AHU cleaning for kitchens and businesses in Ladywell
All the building’s air passes through the fan, so dust on its blades and housing ends up in the airstream. We clean the fan section along with the rest of the unit, once the unit has been shut down and isolated. If you have filters that are clogged or overdue and drain trays holding standing water, we can put it right.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. For a building in Ladywell, dust settles in the units and ducts year after year, which is what TR19® Air cleaning deals with.
For insurers and inspectors, the record counts. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Questions from Ladywell
Do you work at weekends in Ladywell?
Yes. We work evenings, overnight and at weekends. That way a site in Ladywell does not have to lose a day’s trading. When you phone us on 0345 646 2711 or send us an email, mention when the site is quiet.
Can you clean school ventilation in Ladywell during the holidays?
Yes. Half-terms and the summer break are the natural time for school work. With about 45 schools and colleges on the FSA’s register within roughly a mile and a half of Ladywell, it pays to plan holiday dates ahead. Booking early in the term gives the best choice of holiday dates.
When should our AHU next be cleaned?
It depends on the unit, the filters and how the building is used. Inspection tells you when cleaning is needed, and the report recommends a next date.
Do you need to switch the unit off?
Yes, while the clean is under way. We can work evenings, overnight or at weekends so the building isn’t left without ventilation when it’s busy.
Can you set up regular visits?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.
What do you do with what you remove?
It’s contained and taken away. We collect grease, debris and waste water as we go rather than letting it spread.
What accreditations do you have?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
What do you do to protect the area?
Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
The process
There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. Most of the time goes on the work itself, which takes anything from half a day for one small unit to several shifts for a plant room full of them. For a job in Ladywell, tell us about loading bays, permits, lifts and roof access when you book.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Mention any parking or loading restrictions
- Dig out any earlier paperwork for the system
- Let us know when the site is closed or quiet

Ladywell buildings and their air
The FSA’s food hygiene register lists about 45 schools, colleges and universities, about 106 caring premises (care homes, nurseries and hospitals) and about 7 hotels and guest houses with registered kitchens or food service within 1.5 miles or so of the middle of Ladywell. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. University Hospital Lewisham is the nearest hospital, about less than half a mile north-west of Ladywell. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. London plant rooms are often on roofs or in basements reached through occupied floors.
Workplaces around Ladywell station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts. Wherever a school like St Mary's Lewisham Church of England Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

What affects the cost of AHU cleaning
The diagnosis comes before the price. The main factors are:
- Whether it’s a one-off visit or part of a schedule
- What state the system is in
- Site requirements such as sign-in and permits
- Whether several sites go on one quote
We do not list prices on the website, because the cost depends on the site in front of us. For a fixed quote, phone us on 0345 646 2711 or use the quote form, and we will talk you through it.
What to send for a quote
When you call or email, these details help:
- The postcode and the type of business
- Your last certificate, test record or report
- Wide pictures of the system and the area around it
- The times we could work without disrupting the site
Here’s what helps us quote: where the site is, what it is and its opening hours, pictures of the system and the last certificate or report, if there is one. Once you have those, phone us on 0345 646 2711, or email photos.
Staff cleaning versus specialist work
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
Signs you need AHU cleaning in Ladywell
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. Most of it lands at the intake and the first stage of filters, and some travels further into the unit.
If you notice any of these, it’s worth a diagnosis:
- Debris and leaves in the fresh air intake
- Dirty filters cutting the airflow
- Plant that has been serviced but not cleaned
- Dust-coated heating and cooling coils
Healthcare buildings such as University Hospital Lewisham, about within half a mile north-west, depend on their ventilation; if you manage a surgery, clinic or care home near Ladywell, yours matters too.
What your quote should include
- Whether the price is fixed
- When the next visit should be, and why
- How areas they can’t reach will be recorded
- Whether a written report and photos are included
Why act early in Ladywell
Cleaning a unit while it only has light dust is quick. Leave it for years and dirt bakes onto coils and casings, especially where there’s been moisture. A busy site in Ladywell builds up dirt and wear quickly, so putting it off makes the eventual job larger.
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.
