TR19 inspection for kitchens and businesses in Oxhey
A pre-clean survey is the diagnosis, and the clean is the treatment. We look at the system, take grease readings and photograph what we find, so the clean can be planned properly. The work covers deposit thickness tests, pre-clean surveys and post-clean checks, and people most often call us about sections of duct that can’t be reached and ductwork where grease may be over the TR19 limits.
Kitchens around a place like Oxhey are often in older buildings or single-storey extensions, where the duct may cross a roof void or climb an outside wall. Flat runs collect grease and need proper access to clean.
For insurers and inspectors, the record counts. 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.

Oxhey: your questions answered
Do you work overnight in Oxhey?
Yes, we can come after you close and finish before you open. It means the site in Oxhey keeps running as normal. When you ring 0345 646 2711 or send us an email, mention when the site is quiet.
Which council inspects kitchens in Oxhey?
Food hygiene inspections in Oxhey are carried out by Hertsmere council. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Do you have a 24/7 line?
Yes. Our emergency line runs 24/7, for problems that can’t wait. Ring any time and tell us what’s happened.
At what point does grease need cleaning?
Under TR19® Grease, the mean thickness should not exceed 200 microns between cleans. Any reading of 500 microns or more needs immediate spot cleaning.
Can you inspect our extract for our insurance company?
Yes. Insurers often want evidence the extract is managed to TR19®, and an audit report gives you that, with recommendations where something needs doing.
What does TR19 inspection cost?
We don’t publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. You get a fixed price before we start.
Can you set up regular visits?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
Where does the waste go?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. We don’t leave it behind.
Why deal with it now?
After an incident, an insurer can ask to see proof of TR19 cleaning and inspection. Without them, a claim can be reduced or refused. An up-to-date inspection report is a good place to start. When a site near Oxhey shuts unexpectedly, the people who rely on it notice at once.
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll go through it with you.

Staff cleaning versus specialist work
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
What affects the quote in Oxhey
The diagnosis comes before the price. We look at:
- What state the system is in
- One-off work versus a regular cycle
- Where the site is and how we reach it
- The size of the system
What you pay reflects the actual work. That is why every job is surveyed first, and the price is agreed before any work starts.
What to send for a quote
When you contact us, it’s useful to have:
- Your opening hours and when the area is out of use
- Any symptoms, from odd noises to smells or leaks
- A few general shots of the system
- Where the plant sits or the system leaves the building, such as a roof or outside wall
Getting a quote doesn’t take long. Call or email with a few details and you’ll typically have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
Between visits
Looking after the system between visits is straightforward, and it helps at the next visit:
- Keep the route to access panels clear
- Tell us if menus or opening hours change
- Have the latest report ready for insurance renewals
- Look out for grease drips round the canopy edge
Any access problems we found are listed with a suggested fix. Fitting them before the next clean means the whole system gets done.
Keep certificates, reports and readings in one place so the history is easy to show.
What we do, step by step
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. All told, the work takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. In a place like Oxhey, we fit the visit around your hours.
- After the clean, we arrange a time to check the system.
- The same access points are opened up.
- Grease readings are taken again at set points.
- Photos are taken to show the condition after the clean.
- The results are reported, with anything missed flagged.
Preparing for the visit
- Name a contact who can let us in at the agreed time
- Dig out any earlier paperwork for the system
- Make sure equipment near the work can be switched off and left to cool
How to get a quote

TR19 inspection in Oxhey: the local picture
The FSA’s food hygiene register includes about 25 pubs, bars and clubs within about 1.5 miles of central Oxhey. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Kitchens in Oxhey get their food hygiene inspections from Hertsmere council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Oxhey is covered by Hertfordshire Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
Term dates shape school work: for a school like Bushey Manor Junior School, an extract clean fits neatly into a half-term or summer break. If you run catering at a healthcare site, such as a hospital like Watford General Hospital about 1.2 miles west, the extract may need cleaning more often than a part-time kitchen.

Do you need TR19 inspection in Oxhey?
Not every section of a kitchen extract is easy to get to, so those sections can be skipped time and again. An inspection of a system in Oxhey shows where access panels are missing, so the gaps can be closed.
Signs it’s time to call us include:
- Insurers asking for TR19 evidence
- Missing TR19 certificates or history
- Confirming a clean reached the whole system
- Ductwork where grease may be over the TR19 limits
Church and community hall kitchens, near Church of St James or anywhere around Oxhey, are easy to forget, but their extracts collect grease like any other.

Restaurants, pubs and hotels
We test between services, early in the morning or after close so the kitchen keeps cooking.
