Elsenham AHU cleaning
AHU cleaning for commercial sites in Elsenham and across Essex. BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease.
- Dirty filters cutting the airflow
- Units needing a clean before a new tenant or handover
- Debris and leaves in the fresh air intake
For landlords and multi-site operators
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side and send the paperwork to whoever needs it.
Keeping records across a portfolio is half the battle. Every visit ends with a dated report and photos, ready to show insurers, fire officers or EHOs.
AHU cleaning in Elsenham, done properly
Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins are not flattened. Typical jobs include dirty filters cutting the airflow and dust built up on fan impellers, on supply and extract fans, dampers and louvres and filter sections.
Visits to a place like Elsenham are fitted around opening hours. The method doesn’t change: inspect first, clean, then record what was done.
A written report with photos follows every visit, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

How it works
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool first, and the area around the work is covered and protected. On site, it takes half a day to a full day per unit, with large plant planned over several shifts. For a site near Elsenham, the work is booked around your opening hours, evenings and weekends included.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Before we arrive
- Clear loose items from the work area
- Make sure someone can let us in and lock up afterwards
- Let us know how we reach the system, including roofs, risers and plant rooms

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, particularly where damp has made it stick. It’s easy to lose track of when the work was last done on a quieter site.
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote and give you a fixed price before we start.

AHU cleaning around Elsenham
The FSA’s food hygiene register lists about 4 schools, colleges and universities with registered kitchens or food service across Elsenham and its immediate surroundings (about a mile and a half). Where buildings like these have air handling units, filters, coils and drain trays need regular attention. About 4.1 miles south-west of Elsenham is Herts and Essex Hospital, the nearest hospital. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. About 32 miles out from central London, Elsenham is part of the South East area we work across. Evening, overnight and weekend visits are all possible.
Healthcare ventilation, from large hospitals like Herts and Essex Hospital (about 4.1 miles south-west) to small clinics, depends on clean filters, coils and ducts. If you run an office near Elsenham station, its supply ductwork can gather dust for years before anyone looks inside. If you manage a school such as Forest Hall School, ventilation cleaning is best booked for the holidays.

How the job changes from site to site
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. We plan safe access as part of the survey so the quote reflects it.
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. We clean each section from intake to discharge.
Between visits
No system stays clean for ever, but care slows the build-up. A few tips:
- Check the drain tray is emptying during routine visits
- Note any water around the unit or leaks below it
- Flag stale or damp smells in the supply air
- Report stiff or damaged access doors
Restart the unit with your site team or maintenance contractor once we have finished. Keep an eye on the condensate drain over the next few days to confirm water is draining away.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
What staff can safely do
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
