall properly, water stands in it, and slime and smells soon follow.
Common reasons sites call us include:
- Units that have only ever had filter changes
- Leaves and litter drawn into the unit
- Air handling units with blocked filters
- Dirty coils holding back the airflow
If you run a surgery, dental practice or care home near Yiewsley, clean ventilation matters as much to you as to a hospital like Hayes Cottage Hospital (about 1.5 miles south-west).
What your quote should include
- How VAT is shown on the quote
- What records you’ll receive afterwards
- Exactly which parts of the system are covered
- Whether a survey comes first
Why deal with it now?
Cleaning a unit while it only has light dust is quick. Years of build-up make the job longer and harder, especially where there’s been moisture. Planning ahead in Yiewsley lets you pick a quiet night rather than lose a busy one.
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 send us an email and we will give you an honest view and a fixed quote.
What you get with us
- We diagnose before we treat
- Every visit written up, with photos
- Out-of-hours work and a 24/7 emergency line
- In business since 2009
Part by part
Filters
Dirty filters cut airflow and let dirt slip past their frames. The filter section is cleaned so new or cleaned filters sit properly.
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. Anything like that is recorded with photos.
AHU cleaning around Yiewsley
Going by the FSA’s register, there are about 36 schools, colleges and universities and about 61 hospitals, care homes and childcare premises serving food within roughly a mile and a half of the centre of Yiewsley. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. London plant rooms are often on roofs or in basements reached through occupied floors. About 1.5 miles south-west of Yiewsley is Hayes Cottage Hospital, the nearest hospital. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.
If you manage a school such as Brookside Primary School, ventilation cleaning is best booked for the holidays.

Looking after it afterwards
Here’s the after-treatment advice, short and simple:
- Flag stale or damp smells in the supply air
- Clear leaves and litter away from the intake
- File each AHU report in the maintenance log
- Report water on the plant room floor
Once the clean is done, we send a TR19® certificate and a report with before and after photos. Keep both with the building’s maintenance records.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
When something else is needed
We’ll always give you a straight diagnosis, so here’s what this work can’t put right:
- Problems with the unit’s controls or sensors
- Damaged coils beyond cleaning
- Dirty ducts beyond the unit itself
Not sure which it is? You can call 0345 646 2711, or send details by email and we’ll tell you honestly before booking.
