TR19 inspection in Merrow, done properly
Not every kitchen fits neatly into a calendar. Some kitchens build up grease faster than the minimum intervals assume, which is why measurement matters. We give your risk assessment measured figures rather than guesses. The work covers pre-clean surveys, wet film thickness tests and post-clean checks, and the jobs we see most are extracts that have never been grease tested and uncertainty over how often to clean.
In a smaller place like Merrow, the kitchens with extract systems are more likely to be a pub, a café, a takeaway or a school or care home kitchen than a big restaurant. Quieter kitchens still collect grease in the duct, just more slowly, so cleaning is planned around how much it cooks and what the readings show.
The sign-off is always in writing: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Aftercare tips
Good habits slow the build-up between visits. Our tips:
- Have the latest report ready for insurance renewals
- Store grease readings where your insurer can see them
- Keep to the recommended interval
- Tell us if menus or opening hours change
Each report suggests the next clean and the next test, from the measured grease and the kitchen’s hours.
Test grease regularly instead of relying on the calendar. It shows if build-up is speeding up.
Common questions in Merrow
Which fire and rescue service is responsible for Merrow?
That is 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.
Can you clean school kitchen extracts in Merrow during the holidays?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 12 schools, colleges and universities with registered kitchens within about a mile and a half of Merrow. Just phone us on 0345 646 2711 or use the quote form with your term dates and we’ll plan around them.
What grease levels does TR19 allow?
TR19® Grease says grease should not go over a mean of 200 microns between cleans. Any reading of 500 microns or more needs immediate spot cleaning.
Can you price the work without visiting?
Often, yes. With good pictures, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
Do you work out of hours?
Yes, and that is how we prefer to work. The visit is timed for when the area isn’t in use, whether that is late evening, overnight or a weekend.
Do you offer maintenance contracts?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
Do you cover Merrow?
Yes. Our technicians work in Merrow, as part of our area across London and the South East.
Can one contract cover all our sites?
Yes. One number covers all your sites in our area, with visits on a regular schedule.

Honest limits
In fairness, there are a few things this work won’t fix:
- Heavy deposits found on test, which still need cleaning
- Fan breakdowns, which need a repair visit
- Sections with no access, until panels are fitted
If you are not sure, just call 0345 646 2711 or email us and we will give you a straight answer before you book.

Merrow kitchens: local notes
The FSA’s data shows about 8 bars, pubs and nightclubs registered within roughly a mile and a half of the centre of Merrow. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Merrow sits within the area of 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. It’s Guildford council that sends environmental health officers to food businesses in Merrow. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Keeping each certificate and photo report on file helps show the extract is looked after.
For schools such as Bushy Hill Junior School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed. If you run catering at a historic house or estate in the area (Clandon Park is about 0.9 miles east), event kitchens in older buildings often have awkward duct runs that need planning. Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Merrow is St. Luke’s Hospital, about 1.5 miles south-west.
Merrow is about 2 miles east of Guildford, in Surrey. Whether your site is in the middle of Merrow or further out, TR19 inspection is available to all kinds of commercial premises, from small sites to large estates. Merrow is one of 395 places in Surrey we cover for commercial clients.

Leave it or put it right?
Surveying first means the clean goes to plan. Missing access panels, hidden duct runs and awkward fans are found before the cleaners arrive, so the clean covers the whole system. Booking now means the visit to Merrow is planned around you, not forced by a breakdown.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll explain each part.
Why book with us
- Full insurance on every job
- We diagnose before we treat
- Out-of-hours work and a 24/7 emergency line
- Fixed quotes from a survey or pictures
What happens on the day
There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with photos. The middle part takes longest, which takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. Evenings, weekends or a closed day all work for a site in a place like Merrow.
- After the clean, we arrange a time to check the system.
- We open the access points used on the clean.
- Grease readings are taken again at set points.
- Photos are taken to show the condition after the clean.
- The results are reported, with anything missed flagged.
Before we arrive
- Allow time for equipment near the work to be turned off and cool down
- Make sure someone can let us in and lock up afterwards
- Dig out any earlier paperwork for the system
Getting a quote
Every quote begins with a look at the system, from your photos and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work so you know the cost before any work starts.
Related advice
What affects the cost of TR19 inspection
The price is fixed before any work begins. It’s based on:
- Whether several sites go on one quote
- Working hours and out-of-hours timing
- Site requirements such as sign-in and permits
- Access, including roofs, risers and ceiling voids
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you are unsure, phone us on 0345 646 2711, or email photos and we will give you an honest view and a fixed quote.
What to send for a quote
Photos let us diagnose from a distance. The most useful are:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- When the site is open and when it’s quiet
- Where the site is and what kind of site it is
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
We do not publish a price list, because no two systems are the same. We look at your system first, from pictures or on a visit, then send a fixed quote. To get going, phone us on 0345 646 2711, or send details by email.
How the job changes from site to site
Vertical risers
Access to risers is often limited. We record what can and can’t be reached.
Extract fan and discharge
The extract fan and its housing collect grease too. They’re included in the readings and photos.
Multi-site and managed buildings
We regularly work with managing agents. Send the address, what’s needed and how access works, and we’ll send a fixed quote.
If you look after several sites, we can plan visits across the whole estate and price them together. Every building has its own written report, so each one has its own record.
