TR19 inspection in Great Bookham, done properly
If you’ve taken over a kitchen in Great Bookham and don’t know when the extract was last cleaned, an inspection is the place to start. We survey the system, measure the grease and tell you what needs doing, before any cleaning is booked. Common call-outs are for extracts that have never been grease tested and parts of the system left out of past cleans, across insurer audits, post-clean checks and pre-clean surveys.
Around a smaller place like Great Bookham, kitchen extracts tend to belong to pubs, cafés, takeaways and school or care home kitchens. A kitchen that cooks fewer hours still builds up grease, so the interval is set by hours of use and grease readings.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, 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.

Fixed quotes for TR19 inspection in Great Bookham
The diagnosis comes before the price. We look at:
- Site requirements such as sign-in and permits
- Parking and loading at the site
- A single visit or a regular plan
- How many systems or sites are involved
What you pay reflects the actual work. That is why we survey first, from photos or on site, and why the quote is fixed before we start.
Helping us quote
Before you ask for a quote, gather:
- When the site is open and when it’s quiet
- Problems your staff have spotted
- The postcode and the type of business
- How we’d reach plant on a roof or in a plant room
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
How it works
Protection comes first: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. It takes around an hour or two per canopy and duct system, and we clear up before we go. Because the survey comes first, a visit to Great Bookham can usually be finished without a second trip.
- The visit is arranged for when the kitchen isn’t busy.
- Every part of the system is examined, end to end.
- We take WFTT or DTT readings at set points along the system.
- Photos are taken at each point, and access gaps noted.
- The findings go into a report with readings, photos and a recommended next clean.
Preparing for the visit
- Allow time for equipment near the work to be turned off and cool down
- Let us know how we reach the system, including roofs, risers and plant rooms
- Make sure someone can let us in and lock up afterwards
Ask for a quote
Getting a quote doesn’t take long. Send a few details and pictures, and we typically reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

Part by part
Vertical risers
Risers carry the extract up through the building. Grease can run down and collect at the base, so the base is a key test point.
Restaurants, pubs and hotels
We test between services, early in the morning or after close so the kitchen keeps cooking.
In-house cleaning or a specialist?
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
Keeping the system healthy
Looking after the system between visits is straightforward, and it helps at the next visit:
- Keep TR19 certificates, readings and reports together
- Keep the route to access panels clear
- Diary the next grease test and clean
- Flag oily drips near the extract
After the inspection, we send a report showing each reading, its location and pictures. Keep it with your fire safety and TR19 records.
Clean, correctly fitted filters stop more grease reaching the duct. Missing or damaged filters let grease straight into the plenum.
Why deal with it now?
Post-clean verification shows whether the system was left the way the certificate says, before the next clean is due. Around Great Bookham, a kitchen or building out of action is missed straight away.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re unsure, call 0345 646 2711, or send details by email and we’ll give you an honest view and a fixed quote.

Great Bookham kitchens: local notes
The FSA’s food hygiene register includes about 5 pubs, bars and clubs within about 1.5 miles of central Great Bookham. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Kitchens in Great Bookham get their food hygiene inspections from Mole Valley council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A dated certificate in the maintenance file answers the question before it’s asked. Surrey Fire and Rescue Service covers Great Bookham. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
If you run catering at a healthcare site, such as a hospital like Headley Court about 4.1 miles east, the extract may need cleaning more often than a part-time kitchen. School kitchens, at schools like The Dawnay School for example, are typically cleaned in the holidays so no lunches are lost.
