TR19 inspection in Holwellbury
If you’ve taken over a kitchen in Holwellbury 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. If you’re dealing with confirming a clean reached the whole system and ductwork where grease may be over the TR19 limits, we can help.
Somewhere as small as Holwellbury, 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.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

Honest limits
An honest diagnosis matters more to us than a booking, so here’s what TR19 inspection will not do:
- The legal duty, which stays with the responsible person
- Fan breakdowns, which need a repair visit
- Installation problems, which fall under design guidance such as DW172
If in doubt, call 0345 646 2711, or send details by email and we’ll say what we think before booking.

Your questions about TR19 inspection in Holwellbury
Who inspects food businesses in Holwellbury?
The local authority for Holwellbury is Central Bedfordshire council, and its environmental health team does the inspecting. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Which fire service covers Holwellbury?
It’s Hertfordshire Fire and Rescue Service, which covers Holwellbury. TR19® isn’t law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Which kinds of sites do you work on?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
What should I send you?
The site address, the type of premises and your opening hours, along with a few pictures and any previous report.
What does a pre-clean survey involve?
We survey, measure and photograph the system first. The survey can be done from photos and details or on site, whichever suits the system.
How far ahead should we book?
For planned work, earlier is better, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.
Do you work with multi-site operators?
Yes. Our area covers London and the South East, so we can schedule a run of sites as one programme. Each site gets its own report and pictures.
Is Holwellbury in your area?
Yes. We work in Holwellbury and the rest of Hertfordshire, as part of our work across South East England and London. To book, call 0345 646 2711 or email us.
Aftercare tips
Good habits slow the build-up between visits. A few tips:
- Keep access panels clear and unpainted
- Clean or swap grease filters as often as the kitchen needs
- Send TR19 audit reports to your insurer on request
- Tell us if menus or opening hours change
After post-clean verification, file the results with the cleaning certificate. The pair gives a clear record of the clean and the check.
Clean, correctly fitted filters stop more grease reaching the duct. Gaps around filters let grease get past them.
How we price TR19 inspection
Every site gets its own quote. This is what makes a difference:
- The condition we find in the survey
- The size of the system
- Travel, parking and unloading
- Whether several sites go on one quote
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.
Helping us quote
We can often survey from photos. Try to include:
- The roof, plant room or outside wall the system runs to
- Any symptoms, from odd noises to smells or leaks
- A few general shots of the system
- Your last certificate, test record or report
Getting a quote does not take long. Send a few details and photos, and we typically reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
Signs you need TR19 inspection in Holwellbury
Grease in a duct is flammable fuel. A flare-up on the range can be drawn into the canopy and duct, and from there a fire can spread through the ductwork. Measuring it is the first step to keeping it under control.
It’s time to book a visit if you see:
- Insurers asking for TR19 evidence
- Cleaning intervals that may not suit the kitchen
- Extracts that may be over the 200 micron mean
- Confirming a clean reached the whole system
If you run catering at a healthcare site, such as a hospital like Fairfield Hospital about 2.1 miles east, the extract may need cleaning more often than a part-time kitchen.
Questions to ask before booking
- If they look at the system before pricing
- What records you will receive afterwards
- Whether they’re fully insured
- Whether VAT is included
Staff cleaning versus specialist work
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
What TR19 inspection looks like in Holwellbury
Look up Holwellbury on the FSA’s food hygiene register and you will find about 3 cafés, restaurants and staff canteens and about 8 takeaways and sandwich shops within about 1.5 miles of central Holwellbury. Where they cook under a canopy, a grease reading is the way to tell whether the extract is due a clean. Fire safety in Holwellbury falls to Hertfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Food hygiene inspections in Holwellbury are the job of Central Bedfordshire council’s environmental health team. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Before-and-after photos from each clean are a simple way to show the extract is in hand.
If you run a church or community hall kitchen, near Church of St Peter (C of E) at Corner with Holwell Road or elsewhere in Holwellbury, its extract still collects grease from every lunch and event. School kitchens, at schools like Derwent Lower School for example, are typically cleaned in the holidays so no lunches are lost.

For landlords and multi-site operators
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.
Facilities teams in offices, schools and healthcare sites book us too across Hertfordshire. Work can be phased by floor, building or site to keep disruption down.
The process
We start by comparing what we find with the survey or your pictures. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes a couple of hours for a typical kitchen extract system. If the van will struggle with a lane or gateway near Holwellbury, let us know and we will plan around it.
- 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.
- You get a report and a fixed quote for the clean.
Getting ready for the visit
- Clear the space around the work
- Let us know about parking and loading
- Dig out any earlier paperwork for the system
Ask for a quote
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.
