TR19 inspection in Mersham
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’re dealing with cleaning intervals that may not suit the kitchen and extracts that have never been grease tested, we can help, from access surveys, pre-clean surveys and wet film thickness tests onwards.
In a village or hamlet like Mersham, the kitchens that need extract cleaning are usually a pub, a school, a care home or a hall kitchen, wherever there is one. Every one of them still needs its extract kept clear of grease.

What we do, step by step
Protection comes first: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes an hour or two for a single kitchen, longer for a large or complex system, and the area is cleaned down before we leave. Pictures of the system and its access let us plan the work in Mersham before we set off.
- First we book a time that won’t disrupt cooking.
- The system is checked from canopy to discharge.
- We take WFTT or DTT readings at set points along the system.
- We photograph the test points and record any sections we cannot reach.
- You get a report with readings, photos and recommendations.
Getting ready for the visit
- Let us know about permits to work or site inductions
- Allow time for equipment near the work to be turned off and cool down
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

Grease, kitchens and Mersham
Food Standards Agency records list about 5 restaurants, cafés and works canteens in Mersham and the streets around it, up to about 1.5 miles out. Each kitchen extract among them can be measured for grease to set the right cleaning interval. The fire and rescue service for Mersham is 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. Environmental health officers from Ashford council inspect food businesses in Mersham. 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.
If you run catering at a historic house or estate in the area (Westenhanger Castle is about 4.7 miles east), event kitchens in older buildings often have awkward duct runs that need planning. Healthcare kitchens, like those at hospitals such as William Harvey Hospital (about 1.7 miles north-west), often cook for long hours, which puts them in BESA’s heavier-use bands. Where a hall near Church of St John the Baptist, or anywhere in Mersham, hosts lunch clubs or events, its extract gathers grease just as a café’s does.
Mersham is about 3 miles south-east of Ashford, in Kent. Mersham gets the same approach as every site we work on: diagnosis first, a fixed price, out-of-hours working where necessary and a written report with pictures. Mersham is one of 922 towns, villages and districts in Kent where we work for commercial clients. There’s also a page for Maidstone, about 20 miles away.

In-house cleaning or a specialist?
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.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That’s our job.
Honest limits
We will always give you a straight diagnosis, so here’s what this work cannot put right:
- Mechanical faults in the extract
- The responsible person’s own fire risk assessment
- Installation problems, which fall under design guidance such as DW172
If in doubt, phone us on 0345 646 2711, or send details by email and we will say what we think.

Fixed quotes for TR19 inspection in Mersham
Before we fix a price, we need to know a few things. We check:
- Whether several sites go on one quote
- How big the system is
- The times the site is available
- Parking and loading at the site
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. You’ll have a fixed price before we start.
What to send for a quote
Many jobs can be priced from pictures and some basics. Send what you can of the following:
- Close-ups of filters, grilles, hatches or access panels
- The site address and the type of premises
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Here’s what helps us quote: where the site is, what it is and its opening hours, a few pictures and the last certificate or report, if there is one. Once you have those, call us on 0345 646 2711 or use the quote form.

Different parts, different methods
Extract fan and discharge
The extract fan and its housing collect grease too. We check and test them as part of the inspection.
Schools, hospitals and care homes
Hospital and care home kitchens can cook all day, every day. Readings show if cleaning is frequent enough.
Multi-site and managed buildings
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, 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.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.

Can you work in Mersham outside opening hours?

How often should grease be tested?
Each report recommends when to test and clean next, based on the readings and how the kitchen is used. The interval should come from a competent person’s risk assessment backed by grease measurement.
How much does TR19 inspection cost in Mersham?
There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. We fix the price before any work starts.

How long does a TR19 inspection take?
Typically, the inspection takes a morning or less for one kitchen, more where there are several systems. The size of the system and the access make the difference.
Leave it or put it right?
Without readings, you’re guessing when to clean. Any reading of 500 microns or more needs immediate spot cleaning under TR19® Grease, and you can only act on that if you’ve measured it. If the system at a site near Mersham fails, there may be nowhere nearby to move to.
Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.
