Questions from Heath End
Can you come to Heath End after we close?
Yes. We work evenings, overnight and at weekends. It means the site in Heath End keeps running as normal. Your opening times are the first thing we ask for.
Which fire authority looks after Heath End?
Fire safety enforcement in Heath End is handled by Hertfordshire Fire and Rescue Service. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Are you accredited?
We hold CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
Can you inspect our extract for our insurance company?
Yes. Our TR19 audits cover readings, pictures, access and a recommended cleaning interval. It’s set out for your insurer or broker.
What grease levels does TR19 allow?
Under TR19® Grease, the mean thickness should not exceed 200 microns between cleans. 500 microns or more at any point calls for immediate spot cleaning.
Can you price the work without visiting?
Typically, yes. Send wide shots, close-ups of any access panels and anything that worries you, and we typically come back within one working day. If photos are not enough, we’ll survey first.
Is Heath End in your area?
Yes. We cover Heath End and the rest of Hertfordshire, as part of our work across South East England and London. For a fixed quote, call 0345 646 2711 or email us.
Is TR19 cleaning the law?
No. It’s the benchmark rather than the law. In practice, an insurer can refuse or reduce a claim without proof of TR19 cleaning, so it matters in practice.
TR19 inspection in Heath End, done properly
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 Heath End and across Hertfordshire a clear record of the system’s condition. The work covers post-clean checks, insurer audits and access surveys, and the jobs we see most are ductwork where grease may be over the TR19 limits and missing access panels found on survey.
Somewhere as small as Heath End, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Each still has a canopy and duct that collect grease, whatever the size of the place.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Aftercare tips
How long the results last depends on use and care. We suggest:
- Flag oily drips near the extract
- Tell us if menus or opening hours change
- Keep grease filters clean and fitted properly
- Keep to the recommended interval
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 you can produce them quickly.

Signs you need TR19 inspection in Heath End
Grease builds up as cooking vapour cools inside the extract. The thickest layers can sit out of sight in the plenum, at bends and along flat runs.
Any of these means the system needs a check-up:
- Kitchens taken over with no cleaning records
- Kitchens whose menu or hours have changed
- Parts of the system left out of past cleans
- Post-clean verification after another contractor’s clean
Healthcare kitchens, like those at hospitals such as Chiltern Hospital (about 5.2 miles south-west), often cook for long hours, which puts them in BESA’s heavier-use bands.

Why it’s worth doing now in Heath End
Sites in Heath End that have never measured grease can’t tell whether their cleaning interval suits the kitchen. Testing gives you the evidence to set it properly. Somewhere as small as Heath End, losing a kitchen or building to a fault is felt by everyone who uses it.
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.

What TR19 inspection looks like in Heath End
The FSA’s food hygiene register shows about 4 restaurants, cafés and works canteens across Heath End and its immediate surroundings (about a mile and a half). Kitchens like these cook for very different hours, and grease testing shows which extracts need cleaning soonest. Heath End is covered by 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. Environmental health officers from Dacorum council inspect food businesses in Heath End. 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.
For schools such as Hawridge and Cholesbury Church of England School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed. Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Cholesbury Manor House is about 1.3 miles west), access may need planning.

Fixed quotes for TR19 inspection in Heath End
There’s no set price list, because sites vary so much. The quote depends on:
- The number of sites or systems
- How easy every part is to reach
- The scale of the work
- Site requirements such as sign-in and permits
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered and we will price it together.
What we need to know
We can often survey from photos. The most useful are:
- When the site is open and when it’s quiet
- The postcode and the type of business
- How we’d reach plant on a roof or in a plant room
- Close-ups of filters, grilles, hatches or access panels
Quotes are quick. Send a few details and photos, and we usually reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
The process
Protection comes first: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. The work on site takes a couple of hours for a typical kitchen extract system, and we clear up before we go. For a village or hamlet like Heath End, tell us about narrow lanes, gates and parking when you book.
- First we book a time that will not disrupt cooking.
- The system is checked from canopy to discharge.
- Grease thickness is measured at set points by WFTT or DTT.
- Each test point and any access problems are photographed.
- The findings go into a report with readings, pictures and a recommended next clean.
Preparing for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Clear the space around the work
- Tell us about site rules, permits or sign-in
How to get a quote
For a fixed quote, call 0345 646 2711, or send details by email and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. You will typically have a quote within one working day.
Advice
When something else is needed
It’s worth knowing the limits before booking:
- Ductwork that was designed or installed badly
- Hidden runs that need access panels first
- Removing the grease, which is a separate clean
If you’re not sure, just call us on 0345 646 2711 or send us an email and we’ll give you a straight answer before you book.

Part by part
Extract fan and discharge
A greasy fan works harder and wears faster. The inspection shows whether it needs cleaning now.
Restaurants, pubs and hotels
BESA’s minimum for heavy use of 12 to 16 hours a day is a clean every 3 months, and readings show whether that is enough.
