AHU cleaning for kitchens and businesses in Brasted Chart
An AHU clean is a thorough examination and treatment of the unit. Every section is opened, cleaned and photographed, so the report shows exactly what was done. The work covers drain trays, supply and extract fans and dampers and louvres, and the jobs we see most are units needing a clean before a new tenant or handover and blocked condensate drains and slimy trays.
Many London buildings have had their ventilation extended and altered through several fit-outs, with old runs left behind that are hard to reach. In Brasted Chart, as elsewhere, cleaning starts with an inspection of what’s there.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

Other services in Brasted Chart
Managing agents and facilities teams in Brasted Chart
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 are happy to quote for all of it.
Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
Part by part
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated with your site team.
Drain trays
Condensate from the coil drips into a tray beneath it. Standing water and slime are removed and the outlet is checked.
Questions from Brasted Chart
Do you work at weekends in Brasted Chart?
Yes. We work evenings, overnight and at weekends. That way a site in Brasted Chart does not have to lose a day’s trading. Let us know the hours you’re closed and we will book within them.
Can a school’s ventilation in Brasted Chart be done out of term time?
Yes, and it’s the easiest time to do it. There are about 2 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Brasted Chart. Tell us your holiday dates and we will book the visit for when the site is empty.
Are you accredited?
Our accreditations are CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Do you do ventilation duct cleaning too?
Yes, supply and extract ducts, grilles and diffusers. The survey shows whether the ducts need cleaning now.
Do you look at the system first?
Yes, every time. We diagnose before we treat: the survey shows what needs doing and what access we need and the fixed quote is built on it.
What about areas you cannot get to?
We record them on the report, with a note of where it is, and we tell you what would make it reachable, such as extra access panels in ductwork.
Can we book visits on a schedule?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.
Will you repair the fan or motor?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We’ll flag anything we notice during the clean.
What your team can do, and what needs us
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Leave it or put it right?
Cleaning a unit while it only has light dust is quick. Years of build-up make the job longer and harder, especially where there’s been moisture. In Brasted Chart, as across London, ductwork often passes through shared risers and other people’s space.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we will go through it with you.

What happens on the day
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes from a few hours for a compact unit to a day or more for a large one. Security desks and permits-to-work are routine in London, so let us know what your building in Brasted Chart needs from us.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Getting ready for the visit
- Agree a time when the area can be out of use
- Arrange a key holder or contact on site
- Make sure equipment near the work can be switched off and left to cool
Ask for a quote
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, the quote is fixed before any work is booked.
