TR19 inspections and grease testing in High Leigh, Hertfordshire
We cover High Leigh for TR19 inspections and grease testing. Fixed quotes, work around your opening hours and photo reports as standard.
- Post-clean verification after another contractor’s clean
- Insurance renewals needing proof of TR19 cleaning
- Cleaning intervals that may not suit the kitchen
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.
Restaurants, pubs and hotels
We test between services, early in the morning or after close so trading isn’t affected.
How we handle TR19 inspection in High Leigh
If you’ve taken over a kitchen in High Leigh and don’t know when the extract was last cleaned, an inspection is the place to start. We survey the system, measure the grease and tell you what needs doing, before any cleaning is booked. We are often asked to deal with an insurer’s request for a TR19 audit and kitchen extract systems with no recent grease readings, across post-clean checks, pre-clean surveys and access surveys.
In a small place like High Leigh, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. We agree access and timings in advance.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

High Leigh: your questions answered
Who would carry out a food hygiene inspection at a kitchen in High Leigh?
Food hygiene inspections in High Leigh are carried out by Broxbourne council. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Do you work in villages like High Leigh?
Yes. Villages and rural sites across the South East are part of our work, High Leigh included. A survey first, from photos or a visit, means we arrive with the right kit.
Do you offer maintenance contracts?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.
Which sectors do you work in?
All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.
Can you look after several sites?
Yes. You deal with one contact for every site in our area, with visits on a regular schedule.
How long does grease testing take?
It takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. The visit is timed so cooking is not disrupted.
Can you price the work without visiting?
In many cases, yes. With good photos, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
How do you protect the area?
By covering it before any work starts. The work is kept contained and clean down when we finish.
Kitchen extracts in High Leigh
According to Food Standards Agency records, there are about 15 pubs and bars within roughly a mile and a half of the centre of High Leigh. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. High Leigh sits within the area of Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. In High Leigh, food businesses are inspected by environmental health officers from Broxbourne council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
For schools such as Westfield Community Primary School, kitchen extract cleaning is typically booked for the holidays, when the canteen is closed. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Hertford County Hospital is the nearest hospital to High Leigh, about 3.5 miles north-west. Volunteers running a hall kitchen near Church of St Catherine & St Paul, or anywhere in High Leigh, may not know when the extract was last cleaned, and a grease test settles it.

What staff can safely do
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
Honest limits
An honest diagnosis matters more to us than a booking, so here’s what TR19 inspection won’t do:
- The responsible person’s own fire risk assessment
- A faulty or failing extract fan
- Sections with no access, until panels are fitted
If in doubt, call us on 0345 646 2711 or email us and we’ll say what we think before booking.
Where we work
- Insurer audits
- Access surveys
- Pre-clean surveys
- Post-clean checks
- Deposit thickness tests

Looking after it afterwards
To keep the system working properly between visits:
- Never cook with filters missing
- Book the next test on the date in the report
- Report grease dripping from the canopy
- Tell us if menus or opening hours change
After the inspection, we send a report showing each reading, its location and photos. Keep it with your fire safety and TR19 records.
Regular grease readings keep the cleaning interval honest. It shows if build-up is speeding up.
What we do, step by step
Your staff don’t need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. Photos of the system and how to reach it help us plan a visit to High Leigh.
- We go through any past certificates and reports.
- 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.
- You get a report and a fixed quote for the clean.
Getting ready for the visit
- Make sure someone can let us in and lock up afterwards
- Clear the space around the work
- Allow time for equipment near the work to be turned off and cool down
How to get a quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before we start.

How we price TR19 inspection
We don’t publish a price list, because no two systems are the same. What we look at:
- The size of the system
- One-off work versus a regular cycle
- When the work can happen, such as evenings, overnight or weekends
- Site rules, permits and inductions
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. You will have a fixed price before we start.
What we need to know
Photos let us diagnose from a distance. The most useful are:
- When the site is open and when it’s quiet
- The roof, plant room or outside wall the system runs to
- Any access panels or hatches you can see
- A few general shots of the system
Need a price for TR19 inspection? Please ring 0345 646 2711, or send details by email and tell us about the site. We’ll explain what we’d do and send a fixed quote before anything is booked.
What happens if it’s left?
Do not wait for an EHO visit or insurance renewal to find gaps in your extract records. An inspection now gives a site in High Leigh a current picture. Equipment tucked in a roof space or outbuilding near High Leigh rarely gets looked at unless someone books it.
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.
Why us?
- Out-of-hours work and a 24/7 emergency line
- We are fully insured
- We diagnose before we treat
- Accredited under CHAS and SafeContractor, with ISO 9001
