TR19 inspection in Blackwater
A fixed schedule doesn’t always match how a kitchen really cooks. Some kitchens build up grease faster than the minimum intervals assume, and only measurement shows it. Our readings give your risk assessment real numbers to work from. The work covers access surveys, deposit thickness tests and insurer audits, and the jobs we see most are heavy grease suspected in the plenum or ducts and systems cleaned on a calendar with no measurements.
In a village or hamlet like Blackwater, the kitchens that need extract cleaning are usually a pub, a school, a care home or a hall kitchen, wherever there is one. Every one of them still needs its extract kept clear of grease, whatever the size of the place.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Looking after it afterwards
How long the results last depends on use and care. We suggest:
- Send TR19 audit reports to your insurer on request
- Book the next test on the date in the report
- Flag oily drips near the extract
- Keep canopy edges and gutters wiped down
The report recommends when the system should next be cleaned and tested, based on the readings and how the kitchen is used.
Regular grease readings keep the cleaning interval honest. It spots changes in how fast grease builds.
Signs you need TR19 inspection in Blackwater
You can’t judge grease thickness by eye. Clean filters can hide a heavy layer behind them, so readings are the reliable guide.
The symptoms we’re asked about most include:
- Kitchen extract systems with no recent grease readings
- Uncertainty over how often to clean
- Heavy grease suspected in the plenum or ducts
- Missing TR19 certificates or history
Term dates shape school work: for a school like Christ The King College, an extract clean fits neatly into a half-term or summer break.
Before booking anyone
- Which accreditations they hold, and whether you can check them
- Whether the quote is based on a survey or pictures
- Exactly which parts of the system are covered
- What records you’ll receive afterwards
What affects the quote in Blackwater
You will get a fixed price before we start. It’s based on:
- Whether it’s a one-off visit or part of a schedule
- Parking and loading at the site
- The times the site is available
- The condition we find in the survey
What you pay depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before work begins, so you know where you stand.
What to send for a quote
We can often survey from photos. The most useful are:
- Photos showing the whole system and its surroundings
- Close-ups of filters, grilles, hatches or access panels
- The site address and the type of premises
- Any symptoms, from odd noises to smells or leaks
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.
What TR19 inspection looks like in Blackwater
The FSA’s data shows about 3 pubs, bars and clubs registered within 1.5 miles or so of the middle of Blackwater. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Environmental health officers from Isle of Wight council inspect food businesses in Blackwater. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Before-and-after photos from each clean are a simple way to show the extract is in hand. Hampshire and Isle of Wight Fire and Rescue Service covers Blackwater. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.
If you run a church or community hall kitchen, near St. Olave's Church or elsewhere in Blackwater, its extract still collects grease from every lunch and event. If you run catering at a historic house or estate in the area (Gatcombe House is about 1.2 miles south-west), event kitchens in older buildings often have awkward duct runs that need planning.
Blackwater is about 2 miles south of Newport, in the Isle of Wight. Every kind of commercial site in Blackwater, we can take on TR19 inspection.

Common questions in Blackwater
Who inspects food businesses in Blackwater?
That’s Isle of Wight council, whose environmental health officers carry out food hygiene inspections in Blackwater. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
Is Blackwater within the area you cover?
Yes, Blackwater is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
What if parts of the system can’t be reached?
They’re marked on the report. In ductwork, new access panels are often the answer, and we can fit those.
How much does TR19 inspection cost?
We do not publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. You get a fixed price before work begins.
What grease levels does TR19 allow?
TR19® Grease says the mean shouldn’t exceed 200 microns between cleans, with 500 microns or more anywhere needing immediate spot cleaning.
How often should a kitchen extract be inspected?
We suggest a next test date in every report, taking the readings and the kitchen’s hours into account. A risk assessment based on measured grease should set the interval.
What is a WFTT or DTT grease test?
Grease thickness testing measures the layer of grease on the duct surfaces, using the Wet Film Thickness Test (WFTT) or Deposit Thickness Test (DTT). Each reading is recorded in microns.
What accreditations do you have?
We hold CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
Landlords, agents and facilities managers
Whether it’s one building or many, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Facilities teams in offices, schools and healthcare sites book us too across the Isle of Wight. Larger estates can be phased building by building around the people who use them.
Part by part
Schools, hospitals and care homes
Hospital and care home kitchens can cook all day, every day. Testing shows if the cleaning interval keeps pace.
Vertical risers
Access to risers is often limited. The survey shows exactly what access there is.
What TR19 inspection can’t fix
We’d rather tell you now than book work that won’t help, so here are the limits:
- Design faults in the extract system
- Sections with no access, until panels are fitted
- Fan breakdowns, which need a repair visit
If in doubt, phone us on 0345 646 2711, or email photos and we will say what we think before booking.
Parts of the system we cover
- Access surveys
- Pre-clean surveys
- Insurer audits
- Post-clean checks
- Deposit thickness tests
- Wet film thickness tests

What happens on the day

- The layout is traced from the canopy to the discharge.
- We note where access panels are and where more are needed.
- Grease readings are taken and pictures recorded.
- You get a report and a fixed quote for the clean.
How to prepare

Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.
