Greater London · Kitchen extract cleaning
Kitchen extract cleaning in Mill Hill, Greater London
Our technicians work in Mill Hill on kitchen extract cleaning. Out-of-hours visits, a fixed quote and a written report with pictures as standard.
- A kitchen taken over without any extract records
- A system with no record of a TR19 clean
- Cleaning needed before an insurance renewal or survey
What the work involves, part by part
Ductwork and risers
Vertical risers carry the air up through the building, and grease often collects at the bottom of them. Access panels along the riser let us clean it in sections.
Schools, hospitals and care homes
Some healthcare kitchens never fully close. We plan the clean around meal times and work in a contained, tidy way with as little disruption as possible.
How we handle kitchen extract cleaning in Mill Hill
Insurers often want evidence of regular TR19 cleaning, and some may refuse or reduce a claim when it’s missing. The certificate and photo report from each clean in Mill Hill give you that record, ready for the fire risk assessment file. We are often asked to deal with a smoky, hot kitchen with weak extraction and proof of cleaning requested by an insurer, on canopies and hoods, discharge points and vertical risers. Searching for commercial kitchen extraction cleaning in Mill Hill? Duct Doctor has covered London and the South East since 2009, with a certificate and photo report after every clean.
The fire risk in a kitchen extract sits in the parts nobody sees: the plenum, the duct and the fan, so that is where most of the work in Mill Hill goes.
London kitchens tend to trade late and open early, so work in Mill Hill is normally booked for the night or the early hours. Parking, loading and access to the roof are agreed with the building before the night of the clean.
The paperwork matters as much as the work. Each visit is written up with pictures, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

What else we do in Mill Hill
Kitchen extract cleaning around Mill Hill
Look up Mill Hill on the FSA’s food hygiene register and you’ll find about 46 cafés, restaurants and staff canteens and about 21 takeaways in and around Mill Hill, up to about a mile and a half out. Those that fry, grill or roast under a canopy need their extracts cleaned at intervals set by how long they cook. Kitchens in Mill Hill get their food hygiene inspections from Barnet council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Most London extract cleaning happens at night, after the last service.
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Heath Hall is about 4 miles south-east), access may need planning. Healthcare kitchens, like those at hospitals such as Edgware Community Hospital (about 2 miles south-west), often cook for long hours, which puts them in BESA’s heavier-use bands.
Mill Hill is about 1 mile north-east of Burnt Oak, in Greater London. Sites in Mill Hill get the same service as everywhere we cover: a survey first, a fixed quote, work timed around your hours and a report with photos. Our Greater London coverage runs to 764 places, Mill Hill among them. You can also see our page for London, about 10 miles away.

For landlords and multi-site operators
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
Keeping records across a portfolio is half the battle. Every visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.
Why act early in Mill Hill
If there’s a fire and the extract hasn’t been cleaned, the paperwork becomes the problem. Many policies require cleaning to TR19, and an insurer can refuse or reduce a claim without proof. A current certificate is far easier to produce than an explanation. It’s better booked as a planned job in Mill Hill than handled as an emergency.
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote, and the price is fixed before work begins.

Do you need kitchen extract cleaning in Mill Hill?
The type of cooking changes the amount of grease. Fryers, grills and open flames throw much more fat into the extract than gentler cooking, so two kitchens with the same hours can need very different intervals.
Look out for these warning signs:
- An extract that has never been cleaned to TR19
- An inspection that picked up a dirty extract
- A new tenancy or takeover with no cleaning history
- Poor airflow at the canopy
If you look after a school kitchen, at a school such as St Paul's CofE Primary School NW7 or anywhere near Mill Hill, the holidays are the usual time for a TR19® clean.
Questions to ask before booking
- Whether they recommend a next date
- What insurance they carry
- Whether the quote shows VAT
- What hours they’ll be on site
What happens on the day
We are used to working while the site is closed. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. On site, the work takes anything from a few hours to a full night, depending on the size of the system. If your building in Mill Hill has sign-in rules, permits or key holders, mention them when you book.
- Diagnosis comes first, with a survey of the system and how it’s reached.
- We record grease levels at set points, then fix the price.
- After the kitchen closes, we sheet the area and set up to contain grease and water.
- Heavy deposits are scraped by hand and the system degreased to TR19® Grease.
- The sign-off: post-clean readings, a TR19 certificate and a photo report with the next clean date.
Preparing for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Dig out any earlier paperwork for the system
Getting a quote
Every quote begins with a look at the system, either from photos and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before we start.
Advice
When it’s something else
Kitchen extract cleaning cannot fix everything, and we’d rather say so up front. It does not solve:
- A duct that’s holed or coming apart
- An undersized canopy or fan
- Blocked drains from a neglected grease trap (a separate service)
If you’re not sure, just give us a ring on 0345 646 2711 or use the quote form and we will give you a straight answer.
What the work covers
- Discharge points
- Extract fans
- Canopies and hoods
- Vertical risers
- Plenums and filters
- Horizontal duct runs
Looking after it afterwards
Aftercare is simple, and it makes the next visit easier:
- Keep the extract on whenever the range is lit
- Refit filters properly after cleaning
- Report grease drips, smells or fan noise right away
- Diarise the next clean as soon as you get the certificate
The kitchen is left clean and ready for the next service. Grease and dirty water are collected and taken off site, so you can start cooking as normal.
Run the extract whenever the kitchen is cooking. Cooking with the extract off lets grease and heat settle in the canopy, and the next clean has more to do.
Mill Hill questions
Is parking a problem for work in Mill Hill?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Night visits tend to make loading easier on London streets.
Can you clean school kitchen extracts in Mill Hill during the holidays?
Yes, holiday work suits schools best. There are about 29 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Mill Hill. Tell us your holiday dates and we will book the visit for when the site is empty.
How do you protect the area?
We start with protection: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
What does kitchen extract cleaning cost?
Size, condition, access and working hours all affect the cost. Ask us for a fixed quote, typically ready within one working day.
Will my insurer ask for a TR19 certificate?
Grease-filled ducts can carry fire well beyond the kitchen. Many insurers require TR19 cleaning, and may refuse or reduce a claim without proof, so keep every certificate.
Do you offer emergency callouts?
Yes. There’s a 24/7 emergency line, for problems that cannot wait. Ring any time and tell us what’s happened.
Is TR19 a legal requirement?
TR19 isn’t written into law, but the responsible person still has a legal duty under the Fire Safety Order 2005. Insurers, fire officers and EHOs look to TR19 as the standard, and many policies require it.
Is there a survey before the work?
Yes, always. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it, and the quote is based on that.
