Kitchen extract cleaning in WD24: how it works
We treat an extract system much as a doctor treats a patient: diagnose with a survey, treat with a thorough clean, then sign it off. The sign-off is a TR19 certificate with a photo report, issued through the BESCA Vent Hygiene Elite portal. Typical jobs include proof of cleaning requested by an insurer and extraction mentioned at an environmental health visit, across plenums and filters, horizontal duct runs and vertical risers.
The visit has three parts: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with photos. Most of the time goes on the work itself, and that takes one visit for most kitchens, while large or complex systems may need more than one.
- First comes a survey of the whole system, by pictures or a visit.
- Grease readings are taken at set points and you get a fixed quote.
- Once the kitchen has closed and the equipment has cooled, we sheet and protect the area.
- Canopy, plenum, filters, duct runs, risers, fan and discharge are all cleaned to TR19® Grease.
- Readings and pictures are taken again, and you receive a TR19 certificate and photo report.

Kitchen extract cleaning around WD24
Across WD24, from Cassiobury, Woodside and Meriden 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.
London and the South East cover everything from city basements to rural kitchens. The same TR19® standard applies to all of them, in WD24 and beyond.
North Watford: Healthcare kitchens, like those at hospitals such as Watford General Hospital (about 1.8 miles south), often cook for long hours, which puts them in BESA’s heavier-use bands. Church and community hall kitchens, near St Peter's Church or anywhere around North Watford, are easy to forget, but their extracts collect grease like any other.
Part by part
Ductwork and risers
Bends and changes of direction trap more grease than straight runs. Those are among the points where we take readings before and after, so the report shows the difference.
Schools, hospitals and care homes
School, hospital and care home kitchens often have fixed hours and long holidays, so cleans can be planned for holidays or quiet times. The certificate goes straight into the site’s maintenance records.
Signs you need kitchen extract cleaning
A kitchen in WD24 builds up grease in the same places as any other: long horizontal runs, bends, the base of risers and around the fan. Cooler sections of duct collect the most.
Keep an eye out for any of the following:
- Ductwork thick with old, hardened grease
- Proof of cleaning requested by an insurer
- A kitchen with no current TR19 certificate
- Stale cooking odours from the system
What staff can safely do
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That’s our job.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
Aftercare tips
Think of this as the after-treatment advice, in brief:
- Make sure every filter is fitted before cooking
- Keep the TR19 certificate and photo report in the maintenance log
- Empty any grease troughs or cups on the canopy
- Run the extract fan throughout cooking
The kitchen is left clean and ready for the next service. Waste grease and water are contained and removed, and equipment can be switched back on once we’ve gone.
Wipe the canopy down regularly and empty grease troughs or collection points. A daily wipe isn’t a deep clean, but it helps between visits.
Why deal with it now?
Environmental health officers inspect food businesses, in WD24 as everywhere else, and a greasy canopy or dripping filters won’t go unnoticed. A clean extract is one less thing to worry about on the day.

Questions from WD24
Can you look after several sites?
Yes. You deal with one contact for every site in our area, with visits on a regular schedule.
How often should a kitchen extract be cleaned?
Under BESA guidance, the minimum depends on how long you cook each day: every 3 months for 12 to 16 hours, 6 months for 6 to 12 hours and 12 months for 2 to 6 hours. Measured grease levels set the real interval.
What do you need from me for a quote?
Some photos and a quick description of the system, with the address and opening hours. We’ll ask for anything else we need.
What does a TR19 kitchen extract clean include?
We clean every part the grease travels through. Canopy, plenum, filters, ductwork, risers, fan and discharge are all included, reached through access panels where needed.
Is a quote from photos possible?
Yes, for many jobs. Send a few wide pictures plus close-ups of panels, filters or grilles, and we normally come back within one working day. If photos are not enough, we’ll survey first.
Are you accredited for kitchen extract cleaning?
Our work is to BESA TR19® Grease, and we’re a BESCA Vent Hygiene Elite member, with certificates issued through the BESCA portal. Duct Doctor has been trading since 2009.
Do you survey before quoting?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
