About our AHU cleaning in Newney Green
A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. Common call-outs are for filters that are clogged or overdue and dirty coils holding back the airflow, across dampers and louvres, heating and cooling coils and supply and extract fans.
Somewhere as small as Newney Green, ducted ventilation is usually limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Newney Green buildings and their air
There are about 3 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of central Newney Green. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Newney Green is about 26 miles from central London, well within the area we cover across London and the South East. We work evenings, overnight and at weekends, so the visit fits around the site. The nearest hospital to Newney Green is Chelmsford and Essex Hospital, about 3.2 miles south-east. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
Chelmsford and Essex Hospital, about 3.2 miles south-east, is the nearest hospital to Newney Green, and healthcare sites of every size need their supply air kept clean. If you manage a school such as Hylands School, ventilation cleaning is best booked for the holidays.

Looking after it afterwards
Simple habits between visits make a real difference. We recommend:
- Keep the area around the fresh air intake clear
- Keep the certificate and photo report with the plant records
- Change filters on schedule and log each change
- Don’t ignore odours coming through the grilles
The report shows each section of the unit before and after, and note any part we couldn’t get to. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
What happens on the day
The visit has three parts: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with photos. The middle part takes longest, which takes one overnight shift for many single units, with bigger plant phased. Seeing the system in pictures first means the trip to Newney Green can be planned properly.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
How to prepare
- Name a contact who can let us in at the agreed time
- Clear the space around the work
- Tell us about site rules, permits or sign-in
Ask for a quote
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before work begins.
Advice
What your team can do, and what needs us
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.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
For landlords and multi-site operators
Facilities teams in offices, schools and healthcare sites book us too in Newney Green and across Essex. Work can be phased by floor, building or site to keep disruption down.
Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we will send a fixed quote.
How the job changes from site to site
Drain trays
Condensate from the coil drips into a tray beneath it. Standing water and slime are removed and the outlet is checked.
Filters
Filters are the first line of defence in the unit. As part of the clean, filters are checked and cleaned or replaced as agreed, and clean the filter housing.
What happens if it’s left?
Dirt left in an air handling unit does not stay in the unit. It’s carried through the ductwork and out of the grilles, so cleaning the ducts without the unit only goes so far. Planning a trip to Newney Green ahead is easier for everyone than a rushed one.
We don’t list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll explain what it covers.
