How we handle TR19 inspection in Tower Hill
A fixed schedule doesn’t always match how a kitchen really cooks. In a busy kitchen, grease can build faster than the minimum intervals allow for, which is why measurement matters. Our readings give your risk assessment real numbers to work from. We are often asked to deal with pre-clean surveys before a first TR19 clean and insurers asking for TR19 evidence, on insurer audits, pre-clean surveys and deposit thickness tests.
Somewhere as small as Tower Hill, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Every one of them still needs its extract kept clear of grease, whatever the size of the place.
For insurers and inspectors, the record counts. That’s why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Kitchen extracts in Tower Hill
According to Food Standards Agency records, there are about 9 pubs and bars within roughly a mile and a half of the centre of Tower Hill. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. The fire and rescue service for Tower Hill is Hertfordshire 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. It’s Dacorum council that sends environmental health officers to food businesses in Tower Hill. Extraction counts as kitchen equipment, so its condition can come up on the day. Keeping each certificate and photo report on file helps show the extract is looked after.
Church and community hall kitchens, near Church of St Paul or anywhere around Tower Hill, are easy to forget, but their extracts collect grease like any other. If you run catering at a healthcare site, such as a hospital like Hemel Hempstead Hospital about 3.1 miles north-east, the extract may need cleaning more often than a part-time kitchen.
Tower Hill is about 3 miles south-west of Hemel Hempstead, in Hertfordshire.

Your questions about TR19 inspection in Tower Hill
Do you work overnight in Tower Hill?
Yes. We work evenings, overnight and at weekends. The work in Tower Hill can fit around your hours. Just give us a ring on 0345 646 2711 or send us an email with your opening times and we will plan around them.
Do you clean school canteen extracts around Tower Hill out of term?
Yes. Half-terms and the summer break are the natural time for school work. Around Tower Hill, the Food Standards Agency lists about 3 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we will book the visit for when the site is empty.
Can you verify a clean after it’s been done?
Verification means repeat readings and photos once the clean is done. The report flags anything missed.
How do you protect the area?
We cover floors and nearby surfaces with sheeting before we start, and waste is contained as we go. Before we leave, we tidy up and clean down.
Where does the waste go?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. We do not leave it behind.
Do you offer maintenance contracts?
Yes. Send details of the systems and how they’re used and we will propose a schedule with a fixed quote.
What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
How often should a kitchen extract be inspected?
We suggest a next test date in every report, based on the readings and how the kitchen is used. A risk assessment based on measured grease should set the interval.
Signs you need TR19 inspection in Tower Hill
Grease in a duct is flammable fuel. Flames from the range can be pulled into the canopy and travel through the ducts to other parts of the building. Knowing how much there is lets you act before it becomes a hazard.
These are the problems we see most often:
- Surveys needed before quoting a full clean
- Extracts that may be over the 200 micron mean
- Systems cleaned on a calendar with no measurements
- Post-clean verification after another contractor’s clean
If you look after a school kitchen, at a school such as Kings Langley School or anywhere near Tower Hill, the holidays are the usual time for a TR19® clean.
What your quote should include
- Whether the figure could change on the day
- Proof of insurance
- Which accreditations they hold, and whether you can check them
- Whether the quote shows VAT

What we do, step by step
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. The visit itself takes around an hour or two per canopy and duct system. Pictures of the system and its access let us plan the work in Tower Hill before we set off.
- First we look at the system’s cleaning history, if there is one.
- The layout is traced from the canopy to the discharge.
- We note where access panels are and where more are needed.
- We measure the grease and photograph each point.
- You get a report and a fixed quote for the clean.
Before we arrive
- Let us know about parking and loading
- Let us know when the site is closed or quiet
- Mention any locked doors, roof access or ceiling voids
How to get a quote
We don’t publish a price list, because every site is different. We look at your system first, from pictures or on a visit, then send a fixed quote. To start, call us on 0345 646 2711 or drop us a line.

Different parts, different methods
Vertical risers
Vertical risers take the extract up through the floors. Grease can drain down and pool at the bottom, so the base is a key test point.
Canopy and plenum
Filters can look fine while the plenum behind them is heavily coated. So we measure behind the filters, not just in front.
Fixed quotes for TR19 inspection in Tower Hill
The quote reflects the site in front of us. We take into account:
- Site requirements such as sign-in and permits
- What state the system is in
- Working hours and out-of-hours timing
- The size of the system
What you pay depends on the size of the system, the condition it’s in and access to every part of it. You get a fixed price before any work starts, so there are no surprises.
Asking for a quote
What to send for a quote:
- The times we could work without disrupting the site
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Any symptoms, from odd noises to smells or leaks
- Any previous report or certificate
Quotes are quick. Send a few details and photos, and we usually reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
Multi-site and managed buildings
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.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
Between visits
So the system stays in good health:
- Flag oily drips near the extract
- File every inspection report with your certificates
- Diary the next grease test and clean
- Have the latest report ready for insurance renewals
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.
Close the access gaps found during inspection, so every part of the duct can be cleaned.
