AHU cleaning for kitchens and businesses in Rayners Lane
Our AHU cleaning covers sites in Rayners Lane and the rest of Greater London, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. The work covers internal panels, dampers and louvres and filter sections, and the jobs we see most are air handling units never cleaned inside and air handling units with blocked filters.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so ventilation cleaning in Rayners Lane is normally planned out of hours. Loading and parking are planned with the building first.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Signs you need AHU cleaning in Rayners Lane
Cooling coils create condensation, and that water has to go somewhere. A blocked outlet or a badly sloped tray leaves standing water, and that’s where slime and odours start.
If you notice any of these, it’s worth a diagnosis:
- Units needing a clean before a new tenant or handover
- Coils clogged with dust and debris
- Leaves and litter drawn into the unit
- Odours coming through the supply air
Ventilation work in and around Rayners Lane is risk-based: inspect, then clean what needs it.
Before you book anyone
- If the quote is a fixed price or an estimate
- Whether a written report and pictures are included
- Whether they recommend a next date
- Whether the quote is based on a survey or photos
When something else is needed
An honest diagnosis matters more to us than a booking, so here’s what this work can’t put right:
- A system that’s undersized for the building
- The supply and extract ducts, quoted separately
- Faulty motors, drives or bearings
If in doubt, give us a ring on 0345 646 2711, or send details by email and we will say what we think.
What the work covers
- Supply and extract fans
- Internal panels
- Dampers and louvres
- Filter sections
- Drain trays
- Heating and cooling coils
How the visit works
The visit has three parts: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with pictures. The middle part takes longest, which takes anything from half a day for one small unit to several shifts for a plant room full of them. We fit London jobs around the building rather than the other way round, so a visit in Rayners Lane is typically out of hours.
- 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.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Allow time for equipment near the work to be turned off and cool down
- Mention any parking or loading restrictions
- Find the previous report, if there is one
Getting a quote
To help us quote: where the site is, what it is and its opening hours, pictures of the system and any previous report or certificate. Once you have those, give us a ring on 0345 646 2711 or email us.

For landlords and multi-site operators
We regularly work with managing agents. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.
For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.
What the work involves, part by part
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. They’re cleaned using methods that will not bend or flatten the fins.
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. A clean fan runs more smoothly.
Why it’s worth doing now in Rayners Lane
Stuffy rooms and stale smells in a building in Rayners Lane can sometimes be traced back to the AHU. Cleaning it deals with the cause rather than the symptom. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
We don’t list prices on the website, because each job is priced on what it involves. Call for a fixed quote, and we will talk you through it.
Why us?
- Evenings, overnight and weekends, plus 24/7 emergency callout
- Survey first, then a fixed quote
- Member of BESCA Vent Hygiene Elite, cleaning to BESA TR19® Grease
- A fixed price before any work starts

Rayners Lane: your questions answered
Can you clean school ventilation in Rayners Lane during the holidays?
Yes, out-of-term visits are normal for schools. Around Rayners Lane, the Food Standards Agency lists about 21 schools and colleges with registered kitchens within a mile and a half or so. Booking early in the term gives the best choice of holiday dates.
What do you need to know about parking in Rayners Lane?
Tell us where a van can stop near your site in Rayners Lane, and about any building rules on loading. Night visits tend to make loading easier on London streets.
How much does AHU cleaning cost?
We don’t publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. You get a fixed price before any work starts.
What do you clean inside the unit?
Everything inside the unit that air passes over, from intake to discharge, including coils, fan and drain trays. The photo report shows each section before and after.
Is a quote from photos possible?
In many cases, yes. With good photos, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
Will you repair the fan or motor?
We clean the unit and flag faults rather than repair them, with pictures where it helps.
What does TR19 mean?
BESA’s ventilation hygiene 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.
How often should an air handling unit be cleaned?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. We recommend a next date in each report.
What staff can safely do
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
