About our AHU cleaning in Southend-on-Sea
An AHU clean is a thorough examination and treatment of the unit. We look inside each section, clean what we find and record it with pictures, so the report shows exactly what was done. The work covers supply and extract fans, internal panels and drain trays, and people most often call us about air handling units due a clean after building work and coils clogged with dust and debris.
Work in occupied buildings in Southend-on-Sea is planned around the people using them, so it’s phased floor by floor or done out of hours.
A written report with photos follows each visit, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Between visits
Here’s the after-treatment advice, in brief:
- File each AHU report in the maintenance log
- Note any water around the unit or leaks below it
- Do not ignore odours coming through the grilles
- Stick to the filter change plan
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.
Make the drain tray part of every maintenance visit. A drain that’s cleared early never gets to the slime stage.
FAQs for Southend-on-Sea
Can you clean school ventilation in Southend-on-Sea during the holidays?
Yes. Half-terms and the summer break are the natural time for school work. There are about 17 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Southend-on-Sea. Send us your term dates when you give us a ring on 0345 646 2711 or drop us a line, and we will fit the work in.
Is AHU cleaning available in Southend-on-Sea?
Yes. We work across London and the South East, and Southend-on-Sea is part of that. A fixed quote usually follows within one working day of the survey details.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
What if parts of the system can’t be reached?
Anything we can’t reach goes on the report, with pictures where possible, and we explain what access is needed, for example new access panels.
Is a quote from photos possible?
Yes, where the pictures show enough. If not, a site survey comes first, then a fixed quote.
What should I send you?
Some pictures and a quick description of the system plus the address and your hours. If we need more, we will ask.
Do you repair air handling units?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We’ll flag anything we notice during the clean.
How do you keep the site clean during the work?
With sheeting and covers, before anything else happens. The work is kept contained and clean down when we finish.
Why it’s worth doing now in Southend-on-Sea
A slimy drain tray only gets worse. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Dealing with it early keeps the clean straightforward. Larger sites in Southend-on-Sea are easier to manage on a planned schedule.
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account and give you a fixed price before any work starts.

Multi-site and managed buildings
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
In-house cleaning or a specialist?
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.
Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Different parts, different methods
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. A clean gets air moving through the coil properly again.
Internal casing and panels
Access doors and panels are opened in turn and closed properly afterwards before the unit is handed back.
How the visit works
Night work is normal for us. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. The visit itself takes one overnight shift for many single units, with bigger plant phased. In the busier parts of Southend-on-Sea, parking and roof access are the main things to plan.
- 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.
Preparing for the visit
- Clear loose items from the work area
- Let us know about parking and loading
- Mention any sign-in, permit or induction we need

Quoting starts with a diagnosis, from your pictures and details or, where that isn’t enough, a survey on site. Then we send a fixed price so you know the cost before work begins.
