What staff can safely do
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
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.
About our TR19 inspection in Frithsden
Many insurers ask for proof that kitchen extract systems are cleaned and inspected to TR19®. Missing records can lead to a claim being reduced or refused. Our TR19 audits give sites in Frithsden and across Hertfordshire a clear record of the system’s condition. The work covers deposit thickness tests, access surveys and insurer audits, and the jobs we see most are missing access panels found on survey and kitchens whose menu or hours have changed.
In a village or hamlet like Frithsden, the kitchens that need extract cleaning are normally a pub, a school, a care home or a hall kitchen, wherever there is one. Each still has a canopy and duct that collect grease, whatever the size of the place.
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, with full insurance on top.

What else we do in Frithsden
What we do, step by step
There are three stages on the day: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. The middle part takes longest, and that takes a morning or less for one kitchen, more where there are several systems. If you can send photos, we can arrive in Frithsden knowing what to expect.
- We go through any past certificates and reports.
- The layout is traced from the canopy to the discharge.
- Access panels are located and any missing ones noted.
- We measure the grease and photograph each point.
- We report back with readings and a fixed quote.
Preparing for the visit
- Tell us the best time to work, such as after service or at a weekend
- Dig out any earlier paperwork for the system
- Tell us about site rules, permits or sign-in
Getting a quote
Getting a quote does not take long. Call or email with a few details and you’ll usually have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
Advice
Grease, kitchens and Frithsden
Look up Frithsden on the FSA’s food hygiene register and you will find about 5 cafés, restaurants and staff canteens across Frithsden and its immediate surroundings (about a mile and a half). For any of them with a canopy, measuring grease is better than guessing when to clean. Frithsden sits within the area of Hertfordshire Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. Kitchens in Frithsden get their food hygiene inspections from Dacorum council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Our report lists what was cleaned and when, which is useful to have ready.
For schools such as Potten End CofE Primary School, kitchen extract cleaning is typically booked for the holidays, when the canteen is closed. A hospital like Hemel Hempstead Hospital, about 3.1 miles south-east, is the kind of site where a kitchen may cook for patients, staff and visitors all day. A hall kitchen that only cooks for events, whether near Church of St Lawrence or elsewhere in Frithsden, still needs its extract cleaned, just less often.
Frithsden is about 2 miles north-east of Berkhamsted, in Hertfordshire. Sites in Frithsden get the same service as everywhere we cover: a survey first, a fixed quote, work timed around your hours and a report with pictures. We cover 381 places across Hertfordshire, from busy centres to quieter spots. You can also see our page for Milton Keynes, about 21 miles away.

When something else is needed
In fairness, some problems need a different fix:
- Parts of the duct nobody can reach yet
- Fan breakdowns, which need a repair visit
- The legal duty, which stays with the responsible person
Not sure which it is? You can call us on 0345 646 2711, or email photos and we’ll tell you honestly before you book.

Why book with us
- A BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease
- Accredited under CHAS and SafeContractor, with ISO 9001

- A written report with pictures after every visit
What affects the quote in Frithsden
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Access, including roofs, risers and ceiling voids
- The scale of the work
- Any permits to work or inductions
- The times the site is available
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are unsure, call 0345 646 2711 or send us an email for straight advice and a fixed quote.
What we need to know
Photos and a few facts are often enough to price the work. Send what you can of the following:
- Any access panels or hatches you can see
- Problems your staff have spotted
- The site address and the type of premises
- Your opening hours and when the area is out of use
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 send you a fixed quote. To get going, phone us on 0345 646 2711 or use the quote form.
FAQs for Frithsden
Who inspects food businesses in Frithsden?
Kitchens in Frithsden are inspected by Dacorum council’s environmental health officers. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Do you cover smaller places like Frithsden?
Yes, we work in villages as well as towns, and Frithsden is covered. A survey first, from photos or a visit, means we arrive with the right kit.
What information do you need?
A short description and a few photos plus the address and your hours. If we need more, we’ll ask.
Can you set up regular visits?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
How long does grease testing take?
Expect it to take anything from an hour for a small canopy and short duct to a good part of a day for a large site. We fit it around when the kitchen is closed or quiet.
Is there a survey before the work?
Yes. For many sites, photos and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
What happens if you can’t reach some of it?
Anything we cannot reach goes on the report, with pictures where possible, and we tell you what would make it reachable, for example new access panels.
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. A risk assessment based on measured grease should set the interval.
Different parts, different methods
Vertical risers
Access to risers is often limited. The survey shows exactly what access there is.
Horizontal duct runs
Bends and long runs can hold heavy deposits, well away from where anyone looks.
Keeping the system healthy
No system stays clean for ever, but care slows the build-up. A few tips:
- Flag oily drips near the extract
- Flag changes in how much frying the kitchen does
- Have the latest report ready for insurance renewals
- Never cook with filters missing
The report recommends when the system should next be cleaned and tested, based on the readings and how the kitchen is used.
Test grease regularly instead of relying on the calendar. It shows if build-up is speeding up.
