AHU cleaning for kitchens and businesses in East Finchley
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 dirty fans and fan housings and dirty filters cutting the airflow, across drain trays, filter sections and internal panels.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. In a building in East Finchley, dust and debris build up in the units and ductwork over time.
The report is your system’s health record: dated, with photos, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

What affects the cost of AHU cleaning
Before we fix a price, we need to know a few things. We check:
- How many systems or sites are involved
- A single visit or a regular plan
- Parking and loading at the site
- What state the system is in
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at, and you will get one fixed quote.
What we need to know
To speed up the quote, please include:
- How we’d reach plant on a roof or in a plant room
- Any symptoms, from odd noises to smells or leaks
- Photos showing the whole system and its surroundings
- When the site is open and when it’s quiet
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before any work starts.

Common questions in East Finchley
Do you work overnight in East Finchley?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in East Finchley needn’t be disturbed. When you phone us on 0345 646 2711, or email photos, mention when the site is quiet.
Can you clean school ventilation in East Finchley during the holidays?
Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 46 schools, colleges and universities with registered kitchens within about a mile and a half of East Finchley. Just call us on 0345 646 2711 or use the quote form with your term dates and we will plan around them.
What do you do to protect the area?
We cover floors and nearby surfaces with sheeting before work begins, and anything we remove is contained. At the end, the area is cleaned down.
Do you have insurance?
Yes. We carry full insurance and have been trading since 2009.
Do you repair air handling units?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We’ll flag anything we notice during the clean.
How long will the unit be out of action?
As a guide, it takes one overnight shift for many single units, with bigger plant phased. The shutdown is planned to fit, out of hours if needed.
Is a quote from photos possible?
Often, yes. With good pictures, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
Do you cover East Finchley?
Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, East Finchley included.
What we do, step by step
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 the same goes into the written report. The visit takes from a few hours for a compact unit to a day or more for a large one. Most London sites can’t stop for the day, so work in East Finchley is usually done overnight, early in the morning or at weekends.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Find the previous report, if there is one
- Plan for cooking equipment or plant to be off before we arrive
- Let us know how we reach the system, including roofs, risers and plant rooms

What we are called out for in East Finchley
Planned maintenance often covers belts, motors and filters but not cleaning. So a unit can be well maintained and still dirty.
These are the problems we see most often:
- Dirty filters cutting the airflow
- Dirty coils holding back the airflow
- Drain trays holding standing water
- Air handling units due a clean after building work
For schools like Holy Trinity CofE Primary School, the holidays are the usual time to inspect and clean ventilation.
Before you book anyone
- Whether the price is fixed
- What’s included in the scope, part by part
- What hours they’ll be on site
- How areas they cannot reach will be recorded
What happens if it’s left?
A clogged coil or dirty fan makes the unit work harder for the same airflow. The result is extra wear and a building that doesn’t feel as comfortable, and a clean on your terms beats a breakdown on nobody’s. In a London building, a problem in a duct, damper or fan rarely stays in one unit.
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote, and the price is fixed before we start.
Why us?
- Fixed quotes from a survey or photos
- Fully insured
- Every job surveyed first
- Work around your opening hours, with 24/7 emergency cover

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.
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. We clean the impeller, housing and surrounding section.
