Part by part
Drain trays
Drain trays can rust and leak over time. We record their condition with photos so repairs can be planned.
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. Cleaning restores the open path through the fins.
How we handle AHU cleaning in Coryton
Our AHU cleaning covers sites in Coryton and the rest of Thurrock, in offices, schools, hospitals, care homes and retail. The work is timed around when the system can be switched off, including evenings, nights and weekends. If you are dealing with plant that needs cleaning after a refit and debris and leaves in the fresh air intake, we can put it right, from dampers and louvres, filter sections and supply and extract fans onwards.
Somewhere as small as Coryton, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
Think of the report as the system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
How do you protect the area?
With sheeting and covers, before anything else happens. We keep the work contained and leave the area clean.
Where does the waste go?
It’s contained and taken away. We collect grease, debris and waste water as we go, so it does not spread.
Do you offer emergency callouts?
Yes. Our emergency line runs 24/7, for problems that can’t wait. Ring any time and tell us what’s happened.
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 a clean will not put right
AHU cleaning can’t fix everything, and we will tell you before we start. It won’t put right:
- The supply and extract ducts, quoted separately
- Ventilation that was badly designed in the first place
- Damaged coils beyond cleaning
Not sure which it is? You can ring 0345 646 2711 or email us and we’ll tell you honestly.
What we work on in Coryton
- Internal panels
- Heating and cooling coils
- Drain trays
- Dampers and louvres
- Supply and extract fans
- Filter sections
Looking after it afterwards
Once we’ve finished, these simple steps help:
- Report stiff or damaged access doors
- Store the TR19 paperwork where auditors can find it
- Book the next check in line with the report
- Note any water around the unit or leaks below it
The report shows each section of the unit before and after, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
What we do, step by step
A visit follows the same order every time: protect the area, make the system safe, do the work, tidy up and leave you the report. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. A few pictures of the system help us make the most of a visit to a place like Coryton.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- 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.
Before we arrive
- Make sure equipment near the work can be switched off and left to cool
- Agree a time when the area can be out of use
- Let us know about permits to work or site inductions
