How kitchen extract cleaning works in N11
Few kitchens can stop cooking for a day so the extract can be cleaned. We work evenings, overnight and at weekends, or during holidays where a site closes for them. Equipment is switched off and left to cool, the area is sheeted, and the kitchen is handed back ready to cook. Typical jobs include proof of cleaning requested by an insurer and a new tenancy or takeover with no cleaning history, on discharge points, plenums and filters and canopies and hoods.
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. On site, the work takes as long as the system needs, from a few hours to several planned visits.
- 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.
- On the day, cooking equipment is switched off and left to cool, and everything nearby 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.
How we quote
The cost depends on how big the system is, what state it’s in and how easy it is to reach. We give you a fixed price before we start, so you know where you stand.

Getting a quote
The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

Kitchen extract cleaning around N11
Across N11, from Barnet, Palmers Green and Whetstone outwards, kitchens range from town-centre restaurants and takeaways to pubs, hotels, schools and care homes. Every one gets the same full TR19® clean, from the canopy to the discharge.
London and the South East cover everything from city basements to rural kitchens. Wherever the site is in N11, the work is done to the same TR19® standard.
Friern Barnet: Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Friern Barnet is Coppetts Wood Hospital, about 0.7 miles south. Church and community hall kitchens, near St John's Church or anywhere around Friern Barnet, are easy to forget, but their extracts collect grease like any other.
Keeping the system healthy
After the visit, a few habits help the work last:
- Do not let the canopy gutters overflow
- Keep the cleaning records where you can find them
- Keep to the recommended cleaning interval
- Tell us when the extract starts to drip or smell
When the clean is finished, grease readings are taken again at the same points, giving you before and after readings alongside the pictures. A TR19 certificate follows, issued through the BESCA Vent Hygiene Elite portal.
Report drips, smells or a noisy fan early. Drips, odours and fan noise often mean grease is building, and a grease thickness test can confirm it.
How we price kitchen extract cleaning
A fixed price needs a few facts first. We check:
- How many systems or sites are involved
- Working hours and out-of-hours timing
- Travel, parking and unloading
- Site requirements such as sign-in and permits
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will explain each part.
What we need to know
To speed up the quote, please include:
- The roof, plant room or outside wall the system runs to
- Where the site is and what kind of site it is
- The paperwork from the last visit, if you have it
- Photos showing the whole system and its surroundings
Need a price for kitchen extract cleaning? Please ring 0345 646 2711 or email us with a few details about the site. We will explain what we’d do and send a fixed quote before anything is booked.
What kitchen extract cleaning can’t fix
We will not sell you work that doesn’t address the problem, so here are the limits:
- A duct that is holed or coming apart
- Extraction that can’t cope with the cooking because of its design
- Fat blocking the kitchen drains
For landlords and multi-site operators
Multi-site operators often want one contractor and one number. 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 can quote for the whole system.
Part by part
Extract fan and discharge
The discharge is where air leaves the building, which can collect grease and stain the surface around it. We clean it where it can be safely reached, and any limits are recorded.
Canopy and plenum
Whether it’s one hood or a long island canopy, every section is cleaned and recorded in the photo report before and after.
Your questions about kitchen extract cleaning in N11
Why do insurers care about extract cleaning?
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’s the right cleaning interval for a kitchen extract?
The minimum is set by BESA guidance on daily use, from 3-monthly to 12-monthly. Heavy frying and grilling can mean shorter intervals, and readings will tell you.
Which sectors do you work in?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
Are you accredited for kitchen extract cleaning?
We clean to BESA TR19® Grease as a BESCA Vent Hygiene Elite member, and certificates go through the BESCA Vent Hygiene Elite portal. Duct Doctor has been trading since 2009.
What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Do you work with multi-site operators?
Yes. One number covers all your sites in our area, and visits can be set on a regular cycle.
Can you price the work without visiting?
Yes, if we can see what we need. If not, a site survey comes first, and the quote follows that.
