TR19 inspection for kitchens and businesses in Garston
A fixed schedule does not always match how a kitchen really cooks. Some kitchens build up grease faster than the minimum intervals assume, and only measurement shows it. We give your risk assessment measured figures rather than guesses. If you have missing TR19 certificates or history and ductwork where grease may be over the TR19 limits, we can help, from wet film thickness tests, post-clean checks and deposit thickness tests onwards.
For a smaller kitchen near Garston, a TR19® clean is the same job as anywhere: canopy, filters, plenum, duct, fan and discharge. The visit is booked around your opening hours, and the journey is planned ahead.
Every visit ends with a written report and pictures, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What affects the cost of TR19 inspection
The survey tells us what the work involves. We look at:
- How many systems or sites are involved
- Travel, parking and unloading
- Site rules, permits and inductions
- Access, including roofs, risers and ceiling voids
We do not list prices on the website, because each job is priced on what it involves. Call for a fixed quote, and we will talk you through it.
Asking for a quote
To speed up the quote, please include:
- The site address and the type of premises
- Your last certificate, test record or report
- Any symptoms, from odd noises to smells or leaks
- How we’d reach plant on a roof or in a plant room
Getting a quote does not take long. Send a few details and pictures, and we normally reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
Garston: your questions answered
Do you work overnight in Garston?
Yes, out-of-hours work is a big part of what we do. The work in Garston can fit around your hours. Your opening times are the first thing we ask for.
Is Garston within the area you cover?
Yes, we work in villages as well as towns, and Garston is covered. Just mention lanes, gates or anything else about the site when you book.
How much does TR19 inspection cost?
It depends on the site, so we quote each one individually. For a quote, call us on 0345 646 2711, or send details by email and tell us about the site and its opening hours.
Can you verify a clean after it’s been done?
After a clean, we take new readings and pictures to show how the system was left. It works whoever carried out the clean.
Do you have a 24/7 line?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
How long does a TR19 inspection take?
As a guide, it takes a couple of hours for a typical kitchen extract system. The size of the system and the access make the difference.
Can you quote from pictures?
Yes, where the pictures show enough. If not, a site survey comes first, then a fixed quote.
Do you look at the system first?
Yes. We always survey first, from your photos and details, or with a visit where needed. Then you get a fixed quote.
Honest limits
Before booking, it helps to know what’s not included:
- Hidden runs that need access panels first
- Removing the grease, which is a separate clean
- Fan breakdowns, which need a repair visit
Not sure which it is? You can phone us on 0345 646 2711, or send details by email and we’ll tell you honestly before you book.
Where we work
- Deposit thickness tests
- Post-clean checks
- Insurer audits
- Wet film thickness tests
- Pre-clean surveys
- Access surveys
What your team can do, and what needs us
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Looking after it afterwards
A little care between visits keeps the system in better shape. We recommend:
- Keep canopy edges and gutters wiped down
- Mention new equipment or longer hours at the next test
- Keep access panels clear and unpainted
- Have the latest report ready for insurance renewals
The report recommends when the system should next be cleaned and tested, 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.
What happens on the day
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. All told, the work takes around an hour or two per canopy and duct system. Tell us about any gates, ladders or locked plant areas at your site near Garston when you book.
- After the clean, we arrange a time to check the system.
- The same access points are opened up.
- We repeat the WFTT or DTT readings.
- Photos are taken to show the condition after the clean.
- The results are reported, with anything missed flagged.
Getting ready for the visit
- Find the previous report, if there is one
- Tell us the best time to work, such as after service or at a weekend
- Make sure someone can let us in and lock up afterwards

Signs you need TR19 inspection in Garston
Menus, opening hours and cooking styles change over time, and more frying or longer hours mean more grease. The old cleaning schedule may not match the kitchen any more.
What we are most often called out for:
- Insurers asking for TR19 evidence
- Ductwork where grease may be over the TR19 limits
- Kitchen extract systems with no recent grease readings
- Kitchens taken over with no cleaning records
A hospital like Leavesden Hospital, about 1.4 miles north-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day.
Before booking anyone
- How areas they can’t reach will be recorded
- Whether they’re fully insured
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether the whole system is included, or only the parts that are easy to reach
Multi-site and managed buildings
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.
