TR19 inspection in Langenhoe, done properly
A grease test measures how thick the grease is inside a kitchen extract system. Readings are taken at set points using the Wet Film Thickness Test (WFTT) or the Deposit Thickness Test (DTT). The results show whether the system needs cleaning and how soon. If you have kitchens taken over with no cleaning records and kitchens whose menu or hours have changed, we can put it right, from pre-clean surveys, wet film thickness tests and deposit thickness tests onwards.
Somewhere as small as Langenhoe, 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.
Think of the report as the system’s health record: a dated account with photos of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

Kitchen extracts in Langenhoe
At about 2 miles from the coast, Langenhoe is close enough for sea air to matter. Near the sea, the fan and discharge at the top of a kitchen extract corrode faster than they would inland. In Langenhoe, food businesses are inspected by environmental health officers from Colchester council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Keeping each certificate and photo report on file helps show the extract is looked after. Essex County Fire and Rescue Service covers Langenhoe. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
If you run a church or community hall kitchen, near Church of St Andrew or elsewhere in Langenhoe, its extract still collects grease from every lunch and event. A hospital like Essex County Hospital, about 4.1 miles north, is the kind of site where a kitchen may cook for patients, staff and visitors all day.
Langenhoe is about 4 miles south of Colchester, in Essex. Langenhoe gets the same approach as every site we work on: diagnosis first, a fixed price, out-of-hours working where needed and a written report with photos.

What happens if it’s left?
Catching heavy deposits early keeps the fix small. Ignored, the layer only gets thicker. Equipment tucked in a roof space or outbuilding near Langenhoe rarely gets looked at unless someone books it.
What you pay depends on how big the system is, the condition it’s in and how easy it is to reach. You get a fixed price before any work starts, so you know where you stand.

The process
We’re used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. On site, the work takes a morning or less for one kitchen, more where there are several systems. Pictures of the system and its access let us plan the work in Langenhoe before we set off.
- First we look at the system’s cleaning history, if there is one.
- We follow the extract from canopy to discharge.
- We note where access panels are and where more are needed.
- Grease readings are taken and pictures recorded.
- You get a report and a fixed quote for the clean.
Before we arrive
- Name a contact who can let us in at the agreed time
- Let us know when the site is closed or quiet
- Let us know about parking and loading
Getting a quote
The quickest way to a quote is to send pictures: 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.

Fixed quotes for TR19 inspection in Langenhoe

Working hours, access and the scale of the site can all change the price. We take each of them into account and give you a fixed price before we start.
What to send for a quote
To speed up the quote, send us:

Langenhoe questions
Who would carry out a food hygiene inspection at a kitchen in Langenhoe?
In Langenhoe, it’s Colchester council that carries out food hygiene inspections. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Which fire service covers Langenhoe?
That is Essex County Fire and Rescue Service. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
How do you measure grease in a kitchen extract?
Grease thickness testing measures the layer of grease on the duct surfaces, by WFTT or DTT. Each reading is recorded in microns.
Can you verify a clean after it’s been done?
Verification means repeat readings and photos once the clean is done. The report flags anything missed.
What is TR19?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
What if parts of the system can’t be reached?
Anything we cannot reach goes on the report, with photos where possible, and we tell you what would make it reachable, such as extra access panels in ductwork.
How often should grease be tested?
Each report recommends when to test and clean next, taking the readings and the kitchen’s hours into account. A risk assessment based on measured grease should set the interval.
What grease levels does TR19 allow?
The TR19® Grease figures are a mean of 200 microns or less between cleans, and immediate spot cleaning wherever a reading hits 500 microns. Our report sets your readings against both.
Common problems we fix in Langenhoe
Looking at a canopy tells you little about what’s in the duct. Clean filters can hide a heavy layer behind them, which is why readings matter.
Common reasons sites call us include:
- Checking the result of a recent clean
- Uncertainty over how often to clean
- Surveys needed before quoting a full clean
- Ductwork where grease may be over the TR19 limits
For schools such as Langenhoe Community Primary School and Pre-School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed.
What to look for in a quote

- What hours they’ll be on site
- How VAT is shown on the quote
- What paperwork you get at the end
Different parts, different methods
Restaurants, pubs and hotels
Kitchens that cook for long hours build up grease faster. Readings show if the cleans are frequent enough.
Schools, hospitals and care homes
We fit testing around service times and school holidays so meals are not affected.
Multi-site and managed buildings
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side, and the report can go to both.
