TR19 inspection in Bell Bar
Insurance policies often require evidence of TR19® cleaning and inspection. Without it, a claim can be refused or reduced. A TR19 audit sets out the system’s condition, with readings and photos, for sites in Bell Bar and the rest of Hertfordshire. Typical jobs include confirming a clean reached the whole system and heavy grease suspected in the plenum or ducts, across pre-clean surveys, wet film thickness tests and insurer audits.
For a kitchen in or near Bell Bar, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
Nothing is signed off by word of mouth: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Multi-site and managed buildings
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
If you look after several sites, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.
Why it’s worth doing now in Bell Bar
Skipping grease testing leaves the cleaning interval to guesswork. If grease reaches 500 microns anywhere, TR19® Grease calls for immediate spot cleaning, and you can only act on that if you’ve measured it. A fault that closes a site in a village like Bell Bar affects everyone who depends on it.
Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.

Honest limits
TR19 inspection can’t fix everything, and we will tell you before any work starts. It won’t put right:
- Fire safety duties beyond the extract system
- Design faults in the extract system
- Sections with no access, until panels are fitted
If you’re not sure, just ring 0345 646 2711 or send us an email and we’ll give you a straight answer before you book.

Different parts, different methods
Vertical risers
Vertical risers take the extract up through the floors. Grease can drain down and pool at the bottom, so the base is a key test point.
Restaurants, pubs and hotels
We test between services, early in the morning or after close so trading is not affected.
What we do, step by step
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes an hour or two for a single kitchen, longer for a large or complex system. The timing of a visit to Bell Bar is set by you, and the travel is our side of the planning.
- The visit is arranged for when the kitchen is not busy.
- Every part of the system is examined, end to end.
- Grease readings are taken at set points using WFTT or DTT.
- Photos are taken at each point, and access gaps noted.
- The findings go into a report with readings, photos and a recommended next clean.
Getting ready for the visit
- Dig out any earlier paperwork for the system
- Agree a time when the area can be out of use
- Plan for cooking equipment or plant to be off before we arrive

Advice
Bell Bar questions
Which fire authority looks after Bell Bar?
It’s Hertfordshire Fire and Rescue Service, which covers Bell Bar. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Can you work in Bell Bar outside opening hours?
Yes, evening, overnight and weekend work is normal for us. It means the site in Bell Bar keeps running as normal. Just call 0345 646 2711 or use the quote form with your opening times and we’ll plan around them.
Can you come out in an emergency?
Yes. Our emergency line runs 24/7 for anything that cannot wait until a planned visit. Call us any time and explain what’s happened.
How far ahead should we book?
The more notice, the better, particularly for night and weekend visits. Quotes typically come back within one working day, and there’s a 24/7 line for emergencies.
How much time does an inspection need?
Typically, the inspection takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. The size of the system and the access make the difference.
Can you verify a clean after it’s been done?
Verification means repeat readings and pictures once the clean is done. The report flags anything missed.
What do the grease readings need to be?
Between cleans, the mean should stay at 200 microns or below, and anywhere at 500 microns or more needs spot cleaning straight away.
What do you need from me for a quote?
The site address, the type of premises and your opening hours, plus pictures of the system and your last certificate or report if you have one.

What else we do in Bell Bar
Between visits
Think of this as the after-treatment advice, in brief:
- Look out for grease drips round the canopy edge
- Send TR19 audit reports to your insurer on request
- File every inspection report with your certificates
- Never cook with filters missing
You get a report with the grease readings, where they were taken and photos of each point. File it alongside your TR19 certificates.
Fit access panels where the survey finds sections cannot be reached, so grease is not left building in hidden parts.
TR19 inspection in Bell Bar: the local picture
The FSA’s food hygiene register shows about 10 restaurants, cafés and canteens within about 1.5 miles of central Bell Bar. For any of them with a canopy, measuring grease is better than guessing when to clean. Food hygiene inspections in Bell Bar are the job of Welwyn Hatfield council’s environmental health team. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Fire safety in Bell Bar falls to Hertfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
If you run catering at a healthcare site, such as a hospital like Queen Elizabeth II Hospital about 3.6 miles north, the extract may need cleaning more often than a part-time kitchen. If you run a church or community hall kitchen, near United Reformed Church Brookmans Park or elsewhere in Bell Bar, its extract still collects grease from every lunch and event. School kitchens, at schools like Chancellor's School for example, are usually cleaned in the holidays so no lunches are lost.

What affects the cost of TR19 inspection
The diagnosis comes before the price. The main factors are:
- What state the system is in
- The times the site is available
- A single visit or a regular plan
- Travel, parking and unloading
What you pay depends on the size of the system, the condition it’s in and access to every part of it. You get a fixed price before work begins, so you know where you stand.
Asking for a quote
Photos let us diagnose from a distance. The most useful are:
- The site address and the type of premises
