TR19 inspection for kitchens and businesses in Leatherhead
BESA sets minimum cleaning intervals by daily use: heavy use (12 to 16 hours a day) every 3 months, moderate use (6 to 12 hours) every 6 months and light use (2 to 6 hours) every 12 months. Grease testing shows whether your kitchen needs cleaning more often than that. If you are dealing with missing TR19 certificates or history and systems cleaned on a calendar with no measurements, we can help, from wet film thickness tests, access surveys and post-clean checks onwards.
Most kitchens in a town like Leatherhead can’t close for a day, so the work is done after service, overnight or on a closed day. By the next service, the kitchen is ready to cook in again.
For insurers and inspectors, the record counts. That is why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Different parts, different methods
Extract fan and discharge
The discharge at the end of the system is checked as well, as grease can build up there too.
Canopy and plenum
Clean-looking filters do not mean a clean plenum. So we measure behind the filters, not just in front.

Fixed quotes for TR19 inspection in Leatherhead
Before we fix a price, we need to know a few things. We look at:
- One-off work versus a regular cycle
- Parking and loading at the site
- The condition we find in the survey
- Site rules, permits and inductions
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, ring 0345 646 2711 or send us an email for straight advice and a fixed quote.
Helping us quote
Photos and a few facts are often enough to price the work. Useful things to send:
- Any symptoms, from odd noises to smells or leaks
- The times we could work without disrupting the site
- How we’d reach plant on a roof or in a plant room
- Photos showing the whole system and its surroundings
To help us quote: where the site is, what it is and its opening hours, a few photos and any previous report or certificate. Then call us on 0345 646 2711 or email us.
Questions from Leatherhead
Can you work in Leatherhead outside opening hours?
Yes, we can come after you close and finish before you open. It means the site in Leatherhead keeps running as normal. Tell us your opening hours when you ask for a quote.
Who enforces fire safety at workplaces in Leatherhead?
That’s Surrey Fire and Rescue Service. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
What grease levels does TR19 allow?
Two figures matter: a mean of no more than 200 microns between cleans, and 500 microns at any single point, which needs immediate spot cleaning. Our report sets your readings against both.
Can you verify a clean after it’s been done?
A post-clean check records grease readings and pictures after the work, whoever did the clean.
Is TR19 a legal requirement?
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.
How far ahead should we book?
That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
What is grease thickness testing?
It’s a measurement of how much grease is coating the inside of the extract, by WFTT or DTT. The results are given in microns.
How long does a TR19 inspection take?
An inspection takes a morning or less for one kitchen, more where there are several systems. Large or multiple systems take longer, so call 0345 646 2711 or send us an email and we will plan it.
What happens on the day
We are used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work takes a morning or less for one kitchen, more where there are several systems. Work in Leatherhead is usually booked after closing, early in the morning or on a closed day.
- We agree a time when the kitchen is closed or quiet.
- The system is checked from canopy to discharge.
- Grease thickness is measured at set points by WFTT or DTT.
- We photograph the test points and record any sections we cannot reach.
- The findings go into a report with readings, photos and a recommended next clean.
Getting ready for the visit
- Tell us about site rules, permits or sign-in
- Let us know how we reach the system, including roofs, risers and plant rooms
- Name a contact who can let us in at the agreed time
Getting a quote
There’s no standard price list, because every site is different. Instead, we look at your site first, from pictures or a survey, and then give you a fixed quote. To start, give us a ring on 0345 646 2711 or use the quote form.

What happens if it’s left?
Without readings, you are guessing when to clean. Any reading of 500 microns or more needs immediate spot cleaning under TR19® Grease, which you will not know without measuring. A small fault found now is a quick job; the same fault found later can close the site.
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll explain each part.

TR19 inspection in Leatherhead: the local picture
According to Food Standards Agency records, there are about 9 pubs and bars across Leatherhead and its immediate surroundings (about a mile and a half). Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Fire safety in Leatherhead falls to Surrey Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. Food hygiene inspections in Leatherhead are the job of Mole Valley council’s environmental health team. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Before-and-after pictures from each clean are a simple way to show the extract is in hand.
For kitchens close to Leatherhead station, where the day often starts early and ends late, the extract can be cleaned overnight. A hall kitchen that only cooks for events, whether near Church of Our Lady and St Peter or elsewhere in Leatherhead, still needs its extract cleaned, just less often.

What a clean will not put right
In fairness, some problems need a different fix:
- The responsible person’s own fire risk assessment
- Parts of the duct nobody can reach yet
- The grease itself, which needs a full or spot clean

For landlords and multi-site operators
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
Whether it’s one building or many, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Do you need TR19 inspection in Leatherhead?
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.
If you notice any of these, it’s worth a diagnosis:
- Kitchens whose menu or hours have changed
- Missing access panels found on survey
- Missing TR19 certificates or history
- Extracts that may be over the 200 micron mean
A hospital like Headley Court, about 2.2 miles east, is the kind of site where a kitchen may cook for patients, staff and visitors all day.
