Keeping the system healthy
Once we have finished, these simple steps help:

- Keep grease filters clean and fitted properly

You get a report with the grease readings, where they were taken and pictures of each point. Keep it with your fire safety and TR19 records.
Revisit the cleaning interval whenever the menu or hours change. Fresh readings show whether it needs to change.
TR19 inspection for kitchens and businesses in Clayhill
TR19® Grease says grease should not exceed a mean of 200 microns between cleans, and 500 microns or more at any point needs immediate spot cleaning. Grease testing shows which side of those lines you’re on. Common call-outs are for missing TR19 certificates or history and extracts that have never been grease tested, on insurer audits, post-clean checks and access surveys.
Work in a small place like Clayhill starts with a call to agree access and timings, and the clean itself is the same full TR19® job as in any town: canopy to discharge, then a TR19® certificate and a photo report.
Good records are part of the job. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

Honest limits
We won’t sell you work that doesn’t address the problem, so here are the limits:
- Heavy deposits found on test, which still need cleaning
- Fire safety duties beyond the extract system
- A faulty or failing extract fan
If you’re not sure, just give us a ring on 0345 646 2711, or email photos and we’ll give you a straight answer.

What we do, step by step
Your staff don’t need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. Somewhere as small as Clayhill, the date and timings are agreed with you well before the day.
- We go through any past certificates and reports.
- The layout is traced from the canopy to the discharge.
- Access panels are located and any missing ones noted.
- Grease readings are taken and pictures recorded.
- You get a report and a fixed quote for the clean.
Before we arrive
- Have your last certificate or report to hand
- Make sure equipment near the work can be switched off and left to cool
- Agree a time when the area can be out of use
How to get a quote
Here’s what helps us quote: the address, the type of site and when it’s open, a few pictures and the last certificate or report, if there is one. Once you have those, phone us on 0345 646 2711 or email us.

Landlords, agents and facilities managers
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.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
What affects the cost of TR19 inspection
The survey tells us what the work involves. We look at:
- Access, including roofs, risers and ceiling voids
- What state the system is in
- Working hours and out-of-hours timing
- How many systems or sites are involved
What you pay reflects the actual work. That’s why every job is surveyed first, and the price is agreed before we start.
Asking for a quote
Photos and a few facts are often enough to price the work. Send what you can of the following:
- The paperwork from the last visit, if you have it
- Detail shots of panels, filters and grilles
- The postcode and the type of business
- A few general shots of the system
For TR19 inspection in Clayhill, call 0345 646 2711, or send details by email. Let us know the site type and the opening hours, and send photos or your last report if you can. We typically send a fixed quote within one working day.
Different parts, different methods
Extract fan and discharge
Grease builds up on the fan blades and inside the housing. We check and test them as part of the inspection.
Vertical risers
Risers carry the extract up through the building. Grease can run down and collect at the base, so we check there.
What we are called out for in Clayhill
Menus, opening hours and cooking styles change over time, and more frying or longer hours mean more grease. The old cleaning schedule may not match the kitchen any more.
Any of these means the system needs a check-up:
- Pre-clean surveys before a first TR19 clean
- Systems cleaned on a calendar with no measurements
- Extracts that may be over the 200 micron mean
- Cleaning intervals that may not suit the kitchen
A hospital like Wycombe Hospital, about 2.3 miles north-east, is the kind of site where a kitchen may cook for patients, staff and visitors all day.
What your quote should include
- Whether the work can be done while the site is closed
- When the next visit should be, and why
- Whether a survey comes first
- Whether VAT is included
Common questions in Clayhill
Which fire and rescue service is responsible for Clayhill?
Fire safety enforcement in Clayhill is handled by Buckinghamshire Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Will you come out to Clayhill?
Yes. Clayhill is within the area we cover across London and the South East. A survey first, from photos or a visit, means we arrive with the right kit.
What is post-clean verification?
Verification means repeat readings and photos once the clean is done. Any areas that weren’t cleaned properly are flagged.
Can one contract cover all our sites?
Yes. Our area covers London and the South East, so we can schedule a run of sites on one programme. Each site gets its own report and pictures.
What’s 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 is not law, but it’s the benchmark.
How much does TR19 inspection cost?
We don’t publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before we start.
What is grease thickness testing?
The Wet Film Thickness Test (WFTT) and Deposit Thickness Test (DTT) measure how thick the grease is at a given point. Readings are taken at set points through the system.
How much notice do you need?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
Kitchen extracts in Clayhill
Look up Clayhill on the FSA’s food hygiene register and you will find about 18 cafés, restaurants and staff canteens and about 9 takeaways across Clayhill and its immediate surroundings (about a mile and a half). A WFTT or DTT reading tells each of those kitchens whether its grease is staying under the 200-micron mean. Clayhill sits within the area of Buckinghamshire Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. It’s Buckinghamshire council that sends environmental health officers to food businesses in Clayhill. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Our report lists what was cleaned and when, which is useful to have ready.
If you run a church or community hall kitchen, near Church of Christ the Servant King or elsewhere in Clayhill, its extract still collects grease from every lunch and event. If you run catering at a historic house or estate in the area (West Wycombe Park House is about 2.3 miles north), event kitchens in older buildings often have awkward duct runs that need planning.
