TR19 kitchen extract cleaning in Fields End
For kitchen extract cleaning in Fields End, one call is all it takes, from survey to sign-off. CHAS and SafeContractor accredited, ISO 9001 and fully insured.

In-house cleaning or a specialist?
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Kitchen duct cleaning in Fields End
A kitchen extract system is far more than the canopy you can see. Behind it sit the plenum and grease filters, then the ductwork, risers, extract fan and discharge, and grease settles in every one of them. Our clean follows the air from canopy to discharge, cleaning to BESA TR19® Grease. If you are dealing with grease dripping from the canopy or filters and an overdue clean flagged by an EHO or fire officer, we can help, from extract fans, plenums and filters and vertical risers onwards. Hood cleaning is where most enquiries from Fields End start: a clean that goes past the canopy into the duct and fan, backed by a certificate.
A kitchen running fryers and chargrills all day builds up grease much faster than one that mostly steams and boils, so we look at the menu as well as the opening hours when we suggest the next date.
Work in a small place like Fields End starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
Good records are part of the job. You get a written report with pictures after every visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Grease, kitchens and Fields End
Food Standards Agency records include about 17 pubs and bars across Fields End and its immediate surroundings (about a mile and a half). Any of them serving cooked food has an extract to keep clean, from canopy to discharge. In Fields End, food businesses are inspected by environmental health officers from Dacorum council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A dated certificate in the maintenance file answers the question before it’s asked. Fields End sits within the area of 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.
Bursars and site managers at schools such as John F Kennedy Catholic School tend to book extract cleaning for when the kitchen is empty. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Hemel Hempstead Hospital is the nearest hospital to Fields End, about 1.9 miles south-east.

Fields End questions
Which fire authority looks after Fields End?
Fire safety enforcement in Fields 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.
Do you clean school canteen extracts around Fields End out of term?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 12 schools, colleges and universities with registered kitchens within about a mile and a half of Fields End. Booking early in the term gives the best choice of holiday dates.
Will the clean disrupt our service?
The clean is done when the kitchen isn’t cooking, so evenings, overnight, early mornings and weekends are all options. Equipment needs to be off and cool before we start.
How far ahead should we book?
For planned work, earlier is better, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
Can you quote from pictures?
Often, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Where we cannot see enough, we arrange a survey.
What should I send you?
A short description and a few photos plus the address and your hours. We will ask for anything else we need.
Do you survey before quoting?
Yes. Every job is surveyed first, from your photos and details, or with a visit where needed. A fixed quote follows.
How often should a kitchen extract be cleaned?
BESA guidance sets minimums by daily cooking hours: every 3 months for 12 to 16 hours, 6 months for 6 to 12 hours and 12 months for 2 to 6 hours. Measured grease levels set the real interval.
For landlords and multi-site operators
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we’re happy to quote for all of it.
When it’s something else
We’d rather tell you now than book work that will not help, so these are the things it will not cover:
- A broken extract fan that won’t run
- A damper that sticks or has a damaged link
- Fat blocking the kitchen drains
If you’re not sure, just call 0345 646 2711, or email photos and we’ll give you a straight answer.

How the job changes from site to site
Extract fan and discharge
At the end of the system is the discharge, which can collect grease and stain the surface around it. It’s cleaned as far as safe access allows, and any limits are recorded.
Canopy and plenum
Canopies vary from a single hood to long runs over several appliances, every section is cleaned and recorded in the photo report before and after.
What happens on the day
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes anything from a few hours to a full night, depending on the size of the system. For a village or hamlet like Fields End, tell us about narrow lanes, gates and parking when you book.
- Diagnosis comes first, with a survey of the system and how it’s reached.
- We record grease levels at set points, then fix the price.
- We arrive after close, protect the area and contain the waste.
- Heavy deposits are scraped by hand and the system degreased to TR19® Grease.
- Then the clean bill of health: readings, a TR19 certificate and a photo report with the next date.
Preparing for the visit
- Arrange a key holder or contact on site
- Dig out any earlier paperwork for the system
- Tell us where we can park and unload
Ask for a quote
To help us quote: where the site is, what it is and its opening hours, pictures of the system and the last certificate or report, if there is one. Once you have those, give us a ring on 0345 646 2711 or send us an email.

Signs you need kitchen extract cleaning in Fields End
A lot of duct grease gets there because the filters let it through. Filters that are bent, badly fitted, missing or left uncleaned let more fat into the plenum and duct, and it does not stop until it reaches the fan.
Common reasons sites call us include:
- A kitchen taken over without any extract records
- An inspection that picked up a dirty extract
- A kitchen with no current TR19 certificate
- Rancid smells from grease in the duct
A hall kitchen that only cooks for events, whether near St Alban's Church or elsewhere in Fields End, still needs its extract cleaned, just less often.
Before booking anyone

Leave it or put it right?
There’s no law that names TR19, but the Fire Safety Order 2005 still applies. The responsible person must assess and reduce fire risk, which in a kitchen includes the grease in the extract. TR19 is the benchmark insurers, fire officers and EHOs look to. With notice, the visit to Fields End can be fitted around your bookings and events.
