Kitchen extracts in Friern Barnet
The Food Standards Agency lists about 40 pubs and bars and about 3 hotels, B&Bs and guest houses as registered food businesses in and around Friern Barnet, up to about a mile and a half out. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. In London, kitchens are normally cleaned overnight, when the kitchen is closed and loading is easier. In Friern Barnet, food businesses are inspected by environmental health officers from Barnet council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A dated certificate in the maintenance file answers the question before it’s asked.
Healthcare kitchens, like those at hospitals such as Coppetts Wood Hospital (about 0.7 miles south), often cook for long hours, which puts them in BESA’s heavier-use bands. A hall kitchen that only cooks for events, whether near St John's Church or elsewhere in Friern Barnet, still needs its extract cleaned, just less often. A kitchen near New Southgate station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval.

Grease filter exchange for kitchens and businesses in Friern Barnet
The filters in the canopy are the first thing cooking vapour meets. They catch grease before it reaches the plenum and ductwork, but only while they’re reasonably clean. Our grease filter exchange service swaps dirty filters for clean ones on a schedule. The work covers school and hospital kitchens, wall canopies and baffle filters, and people most often call us about a canopy running with filters missing and grease left in baffles after washing.
Kitchens in Friern Barnet, like many across London, can share a building with flats or offices, with the duct running up through shared risers. A duct fire there can reach parts of the building far from the range, which is why keeping it clean to TR19® matters.
For insurers and inspectors, the record counts. So every job comes with a written report and pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What else we do in Friern Barnet
What your team can do, and what needs us
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
What affects the quote in Friern Barnet
Some jobs are bigger than they look, and some smaller. The main factors:
- Whether several sites go on one quote
- Site requirements such as sign-in and permits
- The condition of the system
- Whether we need access equipment or extra panels
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re unsure, ring 0345 646 2711 or email us and we will give you an honest view and a fixed quote.
What to send for a quote
Before you ask for a quote, gather:
- Photos showing the whole system and its surroundings
- Where the site is and what kind of site it is
- Any symptoms, from odd noises to smells or leaks
- Close-ups of filters, grilles, hatches or access panels
Getting a quote does not take long. Send a few details and pictures, and we typically reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
Part by part
The plenum
Heavy grease in the plenum often follows clogged or missing filters, or that a full clean is due.
Baffle filters
In a baffle filter, the air zigzags through metal baffles. Grease drops out as it does.
Looking after it afterwards
Think of this as the after-treatment advice, short and simple:
- Keep every filter in place during service
- Look out for drips from the canopy
- Do not let the full clean slip because filters are changed
- Make sure we can reach the canopy on exchange day
Keep an eye out for filters that have been taken out. A missing filter leaves a gap for grease, so let us know if one goes missing or gets damaged.
Bent or missing filters let grease straight past. Sorting them now keeps grease where it can be caught.
Multi-site and managed buildings
For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.
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.
Leave it or put it right?
Filters full of grease are fuel sitting right above the cooking. Flames from the range can be drawn up into the canopy, and from there into the duct. Clean filters mean less fuel in the canopy. For a site in Friern Barnet, fitting the work in overnight now is far easier than closing at short notice later.
Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at and we will price it together.

FAQs for Friern Barnet
Who would carry out a food hygiene inspection at a kitchen in Friern Barnet?
The local authority for Friern Barnet is Barnet council, and its environmental health team does the inspecting. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Can you come to Friern Barnet after we close?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Your opening times are the first thing we ask for.
Who is the responsible person?
It depends on the building. Under the Fire Safety Order 2005, it’s the responsible person, which can be the employer, the owner, a landlord, an FM or a managing agent.
How much does a filter exchange service cost?
Pricing depends on the kitchen, so we quote once we know your filters and schedule. We give you a fixed quote before the service starts.
What’s TR19?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not legislation, but it’s the standard people check against.
What do you do to protect the area?
By covering it before any work starts. The work is kept contained and leave the area clean.
What if parts of the system can’t be reached?
We record them on the report, with pictures where possible, and we tell you what would make it reachable, such as extra access panels in ductwork.
How much notice should we give?
Earlier is better, particularly for night and weekend visits. Quotes normally come back within one working day, and emergencies are covered by our 24/7 line.
What happens on the day
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. The visit itself takes anything from a few minutes to an hour or so, depending on the number of filters. Night and weekend working is normal for us in London, and a site in Friern Barnet is no exception.
- First, we record the size, type and number of filters in each canopy.
- Together we set how often the filters should be changed.
- At every visit, the greasy filters are lifted out.
- Clean filters go straight back in, seated properly with no gaps.
- Anything we notice, such as bent filters or a dirty plenum, is pointed out.
How to prepare
- Tell us about site rules, permits or sign-in
- Agree a time when the area can be out of use
- Move anything stored near the system
