TR19 inspection in Marlow: the local picture
The FSA’s food hygiene register includes about 23 pubs and bars and about 5 hotels and guest houses within 1.5 miles or so of the middle of Marlow. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Food hygiene inspections in Marlow are the job of Buckinghamshire council’s environmental health team. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Before-and-after photos from each clean are a simple way to show the extract is in hand. Fire safety in Marlow falls to Buckinghamshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
A hospital like Marlow Community Hospital, about within half a mile east, is the kind of site where a kitchen may cook for patients, staff and visitors all day. If you look after a school kitchen, at a school such as Holy Trinity Church of England (Aided) School or anywhere near Marlow, the holidays are the usual time for a TR19® clean. If you run a church or community hall kitchen, near Congregational Church or elsewhere in Marlow, its extract still collects grease from every lunch and event.
Marlow is about 4 miles south of High Wycombe, in Buckinghamshire. Whether your site is in the middle of Marlow or further out, we cover TR19 inspection for every kind of premises, from a single unit to a large public building. Marlow is one of 263 places in Buckinghamshire where we work for commercial clients. There’s also a page for Reading, about 12 miles away.

Around Marlow
In Marlow, that means kitchens and buildings near Butcher's Tap and Sir William Borlase's Grammar School, among other places. There’s a railway station in Marlow itself: Marlow station. A little further out are Eden (4 miles north) and High Wycombe Castle (4.1 miles north). The countryside around Marlow includes Carpenter's Wood.
TR19 inspection in Marlow, done properly
BESA’s minimum cleaning frequencies depend on how long the kitchen cooks each day: every 3 months for heavy use of 12 to 16 hours a day, every 6 months for moderate use of 6 to 12 hours, and every 12 months for light use of 2 to 6 hours. Grease testing shows whether your kitchen needs cleaning more often than that. The work covers deposit thickness tests, pre-clean surveys and access surveys, and the jobs we see most are systems that need surveying before cleaning and post-clean verification after another contractor’s clean.
Kitchens in towns like Marlow are often in older buildings that were never designed for them, so duct runs can be awkward, with bends, long horizontal sections and too few access panels. Sections we can’t reach are listed on the report, and access panels can be added.
The paperwork matters as much as the work. You get a written report with pictures after every visit, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Staff cleaning versus specialist work
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Managing agents and facilities teams in Marlow
From a single site to a large estate, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.
Between visits
Here’s the after-treatment advice, short and simple:
- Keep to the recommended interval
- Look out for grease drips round the canopy edge
- Have the latest report ready for insurance renewals
- Do not box in or cover duct access panels
Each report suggests the next clean and the next test, from the measured grease and the kitchen’s hours.
Keep certificates, reports and readings in one place so you can produce them quickly.
Your questions about TR19 inspection in Marlow
Do you work at weekends in Marlow?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Marlow needn’t be disturbed. Tell us your opening hours when you ask for a quote.
Who enforces fire safety at workplaces in Marlow?
Fire safety enforcement in Marlow is handled by Buckinghamshire Fire and Rescue Service. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
How long does grease testing take?
Testing takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. Sites with several canopies take longer, so call us on 0345 646 2711, or send details by email and we will plan it.
What is a WFTT or DTT grease test?
It’s a measurement of how much grease is coating the inside of the extract, by WFTT or DTT. Each reading is recorded in microns.
Do you offer emergency callouts?
Yes, day and night, every day of the year. Our office is open from 8am to 6pm on weekdays, and the emergency line covers the rest.
Is TR19 a legal requirement?
No, TR19® is not legislation. But the responsible person must assess and reduce fire risk under the Fire Safety Order 2005, and grease in the extract is part of that. Many insurers also expect TR19 cleaning.

What else we do in Marlow
How it works
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes a morning or less for one kitchen, more where there are several systems. Sites in a town like Marlow rarely need to lose trading hours, as the work fits around them.
- First we look at the system’s cleaning history, if there is one.
- The layout is traced from the canopy to the discharge.
- We note where access panels are and where more are needed.
- We measure the grease and photograph each point.
- You get a report and a fixed quote for the clean.
How to prepare
- Plan for cooking equipment or plant to be off before we arrive
- Mention any sign-in, permit or induction we need
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
Get a fixed quote
There’s no standard price list, because every site is different. We look at your system first, from photos or on a visit, and then give you a fixed quote. To get going, phone us on 0345 646 2711 or email us.
