How we handle AHU cleaning in North Cray
We clean air handling units for buildings in North Cray and across Greater London, working to TR19® Air, in offices, schools, hospitals, care homes and retail. Units are cleaned when the site can spare them, often evenings, overnight or weekends. If you are dealing with dirty fans and fan housings and plant that has been serviced but not cleaned, we can put it right, from heating and cooling coils, dampers and louvres and drain trays onwards.
Across London, offices, hotels, schools and healthcare buildings rely on mechanical ventilation, much of it supplied through air handling units on roofs or in basements. For a building in North Cray, dust settles in the units and ducts year after year.
The paperwork matters as much as the work. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

More services for North Cray
Do you need AHU cleaning in North Cray?
Air handling units are normally tucked away on roofs, in plant rooms or above ceilings and are rarely seen by anyone but maintenance staff. Months can pass without anyone looking inside.
The symptoms we’re asked about most include:
- Air handling units never cleaned inside
- Debris and leaves in the fresh air intake
- Units needing a clean before a new tenant or handover
- Dirty filters cutting the airflow
Classrooms and halls at schools such as Royal Park Primary Academy are easiest to work in when pupils are away.

North Cray questions
Do you work at weekends in North Cray?
Yes. We work evenings, overnight and at weekends. It means the site in North Cray keeps running as normal. Tell us your opening hours when you ask for a quote.
Does London parking affect a job in North Cray?
A loading bay, a visitor permit or off-street space near the site in North Cray makes the visit easier to plan. Working overnight, as we often do in London, usually makes it simpler.
Do you work in North Cray?
Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, and that includes North Cray.
Do you do ventilation duct cleaning too?
Yes. Ductwork is cleaned through access panels, with anything inaccessible recorded, and new panels can be fitted.
Can you look after several sites?
Yes. Tell us the addresses and what each needs and we’ll quote them together.
What is TR19?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
How much does AHU cleaning cost in North Cray?
We don’t publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before we start.
What do you do with what you remove?
It’s contained and taken away. We collect grease, debris and waste water as we go rather than letting it spread.
What your team can do, and what needs us
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
What AHU cleaning can’t fix
AHU cleaning can’t fix everything, and we will tell you before any work starts. It does not solve:
- Building management system faults
- A system that’s undersized for the building
- Leaking heating or cooling coils
If you are not sure, just give us a ring on 0345 646 2711 or send us an email and we will give you a straight answer before you book.
What we work on in North Cray
- Dampers and louvres

For landlords and multi-site operators
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.

The process
We start by comparing what we find with the survey or your pictures. If anything is different, we talk it through with the person on site before carrying on. From there, it takes anything from half a day for one small unit to several shifts for a plant room full of them. Security desks and permits-to-work are routine in London, so let us know what your building in North Cray needs from us.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before photos of each section of the unit.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after pictures and issue the certificate and report.
Preparing for the visit
- Mention any sign-in, permit or induction we need
- Move anything stored near the system
