Hertfordshire · TR19 inspections and grease testing
TR19 inspections in Kemprow
TR19 inspection for Kemprow, from a team that has been trading since 2009. Out-of-hours visits and 24/7 emergency callout.
- Cleaning intervals that may not suit the kitchen
- Extracts that have never been grease tested
- Missing access panels found on survey
Multi-site and managed buildings
Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
Whether it’s one building or many, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with photos.
TR19 inspection in Kemprow
A fixed schedule doesn’t always match how a kitchen really cooks. Some kitchens build up grease faster than the minimum intervals assume, which is why measurement matters. We give your risk assessment measured figures rather than guesses. The work covers access surveys, pre-clean surveys and deposit thickness tests, and people most often call us about an insurer’s request for a TR19 audit and extracts that have never been grease tested.
Work in a small place like Kemprow starts with a call to agree access and timings, and the clean itself is the same full TR19® job as in any town: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
The report is your system’s health record: dated, with photos, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

The process
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. A few pictures of the system help us make the most of a visit to a place like Kemprow.
- 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.
- We report back with readings and a fixed quote.
Preparing for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Dig out any earlier paperwork for the system
- Clear loose items from the work area
Getting a quote
For a fixed quote, phone us on 0345 646 2711, or send details by email and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. You will usually have a quote within one working day.
Advice
Common problems we fix in Kemprow
When a site in Kemprow changes owner or cleaning contractor, the records do not always follow. With no history, the current state of the extract is a guess.
It’s time to book a visit if you see:
- Systems that need surveying before cleaning
- Insurers asking for TR19 evidence
- Sections of duct that can’t be reached
- Extracts that may be over the 200 micron mean
Term dates shape school work: for a school like Fair Field Junior School, an extract clean fits neatly into a half-term or summer break.
Comparing quotes
- If the quote is a fixed price or an estimate
- If they look at the system before pricing
- How VAT is shown on the quote
- When they can work, and whether that’s outside your opening hours
Keeping the system healthy
Think of this as the after-treatment advice, short and simple:
- Share inspection reports with your insurer or broker when asked
- Wipe the canopy surfaces regularly
- Flag oily drips near the extract
- Keep the route to access panels clear
For an insurer audit, send them the report as it is, with readings, photos and any areas not accessible.
Keep certificates, reports and readings in one place so the history is easy to show.
How the job changes from site to site
Restaurants, pubs and hotels
Heavy use under BESA guidance, 12 to 16 hours a day, means a clean at least every 3 months, and readings show whether that’s enough.
Vertical risers
In buildings with several floors, the riser may pass through other tenants’ space, so access is planned in advance.

What else we do in Kemprow
What happens if it’s left?
Without readings, you are guessing when to clean. 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. With notice, the visit to Kemprow can be fitted around your bookings and events.
What you pay depends on how big the system is, what state it’s in and how easy it is to reach. We give you a fixed price before any work starts, so there are no surprises.
Why us?
- Accredited under CHAS and SafeContractor, with ISO 9001
- A written report with photos after every visit
- BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease
- Survey first, then a fixed quote

FAQs for Kemprow
Do you work at weekends in Kemprow?
Yes, we can come after you close and finish before you open. The work in Kemprow can fit around your hours. Just call us on 0345 646 2711 or email us with your opening times and we will plan around them.
Which fire authority looks after Kemprow?
Hertfordshire Fire and Rescue Service is the fire and rescue service for Kemprow. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
What happens to the waste?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. We don’t leave it behind.
Will you produce a report for our insurer?
Yes. We inspect the system and produce a report with grease readings, photos and any inaccessible areas. You can pass it straight to your insurer or broker.
What is grease thickness testing?
We measure the grease at set points with a WFTT or DTT test, and set against the TR19® Grease figures.
What do the grease readings need to be?
TR19® Grease says grease should not go over a mean of 200 microns between cleans. Any reading of 500 microns or more needs immediate spot cleaning.
What does TR19 mean?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
How far ahead should we book?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.
TR19 inspection in Kemprow: the local picture
The FSA’s food hygiene register includes about 8 bars, pubs and nightclubs and about 3 hotels and B&Bs in and around Kemprow, up to about a mile and a half out. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. In Kemprow, food businesses are inspected by environmental health officers from Hertsmere council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A TR19® certificate and photo report after each clean gives you a record to show an inspector. The fire and rescue service for Kemprow 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.
A hall kitchen that only cooks for events, whether near St John or elsewhere in Kemprow, still needs its extract cleaned, just less often. Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Kemprow is Shenley Hospital, about 2.3 miles north-east.
