About our AHU cleaning in Cryers Hill
Think of an AHU clean as a full check-up for the ventilation. Every section is opened, cleaned and photographed, so the report shows exactly what was done. If you have dust built up on fan impellers and air handling units never cleaned inside, we can put it right.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Think of the report as the system’s health record: dated, with photos, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

What happens on the day
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes one overnight shift for many single units, with bigger plant phased. For a village or hamlet like Cryers Hill, tell us about narrow lanes, gates and parking when you book.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
How to prepare
- Mention any parking or loading restrictions
- Let us know about permits to work or site inductions
- Plan for cooking equipment or plant to be off before we arrive
Getting a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
Advice
AHU cleaning in Cryers Hill: local notes
Food Standards Agency records list about 4 schools, colleges and universities and about 11 caring premises (care homes, nurseries and hospitals) registered as food businesses within roughly a mile and a half of the centre of Cryers Hill. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. We cover Cryers Hill, about 30 miles from central London, as part of our work across London and the South East. Visits are booked around your hours, evenings and weekends included. For Cryers Hill, the closest hospital is Hospital of St John the Baptist, roughly 2.5 miles south. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
If you manage a school such as Great Kingshill Church of England Combined School, ventilation cleaning is best booked for the holidays.

When to call us in Cryers Hill
Air handling units are normally tucked away on roofs, in plant rooms or above ceilings and are rarely seen by anyone but maintenance staff. It’s easy for a long time to go by without anyone opening the panels.
If you notice any of these, it’s worth a diagnosis:
- Dirty filters cutting the airflow
- Debris and leaves in the fresh air intake
- Plant that needs cleaning after a refit
- Units that have only ever had filter changes
Healthcare buildings such as Hospital of St John the Baptist, about 2.5 miles south, depend on their ventilation; if you manage a surgery, clinic or care home near Cryers Hill, yours matters too.
Questions to ask before booking
- What hours they’ll be on site
- Whether a survey comes first
- Whether VAT is included
- Which accreditations they hold, and whether you can check them
Aftercare tips
Results last longer with the right care. We suggest:
- Diary the inspection date recommended in the report
- Keep the area around the fresh air intake clear
- Report musty smells from the vents right away
- Store the TR19 paperwork where auditors can find 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.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
Staff cleaning versus specialist work
Staff cleaning and specialist work are not 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.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
Cryers Hill: your questions answered
Can a school’s ventilation in Cryers Hill be done out of term time?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 4 schools and colleges with food registrations within roughly a mile and a half of Cryers Hill. You can call 0345 646 2711, or send details by email with the dates the site is empty.
Will you come out to Cryers Hill?
Yes. Villages and rural sites across the South East are part of our work, Cryers Hill included. The journey is planned ahead, so a few details about the route help.
How do you protect the area?
With sheeting and covers, before anything else happens. The work is kept contained and clean down when we finish.
Do you clean the ductwork as well?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. Cleaning the unit and ducts together often makes sense, and we can survey both on the same visit.
Do you have insurance?
Yes, we’re fully insured. We also hold CHAS and SafeContractor for clients who vet their contractors.
What does AHU cleaning cost?
It depends on the site, so we quote each one individually. For a quote, call us on 0345 646 2711 or use the quote form with the site type, opening hours and a few photos.
When should our AHU next be cleaned?
It depends on the unit, the filters and how the building is used. Regular inspection shows when it’s due, and we will suggest an interval after the first clean.
What is 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 the work involves, part by part
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. Access is planned during the survey so the quote reflects it.
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. Each section is cleaned from the intake through to the outlet.
