TR19 inspection in Riverhead
Before any clean in Riverhead, we survey the canopy, plenum, filters, ducts, fan and discharge. Access is checked along the full length, and grease readings are taken at set points. Typical jobs include kitchens taken over with no cleaning records and systems that need surveying before cleaning, on insurer audits, pre-clean surveys and access surveys.
In a smaller place like Riverhead, many kitchens sit in older buildings or later extensions, with the duct running through a roof space or up an outside wall. Long horizontal runs like that hold grease and need access panels to reach.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

How the job changes from site to site
Canopy and plenum
Clean-looking filters do not mean a clean plenum. So we measure behind the filters, not just in front.
Extract fan and discharge
We look at where the extract discharges outside, as grease can build up there too.
TR19 inspection around Riverhead
Food Standards Agency records list about 54 cafés, restaurants and staff canteens and about 20 takeaways and sandwich shops within 1.5 miles or so of the middle of Riverhead. A WFTT or DTT reading tells each of those kitchens whether its grease is staying under the 200-micron mean. The fire and rescue service for Riverhead is Kent Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. Environmental health officers from Sevenoaks council inspect food businesses in Riverhead. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Keeping each certificate and photo report on file helps show the extract is looked after.
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Sevenoaks Hospital is the nearest hospital to Riverhead, about 1.1 miles east. Volunteers running a hall kitchen near Church of St Mary, or anywhere in Riverhead, may not know when the extract was last cleaned, and a grease test settles it.
Riverhead is about 1 mile west of Sevenoaks, in Kent. Across the TN13 area, we cover TR19 inspection for commercial sites. Riverhead is one of 922 towns, villages and districts in Kent we cover for commercial clients. There’s also a page for Maidstone, roughly 15 miles from Riverhead.

Common questions in Riverhead
Which fire and rescue service is responsible for Riverhead?
That’s Kent Fire and Rescue Service. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Can the work in Riverhead be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. The work in Riverhead can fit around your hours. Let us know the hours you’re closed and we will book within them.
Can one contract cover all our sites?
Yes. We work across South East England and London, so we can schedule a run of sites as one programme. Each site gets its own report and photos.
Do you have a 24/7 line?
Yes. Our emergency line runs 24/7, for problems that cannot wait. Ring any time and tell us what’s happened.
Do you cover Riverhead?
Yes. We work in Riverhead and the rest of Kent, as part of our work across South East England and London. For a fixed quote, phone us on 0345 646 2711, or email photos.
What is grease thickness testing?
Readings are taken using the Wet Film Thickness Test or the Deposit Thickness Test, then compare them with the TR19® Grease figures.
Where does the waste go?
It’s contained and taken away. We collect grease, debris and waste water as we go rather than letting it spread.
What does a pre-clean survey involve?
A survey finds out how the system is laid out, how dirty it is and what can be reached, before anyone starts cleaning. Missing access panels are noted ahead of the clean.
Multi-site and managed buildings
Keeping records across a portfolio is half the battle. Each visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.
For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.
Why deal with it now?
After an incident, an insurer can ask to see proof of TR19 cleaning and inspection. Missing records can put a claim at risk. Getting an inspection done now starts that paper trail. Booking now means the visit to Riverhead is planned around you, not forced by a breakdown.
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll go through it with you.

The process
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before work begins, and the area around the work is covered and protected. The work itself takes around an hour or two per canopy and duct system. We plan the journey to Riverhead and bring what the job is likely to need.
- We go through any past certificates and reports.
- 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.
Preparing for the visit
- Mention any parking or loading restrictions
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Let us know about permits to work or site inductions
Getting a quote
Here’s what helps us quote: where the site is, what it is and its opening hours, photos of the system and any previous report or certificate. Then call 0345 646 2711, or email photos.

Common problems we fix in Riverhead
Kitchens change: a new menu, longer hours or more frying can all add grease. A cleaning interval set years ago may no longer fit.
Most sites get in touch when they notice one of these:
- Kitchens taken over with no cleaning records
- Heavy grease suspected in the plenum or ducts
- Insurers asking for TR19 evidence
- Post-clean verification after another contractor’s clean
Term dates shape school work: for a school like Amherst School, an extract clean fits neatly into a half-term or summer break.
What your quote should include

What staff can safely do
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
