AHU cleaning for kitchens and businesses in Bickley
All the building’s air passes through the fan, so dirt on the impeller and housing gets spread around. We clean the fan section along with the rest of the unit, with the unit switched off and made safe first. If you are dealing with dirty filters cutting the airflow and dirty fans and fan housings, we can help.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so work in Bickley is often done in the evening or at weekends. Loading and parking are planned with the building first.
We have been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

What the work involves, part by part
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. Access is planned during the survey so the quote reflects it.
Internal casing and panels
Dust settles on every internal surface of the unit. Each section is cleaned from the intake through to the outlet.
Questions from Bickley
Can you clean school ventilation in Bickley during the holidays?
Yes. Half-terms and the summer break are the natural time for school work. Food Standards Agency records list about 14 schools, colleges and universities with registered kitchens within about a mile and a half of Bickley. Tell us your holiday dates and we will book the visit for when the site is empty.
How do you handle parking and loading in Bickley?
Tell us where a van can stop near your site in Bickley, and about any building rules on loading. Much of our London work is done overnight, which helps.
Will we get paperwork for the AHU clean?
Yes, a TR19® certificate and a photo report. The report also suggests when the unit should next be inspected.
Can you look after several sites?
Yes. One number covers all your sites in our area, and visits can be set on a regular cycle.
Which sectors do you work in?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
How do you protect the area?
By covering it before any work starts. We keep the work contained and leave the area clean.
Can you quote from pictures?
Yes, for many jobs. Send a few wide pictures plus close-ups of panels, filters or grilles, and a fixed quote usually follows within one working day. Some sites still need a visit, and we’ll say so.
What’s TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t legislation, but it’s the standard people check against.
Keeping the system healthy
Here’s the after-treatment advice, short and simple:
- Clear leaves and litter away from the intake
- Make sure the unit’s access doors open easily
- Look at the condensate drain whenever the unit is serviced
- File each AHU report in the maintenance log
You receive a TR19® certificate and a photo report after the clean. They belong in the plant or maintenance log.
Make the drain tray part of every maintenance visit. A drain that’s cleared early never gets to the slime stage.
Managing agents and facilities teams in Bickley
We also work for facilities teams across offices, schools and healthcare in Bickley and across Greater London. Work can be phased by floor, building or site to keep disruption down.
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we’ll come back with a fixed quote.
How it works
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. On site, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Bickley.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- After photos are taken and the certificate issued.
Preparing for the visit
- Clear loose items from the work area
- Allow time for equipment near the work to be turned off and cool down
- Let us know about permits to work or site inductions
Getting a quote
Every quote begins with a look at the system, either from photos and details you send or from a site visit. Then we send a fixed price so you know the cost before work begins.
Advice
When it’s something else
We will not sell you work that doesn’t address the problem, so here are the limits:
- Mechanical faults with motors, belts or bearings
- Building management system faults
- Dirty ducts beyond the unit itself
If you’re not sure, just ring 0345 646 2711 or email us and we will give you a straight answer before you book.

What affects the cost of AHU cleaning
You’ll get a fixed price before work begins. It takes into account:
- The size of the system
- Where the site is and how we reach it
- What state the system is in
- Whether we need access equipment or extra panels
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll go through it with you.
Asking for a quote
You do not need the technical terms. It helps if you can send:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The site address and the type of premises
- Problems your staff have spotted
- Photos showing the whole system and its surroundings
For a fixed quote, ring 0345 646 2711, or send details by email with the site type, your trading hours and a short description of the system. A few pictures and your last certificate or report help a lot. We usually come back within one working day.
What AHU cleaning looks like in Bickley
The FSA’s food hygiene register lists about 14 schools, colleges and universities, about 38 hospitals, care homes and childcare premises and about 4 hotels and guest houses with registered kitchens or food service in Bickley and the streets around it, up to about 1.5 miles out. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. London plant rooms are often on roofs or in basements reached through occupied floors. Bickley’s nearest hospital, Bridgeways Day Hospital, is about 1 mile south. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Bridgeways Day Hospital, about 1 mile south, is the nearest hospital to Bickley, and healthcare sites of every size need their supply air kept clean. School buildings such as Bullers Wood School for Boys are typically done in the holidays, so classrooms are not disturbed. If you run an office near Bickley station, its supply ductwork can gather dust for years before anyone looks inside.

Why act early in Bickley
Leave an AHU uncleaned and the dirt does not 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. For a site in Bickley, fitting the work in overnight now is far easier than closing at short notice later.
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. You will have a fixed price before any work starts.
