Ventilation duct cleaning for kitchens and businesses in Castle Hill
TR19® Air is the part of BESA’s TR19® that deals with general supply and extract ventilation. It’s risk-based and inspection-led, so every job starts with a look inside the ducts. The work covers supply ductwork, offices and schools and hospitals and care homes, and common reasons people get in touch are ductwork with too few access panels to clean and ductwork that hasn’t been inspected.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
For insurers and inspectors, the record counts. That is why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Why deal with it now?
In healthcare, care and education settings, ventilation cleaning is hard to put off. Good indoor air starts with a clean system. If the system at a site near Castle Hill fails, there may be nowhere nearby to move to.
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account, and the price is fixed before we start.

What we do, step by step
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. On site, the work takes anything from a single shift for a small office to a planned programme of nights for a large building. Somewhere like Castle Hill, lanes, gates and parking are worth mentioning in advance.
- We look at the system and any earlier reports.
- We inspect the ducts at chosen points to see where cleaning is needed.
- The work area is protected and the system switched off.
- Ducts, grilles and diffusers are cleaned and the debris taken away.
- The report records what was cleaned, anything not reached and a next inspection date.
Preparing for the visit
- Make sure someone can let us in and lock up afterwards
- Dig out any earlier paperwork for the system
- Make sure equipment near the work can be switched off and left to cool

- A system that is not designed to move enough air
- Kitchen extract ductwork, which needs a TR19® Grease clean
Not sure which it is? You can call us on 0345 646 2711 or drop us a line and we’ll tell you honestly before booking.

Common problems we fix in Castle Hill
Planned maintenance tends to focus on fans and filters, not the ducts. Plant can be well serviced while the ductwork goes untouched for years.
Most sites get in touch when they notice something like this:
- Supply ducts with years of dust inside
- Ventilation full of debris from building work
- Poor airflow from the vents
- Systems missing access panels
If you manage a school such as Brenchley and Matfield Church of England Primary School, ventilation cleaning is best booked for the holidays.
What your quote should include
- How VAT is shown on the quote
- What hours they’ll be on site
- What records you will receive afterwards
- Whether they recommend a next date
Looking after it afterwards
Good habits slow the build-up between visits. Our tips:
- Store cleaning certificates where auditors can find them
- Keep vents and grilles clear of shelving and stock
- Get leaks near ductwork fixed quickly
- Do not run the ventilation while builders are sanding or cutting
Keep up with filter changes to protect the ducts. Overdue filters are the quickest way to undo a duct clean.
Regular inspection is the core of TR19® Air. Scheduled inspections spot dust before it becomes a major job.
What the work involves, part by part
Offices and retail
Offices and shops tend to need the work done outside opening hours so staff and customers aren’t disturbed.
Extract ductwork
Extract ducts take air out of toilets, washrooms and general areas. They collect dust, lint and fibres and restrict the flow over time.
Common questions in Castle Hill
Can you come to Castle Hill after we close?
Yes, out-of-hours work is a big part of what we do. It means the site in Castle Hill keeps running as normal. Just call 0345 646 2711 or use the quote form with your opening times and we will plan around them.
Can ventilation in schools around Castle Hill be cleaned out of term?
Yes. Half-terms and the summer break are the natural time for school work. With about 2 schools and colleges on the FSA’s register within roughly a mile and a half of Castle Hill, it pays to plan holiday dates ahead. Booking early in the term gives the best choice of holiday dates.
Does the law say we must follow TR19?
No. TR19® is BESA’s specification, not legislation. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and cleaning to TR19® is the recognised way to show grease is under control.
How do you keep the site clean during the work?
By covering it before any work starts. The work is kept contained and leave the area clean.
Do you have a 24/7 line?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
Can you quote from photos?
Yes, where the photos show enough. If not, a site survey comes first, then a fixed quote.
Who is responsible for fire safety on the premises?
That depends on who controls the premises. The Fire Safety Order 2005 puts the duty on the responsible person, which may be the employer, owner, landlord, facilities manager or managing agent.
How long will the duct cleaning take?
Work on site takes a weekend for a modest system, with large buildings phased floor by floor. We will know more after the survey, and you can give us a ring on 0345 646 2711 or drop us a line to arrange it.
