What your team can do, and what needs us
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
TR19 kitchen extract cleaning in Derringstone
Few kitchens can stop cooking for a day so the extract can be cleaned. Cleans are booked for evenings, overnight or weekends, or between services where the kitchen has a gap. With the equipment off and cool and the area sheeted, we clean and hand the kitchen back ready for the next service. Common call-outs are for a TR19 certificate needed for the insurer and extraction mentioned at an environmental health visit, across plenums and filters, discharge points and canopies and hoods. Searching for commercial kitchen extraction cleaning in Derringstone? We’ve been cleaning kitchen extracts across the South East since 2009, with a certificate and photo report after every clean.
A kitchen running fryers and chargrills all day builds up grease much faster than one that mostly steams and boils, so we look at the menu as well as the opening hours when we suggest the next date.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.
Good records are part of the job. You get a written report with photos after every visit, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

When something else is needed
We’d rather tell you now than book work that will not help, so these are the things it won’t cover:
- Damaged duct sections that need replacing
- A canopy that’s too small or a system that was badly designed
- A fan motor that has burnt out
Not sure which it is? You can call 0345 646 2711 or email us and we will tell you honestly.
What the work covers
- Discharge points
- Vertical risers
- Canopies and hoods
- Extract fans
- Plenums and filters
- Horizontal duct runs
What we are called out for in Derringstone
A lot of duct grease gets there because the filters let it through. Damaged, missing or overloaded filters let grease straight past, and it doesn’t stop until it reaches the fan.
What we are most often called out for:
- A TR19 certificate needed for the insurer
- Years of baked-on grease in the ducts
- Extraction mentioned at an environmental health visit
- Missing paperwork after a change of operator
A hospital like Kent and Canterbury Hospital, about 5.3 miles north-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

- Which accreditations they hold, and whether you can check them
- Whether the whole system is included, or only the parts that are easy to reach
- Whether the figure could change on the day
- When they can work, and whether that is outside your opening hours

The process
Each visit runs to the same pattern: sheeting and protection first, make the system safe, do the work, tidy up and leave you the report. On site, the work takes anything from a few hours to a full night, depending on the size of the system. Visits to a village like Derringstone are booked in advance, at a time that suits whoever runs the site.
- Diagnosis comes first, with a survey of the system and how it’s reached.
- Grease readings set the baseline, and a fixed quote follows.
- After the kitchen closes, we sheet the area and set up to contain grease and water.
- The treatment: heavy grease scraped out, then every part degreased to TR19® Grease.
- Then the clean bill of health: readings, a TR19 certificate and a photo report with the next date.
How to prepare
- Tell us where we can park and unload
- Let us know about permits to work or site inductions
- Find the previous report, if there is one

Advice
Derringstone questions
Who is the fire and rescue service for Derringstone?
It’s Kent Fire and Rescue Service, which covers Derringstone. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Who would carry out a food hygiene inspection at a kitchen in Derringstone?
Food hygiene inspections in Derringstone are carried out by Canterbury City council. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
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.
Will I get a certificate after the clean?
You get both a certificate and a photo report. They belong in the maintenance log so they’re to hand when an insurer asks.
What should I send you?
Some photos and a quick description of the system plus the address and your hours. We’ll ask for anything else we need.
Will my insurer ask for a TR19 certificate?
Because a dirty extract can spread a fire through a building. Many insurers require TR19 cleaning, and may refuse or reduce a claim without proof, so keep every certificate.
What accreditations do you hold?
Our work is to BESA TR19® Grease, and we are a BESCA Vent Hygiene Elite member, with certificates issued through the BESCA portal. Duct Doctor has been trading since 2009.
What does a TR19 kitchen extract clean include?
The whole system: canopy inside and out, plenum, grease filters, ductwork, risers, extract fan and discharge, plus attenuators where fitted. Anything we can’t reach is recorded on the report.
For landlords and multi-site operators
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we’re happy to quote for all of it.
Kitchen extract cleaning in Derringstone: the local picture
Look up Derringstone on the FSA’s food hygiene register and you’ll find about 3 restaurants, cafés and canteens within roughly a mile and a half of the centre of Derringstone. Every kitchen in that count with a canopy has a full extract system, canopy to discharge, to keep clear of grease. Environmental health officers from Canterbury City council inspect food businesses in Derringstone. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Before-and-after pictures from each clean are a simple way to show the extract is in hand. Derringstone sits within the area of Kent Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
Bursars and site managers at schools such as Barham Church of England Primary School tend to book extract cleaning for when the kitchen is empty. If you run a church or community hall kitchen, near Church of St John the Baptist or elsewhere in Derringstone, its extract still collects grease from every lunch and event.

Looking after it afterwards
Results last longer with the right care. We suggest:
- Keep the extract on whenever the range is lit
- Keep grease collection points emptied
- Clean the grease filters regularly between TR19 cleans
- Keep to the recommended cleaning interval
You get a photo report after every clean. Before and after photos show each part of the system, alongside a list of what was cleaned, anything out of reach and the recommended next clean date.
Regular filter cleaning is the simplest thing a kitchen can do. A filter that is clean and seated properly stops more grease getting into the plenum, so the ductwork stays cleaner for longer.
Leave it or put it right?
Grease that’s left only gets thicker. BESA guidance says the mean should not go above 200 microns between cleans, and anywhere reaching 500 microns or more needs a spot clean straight away. Heavy build-up takes longer to remove than regular cleans. Systems in rural buildings are often out of sight and out of mind.
