TR19 inspection in Maplehurst, done properly
A pre-clean survey is the diagnosis, and the clean is the treatment. We look at the system, take grease readings and photograph what we find, so the clean can be planned properly. Typical jobs include kitchens taken over with no cleaning records and extracts that have never been grease tested, on post-clean checks, deposit thickness tests and access surveys.
In a small place like Maplehurst, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. We agree access and timings in advance.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

What TR19 inspection looks like in Maplehurst
About 35 miles out from central London, Maplehurst is part of the South East area we work across. Visits are booked around your hours, evenings and weekends included. Environmental health officers from Horsham council inspect food businesses in Maplehurst. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Keeping each certificate and photo report on file helps show the extract is looked after.
Healthcare kitchens, like those at hospitals such as Horsham Hospital (about 4.3 miles north), often cook for long hours, which puts them in BESA’s heavier-use bands. If you run a church or community hall kitchen, near The Parish Church of St Andrew or elsewhere in Maplehurst, its extract still collects grease from every lunch and event. If you look after a school kitchen, at a school such as St Andrew's CofE Primary School or anywhere near Maplehurst, the holidays are the usual time for a TR19® clean.

How the visit works
Each visit runs to the same pattern: sheeting and protection first, isolate whatever needs isolating, carry out the TR19 inspection, tidy up and leave you the report. On site, the work takes anything from an hour for a small canopy and short duct to a good part of a day for a large site.

- First we book a time that will not disrupt cooking.
- Every part of the system is examined, end to end.
- We take WFTT or DTT readings at set points along the system.

- You get a report with readings, pictures and recommendations.
Preparing for the visit
- Make sure someone can let us in and lock up afterwards
- Let us know about parking and loading

Fixed quotes for TR19 inspection in Maplehurst
Sites vary more than people expect. The main factors:
- Working hours and out-of-hours timing
- One-off work versus a regular cycle
- How easy every part is to reach
- Parking and loading at the site
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.
Helping us quote
Many jobs can be priced from photos and some basics. Send what you can of the following:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Your opening hours and when the area is out of use
- Detail shots of panels, filters and grilles
Getting a quote does not take long. Call or email with a few details and you’ll usually have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
Your questions about TR19 inspection in Maplehurst
Which fire authority looks after Maplehurst?
Fire safety enforcement in Maplehurst is handled by West Sussex Fire and Rescue Service. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Do you cover smaller places like Maplehurst?
Yes, Maplehurst is part of our area, however small the site. Just mention lanes, gates or anything else about the site when you book.
Can we book visits on a schedule?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
What is grease thickness testing?
The Wet Film Thickness Test (WFTT) and Deposit Thickness Test (DTT) measure how thick the grease is at a given point. We take readings at set points from canopy to fan.
Do you survey before quoting?
Yes. For many sites, pictures and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
Are you accredited?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We’re fully insured and have been trading since 2009.
How long does a TR19 inspection take?
Testing takes an hour or two for a single kitchen, longer for a large or complex system. Large or multiple systems take longer, and you can phone us on 0345 646 2711 or use the quote form to book it in.
Can you inspect our extract for our insurance company?
Yes. Insurers often want evidence the extract is managed to TR19®, and our audit gives a clear record of the system’s condition, along with any actions needed.

Aftercare tips
After the visit, a few habits help the work last:
- Keep the route to access panels clear
- Wipe the canopy surfaces regularly
- Look out for grease drips round the canopy edge
- Have the latest report ready for insurance renewals
For an insurer audit, send them the report as it is, with readings, pictures and any areas not accessible.
Close the access gaps found during inspection, so grease isn’t left building in hidden parts.
When it’s something else
We will always give you a straight diagnosis, so here’s what TR19 inspection won’t do:
- The responsible person’s own fire risk assessment
- Ductwork that was designed or installed badly
- Removing the grease, which is a separate clean
If you’re not sure, just give us a ring on 0345 646 2711 or email us and we’ll give you a straight answer.
Where we work
- Wet film thickness tests
- Pre-clean surveys
- Access surveys
- Insurer audits
- Deposit thickness tests
- Post-clean checks
What the work involves, part by part
Vertical risers
Vertical risers take the extract up through the floors. Grease can run down and collect at the base, so we check there.
Horizontal duct runs
If a run has no access panel, we note it so it can be fixed before the clean.
What staff can safely do
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
