About our TR19 inspection in Blacknest
After a clean, post-clean verification checks the result, with new readings and photos of the cleaned areas. It gives you evidence of how the system was actually left. The work covers deposit thickness tests, insurer audits and wet film thickness tests, and the jobs we see most are kitchens whose menu or hours have changed and parts of the system left out of past cleans.
For a kitchen in or near Blacknest, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.
A written report with photos follows every visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Grease, kitchens and Blacknest
In Blacknest, food businesses are inspected by environmental health officers from East Hampshire council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Keeping each certificate and photo report on file helps show the extract is looked after. We cover Blacknest, about 40 miles from central London, as part of our work across London and the South East. We work evenings, overnight and at weekends, so the visit fits around the site.
Historic houses near Blacknest, such as Farnham Castle about 4.1 miles north-east, are a reminder that older buildings with event kitchens can have long, awkward duct routes. If you cook for passing trade around Bentley (Hampshire) station, the extract can be cleaned between your last and first customer.
Blacknest is about 4 miles south-west of Farnham, in Hampshire. Whatever kind of site you run in Blacknest, we can take on TR19 inspection. Visits can be booked for evenings, overnight or weekends so trading is not interrupted. We cover 683 places across Hampshire, large and small. Guildford is in our area too, around 14 miles away.

Keeping the system healthy
Aftercare is simple, and it makes the next visit easier:
- Share inspection reports with your insurer or broker when asked
- Mention new equipment or longer hours at the next test
- Keep the route to access panels clear
- Book the next test on the date in the report
The audit report is set out to pass straight to your insurer or broker, with readings, pictures and any areas not accessible.
Close the access gaps found during inspection, so every part of the duct can be cleaned.

The process
The first job on site is protection: floors, worktops and anything near the work are covered. Then we make the system safe and start. It takes anything from an hour for a small canopy and short duct to a good part of a day for a large site, and we clear up before we go. Rural roads and tight entrances are worth telling us about before a visit to Blacknest.
- The visit is arranged for when the kitchen is not busy.
- We look over the canopy, plenum, ducts, fan and discharge.
- Grease readings are taken at set points using WFTT or DTT.
- We photograph the test points and record any sections we cannot reach.
- The findings go into a report with readings, pictures and a recommended next clean.
Getting ready for the visit
- Have your last certificate or report to hand
- Clear the space around the work
- Make sure equipment near the work can be switched off and left to cool

Advice
When something else is needed
Before booking, it helps to know what’s not included:
- Hidden runs that need access panels first
- Ductwork that was designed or installed badly
- Mechanical faults in the extract
If in doubt, call 0345 646 2711, or send details by email and we’ll say what we think.
Where we work
- Access surveys
- Insurer audits
- Deposit thickness tests
- Wet film thickness tests
- Pre-clean surveys
- Post-clean checks
What happens if it’s left?
Skipping grease testing leaves the cleaning interval to guesswork. If grease reaches 500 microns anywhere, TR19® Grease calls for immediate spot cleaning, which you won’t know without measuring. Somewhere as small as Blacknest, losing a kitchen or building to a fault is felt by everyone who uses it.
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, give us a ring on 0345 646 2711 or use the quote form and we will give you an honest view and a fixed quote.

For landlords and multi-site operators
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
We also work for facilities teams across offices, schools and healthcare in Blacknest and across Hampshire. Work can be phased by floor, building or site around the people who use them.
In-house cleaning or a specialist?
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
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, alongside our reports.
FAQs for Blacknest
Do you work at weekends in Blacknest?
Yes, nights and weekends are routine for us. Your customers, staff or residents in Blacknest needn’t be disturbed. Just call 0345 646 2711, or send details by email with your opening times and we’ll plan around them.
Which fire service covers Blacknest?
It’s Hampshire and Isle of Wight Fire and Rescue Service, which covers Blacknest. TR19® is not law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
How far ahead should we book?
Earlier is better, particularly for night and weekend visits. We typically quote within one working day, and emergencies are covered by our 24/7 line.
What happens on a pre-clean survey?
We look at the system from canopy to discharge, take grease readings and check access. It lets us plan the clean and send you a fixed quote.
What should I send you?
The site address, the type of premises and your opening hours, plus photos of the system and your last certificate or report if you have one.
What is TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t legislation, but it’s the standard people check against.
Can one contract cover all our sites?
Yes. We work across South East England and London, so sites at different addresses can be planned together on one programme. Every site has its own report.
How much does TR19 inspection cost?
Size, condition, access and working hours all affect the cost. Call for a fixed quote and we will normally reply within one working day.
Do you need TR19 inspection in Blacknest?
Menus, opening hours and cooking styles change over time, and more frying or longer hours mean more grease. A cleaning interval set years ago may no longer fit.
It’s time to book a visit if you see:
- Extracts that have never been grease tested
- Insurance renewals needing proof of TR19 cleaning
- Sections of duct that can’t be reached
- Sites with gaps in their extract records
If you run catering at a healthcare site, such as a hospital like Chase Community Hospital about 4.7 miles south, the extract may need cleaning more often than a part-time kitchen.
