Greater London · Air handling unit cleaning
Air handling unit cleaning in Coombe Hill, Greater London
Looking for AHU cleaning in Coombe Hill? We diagnose first, fix the price and book the work around your hours, then sign off with a report and photos.
- Air handling units due a clean after building work
- Plant that has been serviced but not cleaned
- Odours coming through the supply air
How the visit works
The first job on site is protection: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes half a day to a full day per unit, with large plant planned over several shifts, and we clear up before we go. Loading bays, visitor permits and roof access are the first things we ask about for a site in Coombe Hill.
- We start with a survey of the unit and a fixed quote for the work.
- The unit is shut down with your site team and the area protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Standing water and slime come out of the tray and the drain is checked.
- A TR19® certificate and photo report follow the clean.
Before we arrive
- Make sure equipment near the work can be switched off and left to cool
- Move anything stored near the system
- Dig out any earlier paperwork for the system
Ask for a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before any work starts.
Advice
About our AHU cleaning in Coombe Hill
The fan pushes every bit of air in the system, so dirt on the impeller and housing gets spread around. Fan, housing and the surrounding panels are cleaned as part of the job, with the unit switched off and made safe first. If you are dealing with leaves and litter drawn into the unit and units needing a clean before a new tenant or handover, we can put it right.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so work in Coombe Hill is often done in the evening or at weekends. Parking and loading are agreed with the building in advance.
The sign-off is always in writing: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

What affects the cost of AHU cleaning
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Site requirements such as sign-in and permits
- The times the site is available
- Parking and loading at the site
- Whether it’s a one-off visit or part of a schedule
Working hours, access and the scale of the site all affect the cost. We take each of them into account and give you a fixed price before we start.

A few details help us quote accurately. With your enquiry, please include:
- Your opening hours and when the area is out of use
- The postcode and the type of business
- The roof, plant room or outside wall the system runs to

Quoting starts with a diagnosis, from your photos and details or, where that isn’t enough, a survey on site. Then we send a fixed price, before we start.

Aftercare tips
Here’s the after-treatment advice, in brief:
- Make sure the unit’s access doors open easily
- Report musty smells from the vents right away
- Store the TR19 paperwork where auditors can find it
- Keep the area around the fresh air intake clear
Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.
Why it’s worth doing now in Coombe Hill
Tenants, auditors and owners may want proof that the air handling plant is kept clean. Our certificate and photo report give you clear evidence, for audits, tenants or your own peace of mind. Leaving it on a busy London site only adds to the work.
The price reflects the work, not guesswork. That is why we survey first, from pictures or on site, and the price is agreed before work begins.

Common questions in Coombe Hill
Do you work overnight in Coombe Hill?
Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Coombe Hill needn’t be disturbed. Tell us your opening hours when you ask for a quote.
What do you need to know about parking in Coombe Hill?
A loading bay, a visitor permit or off-street space near the site in Coombe Hill makes the visit easier to plan. Night visits tend to make loading easier on London streets.
How long does it take to clean an air handling unit?
It takes from a few hours for a compact unit to a day or more for a large one. Size, layout and how dirty it is decide the rest, and the quote will give you a clear idea.
Do you work with multi-site operators?
Yes. Send the list of sites and the work at each and we will quote them together.
How do you protect the area?
We start with protection: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
Can you clean the ducts connected to the AHU?
Yes. Ductwork is cleaned through access panels, and any sections we cannot reach are noted in the report, with new panels fitted where needed.
What accreditations do you have?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’ve been trading since 2009 and we’re fully insured.
What do you need from me for a quote?
Where the site is, what it is and when it’s open, along with a few photos and any previous report.
In-house cleaning or a specialist?
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
