How we handle AHU cleaning in Kingsdown
No two plant rooms are the same, from a small ceiling-mounted unit to a large rooftop plant. We look at the unit first, from photos or a site visit, and give you a fixed quote, so you know where you stand. Typical jobs include air handling units never cleaned inside and filters that are clogged or overdue, across filter sections, internal panels and dampers and louvres.
Work in a small place like Kingsdown starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
We’ve been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Landlords, agents and facilities managers
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
How the visit works
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Before we leave, the area is tidied and the paperwork follows. Somewhere like Kingsdown, lanes, gates and parking are worth mentioning in advance.
- The survey covers the unit, its access and how it can be shut down.
- 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.
Getting ready for the visit
- Arrange a key holder or contact on site
- Let us know when the site is closed or quiet
- Mention any sign-in, permit or induction we need
Getting a quote
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.

Different parts, different methods
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. We protect the area below before opening them.
Filters
Filters are the first line of defence in the unit. We check them, and clean or change them as agreed in the quote, and the housing around them is cleaned too.
How we price AHU cleaning
You will get a fixed price before any work starts. It’s based on:
- One-off work versus a regular cycle
- The size of the system
- Site rules, permits and inductions
- Where the site is and how we reach it
Working hours, access and the scale of the site can all change the price. We take each of them into account and give you a fixed price before we start.
What to send for a quote
Photos and a few facts are often enough to price the work. Useful things to send:
- When the site is open and when it’s quiet
- The roof, plant room or outside wall the system runs to
- A few general shots of the system
- Any access panels or hatches you can see
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.
When something else is needed
To be straight with you, there are a few things this work will not fix:
- Coils that are corroded or leaking and need replacing
- Dirty ducts beyond the unit itself
- Controls and BMS settings that run the unit
If you are not sure, just call 0345 646 2711, or send details by email and we will give you a straight answer before booking.
What the work covers
- Filter sections
- Dampers and louvres
- Heating and cooling coils
- Drain trays
- Supply and extract fans
- Internal panels
Common problems we fix in Kingsdown
Dirt in an AHU matters in two ways: the unit supplies the air people breathe, and a dirty unit has to work harder. For anyone working, learning or staying in a building in Kingsdown, that’s air they breathe for hours at a time.
These are the problems we see most often:
- Plant that has been serviced but not cleaned
- Debris and leaves in the fresh air intake
- Dirty fans and fan housings
- Coils clogged with dust and debris
For buildings in and around Kingsdown, TR19® Air cleaning starts with an inspection.
What to look for in a quote
- Whether inaccessible sections are listed on the report
- What paperwork you get at the end
- Exactly which parts of the system are covered
- What insurance they carry
Kingsdown: your questions answered
Can you work in Kingsdown outside opening hours?
Yes, out-of-hours work is a big part of what we do. The work in Kingsdown can fit around your hours. Tell us your opening hours when you ask for a quote.
Can you do AHU cleaning in Kingsdown?
Yes, Kingsdown is within the area we cover across London and the South East. To start, call 0345 646 2711 or send us an email with a few photos of the system.
Do you survey before quoting?
Yes, every time. Diagnosis comes before treatment: the survey shows what needs doing and what access we need, and the quote is based on that.
Can you look after several sites?
Yes. Send the list of sites and the work at each and we’ll quote them together.
Will we get paperwork for the AHU clean?
Yes. You receive a certificate and a report showing each section before and after, with any faults we noticed.
What is TR19?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not law, but it’s the benchmark.
Are you accredited?
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 should I send you?
The site address, the type of premises and your opening hours, along with a few photos and any previous report.
What your team can do, and what needs us
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We will take a look and send you a fixed quote.
Staff cleaning doesn’t 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.
