TR19 inspection in East Finchley, done properly
A fixed schedule doesn’t always match how a kitchen really cooks. In a busy kitchen, grease can build faster than the minimum intervals allow for, which is why measurement matters. Our readings give your risk assessment real numbers to work from. The work covers deposit thickness tests, access surveys and post-clean checks, and people most often call us about checking the result of a recent clean and uncertainty over how often to clean.
London kitchens tend to trade late and open early, so work in East Finchley is normally booked for the night or the early hours. Before the clean, we agree loading, parking and roof access with whoever manages the building.
A written report with pictures follows each visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Part by part
Canopy and plenum
Clean-looking filters don’t mean a clean plenum. That’s why we test behind them.
Horizontal duct runs
Grease settles on the floor of horizontal ducts as the air cools. We test at points along the run through access panels.
Fixed quotes for TR19 inspection in East Finchley
We quote each job individually. This is what makes a difference:
- How easy every part is to reach
- Working hours and out-of-hours timing
- Whether it’s a one-off visit or part of a schedule
- Travel, parking and unloading
What you pay depends on the size of the system, what state it’s in and how easy it is to reach. We give you a fixed price before work begins, so you know where you stand.
What to send for a quote
Before you ask for a quote, gather:
- The roof, plant room or outside wall the system runs to
- The site address and the type of premises
- Wide photos of the system and the area around it
- Your opening hours and when the area is out of use

What we are called out for in East Finchley
Looking at a canopy tells you little about what’s in the duct. A system can look clean at the filters and be heavily coated further in, so readings are the reliable guide.
Any of these means the system needs a check-up:
- Uncertainty over how often to clean
- Heavy grease suspected in the plenum or ducts
- An insurer’s request for a TR19 audit
- Kitchen extract systems with no recent grease readings
Heath Hall, about 1.1 miles south, is one of the historic houses near East Finchley; if you run event catering at a venue like that, cleans can be booked between functions.
What your quote should include
- Whether the quote is based on a survey or photos
- Which accreditations they hold, and whether you can check them
- When they can work, and whether that is outside your opening hours
- Whether they’re fully insured
Your questions about TR19 inspection in East Finchley
Do you clean school canteen extracts around East Finchley out of term?
Yes, and it’s the easiest time to do it. Around East Finchley, the Food Standards Agency lists about 46 schools and colleges with registered kitchens within a mile and a half or so. Send us your term dates when you ring 0345 646 2711, or email photos, and we will fit the work in.
Can the work in East Finchley be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in East Finchley needn’t be disturbed. Your opening times are the first thing we ask for.
What is post-clean verification?
We visit after a clean, take readings at set points and photograph the system. Any areas that weren’t cleaned properly are flagged.
Can we book visits on a schedule?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. Each report recommends when the next visit should be.
How long does grease testing take?
It takes a morning or less for one kitchen, more where there are several systems. We fit it around when the kitchen is closed or quiet.
Can one contract cover all our sites?
Yes. Our area covers London and the South East, so we can schedule a run of sites as one programme. Each site gets its own report and pictures.
Is TR19 a legal requirement?
No, TR19® is not legislation. But the responsible person must assess and reduce fire risk under the Fire Safety Order 2005, which in a kitchen includes grease in the extract. Many insurance policies also require TR19 adherence.
How far ahead should we book?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
Keeping the system healthy
To keep the system working properly between visits:
- Clean or swap grease filters as often as the kitchen needs
- Tell us if menus or opening hours change
- Have the latest report ready for insurance renewals
- Diary the next grease test and clean
If any reading is 500 microns or more, the report flags it for immediate spot cleaning, and we can arrange it.
When cooking hours or the menu change, check the interval still fits. A quick grease test answers the question.
Kitchen extracts in East Finchley
According to Food Standards Agency records, there are about 37 pubs and bars and about 6 hotels and guest houses in and around East Finchley, up to about a mile and a half out. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. London jobs normally start after the last service, with loading and roof access agreed with the building first. The fire and rescue service for East Finchley is London Fire Brigade. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
Volunteers running a hall kitchen near Church of the Holy Trinity, or anywhere in East Finchley, may not know when the extract was last cleaned, and a grease test settles it. Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to East Finchley is Finchley Memorial Hospital, about 1.1 miles north.

Why it’s worth doing now in East Finchley
Post-clean verification shows whether the system was left the way the certificate says, while there’s still time to put anything right. A booked night’s work in East Finchley costs you no trading time; an unplanned closure does.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you’re unsure, ring 0345 646 2711 or use the quote form and we’ll give you an honest view and a fixed quote.
