Winchmore Hill kitchens: local notes
The FSA’s food hygiene register includes about 5 pubs, bars and clubs in and around Winchmore Hill, up to about a mile and a half out. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Environmental health officers from Buckinghamshire council inspect food businesses in Winchmore Hill. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Keeping each certificate and photo report on file helps show the extract is looked after. Winchmore Hill sits within the area of Buckinghamshire Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Amersham Hospital is the nearest hospital to Winchmore Hill, about 1.7 miles north-east. A hall kitchen that only cooks for events, whether near Church of All Saints or elsewhere in Winchmore Hill, still needs its extract cleaned, just less often.

About our kitchen extract cleaning in Winchmore Hill
The ducts are where most of the grease hides. We reach horizontal runs and vertical risers through access panels, scraping heavy deposits by hand before degreasing. Anything out of reach is noted in the report, and new panels can be fitted. The work covers discharge points, vertical risers and extract fans, and the jobs we see most are grease smells coming from the extract and a system with no record of a TR19 clean. Need a TR19 duct cleaning contractor for Winchmore Hill? We’ve been cleaning kitchen extracts across the South East since 2009, as a BESCA Vent Hygiene Elite member.
What can be cleaned depends on what can be reached. Where a duct run has no panels, we say so on the report and can fit new ones.
Work in a small place like Winchmore Hill starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
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 act early in Winchmore Hill
Grease build-up causes everyday problems too. Filters block, airflow drops and the kitchen gets hotter and smokier, while the fan works harder to move less air. Grease drips, smells and condensation are common next. With notice, the visit to Winchmore Hill can be fitted around your bookings and events.
You will not find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we’ll explain what it covers.

What else we do in Winchmore Hill
Common problems we fix in Winchmore Hill
It’s common for parts of a duct to have been missed for years. The usual reason is a lack of access panels, so nobody could get to them. Grease in those sections keeps building out of sight.
Most sites get in touch when they notice one of these:
- A new tenancy or takeover with no cleaning history
- Grease drips onto cooking equipment
- An extract that has never been cleaned to TR19
- Heavy grease build-up inside the duct runs
If you look after a school kitchen, at a school such as Coleshill Church of England Infant School or anywhere near Winchmore Hill, the holidays are the usual time for a TR19® clean.

Winchmore Hill questions
Will you come out to Winchmore Hill?
Yes. Winchmore Hill is within the area we cover across London and the South East. The journey is planned ahead, so a few details about the route help.
Do you do school kitchen extract cleaning in Winchmore Hill in the summer holidays?
Yes, out-of-term visits are normal for schools. There are about 2 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Winchmore Hill. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Which parts of the extract do you clean?
All of it, from the canopy through to the discharge. Sections with no access are listed on the report, and extra panels can be fitted.
Are you accredited for kitchen extract cleaning?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.
Do I have to clean my extract to TR19 by law?
TR19® itself is not law. Under the Fire Safety Order 2005, the responsible person must assess and reduce fire risk, and cleaning to TR19 is the recognised way to show you’ve dealt with extract grease.
Where does the waste go?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. None of it is left on site.
Do you look at the system first?
Yes. Every job is surveyed first, either from pictures and details you send or on a site visit. Then you get a fixed quote.
How often does a kitchen extract system need cleaning?
That comes down mainly to daily cooking hours. Heavy use of 12 to 16 hours a day calls for a clean at least every 3 months under BESA guidance, and lighter use less often. We’ll recommend a date after measuring the grease.
Part by part
Canopy and plenum
The plenum is out of sight behind the filters, so it’s easy to forget. We take the filters out and clean the plenum and housing thoroughly.
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.
Honest limits
Kitchen extract cleaning can’t fix everything, and we’ll tell you before we start. It doesn’t solve:
- A grease trap that needs emptying
- A fan motor or bearings that have failed (that needs a fan repair or replacement)
- Fire dampers that won’t close (that needs damper testing and remedials)
Not sure which it is? You can ring 0345 646 2711, or send details by email and we will tell you honestly before you book.
What the work covers
- Vertical risers
- Horizontal duct runs
- Extract fans
- Plenums and filters
- Discharge points
- Canopies and hoods
Aftercare tips
No system stays clean for ever, but care slows the build-up. Our tips:
- Never cook with filters missing or out of place
- Book the next clean before the date on the report
- Flag any change in how the extract sounds or works
- Keep the TR19 certificate and photo report in the maintenance log
Every clean ends with a photo report. It shows the system before and after, part by part, and lists what was cleaned, any areas we couldn’t reach and the date the next clean is due.
Clean the grease filters often, not just on clean day. A filter that is clean and seated properly stops more grease getting into the plenum, which slows build-up further down the system.
What affects the cost of kitchen extract cleaning
Your quote is based on your site. We consider:
- The size of the system
- Working hours and out-of-hours timing
- Where the site is and how we reach it
- One-off work versus a regular cycle
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we will go through it with you.
What to send for a quote
What to send for a quote:
- The roof, plant room or outside wall the system runs to
- Any access panels or hatches you can see
- When the site is open and when it’s quiet
- Wide pictures of the system and the area around it
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.
What we do, step by step
Everything the job needs comes with us, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. The visit takes as long as the system needs, from a few hours to several planned visits. The timing of a visit to Winchmore Hill is set by you, and the travel is our side of the planning.
- We survey the system first, from your photos and details or on a site visit.
- We measure the grease at set points along the system, then give you a fixed price.
- With the kitchen closed and equipment off and cool, the area is sheeted.
- Canopy, plenum, filters, duct runs, risers, fan and discharge are all cleaned to TR19® Grease.
- Finally the system is re-tested and photographed, and the certificate and report follow.
