Staff cleaning versus specialist work
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
TR19 inspection in Brill
Grease thickness testing tells you how much grease is sitting in the canopy, ducts and fan. Readings are taken at set points using the Wet Film Thickness Test (WFTT) or the Deposit Thickness Test (DTT). From the numbers, you can see whether cleaning is due. Typical jobs include ductwork where grease may be over the TR19 limits and pre-clean surveys before a first TR19 clean, across access surveys, insurer audits and deposit thickness tests.
In a small place like Brill, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.
We’ve been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Landlords, agents and facilities managers
Whether it’s one building or many, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with pictures.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
Between visits
Once we’ve finished, these simple steps help:
- Flag changes in how much frying the kitchen does
- Report grease dripping from the canopy
- Never cook with filters missing
- Send TR19 audit reports to your insurer on request
The audit report is set out to pass straight to your insurer or broker, including readings, photos and any inaccessible sections.
Fit access panels where the survey finds sections cannot be reached, so every part of the duct can be cleaned.
What happens on the day
Each visit runs to the same pattern: sheeting and protection first, make the system safe, do the work, clear away and leave you the report. The visit itself takes a couple of hours for a typical kitchen extract system. The timing of a visit to Brill is set by you, and the travel is our side of the planning.
- After the clean, we arrange a time to check the system.
- We open the access points used on the clean.
- We repeat the WFTT or DTT readings.
- We photograph each area to record how it was left.
- The results are reported, with anything missed flagged.
Getting ready for the visit
- Let us know about permits to work or site inductions
- Mention any parking or loading restrictions
- Tell us the best time to work, such as after service or at a weekend
Ask for a quote
There’s no standard price list, because every site is different. We look at your system first, from pictures or on a visit, and then give you a fixed quote. To get going, call 0345 646 2711, or email photos.

What happens if it’s left?
Skipping grease testing leaves the cleaning interval to guesswork. Any reading of 500 microns or more needs immediate spot cleaning under TR19® Grease, and you can only act on that if you’ve measured it. Equipment tucked in a roof space or outbuilding near Brill rarely gets looked at unless someone books it.
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at, and you’ll get one fixed quote.

How we price TR19 inspection
There’s no set price list, because no two systems are the same. What we look at:
- Whether it’s a one-off visit or part of a schedule
- When the work can happen, such as evenings, overnight or weekends
- Travel, parking and unloading
- The size of the system
What you pay depends on how big the system is, the condition it’s in and access to every part of it. You get a fixed price before work begins, so there are no surprises.
Asking for a quote
To help us quote quickly, send us:
- A few general shots of the system
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Close-ups of filters, grilles, hatches or access panels
- The site address and the type of premises
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before work begins.
TR19 inspection in Brill: the local picture
The Food Standards Agency lists about 3 pubs, bars and clubs as registered food businesses within about 1.5 miles of central Brill. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Kitchens in Brill get their food hygiene inspections from Buckinghamshire council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Our report lists what was cleaned and when, which is useful to have ready. Fire safety in Brill falls to Buckinghamshire 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 Brill Church of England School tend to book extract cleaning for when the kitchen is empty. Church and community hall kitchens, near United Reformed Church or anywhere around Brill, are easy to forget, but their extracts collect grease like any other.

Your questions about TR19 inspection in Brill
Can you get to a site in Brill?
Yes. Villages and rural sites across the South East are part of our work, Brill included. The journey is planned ahead, so a few details about the route help.
Which council inspects kitchens in Brill?
Kitchens in Brill are inspected by Buckinghamshire council’s environmental health officers. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
What do you do to protect the area?
We start with protection: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
Can you quote from pictures?
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 much notice should we give?
Earlier is better, particularly for night and weekend visits. Quotes typically come back within one working day, and emergencies are covered by our 24/7 line.
Which kinds of sites do you work on?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
Is there a survey before the work?
Yes. For many sites, pictures and a few details are enough, and larger or hidden systems get a visit.
Is TR19 cleaning the law?
No. TR19® is BESA’s specification and the industry benchmark, not legislation. 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.
Signs you need TR19 inspection in Brill
Records can go missing when a business changes hands or contractors. With no history, the current state of the extract is a guess.
Any of these means the system needs a check-up:
- Sections of duct that cannot be reached
- Missing TR19 certificates or history
- An insurer’s request for a TR19 audit
- Ductwork where grease may be over the TR19 limits
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Boarstall Tower is about 1.9 miles west), access may need planning.
