AHU cleaning for kitchens and businesses in Malden Rushett
We clean the parts of the unit where dirt and moisture gather: the filter section, heating and cooling coils, drain trays, fan and casing. Every clean comes with a TR19® certificate and before and after pictures in a report. The work covers drain trays, filter sections and supply and extract fans, and people most often call us about leaves and litter drawn into the unit and air handling units never cleaned inside.
Across London, offices, hotels, schools and healthcare buildings rely on mechanical ventilation, much of it supplied through air handling units on roofs or in basements. For a building in Malden Rushett, dust settles in the units and ducts year after year.
Think of the report as the system’s health record: a dated account with photos of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

What we do, step by step
The visit has three parts: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. The middle part takes longest, and that takes a single shift for a typical unit, longer for large or heavily soiled ones. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Malden Rushett.
- 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.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
How to prepare
- Tell us about site rules, permits or sign-in
- Agree a time when the area can be out of use
- Move anything stored near the system
Getting a quote
Here’s what helps us quote: where the site is, what it is and its opening hours, photos of the system and the last certificate or report, if there is one. Then call 0345 646 2711 or drop us a line.

Aftercare tips
No system stays clean for ever, but care slows the build-up. A few tips:
- Keep inspection doors on the unit in good order
- File each AHU report in the maintenance log
- Note any water around the unit or leaks below it
- Report musty smells from the vents straight away
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Record each change in the maintenance log.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
Why it’s worth doing now in Malden Rushett
Facilities teams are often asked for evidence that the ventilation is looked after. Our certificate and photo report give you clear evidence, ready to show anyone who asks. London sites work long hours, and the longer a job is left, the bigger it gets.
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered, and you will get one fixed quote.

What we are called out for in Malden Rushett
No filter stops everything. What gets through settles on coils, fans and the inside of the casing, a little more each month.
If you notice any of these, it’s worth a diagnosis:
- Rooms that smell stuffy when the system runs
- Leaves and litter drawn into the unit
- Units that have only ever had filter changes
- Dust built up on fan impellers
For schools like Chessington Community College, the holidays are the usual time to inspect and clean ventilation.
Questions to ask before booking
- What paperwork you get at the end
- What happens if part of the system can’t be accessed
- Whether the work can be done while the site is closed
- How VAT is shown on the quote
Your questions about AHU cleaning in Malden Rushett
Can the work in Malden Rushett be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Malden Rushett needn’t be disturbed. When you phone us on 0345 646 2711, or email photos, mention when the site is quiet.
What do you need to know about parking in Malden Rushett?
A loading bay, a visitor permit or off-street space near the site in Malden Rushett makes the visit easier to plan. Much of our London work is done overnight, which helps.
Do you do ventilation duct cleaning too?
Yes. We clean supply and extract ductwork to TR19® Air as well. It’s often worth doing both at once, and we can survey both on the same visit.
Can you price the work without visiting?
Yes, if we can see what we need. If not, a site survey comes first, then a fixed quote.
Do you have insurance?
Yes, fully. We also hold CHAS and SafeContractor, for sites that check contractor safety.
How far ahead should we book?
Earlier is better, especially for out-of-hours work. We typically quote within one working day, and there’s a 24/7 line for emergencies.
Do you repair air handling units?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We clean the unit and report anything we see that needs attention.
What do you do to protect the area?
Floors and surfaces near the work are sheeted before any work starts, and anything we remove is contained. Before we leave, we tidy up and clean down.
What affects the cost of AHU cleaning
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether it’s a one-off visit or part of a schedule
- Access, including roofs, risers and ceiling voids
- Any permits to work or inductions
- The condition we find in the survey
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll explain each part.
What to send for a quote
You do not need the technical terms. Just send:
- Your opening hours and when the area is out of use
- A few general shots of the system
- The paperwork from the last visit, if you have it
- Where the plant sits or the system leaves the building, such as a roof or outside wall
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 we can price many jobs without a visit.
Honest limits
We will always give you a straight diagnosis, so here’s what AHU cleaning won’t do:
- The supply and extract ducts, quoted separately
- Breakdowns that need a mechanical engineer
- Coils that are corroded or leaking and need replacing
If in doubt, call us on 0345 646 2711 or drop us a line and we’ll say what we think.
