Ventilation duct cleaning for kitchens and businesses in Throcking
Toilet, washroom and general extract ducts gather dust, fluff and debris. Supply ducts carry anything the filters miss. Both are cleaned, with the area protected and the mess contained. The work covers offices and schools, toilet extract systems and grilles and diffusers, and common reasons people get in touch are odours carried round the building by the ducts and extract ducts clogged with lint and dust.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

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. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
Throcking questions
Do you work at weekends in Throcking?
Yes, nights and weekends are routine for us. That way a site in Throcking does not have to lose a day’s trading. When you ring 0345 646 2711 or drop us a line, mention when the site is quiet.
Is Throcking within the area you cover?
Yes, smaller places are covered as well as towns. A survey first, from pictures or a visit, means we arrive with the right kit.
What happens if parts of the ductwork cannot be reached?
Nothing is hidden: any section we couldn’t get into is listed. We can install panels to open those sections up.
What types of premises do you cover?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
Can you come out in an emergency?
Yes, day and night, every day of the year. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
Which accreditations do you hold?
Our accreditations are CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Is TR19 a legal requirement?
No. TR19® is BESA’s specification, not legislation. The legal duty comes from the Regulatory Reform (Fire Safety) Order 2005: the responsible person must assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.
Where does the waste go?
We take it away when we go. While we work, it’s kept contained to keep the area clean.

Different parts, different methods
Grilles and diffusers
Every duct ends at a grille or diffuser in the room. They’re cleaned along with the ductwork, so the room side matches the duct side.
Supply ductwork
Supply runs are inspected at set points first to see where cleaning is needed.
Honest limits
A few issues sit outside what this work can do:
- Building management settings that run the plant
- Damaged ductwork beyond cleaning
- Leaks from roofs, pipes or walls into the ductwork
