FAQs for Nash Mills
Can a school canteen extract in Nash Mills be done out of term time?
Yes. Half-terms and the summer break are the natural time for school work. With about 15 schools and colleges on the FSA’s register within roughly a mile and a half of Nash Mills, it pays to plan holiday dates ahead. Tell us your holiday dates and we will book the visit for when the site is empty.
Who would carry out a food hygiene inspection at a kitchen in Nash Mills?
Kitchens in Nash Mills are inspected by Dacorum council’s environmental health officers. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Can you inspect our extract for our insurance company?
Yes, anywhere in the area we cover. Share the insurer’s request so the report addresses it.
What about areas you can’t get to?
We never leave them off the paperwork. You’ll know exactly which parts weren’t reached and why, and we can quote to improve the access.
How do you protect the area?
By covering it before any work starts. The work is kept contained and clean down when we finish.
How much does TR19 inspection cost?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote and we will normally reply within one working day.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Do you work with multi-site operators?
Yes. Tell us the addresses and what each needs and you’ll get one fixed quote.
About our TR19 inspection in Nash Mills
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. Those are minimums, and grease readings help set the real interval. If you have kitchens whose menu or hours have changed and sections of duct that can’t be reached, we can put it right.
Kitchens around a place like Nash Mills are often in older buildings or single-storey 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.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

How it works
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool before we start, and floors and nearby surfaces are sheeted. On site, it takes a couple of hours for a typical kitchen extract system. In a smaller place like Nash Mills, parking is rarely the issue, but tell us about gates, roof access and opening hours.
- The visit is arranged for when the kitchen isn’t busy.
- Every part of the system is examined, end to end.
- We take WFTT or DTT readings at set points along the system.
- Each test point and any access problems are photographed.
- You get a report with readings, pictures and recommendations.
How to prepare
- Let us know about permits to work or site inductions
- Clear loose items from the work area
- Dig out any earlier paperwork for the system

For landlords and multi-site operators
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.
We work for landlords, managing agents and facilities managers as well as the people running the site. 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.
Fixed quotes for TR19 inspection in Nash Mills
The survey tells us what the work involves. We look at:
- What state the system is in
- Where the site is and how we reach it
- A single visit or a regular plan
- The scale of the work
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at, and you will get one fixed quote.
Helping us quote
To help us quote quickly, please include:
- Problems your staff have spotted
- A few general shots of the system
- The site address and the type of premises
- Close-ups of filters, grilles, hatches or access panels
Every quote begins with a look at the system, from your photos and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work, before any work starts.
Aftercare tips
A little care between visits keeps the system in better shape. We recommend:
- Keep TR19 certificates, readings and reports together
- Diary the next grease test and clean
- Don’t box in or cover duct access panels
- Share inspection reports with your insurer or broker when asked
After the inspection, we send a report showing each reading, its location and photos. Keep it with your fire safety and TR19 records.
Close the access gaps found during inspection, so every part of the duct can be cleaned.
TR19 inspection around Nash Mills
The FSA’s food hygiene register shows about 44 restaurants, cafés and canteens and about 20 sandwich bars and takeaways within 1.5 miles or so of the middle of Nash Mills. A WFTT or DTT reading tells each of those kitchens whether its grease is staying under the 200-micron mean. Nash Mills is covered by Hertfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Kitchens in Nash Mills get their food hygiene inspections from Dacorum council. 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 healthcare site, such as a hospital like Hemel Hempstead Hospital about 1.7 miles north-west, the extract may need cleaning more often than a part-time kitchen. If you run a church or community hall kitchen, near Church of St Mary or elsewhere in Nash Mills, its extract still collects grease from every lunch and event.

Do you need TR19 inspection in Nash Mills?
Records can go missing when a business changes hands or contractors. Without them, nobody knows how much grease is in the system or when it was last cleaned.
The symptoms we’re asked about most are:
- Surveys needed before quoting a full clean
- Ductwork where grease may be over the TR19 limits
- Kitchens taken over with no cleaning records
- Cleaning intervals that may not suit the kitchen
For schools such as Nash Mills Church of England Primary School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.
Before booking anyone
- Whether the work can be done while the site is closed
- If the quote is a fixed price or an estimate
- Whether a survey comes first
- What’s included in the scope, part by part
What your team can do, and what needs us
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
