Codicote TR19 inspection
Professional TR19 inspection in and around Codicote, booked around your opening hours and signed off in writing with pictures.
- Systems cleaned on a calendar with no measurements
- Ductwork where grease may be over the TR19 limits
- Post-clean verification after another contractor’s clean
How we handle TR19 inspection in Codicote
After a clean, post-clean verification checks the result, with new readings and photos of the cleaned areas. It shows whether the system was left in the condition the paperwork describes. If you have sites with gaps in their extract records and kitchens whose menu or hours have changed, we can help, from access surveys, deposit thickness tests and post-clean checks onwards.
Around a smaller place like Codicote, kitchen extracts tend to belong to pubs, cafés, takeaways and school or care home kitchens. Quieter kitchens still collect grease in the duct, just more slowly, so the interval is set by hours of use and grease readings.
Every visit ends with a written report and pictures, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Keeping the system healthy
No system stays clean for ever, but care slows the build-up. A few tips:
- Do not box in or cover duct access panels
- Keep TR19 certificates, readings and reports together
- Send TR19 audit reports to your insurer on request
- Flag changes in how much frying the kitchen does
After the inspection, we send a report showing each reading, its location and pictures. Keep it with your fire safety and TR19 records.
Keep all TR19 records together so the history is easy to show.
How the job changes from site to site
Schools, hospitals and care homes
In healthcare and care settings, kitchens may run from early until late. Testing shows if the cleaning interval keeps pace.
Restaurants, pubs and hotels
Kitchens that cook for long hours build up grease faster. Readings show if the cleans are frequent enough.
What affects the cost of TR19 inspection
Your quote is based on your site. We consider:
- How many systems or sites are involved
- How easy every part is to reach
- The size of the system
- The condition of the system
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you’re unsure, call 0345 646 2711, or send details by email and we’ll give you an honest view and a fixed quote.
What we need to know
What to send for a quote:
- Photos showing the whole system and its surroundings
- Any symptoms, from odd noises to smells or leaks
- The postcode and the type of business
- Close-ups of filters, grilles, hatches or access panels
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.
Why act early in Codicote
A pre-clean survey avoids surprises on the night. Access problems are spotted in advance rather than on the night, and the quote reflects the real job. A quieter site near Codicote still needs its system looked after.
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account and give you a fixed price before any work starts.

Do you need TR19 inspection in Codicote?
Some parts of a system are hard to reach, and grease can be missed there clean after clean. A survey finds the sections that can’t be reached, so the gaps can be closed.
Common reasons sites call us are:
- Ductwork where grease may be over the TR19 limits
- Missing access panels found on survey
- Systems that need surveying before cleaning
- Systems cleaned on a calendar with no measurements
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Codicote is Queen Elizabeth II Hospital, about 5 miles south-east.
Questions to ask before booking
- Whether they recommend a next date
- How VAT is shown on the quote
- Whether a written report and photos are included
- What’s included in the scope, part by part
What TR19 inspection looks like in Codicote
The FSA’s data shows about 3 pubs, bars and clubs registered in and around Codicote, up to about a mile and a half out. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. In Codicote, food businesses are inspected by environmental health officers from North Hertfordshire council. 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 is Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
If you look after a school kitchen, at a school such as Codicote Church of England Primary School or anywhere near Codicote, the holidays are the usual time for a TR19® clean. A hall kitchen that only cooks for events, whether near Parish Church of St Giles or elsewhere in Codicote, still needs its extract cleaned, just less often.

What staff can safely do
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
How it works
The first job on site is protection: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. The work on site takes an hour or two for a single kitchen, longer for a large or complex system, and the area is cleaned down before we leave. A site near Codicote usually has room to park, so the questions are about access to the system and your hours.
- After the clean, we arrange a time to check the system.
- The same access points are opened up.
- We repeat the WFTT or DTT readings.
- Photos are taken to show the condition after the clean.
- The results are reported, with anything missed flagged.
Preparing for the visit
- Find the previous report, if there is one
- Allow time for equipment near the work to be turned off and cool down
- Clear loose items from the work area
Getting a quote
Every quote begins with a look at the system, from your pictures and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work, before we start.
