TR19 inspection for kitchens and businesses in Denton
Insurance policies often require evidence of TR19® cleaning and inspection. Missing records can lead to a claim being reduced or refused. Our TR19 audits give sites in Denton and across East Sussex a clear record of the system’s condition. Common call-outs are for an insurer’s request for a TR19 audit and missing TR19 certificates or history, on access surveys, insurer audits and pre-clean surveys.
Around a smaller place like Denton, kitchen extracts tend to belong to pubs, cafés, takeaways and school or care home kitchens. Quieter kitchens still collect grease in the duct, just more slowly, so cleaning is planned around how much it cooks and what the readings show.
Good records are part of the job. You get a written report with photos after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

What happens if it’s left?
Catching heavy deposits early keeps the fix small. Ignored, the layer only gets thicker. A site near Denton that has to close at short notice is hard to cover for.
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we will go through it with you.

What affects the cost of TR19 inspection
There’s no set price list, because no two systems are the same. What we look at:
- The times the site is available
- The scale of the work
- The number of sites or systems
- Any permits to work or inductions
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 work begins.
What to send for a quote
Before you ask for a quote, gather:
- The times we could work without disrupting the site
- A few general shots of the system
- Where the site is and what kind of site it is
- Where the plant sits or the system leaves the building, such as a roof or outside wall
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. Then we send a fixed price so you know the cost before work begins.
TR19 inspection in Denton: the local picture
Sea air reaches Denton, which sits within about 2 miles of the coast. Corrosion on the fan housing and cowl is worth a look at every clean, alongside the grease. The FSA’s data shows about 8 pubs, bars and clubs registered within roughly a mile and a half of the centre of Denton. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Food hygiene inspections in Denton are the job of Lewes council’s environmental health team. Extraction counts as kitchen equipment, so its condition can come up on the day. Before-and-after pictures from each clean are a simple way to show the extract is in hand.
If you run a café or takeaway near Newhaven Town station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits. A hospital like Chailey Heritage Marine Hospital, about 1.5 miles south, is the kind of site where a kitchen may cook for patients, staff and visitors all day.
Denton is about 1 mile north-east of Newhaven, in East Sussex. Every kind of commercial site in Denton, TR19 inspection is something we can help with. Visits can be booked for evenings, overnight or weekends so the site keeps running. Denton is one of 289 towns, villages and districts in East Sussex where we work for TR19 inspection. You can also see our page for Brighton, about 9 miles away.
All of BN9 is covered for TR19 inspection, from busy streets to back roads. We cover sites on New Road, Avis Road and Hill Road and the roads around them.

How it works
Everything the job needs comes with us, including protection sheets, the right tools and access kit. You only need to give us clear access and switch off what needs to be off. On site, the work takes around an hour or two per canopy and duct system. For a place like Denton, we load the van from the survey notes so the work can be done in one visit where possible.
- Post-clean verification is booked once the clean is done.
- The same access points are opened up.
- We repeat the WFTT or DTT readings.
- Photos are taken to show the condition after the clean.
- The results are reported, with anything missed flagged.
Getting ready for the visit
- Mention any sign-in, permit or induction we need
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Agree a time when the area can be out of use

Related advice
Different parts, different methods
Horizontal duct runs
Grease can gather thickly at bends and along long runs, well away from where anyone looks.
Restaurants, pubs and hotels
Heavy use under BESA guidance, 12 to 16 hours a day, means a clean at least every 3 months, and readings show whether that is enough.
Common questions in Denton
Which environmental health team covers Denton?
That is Lewes council, whose environmental health officers carry out food hygiene inspections in Denton. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Does being near the coast affect TR19 inspection in Denton?
It can. Being within about 2 miles of the sea means more corrosion on metalwork in Denton than inland. A fan housing that is rusting near the coast can fail sooner, so it’s worth catching early.
Are you accredited?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.
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.
Can you set up regular visits?
Yes. Tell us what you have and how it’s used, and we will suggest a schedule and quote for 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 work begins.
How do you keep the site clean during the work?
With sheeting and covers, before anything else happens. We keep the work contained and leave the area clean.
What do you do with what you remove?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. We don’t leave it behind.

Looking after it afterwards
To keep the system working properly between visits:
- Keep grease filters clean and fitted properly
- Tell us if menus or opening hours change
- Keep canopy edges and gutters wiped down
- Report grease dripping from the canopy
Each report suggests the next clean and the next test, based on the readings and how the kitchen is used.
Revisit the cleaning interval whenever the menu or hours change. A quick grease test answers the question.
When it’s something else
We’d rather tell you now than book work that will not help, so these are the things it won’t cover:
- Mechanical faults in the extract
- Removing the grease, which is a separate clean
- Sections with no access, until panels are fitted
Not sure which it is? You can call us on 0345 646 2711 or drop us a line and we will tell you honestly.

Do you need TR19 inspection in Denton?
Menus, opening hours and cooking styles change over time, and more frying or longer hours mean more grease. A cleaning interval set years ago may no longer fit.
Look out for these warning signs:
- Parts of the system left out of past cleans
- Uncertainty over how often to clean
- Post-clean verification after another contractor’s clean
- Ductwork where grease may be over the TR19 limits
Term dates shape school work: for a school like Denton Community Primary School and Nursery, an extract clean fits neatly into a half-term or summer break.
Questions to ask before booking
- Whether the price is fixed
- Whether they’re fully insured
- Whether the work can be done while the site is closed
- Whether inaccessible sections are listed on the report
