Kitchen extracts in Great Gaddesden
Food Standards Agency records include about 3 bars, pubs and nightclubs in Great Gaddesden and the streets around it, up to about 1.5 miles out. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Kitchens in Great Gaddesden get their food hygiene inspections from Dacorum council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Hertfordshire Fire and Rescue Service covers Great Gaddesden. 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 Great Gaddesden Church of England Primary School tend to book extract cleaning for when the kitchen is empty. If you run a church or community hall kitchen, near Church of St John the Baptist or elsewhere in Great Gaddesden, its extract still collects grease from every lunch and event.

How we handle TR19 inspection in Great Gaddesden
Taking on a kitchen in Great Gaddesden with no cleaning records? Start with an inspection. You get readings, photos and a clear view of what’s needed, so the next step is based on facts. If you’re dealing with insurers asking for TR19 evidence and heavy grease suspected in the plenum or ducts, we can put it right, from access surveys, wet film thickness tests and post-clean checks onwards.
In a village or hamlet like Great Gaddesden, the kitchens that need extract cleaning are normally a pub, a school, a care home or a hall kitchen, wherever there is one. Every one of them still needs its extract kept clear of grease, whatever the size of the place.
For insurers and inspectors, the record counts. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

FAQs for Great Gaddesden
Can the work in Great Gaddesden be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. That way a site in Great Gaddesden does not have to lose a day’s trading. Let us know the hours you are closed and we’ll book within them.
Do you work in villages like Great Gaddesden?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
How do you protect the area?
With sheeting and covers, before anything else happens. The work is kept contained and clean down when we finish.
At what point does grease need cleaning?
TR19® Grease says the mean shouldn’t exceed 200 microns between cleans, and anywhere at 500 microns or more needs spot cleaning straight away.
What do you need from me for a quote?
Only a few details: the address, the site type, your opening hours and how we reach the system. Photos and any previous paperwork make it quicker. After that, simply call 0345 646 2711, or email photos.
Is TR19 cleaning the law?
No. TR19® is not law; it’s BESA’s specification. The legal duty comes from the Regulatory Reform (Fire Safety) Order 2005, which requires the responsible person to reduce fire risk, and TR19® is what insurers and fire officers look to.
What happens to the waste?
We take it away when we go. While we work, it’s kept contained to keep the area clean.
What is TR19?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t legislation, but it’s the standard people check against.
Honest limits
A few issues sit outside what this work can do:
- Mechanical faults in the extract
- Parts of the duct nobody can reach yet
- The grease itself, which needs a full or spot clean
If you’re not sure, just give us a ring on 0345 646 2711 or drop us a line and we will give you a straight answer before you book.

What affects the cost of TR19 inspection
A fixed price needs a few facts first. We check:
- Access, including roofs, risers and ceiling voids
- Where the site is and how we reach it
- How big the system is
- How many systems or sites are involved
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you’re unsure, call 0345 646 2711 or drop us a line and we’ll give you an honest view and a fixed quote.
Helping us quote
There’s no need for technical detail. Just send:
- The postcode and the type of business
- Photos showing the whole system and its surroundings
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Any previous report or certificate
Need a price for TR19 inspection? Please phone us on 0345 646 2711 or email us with a few details about the site. We will talk you through the work and send you a fixed quote before you commit to anything.
Looking after it afterwards
Aftercare is simple, and it makes the next visit easier:
- Book the next test on the date in the report
- Mention new equipment or longer hours at the next test
- Flag oily drips near the extract
- File every inspection report with your certificates
For an insurer audit, send them the report as it is, including readings, photos and any inaccessible sections.
When cooking hours or the menu change, check the interval still fits. A quick grease test answers the question.

In-house cleaning or a specialist?
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
What happens on the day
Your trading hours come first. 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 around an hour or two per canopy and duct system. A few pictures of the system help us make the most of a visit to a place like Great Gaddesden.
- Post-clean verification is booked once the clean is done.
- The same access points are opened up.
- Grease readings are taken again at set points.
- We photograph each area to record how it was left.
- The results are reported, with anything missed flagged.
Before we arrive
- Tell us where we can park and unload
- Tell us the best time to work, such as after service or at a weekend

When to call us in Great Gaddesden
As hot, greasy air travels up the duct, it cools and leaves a film behind. The thickest layers can sit out of sight in the plenum, at bends and along flat runs.
These are the problems we see most often:
- Uncertainty over how often to clean
- Missing TR19 certificates or history
- Pre-clean surveys before a first TR19 clean
- Parts of the system left out of past cleans
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 Great Gaddesden, about 3.2 miles south-east.
