TR19 inspection in Westwick Row
A grease test measures how thick the grease is inside a kitchen extract system. We use the Wet Film Thickness Test (WFTT) or the Deposit Thickness Test (DTT), taking readings at set points. The results show whether the system needs cleaning and how soon. Common call-outs are for missing access panels found on survey and kitchens taken over with no cleaning records, across insurer audits, access surveys and post-clean checks.
Somewhere as small as Westwick Row, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Every one of them still needs its extract kept clear of grease, whatever the size of the place.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

Fixed quotes for TR19 inspection in Westwick Row
The diagnosis comes before the price. The main factors are:
- Site rules, permits and inductions
- Parking and loading at the site
- Working hours and out-of-hours timing
- How many systems or sites are involved
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered and we will price it together.
Asking for a quote
You do not need the technical terms. Just send:
- Problems your staff have spotted
- Any previous report or certificate
- Close-ups of filters, grilles, hatches or access panels
- A few general shots of the system
Every quote begins with a look at the system, either from photos and details you send or from a site visit. After that, you get a fixed price for the work, before we start.

The process
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’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes a morning or less for one kitchen, more where there are several systems. Somewhere as small as Westwick Row, the date and timings are agreed with you well before the day.
- First we look at the system’s cleaning history, if there is one.
- We follow the extract from canopy to discharge.
- Access panels are located and any missing ones noted.
- We measure the grease and photograph each point.
- You get a report and a fixed quote for the clean.
Before we arrive
- Let us know when the site is closed or quiet
- Find the previous report, if there is one
- Tell us about site rules, permits or sign-in
Ask for a quote
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

Common problems we fix in Westwick Row
You can’t judge grease thickness by eye. Clean filters can hide a heavy layer behind them, so readings are the reliable guide.
Any of these means the system needs a check-up:
- Extracts that have never been grease tested
- An insurer’s request for a TR19 audit
- Heavy grease suspected in the plenum or ducts
- Missing TR19 certificates or history
A hospital like Hemel Hempstead Hospital, about 2.1 miles west, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

Common questions in Westwick Row
Can the work in Westwick Row be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. That way a site in Westwick Row does not have to lose a day’s trading. Let us know the hours you are closed and we’ll book within them.
Which fire and rescue service is responsible for Westwick Row?
Hertfordshire Fire and Rescue Service is the fire and rescue service for Westwick Row. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
How much does TR19 inspection cost in Westwick Row?
Size, condition, access and working hours all affect the cost. Ask us for a fixed quote, normally ready within one working day.
Which accreditations do you hold?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We are fully insured and have been trading since 2009.
When should we have our next grease test?
Enough to be sure grease stays within the TR19® Grease figures between cleans. If readings rise, the interval should shorten.
What do you do to protect the area?
By covering it before any work starts. The work is kept contained and leave the area clean.
Do we have to follow TR19 by law?
No. It’s the benchmark rather than the law. Without TR19 records, an insurance claim can be reduced or refused, so following it is the sensible course.
Where does the waste go?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. We don’t leave it behind.
Leave it or put it right?
Don’t wait for an EHO visit or insurance renewal to find gaps in your extract records. A recent inspection report means you are ready when asked. Our emergency line runs 24/7, but a planned visit to Westwick Row is calmer for everyone.
What you pay reflects the actual work. That’s why we survey first, from photos or on site, and why the quote is fixed before any work starts.

Aftercare tips
No system stays clean for ever, but care slows the build-up. Our tips:
- Keep grease filters clean and fitted properly
- Mention new equipment or longer hours at the next test
- Book the next test on the date in the report
- Don’t box in or cover duct access panels
If any reading is 500 microns or more, the report flags it for immediate spot cleaning, and we can quote to do it.
Close the access gaps found during inspection, so every part of the duct can be cleaned.
Kitchen extracts in Westwick Row
Food Standards Agency records list about 38 cafés, restaurants and staff canteens and about 19 takeaways in Westwick Row and the streets around it, up to about 1.5 miles out. A WFTT or DTT reading tells each of those kitchens whether its grease is staying under the 200-micron mean. In Westwick Row, food businesses are inspected by environmental health officers from Dacorum council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Keeping each certificate and photo report on file helps show the extract is looked after. Westwick Row is covered by Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
Church and community hall kitchens, near Church of Holy Trinity or anywhere around Westwick Row, are easy to forget, but their extracts collect grease like any other. Term dates shape school work: for a school like Leverstock Green Church of England Primary School, an extract clean fits neatly into a half-term or summer break.

Vertical risers
Risers in multi-storey buildings can pass through other areas, so access is planned in advance.
