AHU cleaning for kitchens and businesses in Strawberry Hill
Every supply and extract system relies on the air handling unit at its centre: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Anything that collects inside the unit can end up in the rooms it serves, so cleaning the unit matters as much as cleaning the ducts. Common call-outs are for plant that has been serviced but not cleaned and drain trays holding standing water, on supply and extract fans, filter sections and drain trays.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. In a building in Strawberry Hill, dust and debris build up in the units and ductwork over time, which is what TR19® Air cleaning deals with.
We’ve been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

FAQs for Strawberry Hill
What do you need to know about parking in Strawberry Hill?
A loading bay, a visitor permit or off-street space near the site in Strawberry Hill makes the visit easier to plan. Working overnight, as we often do in London, typically makes it simpler.
Can the work in Strawberry Hill be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Just call 0345 646 2711 or use the quote form with your opening times and we’ll plan around them.
Which parts of an air handling unit do you clean?
All the internal parts the air touches, from the intake and filters through the coils and fan to the outlet. You get a photo report showing each part before and after.
Are you insured?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
How much does AHU cleaning cost in Strawberry Hill?
Size, condition, access and working hours all affect the cost. Call for a fixed quote, normally ready within one working day.
Can you price the work without visiting?
Yes, where the pictures show enough. If not, a site survey comes first, and the quote follows that.
Which sectors do you work in?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
Can one contract cover all our sites?
Yes. Our area covers London and the South East, so we can schedule a run of sites on one programme. Each site gets its own report and pictures.
Keeping the system healthy
Results last longer with the right care. We suggest:
- Make sure condensate is draining away
- Report stiff or damaged access doors
- Keep the certificate and photo report with the plant records
- Keep filter changes on time and recorded
The report shows each section of the unit before and after, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.
The process
Protection comes first: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. It takes a single shift for a typical unit, longer for large or heavily soiled ones, and we clear up before we go. Before any visit in Strawberry Hill, we agree where the van can stop and how equipment reaches the system.
- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after photos and issue the certificate and report.
How to prepare
- Let us know about permits to work or site inductions
- Have your last certificate or report to hand
- Agree a time when the area can be out of use

What affects the quote in Strawberry Hill
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Where the site is and how we reach it
- Site rules, permits and inductions
- Working hours and out-of-hours timing
- Whether it’s a one-off visit or part of a schedule
We do not list prices on the website, because the cost depends on the site in front of us. For a fixed quote, give us a ring on 0345 646 2711 or email us, and we’ll talk you through it.
What we need to know
When you contact us, these details help:
- Your last certificate, test record or report
- How we’d reach plant on a roof or in a plant room
- When the site is open and when it’s quiet
- A few general shots of the system
Here’s what helps us quote: the address, the type of site and when it’s open, pictures of the system and the last certificate or report, if there is one. Once you have those, ring 0345 646 2711 or email us.
Multi-site and managed buildings
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
Whether it’s one building or many, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with photos.
Common problems we fix in Strawberry Hill
Mechanical servicing keeps a unit running, but it doesn’t always include cleaning the inside. So a unit can be well maintained and still dirty.
Clients typically contact us after spotting one of these:
- Filters that are clogged or overdue
- Blocked condensate drains and slimy trays
- Rooms that smell stuffy when the system runs
- Debris and leaves in the fresh air intake

What staff can safely do
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
