North Watford kitchens: local notes
There are about 158 restaurants, cafés and works canteens and about 50 takeaways and sandwich shops within about 1.5 miles of central North Watford, 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. Kitchens in North Watford get their food hygiene inspections from Watford council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Our report lists what was cleaned and when, which is useful to have ready. The fire and rescue service for North Watford is 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 look after a school kitchen, at a school such as Knutsford Primary Academy or anywhere near North Watford, the holidays are the usual time for a TR19® clean. If you run a café or takeaway near Watford North station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits.

TR19 inspection for kitchens and businesses in North Watford
A pre-clean survey looks at the whole system, from canopy to discharge. Access is checked along the full length, and record grease readings at set points. The work covers deposit thickness tests, access surveys and pre-clean surveys, and the jobs we see most are cleaning intervals that may not suit the kitchen and confirming a clean reached the whole system.
Kitchens around a place like North Watford are often in older buildings or single-storey extensions, with the duct running through a roof space or up an outside wall. Long horizontal runs like that hold grease and need access panels to reach.
The sign-off is always in writing: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

Your questions about TR19 inspection in North Watford
Do you work at weekends in North Watford?
Yes, nights and weekends are routine for us. The work in North Watford can fit around your hours. Your opening times are the first thing we ask for.
Which fire service covers North Watford?
Hertfordshire Fire and Rescue Service is the fire and rescue service for North Watford. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Can you set up regular visits?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. Each report recommends when the next visit should be.
Is North Watford in your area?
Yes. We work in North Watford and the rest of Hertfordshire, as part of our work across South East England and London. To book, give us a ring on 0345 646 2711, or email photos.
Is TR19 cleaning the law?
No, not in itself. The Fire Safety Order 2005 still requires the responsible person to manage fire risk, which in a kitchen includes grease in the extract. Many insurers also expect TR19 cleaning.
What happens to the waste?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. None of it is left on site.
What is post-clean verification?
A post-clean check records grease readings and pictures after the work, whoever did the clean.
How much notice do you need?
Book as early as you can for planned work, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
What happens on the day
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool first, and the area around the work is covered and protected. On site, it takes an hour or two for a single kitchen, longer for a large or complex system. Tell us about any gates, ladders or locked plant areas at your site near North Watford when you book.
- Post-clean verification is booked once the clean is done.
- We open the access points used on the clean.
- Grease readings are taken again at set points.
- Photos are taken to show the condition after the clean.
- We report the findings and flag any areas that need more work.
Before we arrive
- Find the previous report, if there is one
- Let us know about permits to work or site inductions
- Arrange a key holder or contact on site
How to get a quote
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.

How we price TR19 inspection
Every site gets its own quote. This is what makes a difference:
- The scale of the work
- The condition we find in the survey
- When the work can happen, such as evenings, overnight or weekends
- Access, including roofs, risers and ceiling voids
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are unsure, call us on 0345 646 2711, or email photos and we’ll give you an honest view and a fixed quote.
Asking for a quote
There’s no need for technical detail. It helps if you can send:
- Close-ups of filters, grilles, hatches or access panels
- When the site is open and when it’s quiet
- Where the site is and what kind of site it is
- How we’d reach plant on a roof or in a plant room
Getting a quote does not 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.
What a clean won’t put right
In fairness, there are a few things this work won’t fix:
- Parts of the duct nobody can reach yet
- The grease itself, which needs a full or spot clean
- Design faults in the extract system
Not sure which it is? You can phone us on 0345 646 2711, or email photos and we’ll tell you honestly.
What the work covers
- Deposit thickness tests
- Insurer audits
- Post-clean checks
- Access surveys
- Pre-clean surveys
- Wet film thickness tests
Why deal with it now?
Skipping grease testing leaves the cleaning interval to guesswork. Any reading of 500 microns or more needs immediate spot cleaning under TR19® Grease, and you can only act on that if you’ve measured it. You choose the date of a planned visit, and a breakdown never asks.
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.
What you get with us
- Full insurance on every job
- Evenings, overnight and weekends, plus 24/7 emergency callout
- One number for every site across the South East and London

Do you need TR19 inspection in North Watford?
Grease in a duct is flammable fuel. Flames from the range can be pulled into the canopy and travel through the ducts to other parts of the building. Knowing how much there is lets you act before it becomes a hazard.
The symptoms we are asked about most are:
- Checking the result of a recent clean
- Systems cleaned on a calendar with no measurements
- Extracts that may be over the 200 micron mean
- Kitchens taken over with no cleaning records
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to North Watford is Watford General Hospital, about 1.8 miles south.
What to look for in a quote
- Whether they recommend a next date
- What’s included in the scope, part by part
- What happens if part of the system cannot be accessed
- Whether the figure could change on the day
Different parts, different methods
Canopy and plenum
Behind the filters, the plenum catches plenty of grease. Readings and photos are taken in the plenum on every inspection.
Restaurants, pubs and hotels
BESA’s minimum for heavy use of 12 to 16 hours a day is a clean every 3 months, with testing showing whether more is needed.
What your team can do, and what needs us
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
