Kitchen extraction cleaning in Blackfen
Kitchen extract cleaning for Blackfen, with a survey first and a report with pictures at the end. Call for a fixed quote.
- A system with no record of a TR19 clean
- A smoky, hot kitchen with weak extraction
- Years of baked-on grease in the ducts
Between visits
No system stays clean for ever, but care slows the build-up. A few tips:
- Tell us when the extract starts to drip or smell
- File each certificate with the fire risk assessment
- Keep the baffle filters clean
- Keep to the recommended cleaning interval
You leave with a date for the next clean, set from your daily cooking hours and the readings we took. We can put the system on a 3, 6 or 12-monthly plan, so the date is not missed.
Run the extract whenever the kitchen is cooking. Switching it off early leaves vapour to settle on the canopy and plenum, and the next clean has more to do.
Kitchen extract cleaning in Blackfen, done properly
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. We are often asked to deal with an inspection that picked up a dirty extract and grease drips onto cooking equipment, across discharge points, horizontal duct runs and extract fans. Extraction cleaning, hood cleaning and TR19 duct cleaning all end up in the same place: a system that’s clean inside, not just on the surface, and a certificate that proves it.
Most kitchens in Blackfen fall into one of BESA’s three bands: every 3 months for 12–16 hours, every 6 months for 6–12 hours and every 12 months for 2–6 hours, adjusted by what the grease readings show.
Across London, many commercial kitchens are squeezed into basements and narrow back-of-house spaces, and the duct may run up through several floors before it discharges at the roof. In Blackfen, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
For insurers and inspectors, the record counts. That is why every job is written up in a report with photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Other services in Blackfen
Different parts, different methods
Canopy and plenum
Whether it’s one hood or a long island canopy, each section is cleaned and photographed before and after.
Restaurant and pub kitchens
Restaurants and pubs tend to cook long hours with plenty of frying and grilling, so their cleaning interval is often 3 or 6 months under BESA guidance. We clean after close or before opening.
Why act early in Blackfen
TR19® is not law, but the Regulatory Reform (Fire Safety) Order 2005 is. It puts a duty on the responsible person to assess and reduce fire risk, which in a kitchen includes the grease in the extract. Cleaning to TR19 is the recognised way to show you’ve done it. Leaving it on a busy London site only adds to the work.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you’re not sure what’s needed, call 0345 646 2711, or email photos for straight advice and a fixed quote.

Blackfen questions
Who carries out food hygiene inspections in Blackfen?
Food hygiene inspections in Blackfen are carried out by Greenwich council. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Can you work in Blackfen outside opening hours?
Yes, out-of-hours work is a big part of what we do. That way a site in Blackfen doesn’t have to lose a day’s trading. Just ring 0345 646 2711 or send us an email with your opening times and we will plan around them.
Do insurers need proof of extract cleaning?
Many policies require TR19 cleaning, and insurers often ask to see the certificate. Without proof, a claim can be refused or reduced, so it’s worth checking your policy wording.
What if parts of the system can’t be reached?
We never leave them off the paperwork. You will know exactly which parts weren’t reached and why, and we can quote to improve the access.
What do you need from me for a quote?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. After that, simply call us on 0345 646 2711 or send us an email.
How much notice do you need?
The more notice, the better, especially for out-of-hours work. We usually quote within one working day, and there’s a 24/7 line for emergencies.
What paperwork comes with a kitchen extract clean?
A TR19 certificate, plus a full photo report. The report lists what was cleaned, anything we couldn’t reach and when the next clean is due.
What happens to the waste?
It’s contained and taken away. We collect grease, debris and waste water as we go, so it doesn’t spread.
Do you need kitchen extract cleaning in Blackfen?
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.
Any of these means the system needs a check-up:
- Poor airflow at the canopy
- Years of baked-on grease in the ducts
- A kitchen taken over without any extract records
- Grease smells coming from the extract
For schools such as Our Lady of the Rosary Catholic Primary School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.
What to look for in a quote
- What records you will receive afterwards
- Whether the whole system is included, or only the parts that are easy to reach
- How they set the interval to the next visit
- When they can work, and whether that’s outside your opening hours
How we price kitchen extract cleaning
Sites vary more than people expect. What affects the quote:
- Whether it’s a one-off visit or part of a schedule
- Site requirements such as sign-in and permits
- How big the system is
- Parking and loading at the site
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account, and the price is fixed before we start.
What we need to know
When you contact us, it’s useful to have:
- The roof, plant room or outside wall the system runs to
- Close-ups of filters, grilles, hatches or access panels
- The paperwork from the last visit, if you have it
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.
What kitchen extract cleaning looks like in Blackfen
According to Food Standards Agency records, there are about 41 pubs and bars within roughly a mile and a half of the centre of Blackfen. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Fire safety in Blackfen falls to London Fire Brigade. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Overnight is the normal time to clean a London kitchen extract, so trading is not affected.
If you run a café or takeaway near Falconwood station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits. A hall kitchen that only cooks for events, whether near Church of the Good Shepherd or elsewhere in Blackfen, still needs its extract cleaned, just less often.

How the visit works
Your trading hours come first. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes anything from a few hours to a full night, depending on the size of the system. Expect the work in Blackfen to happen after your last customer leaves, not during trading.
- We survey the system first, from your pictures and details or on a site visit.
- Set points are tested for grease thickness and the quote is fixed before we start.
- Once the kitchen has closed and the equipment has cooled, we sheet and protect the area.
- The whole route is cleaned, from the canopy through the ductwork to the fan and the discharge.
- Finally the system is re-tested and photographed, and the certificate and report follow.
Before we arrive
- Mention any parking or loading restrictions
- Clear the space around the work
- Allow time for equipment near the work to be turned off and cool down

Staff cleaning versus specialist work
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
