AHU cleaning for kitchens and businesses in Pinner Green
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. If you’re dealing with air handling units with blocked filters and dust built up on fan impellers, we can put it right, from supply and extract fans, heating and cooling coils and internal panels onwards.
London offices and flats often have ductwork added through successive refits, leaving sections that are hard to reach and seldom cleaned. In Pinner Green, as elsewhere, cleaning starts with an inspection of what’s there.
For insurers and inspectors, the record counts. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

How the visit works
When we arrive, we check the system against the survey or the photos you sent. If anything is different, we talk it through with the person on site before carrying on. From there, it takes one overnight shift for many single units, with bigger plant phased. If your building in Pinner Green has sign-in rules, permits or key holders, mention them when you book.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.

Advice
What the work involves, part by part
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe with your site team.
Drain trays
The drain tray collects water from the cooling coil. Standing water and slime are removed and the outlet is checked.
Ventilation in Pinner Green buildings
The FSA’s food hygiene register lists about 22 schools, colleges and universities and about 39 hospitals, care homes and childcare premises with registered kitchens or food service within 1.5 miles or so of the middle of Pinner Green. Busy, occupied buildings like these are where clean supply air matters most. Many London buildings have had their ductwork altered through several fit-outs, so an inspection comes first. About 0.9 miles north-west of Pinner Green is Northwood and Pinner Cottage Hospital, the nearest hospital. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
Wherever a school like Harlyn Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

For landlords and multi-site operators
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements, and we’ll send a fixed quote.
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
In-house cleaning or a specialist?
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
When to call us in Pinner Green
Most units live out of sight on roofs, in plant rooms or in ceiling voids, so they’re easy to forget about. It’s easy for a long time to go by without anyone opening the panels.
Common reasons sites call us include:
- Air handling units due a clean after building work
- Units that have only ever had filter changes
- Intake sections clogged with outdoor debris
- Coils clogged with dust and debris
Healthcare buildings such as Northwood and Pinner Cottage Hospital, about 0.9 miles north-west, depend on their ventilation; if you manage a surgery, clinic or care home near Pinner Green, yours matters too.

Pinner Green questions
Do you work overnight in Pinner Green?
Yes. We work evenings, overnight and at weekends. That way a site in Pinner Green does not have to lose a day’s trading. Let us know the hours you’re closed and we will book within them.
Do you clean school ventilation in Pinner Green in the holidays?
Yes. The holidays are the usual time for school work. There are about 22 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Pinner Green. Booking early in the term gives the best choice of holiday dates.
Can you price the work without visiting?
Yes, where the pictures show enough. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
Do you do ventilation duct cleaning too?
Yes. We clean supply and extract ductwork to TR19® Air as well. Cleaning the unit and ducts together often makes sense, and we can quote for both.
What does AHU cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote and we’ll normally reply within one working day.
Do you work with multi-site operators?
Yes. We work across South East England and London, so we can schedule a run of sites as one programme. Every site has its own report.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Do you have insurance?
Yes, fully. We also hold CHAS and SafeContractor, for sites that check contractor safety.
