Betsham TR19 inspection
We cover Betsham for TR19 inspections, grease thickness testing, pre-clean surveys and post-clean verification. Out-of-hours visits, a fixed quote and a written report with pictures on every job.
- Extracts that have never been grease tested
- Surveys needed before quoting a full clean
- An insurer’s request for a TR19 audit
How we handle TR19 inspection in Betsham
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. The work covers access surveys, deposit thickness tests and pre-clean surveys, and the jobs we see most are sites with gaps in their extract records and uncertainty over how often to clean.
In a village or hamlet like Betsham, the kitchens that need extract cleaning are normally a pub, a school, a care home or a hall kitchen, wherever there is one. Each still has a canopy and duct that collect grease, whatever the size of the place.
The paperwork matters as much as the work. Each visit is written up with photos, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

Staff cleaning versus specialist work
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Betsham: your questions answered
Who is the fire and rescue service for Betsham?
It’s Kent Fire and Rescue Service, which covers Betsham. TR19® isn’t law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Can school kitchens in Betsham be cleaned in the holidays?
Yes. Half-terms and the summer break are the natural time for school work. There are about 11 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Betsham. Send us your term dates when you call us on 0345 646 2711 or email us, and we’ll fit the work in.
How much does TR19 inspection cost?
The cost depends on the size of the system, its condition, access and timing. Ask us for a fixed quote and we’ll usually reply within one working day.
How do you keep the site clean during the work?
We cover floors and nearby surfaces with sheeting before any work starts, and waste is contained as we go. Before we leave, we tidy up and clean down.
How much notice do you need?
For planned work, earlier is better, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
Can you work evenings and weekends?
Yes. Evenings, nights and weekends are normal working hours for us, so you do not have to close during trading.
What happens if you can’t reach some of it?
The report shows them clearly. In ductwork, new access panels are often the answer, which we can install.
Do you survey before quoting?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
Different parts, different methods
Extract fan and discharge
We look at where the extract discharges outside, as grease can build up there too.
Vertical risers
In buildings with several floors, the riser may pass through other tenants’ space, so we arrange access ahead of time.
Kitchen extracts in Betsham
Food Standards Agency records include about 8 bars, pubs and nightclubs in and around Betsham, up to about a mile and a half out. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Betsham sits within the area of Kent Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. Food hygiene inspections in Betsham are the job of Dartford council’s environmental health team. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Our report lists what was cleaned and when, which is useful to have ready.
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Cobham College is about 4.4 miles south-east), access may need planning. If you run a church or community hall kitchen, near Church of St Nicholas or elsewhere in Betsham, its extract still collects grease from every lunch and event. Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Betsham is Darent Valley Hospital, about 2.4 miles north-west.
Betsham is about 2 miles south-west of Northfleet, in Kent. Anywhere in DA13, we can take on TR19 inspection. Across Kent, we cover 922 places, Betsham among them. Maidstone is in our area too, about 14 miles from Betsham.
Work in DA13 follows the same survey, fixed quote and written report as everywhere else we cover. Whether your site is on Station Road, Crayburne and Park Corner Road or a nearby road, we can help. Betsham is on the B262, which makes it straightforward for our technicians to reach for out-of-hours visits. Neighbouring places we cover for TR19 inspection include Hook Green (1 mile south-east), Southfleet (1 mile south-east), Springhead (1 mile north-east), Ebbsfleet Valley (1 mile north) and Northfleet Green (1 mile east). Further out, we also cover Maidstone (14 miles south-east), Dartford (4 miles north-west), Sevenoaks (11 miles south-west), Gravesend (3 miles east), Tonbridge (15 miles south) and Swanley (6 miles west).

Open spaces near Betsham include Chafford Gorges Nature Park and Sawyers Lake.
What happens on the day
A visit follows the same order every time: protect the area, isolate whatever needs isolating, carry out the TR19 inspection, tidy up and hand over the paperwork. The visit itself takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. Somewhere as small as Betsham, the date and timings are agreed with you well before the day.
- We agree a time when the kitchen is closed or quiet.
- The system is checked from canopy to discharge.
- We take WFTT or DTT readings at set points along the system.
- Each test point and any access problems are photographed.
- We send a report setting out the readings, pictures and next steps.
Before we arrive
- Arrange a key holder or contact on site
- Move anything stored near the system
- Mention any sign-in, permit or induction we need
Ask for a quote
Quoting starts with a diagnosis, from your pictures and details or, where that isn’t enough, a survey on site. Then we send a fixed price, before work begins.

Looking after it afterwards
To keep the system working properly between visits:
- Keep access panels clear and unpainted
- Book the next test on the date in the report
- Keep grease filters clean and fitted properly
- Flag oily drips near the extract
Where sections couldn’t be reached, the report says where access panels would help. With panels fitted, the next clean can cover every section.
Close the access gaps found during inspection, so every part of the duct can be cleaned.
What a clean will not put right
We’ll always give you a straight diagnosis, so here’s what TR19 inspection will not do:
- Sections with no access, until panels are fitted
- Removing the grease, which is a separate clean
- The legal duty, which stays with the responsible person
If in doubt, give us a ring on 0345 646 2711 or drop us a line and we will say what we think.
Parts of the system we cover
- Post-clean checks

What affects the cost of TR19 inspection
The survey tells us what the work involves. We look at:
- Travel, parking and unloading
- Whether it’s a one-off visit or part of a schedule
- The size of the system
- Working hours and out-of-hours timing
We do not list prices on the website, because each job is priced on what it involves. Call for a fixed quote, and we will talk you through it.
What to send for a quote
Many jobs can be priced from photos and some basics. Useful things to send:
- Detail shots of panels, filters and grilles
- Wide pictures of the system and the area around it
- Where the site is and what kind of site it is
- Any symptoms, from odd noises to smells or leaks
If you need TR19 inspection in Betsham, ring 0345 646 2711 or drop us a line. Tell us what kind of premises it is and when it’s open, plus photos or the previous report if they’re to hand. A fixed quote usually follows within one working day.
Why deal with it now?
If there’s a fire or a claim, your insurer may ask for TR19 records. Without them, a claim can be reduced or refused. Getting an inspection done now starts that paper trail. In a place like Betsham, ductwork and fans are easy to forget until something goes wrong.
Working hours, access and the scale of the site all affect the cost. We take each of them into account and give you a fixed price before work begins.
