AHU cleaning for kitchens and businesses in Hanwell
We clean air handling units for buildings in Hanwell and across Greater London, working to TR19® Air, in offices, schools, hospitals, care homes and retail. The work is timed around when the system can be switched off, including evenings, nights and weekends. Typical jobs include dirty coils holding back the airflow and fan sections that haven’t been cleaned in years, across dampers and louvres, supply and extract fans and internal panels.
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. For a building in Hanwell, dust settles in the units and ducts year after year.
Each visit ends with a written report and pictures, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

How the visit works
Protection comes first: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. The work on site takes from a few hours for a compact unit to a day or more for a large one, and the area is cleaned down before we leave. Loading bays, visitor permits and roof access are the first things we ask about for a site in Hanwell.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before photos of each section of the unit.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- After pictures are taken and the certificate issued.
Before we arrive
- Clear the space around the work
- Mention any sign-in, permit or induction we need
- Find the previous report, if there is one

Common questions in Hanwell
Can you come to Hanwell after we close?
Yes, we can come after you close and finish before you open. It means the site in Hanwell keeps running as normal. Tell us your opening hours when you ask for a quote.
Do you do school ventilation cleaning in Hanwell in the summer 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 Hanwell. Send us your term dates when you call us on 0345 646 2711, or send details by email, and we will fit the work in.
Is there a survey before the work?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it, and the quote is based on that.
Do you work in Hanwell?
Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, and that includes Hanwell.
What do you clean inside the unit?
Every section that collects dirt: filters, coils, tray, fan and panels. The survey confirms what’s in your unit before we quote.
Where does the waste go?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on, so it does not spread.
What is TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
Do you work with multi-site operators?
Yes. Send the list of sites and the work at each and you will get one fixed quote.

In-house cleaning or a specialist?
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
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. Leave those to us.
What affects the cost of AHU cleaning
We quote each job individually. This is what makes a difference:
- The number of sites or systems
- How easy every part is to reach
- Working hours and out-of-hours timing
- One-off work versus a regular cycle
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. You will have a fixed price before any work starts.
Helping us quote
Photos and a few facts are often enough to price the work. Send what you can of the following:
- Any access panels or hatches you can see
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- A few general shots of the system
- The postcode and the type of business
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. If we need to see the system first, we book a survey around your hours.
What the work involves, part by part
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. The space underneath is protected with sheeting first.
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. A clean gets air moving through the coil properly again.
Signs you need AHU cleaning in Hanwell
Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For the people using the building every day, that is the air they breathe for hours on end.
It’s time to book a visit if you see:
- Rooms that smell stuffy when the system runs
- Condensate trays that won’t empty
- Dirty fans and fan housings
- Dirty coils holding back the airflow
Wherever a school like St Joseph's Catholic Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
What your quote should include
- Exactly which parts of the system are covered
- Whether the work can be done while the site is closed
- How areas they can’t reach will be recorded
- If they look at the system before pricing
What AHU cleaning cannot fix
We’d rather tell you now than book work that won’t help, so here are the limits:
- Coils that are corroded or leaking and need replacing
- A system that’s undersized for the building
- The supply and extract ducts, quoted separately
Not sure which it is? You can phone us on 0345 646 2711, or send details by email and we will tell you honestly.

What AHU cleaning looks like in Hanwell
Going by the FSA’s register, there are about 46 schools, colleges and universities, about 105 care, childcare and hospital premises and about 4 hotels, B&Bs and guest houses serving food in and around Hanwell, up to about a mile and a half out. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Getting kit to a London plant room normally means lifts, stairs and an agreed loading slot. Hanwell’s nearest hospital, Ealing Hospital, is about under half a mile west. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Hospitals such as Ealing Hospital (about under half a mile west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Hanwell are no different. For workplaces around Hanwell station with mechanical ventilation, cleaning can be done in the evening or at weekends.
Hanwell is about 1 mile west of Ealing, in Greater London. Sites in Hanwell get the same service as everywhere we cover: diagnosis first, a fixed price, out-of-hours working where necessary and a written report with photos.

Landmarks near Hanwell
We work in commercial kitchens and buildings around Drayton Manor High School, Cuckoo Schools and Drayton Green, among other places. There’s a railway station in Hanwell itself: Hanwell station. Well-known places in the area include Ealing Hospital (less than half a mile west) and Gunnersbury Park House - Large Mansion (2.3 miles east). Open spaces near Hanwell include Middle Lake and Castlebar Hill.
Why deal with it now?
A clogged coil or dirty fan makes the unit work harder for the same airflow. That means more wear on the motor and rooms that feel less fresh, and a planned clean is far less disruptive than a breakdown. In Hanwell, as across London, ductwork often passes through shared risers and other people’s space.
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.
