AHU cleaning for kitchens and businesses in Abbey Wood
Think of an AHU clean as a full check-up for the ventilation. Every section is opened, cleaned and photographed, so the report shows exactly what was done. Typical jobs include units needing a clean before a new tenant or handover and units that have only ever had filter changes, on filter sections, internal panels and heating and cooling coils.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so ventilation cleaning in Abbey Wood is typically planned out of hours. Parking and loading are agreed with the building in advance.
The report is your system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

What we are called out for in Abbey Wood
Filters catch most of the dust, but not all of it. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
Look out for these warning signs:
- Condensate trays that won’t empty
- Fan sections that haven’t been cleaned in years
- Units needing a clean before a new tenant or handover
- Air handling units never cleaned inside
If you run an office near Abbey Wood station, its supply ductwork can gather dust for years before anyone looks inside.

FAQs for Abbey Wood
What do you need to know about parking in Abbey Wood?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Working overnight, as we often do in London, typically makes it simpler.
Do you work at weekends in Abbey Wood?
Yes, we can come after you close and finish before you open. It means the site in Abbey Wood keeps running as normal. Tell us your opening hours when you ask for a quote.
Do you work with multi-site operators?
Yes. We work across South East England and London, so we can schedule a run of sites on one programme. Every site has its own report.
Are you accredited?
We hold CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
What if parts of the system cannot be reached?
The report shows them clearly. In ductwork, new access panels are often the answer, and we can fit those.
What information do you need?
The site address, the type of premises and your opening hours, plus pictures of the system and your last certificate or report if you have one.
How often should an air handling unit be cleaned?
There’s no single answer; it comes down to the building and the unit. Regular inspection shows when it’s due, and we will suggest an interval after the first clean.
What happens to the waste?
It’s contained and taken away. We collect grease, debris and waste water as we go rather than letting it spread.
When it’s something else
To be straight with you, there are a few things this work won’t fix:
- Controls and BMS settings that run the unit
- Damaged coils beyond cleaning
- Ventilation that was badly designed in the first place
If you are not sure, just give us a ring on 0345 646 2711, or send details by email and we’ll give you a straight answer.

For Abbey Wood, the closest hospital is Bexley Hospital, roughly 2.2 miles south-east. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.

How it works
Your trading hours come first. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes half a day to a full day per unit, with large plant planned over several shifts. Managed blocks in London often need contractors booked in ahead, and we’re happy to deal with the agent directly for a site in Abbey Wood.
- We start with a survey of the unit and a fixed quote for the work.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- We close up the unit and send the certificate and before and after photos.
Getting ready for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Tell us about site rules, permits or sign-in
- Tell us the best time to work, such as after service or at a weekend
Getting a quote
For a fixed quote, call us on 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. We typically come back within one working day.
Advice
What staff can safely do
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That’s our job.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.

Why deal with it now?
Dirt left in an air handling unit does not stay in the unit. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. For a site in Abbey Wood, fitting the work in overnight now is far easier than closing at short notice later.
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will explain each part.

Keeping the system healthy
Simple habits between visits make a real difference. Our advice:
- Watch for drips or damp patches near the plant
- Keep the area around the fresh air intake clear
- Keep inspection doors on the unit in good order
- Check the drain tray is emptying during routine visits
If the ductwork hasn’t been cleaned, consider it next. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
What affects the cost of AHU cleaning
The price is fixed before any work begins. It takes into account:
- Whether several sites go on one quote
- Access, including roofs, risers and ceiling voids
- What state the system is in
- Where the site is and how we reach it
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you’re not sure what’s needed, call us on 0345 646 2711 or use the quote form for straight advice and a fixed quote.
What to send for a quote
We can often survey from photos. The most useful are:
- Problems your staff have spotted
- Where the site is and what kind of site it is
- A few general shots of the system
- The roof, plant room or outside wall the system runs to
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.
