TR19 inspection for kitchens and businesses in Dial Post
BESA sets minimum cleaning intervals by daily use: every 3 months for heavy use of 12 to 16 hours a day, every 6 months for moderate use of 6 to 12 hours, and every 12 months for light use of 2 to 6 hours. Those are minimums, and grease readings help set the real interval. The work covers post-clean checks, access surveys and deposit thickness tests, and people most often call us about extracts that may be over the 200 micron mean and missing TR19 certificates or history.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. We agree access and timings in advance.
For insurers and inspectors, the record counts. That’s why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

When to call us in Dial Post
Grease is fuel. Flames from the range can be pulled into the canopy and travel through the ducts to other parts of the building. Measuring it is the first step to keeping it under control.
The symptoms we are asked about most are:
- Ductwork where grease may be over the TR19 limits
- Sites with gaps in their extract records
- Uncertainty over how often to clean
- Insurance renewals needing proof of TR19 cleaning
For a kitchen near Dial Post, the paperwork matters as much as the clean, so you get a certificate and pictures every time.
What your quote should include
- Proof of accreditation you can verify
- When the next visit should be, and why
- If they look at the system before pricing
- Whether the figure could change on the day
Fixed quotes for TR19 inspection in Dial Post
The survey tells us what the work involves. We look at:
- Where the site is and how we reach it
- The condition of the system
- When the work can happen, such as evenings, overnight or weekends
- How big the system is
Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you are unsure, call 0345 646 2711, or send details by email for straight advice and a fixed quote.
What to send for a quote
To speed up the quote, send us:
- Problems your staff have spotted
- Wide photos of the system and the area around it
- Your opening hours and when the area is out of use
- Close-ups of filters, grilles, hatches or access panels
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work, before any work starts.
What a clean won’t put right
It’s worth knowing the limits before booking:
- The responsible person’s own fire risk assessment
- The grease itself, which needs a full or spot clean
- Design faults in the extract system
Not sure which it is? You can give us a ring on 0345 646 2711, or email photos and we’ll tell you honestly.
Parts of the system we cover

We cover Dial Post, about 39 miles from central London, as part of our work across London and the South East. Visits are booked around your hours, evenings and weekends included.

Why act early in Dial Post
Without readings, you’re guessing when to clean. Any reading of 500 microns or more needs immediate spot cleaning under TR19® Grease, and you can only act on that if you’ve measured it. Out of sight is the usual reason a rural system goes too long without attention.
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we’ll go through it with you.

The process
We start by comparing what we find with the survey or your photos. If anything is different, we talk it through with the person on site before carrying on. From there, it takes around an hour or two per canopy and duct system. A few pictures of the system help us make the most of a visit to a place like Dial Post.
- Post-clean verification is booked once the clean is done.
- The same access points are opened up.
- Grease readings are taken again at set points.
- Photos are taken to show the condition after the clean.
- We report the findings and flag any areas that need more work.
How to prepare
- Dig out any earlier paperwork for the system
- Let us know about permits to work or site inductions
- Mention any locked doors, roof access or ceiling voids
How to get a quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.

Common questions in Dial Post
Who inspects food businesses in Dial Post?
In Dial Post, it’s Horsham council that carries out food hygiene inspections. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Which fire authority looks after Dial Post?
West Sussex Fire and Rescue Service is the fire and rescue service for Dial Post. 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 much does TR19 inspection cost?
Size, condition, access and working hours all affect the cost. Ask us for a fixed quote and we will normally reply within one working day.
Do you offer maintenance contracts?
Yes. Tell us what you have and how it’s used and we’ll propose a schedule with a fixed quote.
How often should grease be tested?
Enough to be sure grease stays within the TR19® Grease figures between cleans. If readings rise, the interval should shorten.
What does TR19 mean?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Do you cover Dial Post?
Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, and that includes Dial Post.
How do you keep the site clean during the work?
Floors and surfaces near the work are sheeted before we start, and waste is contained as we go. Before we leave, we tidy up and clean down.
What your team can do, and what needs us
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
How the job changes from site to site
Schools, hospitals and care homes
Education kitchens need TR19 inspections like any other. Readings show if the interval is right.
Vertical risers
In buildings with several floors, the riser may pass through other tenants’ space, so we arrange access ahead of time.
