About our AHU cleaning in South Bank
Units vary a lot in size, age and layout, from a small ceiling-mounted unit to a large rooftop plant. We look at the unit first, from photos or a site visit, and send you a fixed quote before any cleaning starts. We are often asked to deal with filters that are clogged or overdue and stale or musty smells from the ventilation, on dampers and louvres, drain trays and internal panels.
London buildings tend to keep their plant on the roof or below ground, so work in South Bank is often done in the evening or at weekends. Parking and loading are agreed with the building in advance.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

Managing agents and facilities teams in South Bank
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements, and we will send a fixed quote.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We are happy to deal with either side, and the report can go to both.
What staff can safely do
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
When to call us in South Bank
Cooling coils create condensation, and that water has to go somewhere. If the drain tray outlet blocks or the tray does not fall properly, water stands in it, and slime and smells soon follow.
What we are most often called out for:
- Filters that are clogged or overdue
- Dust-coated heating and cooling coils
- Debris and leaves in the fresh air intake
- Rooms that smell stuffy when the system runs
Workplaces around London Waterloo station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.

South Bank questions
How do you handle parking and loading in South Bank?
A loading bay, a visitor permit or off-street space near the site in South Bank makes the visit easier to plan. Night visits tend to make loading easier on London streets.
Can the work in South Bank be done at night or at weekends?
Yes, nights and weekends are routine for us. Your customers, staff or residents in South Bank needn’t be disturbed. Your opening times are the first thing we ask for.
Do you need to switch the unit off?
Yes. The fan must be stopped and the unit isolated, and we time the work to suit the site.
Will you repair the fan or motor?
AHU cleaning is what we offer here, not mechanical repairs. Any faults we notice are recorded for your maintenance team to follow up.
Can one contract cover all our sites?
Yes. Tell us the addresses and what each needs and you’ll get one fixed quote.
Can you quote from photos?
Yes, for many jobs. Send wide shots, close-ups of any access panels and anything that worries you, and we typically come back within one working day. Some sites still need a visit, and we’ll say so.
What’s TR19?
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 law, but it’s the benchmark.
What should I send you?
The site address, the type of premises and your opening hours, plus photos of the system and your last certificate or report if you have one.
Fixed quotes for AHU cleaning in South Bank
The diagnosis comes before the price. We look at:
- When the work can happen, such as evenings, overnight or weekends
- Whether it’s a one-off visit or part of a schedule
- Where the site is and how we reach it
- The size of the system
You will not find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll talk you through it.
Helping us quote
You do not need the technical terms. Just send:
- When the site is open and when it’s quiet
- Close-ups of filters, grilles, hatches or access panels
- Problems your staff have spotted
- The paperwork from the last visit, if you have it
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before we start.
The process
We are used to working while the site is closed. 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. Most London sites cannot stop for the day, so work in South Bank is typically done overnight, early in the morning or at weekends.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
How to prepare
- Tell us about site rules, permits or sign-in
- Arrange a key holder or contact on site
- Let us know about parking and loading
Get a fixed quote
Every quote begins with a look at the system, either from photos and details you send or from a site visit. After that, you get a fixed price for the work, before any work starts.

How the job changes from site to site
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. A clean fan runs more smoothly.
Drain trays
Condensate from the coil drips into a tray beneath it. We clear standing water, clean out slime and check the outlet is draining.
