Grease, kitchens and Hook
According to Food Standards Agency records, there are about 11 bars, pubs and nightclubs and about 3 hotels and guest houses within about 1.5 miles of central Hook. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Hook sits within the area of London Fire Brigade. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. Overnight is the normal time to clean a London kitchen extract, so trading isn’t affected.
Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Hook is Tolworth Hospital, about 1.1 miles north-east. If you run a café or takeaway near Chessington North station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits.
Hook is about 2 miles north-west of Ewell, in Greater London. Whatever kind of site you run in Hook, TR19 inspection is something we can help with.

About our TR19 inspection in Hook
BESA’s minimum cleaning frequencies depend on how long the kitchen cooks each day: every 3 months for heavy use of 12 to 16 hours a day, every 6 months for moderate use of 6 to 12 hours, and every 12 months for light use of 2 to 6 hours. Those are minimums, and grease readings help set the real interval. The work covers wet film thickness tests, access surveys and deposit thickness tests, and the jobs we see most are heavy grease suspected in the plenum or ducts and cleaning intervals that may not suit the kitchen.
London kitchens tend to trade late and open early, so extract cleaning in Hook is usually done overnight, after the last service. Before the clean, we agree loading, parking and roof access with whoever manages the building.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What else we do in Hook
Do you need TR19 inspection in Hook?
You can’t judge grease thickness by eye. Clean filters can hide a heavy layer behind them, which is why readings matter.
If you notice any of these, it’s worth a diagnosis:
- Checking the result of a recent clean
- Cleaning intervals that may not suit the kitchen
- Pre-clean surveys before a first TR19 clean
- Insurers asking for TR19 evidence
Volunteers running a hall kitchen near St Paul's, or anywhere in Hook, may not know when the extract was last cleaned, and a grease test settles it.

What staff can safely do
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We will take a look and give you a fixed quote.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
How the visit works
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool first, and floors and nearby surfaces are sheeted. On site, it takes a morning or less for one kitchen, more where there are several systems. Most London sites cannot stop for the day, so work in Hook is normally done overnight, early in the morning or at weekends.
- First we book a time that won’t disrupt cooking.
- Every part of the system is examined, end to end.
- We take WFTT or DTT readings at set points along the system.
- Photos are taken at each point, and access gaps noted.
- You get a report with readings, pictures and recommendations.
Getting ready for the visit
- Tell us about site rules, permits or sign-in
- Let us know when the site is closed or quiet
- Plan for cooking equipment or plant to be off before we arrive
How to get a quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.
Advice
Different parts, different methods
Vertical risers
In buildings with several floors, the riser may pass through other tenants’ space, so we arrange access ahead of time.
Restaurants, pubs and hotels
We test between services, early in the morning or after close so the kitchen keeps cooking.
Looking after it afterwards
Here’s the after-treatment advice, in brief:
- Have the latest report ready for insurance renewals
- Keep grease filters clean and fitted properly
- Clean grease off the canopy between professional cleans
- 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 quote to do it.
Regular grease readings keep the cleaning interval honest. It shows if build-up is speeding up.
Your questions about TR19 inspection in Hook
Can the work in Hook be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. It means the site in Hook keeps running as normal. Let us know the hours you are closed and we’ll book within them.
Can a school canteen extract in Hook be done out of term time?
Yes, and it’s the easiest time to do it. There are about 19 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Hook. Tell us your holiday dates and we will book the visit for when the site is empty.
How long does grease testing take?
Typically, the inspection takes a morning or less for one kitchen, more where there are several systems. System size and access decide the rest.
How do you measure grease in a kitchen extract?
It’s a measurement of how much grease is coating the inside of the extract, by WFTT or DTT. The results are given in microns.
How do you keep the site clean during the work?
We cover floors and nearby surfaces with sheeting before work begins, and waste is contained as we go. At the end, the area is cleaned down.
Do you carry out TR19 audits for insurers?
Yes. We inspect the system and produce a report with grease readings, photos and any inaccessible areas. You can pass it straight to your insurer or broker.
How much does TR19 inspection cost?
Every site is different, so each gets its own fixed quote. To get one, ring 0345 646 2711 or email us and tell us about the site and its opening hours.
Do you offer maintenance contracts?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. The report from each visit recommends the next date.
Fixed quotes for TR19 inspection in Hook
We quote each job individually. This is what makes a difference:
- How many systems or sites are involved
- The size of the system
- The times the site is available
- Site rules, permits and inductions
We don’t list prices on the website, because the cost depends on the site in front of us. For a fixed quote, call us on 0345 646 2711 or drop us a line, and we will talk you through it.
What to send for a quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Detail shots of panels, filters and grilles
- Any symptoms, from odd noises to smells or leaks
- How we’d reach plant on a roof or in a plant room
- Wide photos of the system and the area around it
Every quote begins with a look at the system, from your pictures and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work, before work begins.
Why deal with it now?
Sites in Hook that have never measured grease cannot tell whether their cleaning interval suits the kitchen. Testing gives you the evidence to set it properly. London buildings are shared, so a fire or failure in one system can reach the neighbours above and beside you.
What you pay reflects the actual work. That’s why every job is surveyed first, and why the quote is fixed before any work starts.

- Photo reports with every job
- We diagnose before we treat
- One contact for all your sites in London and the South East
