St John's TR19 inspection
We cover St John's for TR19 inspections, grease thickness testing, pre-clean surveys and post-clean verification. Fixed quotes, work around your opening hours and photo reports on every job.
- Ductwork where grease may be over the TR19 limits
- Systems cleaned on a calendar with no measurements
- Confirming a clean reached the whole system
Why act early in St John's
An EHO visit, an insurance renewal or a fire risk assessment is a bad time to find your extract records are thin. An inspection now gives a site in St John's a current picture. A quieter site near St John's still needs its system looked after.
The price reflects the work, not guesswork. That’s why every job is surveyed first, and why the quote is fixed before work begins.

TR19 inspection in St John's, done properly
Under TR19® Grease, the mean grease thickness should stay at or below 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 are on. The work covers access surveys, pre-clean surveys and wet film thickness tests, and the jobs we see most are missing access panels found on survey and systems cleaned on a calendar with no measurements.
Kitchens around a place like St John's are often in older buildings or single-storey extensions, with the duct running through a roof space or up an outside wall. Flat runs collect grease and need proper access to clean.
The paperwork matters as much as the work. Each visit is written up with pictures, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Aftercare tips
Here’s the after-treatment advice, in brief:
- Keep canopy edges and gutters wiped down
- Mention new equipment or longer hours at the next test
- Share inspection reports with your insurer or broker when asked
- Keep to the recommended interval
After the inspection, we send a report showing each reading, its location and pictures. Keep it with your fire safety and TR19 records.
Revisit the cleaning interval whenever the menu or hours change. A quick grease test answers the question.
How the job changes from site to site
Canopy and plenum
Behind the filters, the plenum catches plenty of grease. Readings and photos are taken in the plenum as part of every survey.
Vertical risers
Risers can be hard to get into. The survey shows exactly what access there is.
What affects the cost of TR19 inspection
Sites vary more than people expect. What affects the quote:
- A single visit or a regular plan
- How easy every part is to reach
- The number of sites or systems
- Working hours and out-of-hours timing
The cost depends on the size of the system, what state it’s in and how easy it is to reach. You get a fixed price before we start, so there are no surprises.
Helping us quote
Before you ask for a quote, gather:
- Your opening hours and when the area is out of use
- Your last certificate, test record or report
- The site address and the type of premises
- Close-ups of filters, grilles, hatches or access panels
There’s no standard price list, because no two systems are the same. We look at your system first, from pictures or on a visit, and then send you a fixed quote. To start, call 0345 646 2711, or email photos.
What staff can safely do
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
Kitchen extracts in St John's
The FSA’s food hygiene register shows about 34 restaurants, cafés and canteens and about 19 sandwich bars and takeaways within roughly a mile and a half of the centre of St John's. Each kitchen extract among them can be measured for grease to set the right cleaning interval. It’s Woking council that sends environmental health officers to food businesses in St John's. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Before-and-after pictures from each clean are a simple way to show the extract is in hand. Fire safety in St John's falls to Surrey 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.
If you run a church or community hall kitchen, near St John's Church or elsewhere in St John's, its extract still collects grease from every lunch and event. Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to St John's is Brookwood Hospital, about 1 mile west. For schools such as The Winston Churchill School A Specialist Sports College, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed.

Your questions about TR19 inspection in St John's
Will you come out to St John's?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
Who would carry out a food hygiene inspection at a kitchen in St John's?
That’s Woking council, whose environmental health officers carry out food hygiene inspections in St John's. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Is TR19 a legal requirement?
No. TR19® is BESA’s specification and the industry benchmark, not legislation. The law is the Fire Safety Order 2005, under which the responsible person must manage fire risk, and insurers, fire officers and EHOs look to TR19® as the benchmark.
Which kinds of sites do you work on?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
What do you do with what you remove?
It’s contained and taken away. We collect grease, debris and waste water as we go, so it does not spread.
What if parts of the system cannot be reached?
They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, along with a quote to put access in.
Do you carry out TR19 audits for insurers?
Yes, for kitchens across the South East and London. Tell us what your insurer has asked for and we’ll set the report out to match.
Can you come out in an emergency?
Yes. Our emergency line runs 24/7, for problems that can’t wait. Call us any time and explain what’s happened.
