Kitchen extracts in Burnham Green
Food Standards Agency records list about 7 restaurants, cafés and works canteens across Burnham Green and its immediate surroundings (about a mile and a half). Where they cook under a canopy, a grease reading is the way to tell whether the extract is due a clean. Kitchens in Burnham Green get their food hygiene inspections from East Hertfordshire council. Extraction counts as kitchen equipment, so its condition can come up on the day. Our report lists what was cleaned and when, which is useful to have ready. Fire safety in Burnham Green falls to Hertfordshire Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
Bursars and site managers at schools such as Monk's Walk School tend to book extract cleaning for when the kitchen is empty. Digswell House, about 1.9 miles south-west, is one of the historic houses near Burnham Green; if you run event catering at a venue like that, cleans can be booked between functions.

How we handle TR19 inspection in Burnham Green
BESA sets minimum cleaning intervals by daily use: 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. Typical jobs include systems that need surveying before cleaning and an insurer’s request for a TR19 audit, on access surveys, insurer audits and post-clean checks.
For a kitchen in or near Burnham Green, the visit is planned around opening hours and the journey, and the clean itself is the same full TR19® job as in any town: canopy to discharge, then a TR19® certificate and a photo report.
Good records are part of the job. Each visit is written up with photos, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

Signs you need TR19 inspection in Burnham Green
Looking at a canopy tells you little about what’s in the duct. A system can look clean at the filters and be heavily coated further in, which is why readings matter.
Look out for any of the following:
- Uncertainty over how often to clean
- Sites with gaps in their extract records
- Confirming a clean reached the whole system
- Parts of the system left out of past cleans
Healthcare kitchens, like those at hospitals such as Queen Elizabeth II Hospital (about 3.6 miles south), often cook for long hours, which puts them in BESA’s heavier-use bands.
What your quote should include

What the work involves, part by part
Horizontal duct runs
Grease settles on the floor of horizontal ducts as the air cools. Readings are taken along each run through its access panels.
Extract fan and discharge
We look at where the extract discharges outside, as grease can build up there too.
What happens on the day
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. On site, the work takes a morning or less for one kitchen, more where there are several systems. A few pictures of the system help us make the most of a visit to a place like Burnham Green.
- 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.
- We measure the grease and photograph each point.
- We report back with readings and a fixed quote.
How to prepare
- Make sure equipment near the work can be switched off and left to cool
- Let us know when the site is closed or quiet
- Find the previous report, if there is one

Staff cleaning versus specialist work
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
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.
What happens if it’s left?
Don’t wait for an EHO visit or insurance renewal to find gaps in your extract records. A recent inspection report means you’re ready when asked. It’s worth booking a check, because nobody sees inside a duct day to day.
The cost depends on how big the system is, what state it’s in and how easy it is to reach. You get a fixed price before any work starts, so you know where you stand.

Burnham Green: your questions answered
Do you work in villages like Burnham Green?
Yes, we work in villages as well as towns, and Burnham Green is covered. The journey is planned ahead, so a few details about the route help.
Can you work in Burnham Green outside opening hours?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Your opening times are the first thing we ask for.
Do we have to follow TR19 by law?
No. TR19® is a specification, not a statute. Without TR19 records, an insurance claim can be reduced or refused, so it matters in practice.
How long does a TR19 inspection take?
Testing takes an hour or two for a single kitchen, longer for a large or complex system. Large or multiple systems take longer, so call 0345 646 2711 or email us and we’ll plan it.
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, so the clean goes to plan. Any access problems are flagged ahead of the clean.
What do you do to protect the area?
We cover floors and nearby surfaces with sheeting before any work starts, and waste is contained as we go. At the end, the area is cleaned down.
What information do you need?
Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and any previous paperwork make it quicker. Then give us a ring on 0345 646 2711 or use the quote form.
What is a WFTT or DTT grease test?
Readings are taken using the Wet Film Thickness Test or the Deposit Thickness Test, and set against the TR19® Grease figures.
Keeping the system healthy
Once we’ve finished, these simple steps help:
- Don’t box in or cover duct access panels
- Keep to the recommended interval
- Clean grease off the canopy between professional cleans
- Keep TR19 certificates, readings and reports together
The audit report is set out to pass straight to your insurer or broker, with readings, pictures and any areas not accessible.
Clean, correctly fitted filters stop more grease reaching the duct. Missing or damaged filters let grease straight into the plenum.
