How we handle TR19 inspection in Codicote Bottom
Post-clean verification is a check carried out once the cleaning is done, with fresh grease readings, pictures and a look at the areas that were cleaned. It gives you evidence of how the system was actually left. If you have missing access panels found on survey and cleaning intervals that may not suit the kitchen, we can help.
Somewhere as small as Codicote Bottom, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Every one of them still needs its extract kept clear of grease, whatever the size of the place.
It’s worth checking any contractor’s accreditations. We’re 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 affects the cost of TR19 inspection
Every site gets its own quote. This is what makes a difference:
- The number of sites or systems
- Travel, parking and unloading
- How easy every part is to reach
- The condition of the system
A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. The price is fixed before work begins.
What to send for a quote
Photos and a few facts are often enough to price the work. Useful things to send:
- Close-ups of filters, grilles, hatches or access panels
- The site address and the type of premises
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The paperwork from the last visit, if you have it
There’s no standard price list, because no two systems are the same. We look at your system first, from pictures or on a visit, and then send you a fixed quote. To get going, ring 0345 646 2711 or drop us a line.
How the visit works
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. The visit takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. In a small place like Codicote Bottom, the journey is planned ahead and the visit arranged around the site’s hours.
- 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.
- Grease readings are taken and photos recorded.
- We report back with readings and a fixed quote.
Getting ready for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Tell us about site rules, permits or sign-in
- Agree a time when the area can be out of use
How to get a quote
Getting a quote does not take long. Call or email with a few details and you’ll typically have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.

Your questions about TR19 inspection in Codicote Bottom
Can you come to Codicote Bottom after we close?
Yes, nights and weekends are routine for us. The site is handed back ready to open. Your opening times are the first thing we ask for.
Do you clean school canteen extracts around Codicote Bottom out of term?
Yes. The holidays are the usual time for school work. Food Standards Agency records list about 4 schools, colleges and universities with registered kitchens within about a mile and a half of Codicote Bottom. You can ring 0345 646 2711, or send details by email with the dates the site is empty.
How much notice should we give?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
Is TR19 a legal requirement?
No, TR19® isn’t legislation. The Fire Safety Order 2005 still requires the responsible person to manage fire risk, which in a kitchen includes grease in the extract. Many insurers also expect TR19 cleaning.
What should I send you?
Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and the last report help too. Then call us on 0345 646 2711 or send us an email.
How often should a kitchen extract be inspected?
That varies with the kitchen’s daily use. BESA’s minimum cleaning intervals are every 3, 6 or 12 months for heavy, moderate and light use, and grease readings help set the real interval.
Do you check other contractors’ cleans?
It’s an inspection after cleaning, to show what state the system was left in, for our cleans and other firms’ alike.
What happens on a pre-clean survey?
A survey finds out how the system is laid out, how dirty it is and what can be reached, before anyone starts cleaning. Any access problems are flagged ahead of the clean.
In-house cleaning or a specialist?
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
TR19 inspection in Codicote Bottom: the local picture
Food Standards Agency records list about 4 cafés, restaurants and staff canteens in and around Codicote Bottom, up to about a mile and a half out. Kitchens like these cook for very different hours, and grease testing shows which extracts need cleaning soonest. Food hygiene inspections in Codicote Bottom are the job of North Hertfordshire council’s environmental health team. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Our report lists what was cleaned and when, which is useful to have ready. The fire and rescue service for Codicote Bottom is Hertfordshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.

Aftercare tips
Results last longer with the right care. Here’s what we suggest:
- Clean or swap grease filters as often as the kitchen needs
- Book the next test on the date in the report
- Don’t box in or cover duct access panels
- Wipe the canopy surfaces regularly
You get a report with the grease readings, where they were taken and photos of each point. File it alongside your TR19 certificates.
Keep certificates, reports and readings in one place so the history is easy to show.
Why act early in Codicote Bottom
Post-clean verification shows whether the system was left the way the certificate says, while there’s still time to put anything right. Out of sight is the usual reason a rural system goes too long without attention.

Do you need TR19 inspection in Codicote Bottom?
As hot, greasy air travels up the duct, it cools and leaves a film behind. It often collects where nobody can see it: the plenum, bends and horizontal runs.
The symptoms we’re asked about most are:
- Systems cleaned on a calendar with no measurements
- Parts of the system left out of past cleans
- Heavy grease suspected in the plenum or ducts
- Confirming a clean reached the whole system
If you look after a school kitchen, at a school such as Codicote Church of England Primary School or anywhere near Codicote Bottom, the holidays are the usual time for a TR19® clean.
