AHU cleaning for kitchens and businesses in Perivale
Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. We clean coils with methods suited to their condition, taking care not to damage the fins. Common call-outs are for units needing a clean before a new tenant or handover and plant that has been serviced but not cleaned, on supply and extract fans, internal panels and filter sections.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. For a building in Perivale, dust settles in the units and ducts year after year, which is what TR19® Air cleaning deals with.
A written report with pictures follows every visit, 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.

Multi-site and managed buildings
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.
What happens on the day
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. All told, the work takes from a few hours for a compact unit to a day or more for a large one. Managed blocks in London often need contractors booked in ahead, and we’re happy to deal with the agent directly for a site in Perivale.
- The survey covers the unit, its access and how it can be shut down.
- 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.
- We close every panel, hand the unit back and send the report and certificate.
Getting ready for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Find the previous report, if there is one
- Make sure someone can let us in and lock up afterwards
How to get a quote
Getting a quote does not take long. Call or email with a few details and you’ll usually have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.

Why act early in Perivale
Leave an AHU uncleaned and the dirt doesn’t stay put. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. London buildings are shared, so a fire or failure in one system can reach the neighbours above and beside you.
We don’t list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we will explain what it covers.
Why book with us
- Fully insured
- CHAS and SafeContractor accredited, with ISO 9001
- One contact for all your sites in London and the South East
- A fixed price before any work starts

Between visits
After the visit, a few habits help the work last:
- Do not store bins or materials near the intake
- Look at the condensate drain whenever the unit is serviced
- Keep the certificate and photo report with the plant records
- Keep inspection doors on the unit in good order
You receive a TR19® certificate and a photo report after the clean. Keep both with the building’s maintenance records.
Do not let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
Different parts, different methods
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. A clean fan runs more smoothly.
Internal casing and panels
We open each section through its doors and close them securely when we are done before the unit is handed back.
When it’s something else
Not every problem is solved by AHU cleaning, and we’d rather say so up front. It does not solve:
- Breakdowns that need a mechanical engineer
- Leaking heating or cooling coils
- Ventilation that was badly designed in the first place
Not sure which it is? You can ring 0345 646 2711 or email us and we will tell you honestly before booking.

When to call us in Perivale
Planned maintenance often covers belts, motors and filters but not cleaning. That means a unit can tick every service box and still be carrying years of dirt.
Any of these means the system needs a check-up:
- Filters that are clogged or overdue
- Coils clogged with dust and debris
- Blocked condensate drains and slimy trays
- Air handling units never cleaned inside
If you manage shops or offices close to South Greenford station, a TR19® Air inspection shows whether the ductwork needs cleaning.
Before booking anyone

FAQs for Perivale
Can ventilation in schools around Perivale be cleaned out of term?
Yes. Half-terms and the summer break are the natural time for school work. With about 35 schools and colleges on the FSA’s register within roughly a mile and a half of Perivale, it pays to plan holiday dates ahead. You can ring 0345 646 2711 or use the quote form with the dates the site is empty.
Can the work in Perivale be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. That way a site in Perivale does not have to lose a day’s trading. Your opening times are the first thing we ask for.
Do you repair air handling units?
The clean includes noting faults, but repairs sit with your maintenance contractor, with the details in the report.
Can you come out in an emergency?
Yes, day and night, every day of the year. Our office is open from 8am to 6pm on weekdays, and the emergency line covers the rest.
Can one contract cover all our sites?
Yes. One number covers all your sites across London and the South East, with visits on a regular schedule.
Which sectors do you work in?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
What’s included in an AHU clean?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. What happens to the filters is agreed when we quote.
How long does an AHU clean take?
It takes anything from half a day for one small unit to several shifts for a plant room full of them. The unit’s size and condition make the biggest difference, and we’ll confirm the time when we quote.
