Our kitchen extract cleaning service in DA4
Duct Doctor has been cleaning kitchen extract systems since 2009. As a BESCA Vent Hygiene Elite member, we clean to BESA TR19® Grease, and we are fully insured, with CHAS, SafeContractor and ISO 9001. The work covers plenums and filters, canopies and hoods and vertical risers, and common reasons people get in touch are stale cooking odours from the system and poor airflow at the canopy.
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. You only need to give us clear access and switch off what needs to be off. The visit takes as long as the system needs, from a few hours to several planned visits.
- You send pictures or we visit, and the system is surveyed from canopy to discharge.
- Grease thickness is measured and the price is fixed before work starts.
- The kitchen is closed, the equipment cooled and everything nearby protected.
- Filters, canopy and plenum are cleaned, then the ducts, risers, fan and discharge.
- We re-test, photograph and send your certificate and photo report.

Around Sutton at Hone
We work in commercial kitchens and buildings around Darenth Country Park, The Greyhound pub and Leigh Academy and the streets around them. Other local landmarks include Church of St John the Baptist (under half a mile north-west) and Sutton-At-Hone Church of England Primary School (under half a mile north). The closest station to Sutton at Hone is Farningham Road station, roughly 0.5 miles south.

Kitchen extracts across DA4
Across DA4, from Sutton at Hone, South Darenth and Farningham outwards, kitchens range from town-centre restaurants and takeaways to pubs, hotels, schools and care homes. Each extract is cleaned to the same TR19® standard, canopy to discharge.
In England, the Fire Safety Order puts the duty on the responsible person to assess and reduce fire risk, and each certificate and photo report is a record you can keep in your log book.
Sutton at Hone: Healthcare kitchens, like those at hospitals such as Darenth Park Hospital (about 2 miles north-east), often cook for long hours, which puts them in BESA’s heavier-use bands. If you look after a school kitchen, at a school such as Sutton-At-Hone Church of England Primary School or anywhere near Sutton at Hone, the holidays are the usual time for a TR19® clean.
What the work involves, part by part
Extract fan and discharge
The fan pulls the air through the whole system, and grease that gets past everything else ends up on its blades. We isolate it, open it up and degrease it.
Restaurant and pub kitchens
Grills, fryers and woks send a lot of fat into the extract, and measured readings show whether the minimum interval is enough.
Managing agents and facilities teams in DA4
Whether it’s one building or many, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
We also work for facilities teams across offices, schools and healthcare in DA4 and across Kent. Work can be phased by floor, building or site around the people who use them.
Why it fails
It’s common for parts of a duct to have been missed for years. Most of the time it’s because there were never enough access panels, so nobody could get to them. Grease in those sections keeps building out of sight.
Look out for any of the following:
- Extraction mentioned at an environmental health visit
- Cleaning needed before an insurance renewal or survey
- A system with no record of a TR19 clean
- Poor airflow at the canopy
Leave it or put it right?
Any food business in DA4 can expect visits from the council’s environmental health officers, and they look at the cleanliness of the premises and equipment, extraction included. Keeping the extract clean helps the whole kitchen pass muster.
Questions to ask before booking
- What paperwork you get at the end
- Whether the price is fixed
- Whether the work can be done while the site is closed
- Whether VAT is included
When something else is needed
We’d rather tell you now than book work that won’t help, so these are the things it will not cover:
- A grease trap that needs emptying
- Ductwork that is corroded, split or leaking (that is for a ductwork contractor)
- A canopy that is too small or a system that was badly designed
DA4 questions
How much notice do you need?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
What should I send you?
Only a few details: the address, the site type, your opening hours and how we reach the system. Photos and any previous paperwork make it quicker. After that, simply call us on 0345 646 2711 or drop us a line.
Where does the waste go?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. None of it is left on site.
Which sectors do you work in?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
What if parts of the system cannot be reached?
Anything we can’t reach goes on the report, with a note of where it is, and we explain what access is needed, for example new access panels.
Will the clean disrupt our service?
We clean while the kitchen is closed, working evenings, overnight or at weekends to suit you. We need the equipment switched off and cooled first.
What does TR19 mean?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
