Common questions in High Barnet
How do you handle parking and loading in High Barnet?
London parking can be tight, so details of loading bays and permits help. If the building has a loading slot system, we will book into it.
Who enforces fire safety at workplaces in High Barnet?
That’s London Fire Brigade. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
At what point does grease need cleaning?
Two figures matter: a mean of no more than 200 microns between cleans, and 500 microns at any single point, which needs immediate spot cleaning. Our report sets your readings against both.
When should we have our next grease test?
We suggest a next test date in every report, taking the readings and the kitchen’s hours into account. A risk assessment based on measured grease should set the interval.
How do you measure grease in a kitchen extract?
It’s a measurement of how much grease is coating the inside of the extract, using the Wet Film Thickness Test (WFTT) or Deposit Thickness Test (DTT). The results are given in microns.
Can the work be done while we’re closed?
Yes, and that is how we prefer to work. We book the visit for when the area is out of use, whether that’s late evening, overnight or a weekend.
What happens on a pre-clean survey?
We survey, measure and photograph the system first. We can work from photos and details, or visit, whichever suits the system.
What do you do to protect the area?
Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
How we handle TR19 inspection in High Barnet
BESA sets minimum cleaning intervals by daily use: heavy use (12 to 16 hours a day) every 3 months, moderate use (6 to 12 hours) every 6 months and light use (2 to 6 hours) every 12 months. Grease testing shows whether your kitchen needs cleaning more often than that. If you are dealing with heavy grease suspected in the plenum or ducts and kitchens taken over with no cleaning records, we can help, from insurer audits, post-clean checks and pre-clean surveys onwards.
In London, few kitchens can spare a day to close, so extract cleaning in High Barnet is typically done overnight, after the last service. Parking, loading and access to the roof are agreed with the building before the night of the clean.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

What TR19 inspection looks like in High Barnet
Food Standards Agency data counts about 52 restaurants, cafés and canteens and about 24 takeaways across High Barnet and its immediate surroundings (about a mile and a half). A WFTT or DTT reading tells each of those kitchens whether its grease is staying under the 200-micron mean. It’s Barnet council that sends environmental health officers to food businesses in High Barnet. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Before-and-after pictures from each clean are a simple way to show the extract is in hand. London jobs usually start after the last service, with loading and roof access agreed with the building first.
Bursars and site managers at schools such as Foulds School tend to book extract cleaning for when the kitchen is empty. If you run catering at a historic house or estate in the area (Wyllyotts Manor is about 2.9 miles north), event kitchens in older buildings often have awkward duct runs that need planning.
High Barnet is about 1 mile north-west of Barnet, in Greater London. Across the EN5 area, we cover TR19 inspection for commercial sites.

In-house cleaning or a specialist?
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We’ll take a look and send you a fixed quote.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.

Managing agents and facilities teams in High Barnet
Facilities teams in offices, schools and healthcare sites book us too in High Barnet and across Greater London. Larger estates can be phased building by building around the people who use them.
We regularly work with managing agents. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.
Honest limits
We won’t sell you work that doesn’t address the problem, so here are the limits:
- The responsible person’s own fire risk assessment
- Sections with no access, until panels are fitted
- Heavy deposits found on test, which still need cleaning
Not sure which it is? You can call us on 0345 646 2711 or drop us a line and we will tell you honestly.
Parts of the system we cover
- Post-clean checks
- Access surveys
- Deposit thickness tests
- Wet film thickness tests
- Pre-clean surveys
- Insurer audits
Aftercare tips
So the system stays in good health:
- Keep access panels clear and unpainted
- Wipe the canopy surfaces regularly
- Store grease readings where your insurer can see them
- Share inspection reports with your insurer or broker when asked
Readings of 500 microns or more are highlighted as needing immediate spot cleaning, and we can arrange it.
Fit access panels where the survey finds sections can’t be reached, so every part of the duct can be cleaned.

Related advice
What we are called out for in High Barnet
Insurers, fire officers and environmental health officers look to TR19® as the benchmark. It is not legislation; the legal duty comes from the Fire Safety Order 2005, under which the responsible person must reduce fire risk, and in a kitchen that means keeping grease under control.
Common reasons sites call us are:
- Sections of duct that can’t be reached
- Surveys needed before quoting a full clean
- Kitchen extract systems with no recent grease readings
- Missing TR19 certificates or history
Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to High Barnet is Barnet General Hospital, about 0.5 miles south-west.
