TR19 inspection in Three Ashes
Not every kitchen fits neatly into a calendar. In a busy kitchen, grease can build faster than the minimum intervals allow for, which is why measurement matters. Our readings give your risk assessment real numbers to work from. If you have extracts that may be over the 200 micron mean and systems cleaned on a calendar with no measurements, we can help.
In a small place like Three Ashes, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. We agree access and timings in advance.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

How the job changes from site to site
Horizontal duct runs
Bends and long runs can hold heavy deposits, well away from where anyone looks.
Restaurants, pubs and hotels
BESA’s minimum for heavy use of 12 to 16 hours a day is a clean every 3 months, with testing showing whether more is needed.
Aftercare tips
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Keep grease filters clean and fitted properly
- Have the latest report ready for insurance renewals
- Report grease dripping from the canopy
- Keep canopy edges and gutters wiped down
Any access problems we found are listed with a suggested fix. Fitting them before the next clean means the whole system gets done.
Clean, correctly fitted filters stop more grease reaching the duct. Missing or damaged filters let grease straight into the plenum.
Three Ashes: your questions answered
Which fire service covers Three Ashes?
That is Royal Berkshire 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.
Which environmental health team covers Three Ashes?
That’s Basingstoke and Deane council, whose environmental health officers carry out food hygiene inspections in Three Ashes. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
What happens to the waste?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. None of it is left on site.
At what point does grease need cleaning?
TR19® Grease says the mean shouldn’t exceed 200 microns between cleans, and anywhere at 500 microns or more needs spot cleaning right away.
What types of premises do you cover?
Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
What is TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
How much time does an inspection need?
It takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. The visit is timed so cooking isn’t disrupted.
What does TR19 inspection cost?
Every site is different, so each gets its own fixed quote. For a quote, call 0345 646 2711, or send details by email with the site type, opening hours and a few pictures.

TR19 inspection around Three Ashes
Food hygiene inspections in Three Ashes are the job of Basingstoke and Deane council’s environmental health team. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A dated certificate in the maintenance file answers the question before it’s asked. Fire safety in Three Ashes falls to Royal Berkshire Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (The Vyne is about 2.8 miles south), access may need planning. If you run a church or community hall kitchen, near Church of St. Mary or elsewhere in Three Ashes, its extract still collects grease from every lunch and event.

Leave it or put it right?
Sites in Three Ashes that have never measured grease cannot tell whether their cleaning interval suits the kitchen. Measured readings let a competent person set the interval. Systems in rural buildings are often out of sight and out of mind.

Fixed quotes for TR19 inspection in Three Ashes
The survey tells us what the work involves. The main factors are:
- Access, including roofs, risers and ceiling voids
- Travel, parking and unloading
- Site requirements such as sign-in and permits
- The condition we find in the survey
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.
Helping us quote
What to send for a quote:
- The times we could work without disrupting the site
- Close-ups of filters, grilles, hatches or access panels
- How we’d reach plant on a roof or in a plant room
- The paperwork from the last visit, if you have it
Quotes are quick. Call or email with a few details and you will typically have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
When to call us in Three Ashes
As hot, greasy air travels up the duct, it cools and leaves a film behind. It often collects where nobody can see it: the plenum, bends and horizontal runs.
Keep an eye out for these warning signs:
- Post-clean verification after another contractor’s clean
- Extracts that may be over the 200 micron mean
- Systems cleaned on a calendar with no measurements
- Insurance renewals needing proof of TR19 cleaning
If you run catering at a healthcare site, such as a hospital like Basingstoke and North Hampshire Hospital about 4.8 miles south, the extract may need cleaning more often than a part-time kitchen.
What your quote should include
- Whether the figure could change on the day
- Whether VAT is included
- Whether a survey comes first
- What insurance they carry
What we do, step by step
A visit follows the same order every time: sheeting and protection first, make the system safe, do the work, clear away and hand over the paperwork. On site, the work takes an hour or two for a single kitchen, longer for a large or complex system. A quick note on how to find the site and where to park makes a visit to Three Ashes run smoothly.
- 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.
- We photograph each area to record how it was left.
- We report the findings and flag any areas that need more work.
How to prepare
- Let us know how we reach the system, including roofs, risers and plant rooms
- Clear loose items from the work area
- Plan for cooking equipment or plant to be off before we arrive
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, you get a fixed price before any work starts.
