TR19 Inspection in Bishop's Stortford
Need TR19 inspection in Bishop's Stortford? We diagnose first, fix the price and book the work around your hours, finishing with a written report and pictures.
- Uncertainty over how often to clean
- Confirming a clean reached the whole system
- Heavy grease suspected in the plenum or ducts
In-house cleaning or a specialist?
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
TR19 inspection in Bishop's Stortford, done properly
Before any clean in Bishop's Stortford, we survey the canopy, plenum, filters, ducts, fan and discharge. We check where the access panels are and whether every section can be reached, and record grease readings at set points. Common call-outs are for post-clean verification after another contractor’s clean and cleaning intervals that may not suit the kitchen, across pre-clean surveys, access surveys and wet film thickness tests.
Kitchens in towns like Bishop's Stortford are often in older buildings that were never designed for them, so duct runs can be awkward, with bends, long horizontal sections and too few access panels. Where the duct can’t be reached, new panels can be fitted, and anything left uncleaned is recorded on the report.
Every visit ends with a written report and pictures, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

When to call us in Bishop's Stortford
Some parts of a system are hard to reach, and grease can be missed there clean after clean. A survey finds the sections that can’t be reached, so panels can be fitted.
It’s time to book a visit if you see:
- Pre-clean surveys before a first TR19 clean
- Uncertainty over how often to clean
- Missing TR19 certificates or history
- Insurers asking for TR19 evidence
A kitchen near Bishops Stortford station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval.

When it’s something else
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- Fan breakdowns, which need a repair visit
- The grease itself, which needs a full or spot clean
- Hidden runs that need access panels first
If you are not sure, just call 0345 646 2711 or use the quote form and we will give you a straight answer before booking.

How the visit works
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes an hour or two for a single kitchen, longer for a large or complex system. A closed day, an evening or an early start: whichever suits your site in Bishop's Stortford, we will book around it.
- We go through any past certificates and reports.
- We follow the extract from canopy to discharge.
- We note where access panels are and where more are needed.
- Grease readings are taken and photos recorded.
- We report back with readings and a fixed quote.
Preparing for the visit
- Make sure equipment near the work can be switched off and left to cool
- Let us know about permits to work or site inductions
- Make sure someone can let us in and lock up afterwards
Getting 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, you get a fixed price before any work starts.

The FSA’s food hygiene register shows about 88 restaurants, cafés and works canteens and about 32 takeaways and sandwich shops within 1.5 miles or so of the middle of Bishop's Stortford. A WFTT or DTT reading tells each of those kitchens whether its grease is staying under the 200-micron mean. Environmental health officers from East Hertfordshire council inspect food businesses in Bishop's Stortford. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Before-and-after photos from each clean are a simple way to show the extract is in hand. Hertfordshire Fire and Rescue Service covers Bishop's Stortford. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.

Part by part
Extract fan and discharge
A greasy fan works harder and wears faster. The inspection shows whether it needs cleaning now.
Restaurants, pubs and hotels
BESA’s minimum for heavy use of 12 to 16 hours a day is a clean every 3 months, and readings show whether that is enough.
Leave it or put it right?
A check after cleaning shows whether the work reached every part it should have, before the next clean is due. Nothing in a duct, damper or fan improves by being left.
What you pay depends on how big the system is, what state it’s in and how easy it is to reach. You get a fixed price before we start, so there are no surprises.

How do you keep the site clean during the work?
By covering it before any work starts. We keep the work contained and clean down when we finish.
What happens on a pre-clean survey?
The survey covers the whole system, grease readings and access to each section. It lets us plan the clean and give you a fixed quote.
Is a quote from pictures possible?
Yes, if we can see what we need. If not, a site survey comes first, then a fixed quote.

Multi-site and managed buildings
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.
We also work for facilities teams across offices, schools and healthcare across Hertfordshire. Larger estates can be phased building by building around the people who use them.
