About our AHU cleaning in Bermondsey
An air handling unit is the heart of a building’s ventilation: air is pulled in, filtered, conditioned and sent out through the ducts. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. We are often asked to deal with fan sections that haven’t been cleaned in years and odours coming through the supply air, across dampers and louvres, heating and cooling coils and supply and extract fans.
London buildings tend to keep their plant on the roof or below ground, so work in Bermondsey 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 dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

AHU cleaning in Bermondsey: local notes
Food Standards Agency data includes about 108 schools, colleges and universities, about 59 hospitals, care homes and childcare premises and about 48 hotels and B&Bs in Bermondsey and the streets around it, up to about 1.5 miles out. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. Many London buildings have had their ductwork altered through several fit-outs, so an inspection comes first. Guy's Hospital is the nearest hospital, about 0.7 miles north-west of Bermondsey. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital.
Healthcare buildings such as Guy's Hospital, about 0.7 miles north-west, depend on their ventilation; if you manage a surgery, clinic or care home near Bermondsey, yours matters too. If you manage a school such as Boutcher Church of England Primary School, ventilation cleaning is best booked for the holidays.
Bermondsey is about 1 mile east of London, in Greater London. For AHU cleaning in and around Bermondsey, please give us a ring on 0345 646 2711, or email photos for a fixed quote.

Common problems we fix in Bermondsey
Cooling coils create condensation, and that water has to go somewhere. A blocked outlet or a badly sloped tray leaves standing water, and slime and smells soon follow.
The symptoms we are asked about most are:
- Condensate trays that will not empty
- Intake sections clogged with outdoor debris
- Filters that are clogged or overdue
- Fan sections that haven’t been cleaned in years
If you manage offices or shops near London Bridge station, their ventilation can be inspected and cleaned out of hours.
Questions to ask before you book
- Which accreditations they hold, and whether you can check them
- Whether the price is fixed
- How areas they can’t reach will be recorded
- What hours they’ll be on site
Why deal with it now?
A slimy drain tray only gets worse. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Dealing with it early keeps the clean straightforward. A building in Bermondsey may have flats or offices above and alongside, and a fault in the system can affect them too.
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before work begins.

What staff can safely do
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.
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
Common questions in Bermondsey
Can you work in Bermondsey outside opening hours?
Yes, nights and weekends are routine for us. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
Is parking a problem for work in Bermondsey?
A loading bay, a visitor permit or off-street space near the site in Bermondsey makes the visit easier to plan. Working overnight, as we often do in London, usually makes it simpler.
Where does the waste go?
It leaves the site with us when we go. During the work, it’s contained so the area stays clean.
Does the AHU have to be shut down for cleaning?
Yes, for the time we’re working on it. Out-of-hours work is available so the building is not left without ventilation when it’s busy.
What if parts of the system cannot be reached?
Anything we can’t reach goes on the report, with a note of where it is, and we explain what access is needed, such as extra access panels in ductwork.
Can you come out in an emergency?
Yes. Our emergency line runs 24/7 for anything that can’t wait until a planned visit. Call us any time and explain what’s happened.
Can one contract cover all our sites?
Yes. Send the list of sites and the work at each and we will quote them together.
How often should an air handling unit be cleaned?
That is set by inspection, in line with TR19® Air. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
Aftercare tips
Simple habits between visits make a real difference. We recommend:
- Keep inspection doors on the unit in good order
- Change filters on schedule and log each change
- Diary the inspection date recommended in the report
- Watch for drips or damp patches near the plant
Restart the unit with your site team or maintenance contractor once we have finished. Check the drain tray is emptying over the first few days to make sure it stays clear.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
What happens on the day
Everything the job needs comes with us, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. Night and weekend working is normal for us in London, and a site in Bermondsey is no exception.
- We look at the unit and the plant area during the survey.
- 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.
Before we arrive
- Let us know when the site is closed or quiet
- Dig out any earlier paperwork for the system
- Move anything stored near the system
How to get a quote
Every quote begins with a look at the system, from your pictures and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work, before any work starts.

What affects the quote in Bermondsey
There’s no set price list, because no two systems are the same. The quote depends on:
- Whether we need access equipment or extra panels
- How big the system is
- Whether several sites go on one quote
- One-off work versus a regular cycle
What you pay reflects the actual work. That’s why every job is surveyed first, and why the quote is fixed before we start.
What to send for a quote
Many jobs can be priced from pictures and some basics. Useful things to send:
- Any access panels or hatches you can see
- Photos showing the whole system and its surroundings
- Any previous report or certificate
- 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.
What AHU cleaning cannot fix
It’s worth knowing the limits before booking:
- Damaged coils beyond cleaning
- Ductwork downstream of the unit, which is a separate clean
- Faulty motors, drives or bearings
If in doubt, give us a ring on 0345 646 2711 or drop us a line and we’ll say what we think.
