TR19 inspection in Potters Bar
Post-clean verification is a check carried out once the cleaning is done, with fresh grease readings, photos and a look at the areas that were cleaned. It shows whether the system was left in the condition the paperwork describes. If you are dealing with heavy grease suspected in the plenum or ducts and pre-clean surveys before a first TR19 clean, we can help, from wet film thickness tests, deposit thickness tests and post-clean checks onwards.
Many kitchens in a town like Potters Bar were fitted into buildings built for something else, which can mean awkward duct routes, long flat runs and not enough access panels. Where the duct cannot be reached, new panels can be fitted, and anything left uncleaned is recorded on the report.
Our accreditations include CHAS, SafeContractor and 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.

How it works
Your staff do not need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Before we leave, the area is tidied and the paperwork follows. Before the visit, a few pictures of the system and how to reach it help us plan the work in Potters Bar.
- We go through any past certificates and reports.
- The layout is traced from the canopy to the discharge.
- We note where access panels are and where more are needed.
- Grease readings are taken and photos recorded.
- You get a report and a fixed quote for the clean.
Preparing for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Let us know when the site is closed or quiet
- Mention any locked doors, roof access or ceiling voids

Advice
Keeping the system healthy
So the system stays in good health:
- Mention new equipment or longer hours at the next test
- Keep TR19 certificates, readings and reports together
- Clean or swap grease filters as often as the kitchen needs
- Keep access panels clear and unpainted
Any access problems we found are listed with a suggested fix. With panels fitted, the next clean can cover every section.
Regular grease readings keep the cleaning interval honest. It spots changes in how fast grease builds.
What staff can safely do
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We’ll take a look and send you a fixed quote.

Why deal with it now?
A check after cleaning shows whether the work reached every part it should have, before the next clean is due. A small fault found now is a quick job; the same fault found later can close the site.
What you pay depends on the size of the system, what state it’s in and how easy it is to reach. You get a fixed price before work begins, so you know where you stand.

Signs you need TR19 inspection in Potters Bar
Insurers, fire officers and environmental health officers look to TR19® as the benchmark. TR19® itself is not law, but the Regulatory Reform (Fire Safety) Order 2005 requires the responsible person to assess and reduce fire risk, and in a kitchen that means keeping grease under control.
Keep an eye out for any of the following:
- Systems that need surveying before cleaning
- Sites with gaps in their extract records
- Extracts that have never been grease tested
- Uncertainty over how often to clean
Healthcare kitchens, like those at hospitals such as Barnet General Hospital (about 3.4 miles south-west), often cook for long hours, which puts them in BESA’s heavier-use bands.
Questions to ask before booking
- Whether the quote shows VAT
- Whether they recommend a next date
- Proof of insurance
- Whether a written report and photos are included
Your questions about TR19 inspection in Potters Bar
Which fire service covers Potters Bar?
Potters Bar is in the area of Hertfordshire Fire and Rescue Service. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Who inspects food businesses in Potters Bar?
Kitchens in Potters Bar are inspected by Hertsmere council’s environmental health officers. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
What does a pre-clean survey involve?
The survey covers the whole system, grease readings and access to each section. From it, we plan the clean and quote a fixed price.
Is there a survey before the work?
Yes, always. Diagnosis comes before treatment: the survey shows what needs doing and what access we need and the fixed quote is built on it.
What should I send you?
Where the site is, what it is and when it’s open, plus pictures of the system and your last certificate or report if you have one.
Which accreditations do you hold?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We’re fully insured and have been trading since 2009.
What do you do to protect the area?
We start with protection: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
Can you look after several sites?
Yes. You deal with one contact for every site across London and the South East, with visits on a regular schedule.
What TR19 inspection can’t fix
In fairness, there are a few things this work will not fix:
- Hidden runs that need access panels first
- A faulty or failing extract fan
- The responsible person’s own fire risk assessment
If you are not sure, just call 0345 646 2711 or email us and we will give you a straight answer before you book.

How the job changes from site to site
Canopy and plenum
Clean-looking filters don’t mean a clean plenum. So we measure behind the filters, not just in front.
Vertical risers
Risers carry the extract up through the building. Grease can run down and collect at the base, so the base is a key test point.
TR19 inspection around Potters Bar
There are about 41 restaurants, cafés and works canteens and about 23 sandwich bars and takeaways across Potters Bar and its immediate surroundings (about a mile and a half), according to the Food Standards Agency’s register. Where they cook under a canopy, a grease reading is the way to tell whether the extract is due a clean. The fire and rescue service for Potters Bar is Hertfordshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. Food hygiene inspections in Potters Bar are the job of Hertsmere council’s environmental health team. Extraction counts as kitchen equipment, so its condition can come up on the day. Our report lists what was cleaned and when, which is useful to have ready.
Where a hall near St. Mary's Church, or anywhere in Potters Bar, hosts lunch clubs or events, its extract gathers grease just as a café’s does. If you cook for passing trade around Potters Bar station, the extract can be cleaned between your last and first customer.
