Hexton questions
Can you come to Hexton after we close?
Yes. We work evenings, overnight and at weekends. It means the site in Hexton keeps running as normal. Your opening times are the first thing we ask for.
Can school kitchens in Hexton be cleaned in the holidays?
Yes, holiday work suits schools best. With about 2 schools and colleges on the FSA’s register within roughly a mile and a half of Hexton, it pays to plan holiday dates ahead. Send us your term dates when you call 0345 646 2711 or send us an email, and we will fit the work in.
Can we book visits on a schedule?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. The report from each visit recommends the next date.
Can you quote from pictures?
Typically, yes. Send wide shots, close-ups of any access panels and anything that worries you, and we usually come back within one working day. Some sites still need a visit, and we’ll say so.
When should we have our next grease test?
Each report recommends when to test and clean next, taking the readings and the kitchen’s hours into account. The interval should come from a competent person’s risk assessment backed by grease measurement.
At what point does grease need cleaning?
The TR19® Grease figures are a mean of 200 microns or less between cleans, and immediate spot cleaning wherever a reading hits 500 microns. We show your readings against those figures.
How long does a TR19 inspection take?
Testing takes around an hour or two per canopy and duct system. Large or multiple systems take longer, so call 0345 646 2711 or send us an email and we’ll plan it.
What does TR19 inspection cost?
We do not publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. You get a fixed price before we start.
TR19 inspection in Hexton, done properly
TR19® Grease says grease should not exceed a mean of 200 microns between cleans, while a reading of 500 microns or more anywhere calls for immediate spot cleaning. Testing is how you know where your system stands. If you have surveys needed before quoting a full clean and systems cleaned on a calendar with no measurements, we can help.
In a small place like Hexton, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. We agree access and timings in advance.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

What staff can safely do
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That’s our job.
How the visit works
Each visit runs to the same pattern: protect the area, make the system safe, carry out the TR19 inspection, clear away and leave you the report. On site, the work takes around an hour or two per canopy and duct system. A few photos of the system help us make the most of a visit to a place like Hexton.
- 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 pictures recorded.
- You get a report and a fixed quote for the clean.
Preparing for the visit
- Arrange a key holder or contact on site
- Move anything stored near the system
- Let us know how we reach the system, including roofs, risers and plant rooms
How to get a quote
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before any work starts.

What happens if it’s left?
After an incident, an insurer can ask to see proof of TR19 cleaning and inspection. Without them, a claim can be reduced or refused. Getting an inspection done now starts that paper trail. With notice, the visit to Hexton can be fitted around your bookings and events.
The cost depends on how big the system is, the condition it’s in and access to every part of it. You get a fixed price before we start, so there are no surprises.

What we are called out for in Hexton
Some parts of a system are hard to reach, and grease can be missed there clean after clean. An inspection of a system in Hexton shows where access panels are missing, so panels can be fitted.
What we’re most often called out for:
- Kitchens whose menu or hours have changed
- Extracts that have never been grease tested
- Heavy grease suspected in the plenum or ducts
- Surveys needed before quoting a full clean
Healthcare kitchens, like those at hospitals such as Keech Hospice Care (about 3.2 miles south-west), often cook for long hours, which puts them in BESA’s heavier-use bands.
What to look for in a quote
- What happens if part of the system cannot be accessed
- What hours they’ll be on site
- Exactly which parts of the system are covered
- Whether they recommend a next date
Aftercare tips
Think of this as the after-treatment advice, short and simple:
- Never cook with filters missing
- Flag changes in how much frying the kitchen does
- Diary the next grease test and clean
- Do not box in or cover duct access panels
For an insurer audit, send them the report as it is, with readings, pictures and any areas not accessible.
Keep all TR19 records together so you can produce them quickly.
TR19 inspection around Hexton
There are about 6 cafés, restaurants and staff canteens within 1.5 miles or so of the middle of Hexton, according to the Food Standards Agency’s register. For any of them with a canopy, measuring grease is better than guessing when to clean. Fire safety in Hexton falls to Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. In Hexton, food businesses are inspected by environmental health officers from North Hertfordshire council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A dated certificate in the maintenance file answers the question before it’s asked.
Volunteers running a hall kitchen near Church of St Faith (Church of England), or anywhere in Hexton, may not know when the extract was last cleaned, and a grease test settles it. If you run catering at a historic house or estate in the area (Harlington Manor is about 4.3 miles west), event kitchens in older buildings often have awkward duct runs that need planning.
