Grease, kitchens and Mindenhurst
According to Food Standards Agency records, there are about 5 bars, pubs and nightclubs within roughly a mile and a half of the centre of Mindenhurst. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. In Mindenhurst, food businesses are inspected by environmental health officers from Surrey Heath council. Extraction counts as kitchen equipment, so its condition can come up on the day. Our report lists what was cleaned and when, which is useful to have ready. Mindenhurst is covered by Surrey Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Frimley Park Hospital is the nearest hospital to Mindenhurst, about 2.1 miles north-west.

TR19 inspection in Mindenhurst, done properly
BESA sets minimum cleaning intervals by daily use: heavy use (12 to 16 hours a day) every 3 months, moderate use (6 to 12 hours) every 6 months and light use (2 to 6 hours) every 12 months. Those are minimums, and grease readings help set the real interval. If you have sections of duct that can’t be reached and insurance renewals needing proof of TR19 cleaning, we can put it right, from deposit thickness tests, access surveys and insurer audits onwards.
Somewhere as small as Mindenhurst, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Each still has a canopy and duct that collect grease.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

What we’re called out for in Mindenhurst
Kitchens change: a new menu, longer hours or more frying can all add grease. A cleaning interval set years ago may no longer fit.
Common reasons sites call us are:
- Uncertainty over how often to clean
- Insurers asking for TR19 evidence
- Systems that need surveying before cleaning
- Post-clean verification after another contractor’s clean
Term dates shape school work: for a school like Sandringham Infant & Nursery School, an extract clean fits neatly into a half-term or summer break.
Before you book anyone
- When the next visit should be, and why
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether the figure could change on the day
- How areas they cannot reach will be recorded
What TR19 inspection can’t fix
We will not sell you work that does not address the problem, so here are the limits:
- Sections with no access, until panels are fitted
- Design faults in the extract system
- Mechanical faults in the extract
If you’re not sure, just phone us on 0345 646 2711 or send us an email and we’ll give you a straight answer.
Where we work
- Pre-clean surveys
- Access surveys
- Insurer audits
- Wet film thickness tests
- Deposit thickness tests
- Post-clean checks
What the work involves, part by part
Horizontal duct runs
Flat duct runs collect grease along their base. Readings are taken along each run through its access panels.
Extract fan and discharge
Grease on the fan adds to wear. Readings show if it needs attention before the next clean.
FAQs for Mindenhurst
Can school kitchens in Mindenhurst be cleaned in the holidays?
Yes, holiday work suits schools best. There are about 7 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Mindenhurst. You can give us a ring on 0345 646 2711 or send us an email with the dates the site is empty.
Can you come to Mindenhurst after we close?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Mindenhurst needn’t be disturbed. Let us know the hours you are closed and we will book within them.
What does TR19 mean?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
What do you do to protect the area?
With sheeting and covers, before anything else happens. We keep the work contained and leave the area clean.
What do the grease readings need to be?
The TR19® Grease figures are a mean of 200 microns or less between cleans, and immediate spot cleaning wherever a reading hits 500 microns. We show your readings against those figures.
What is post-clean verification?
Verification means repeat readings and pictures once the clean is done. The report flags anything missed.
Is a quote from pictures possible?
In many cases, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Larger or hidden systems need a survey on site first.
Which sectors do you work in?
All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.

Why deal with it now?
Sites in Mindenhurst that have never measured grease cannot tell whether their cleaning interval suits the kitchen. Testing gives you the evidence to set it properly. In a small place like Mindenhurst, a system that fails can take a site out of use.
The price reflects the work, not guesswork. That’s why every job is surveyed first, and why the quote is fixed before any work starts.

What your team can do, and what needs us
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
What affects the quote in Mindenhurst
We do not publish a price list, because no two systems are the same. What we look at:
- Travel, parking and unloading
- Site rules, permits and inductions
- Whether we need access equipment or extra panels
- When the work can happen, such as evenings, overnight or weekends
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at, and you’ll get one fixed quote.
What we need to know
We can often survey from pictures. Try to include:
- The site address and the type of premises
- Your last certificate, test record or report
- A few general shots of the system
- Close-ups of filters, grilles, hatches or access panels
For a fixed quote, give us a ring on 0345 646 2711, or email photos with the site type, your trading hours and a short description of the system. A few pictures and your last certificate or report help a lot. You will usually have a quote within one working day.
What happens on the day
Every visit runs to the same pattern: protect the area, isolate whatever needs isolating, carry out the TR19 inspection, tidy up and leave you the report. On site, the work takes an hour or two for a single kitchen, longer for a large or complex system. Somewhere like Mindenhurst, lanes, gates and parking are worth mentioning in advance.
- 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.
- We photograph the test points and record any sections we cannot reach.
- You get a report with readings, pictures and recommendations.
Before we arrive
- Let us know how we reach the system, including roofs, risers and plant rooms
- Move anything stored near the system
- Mention any sign-in, permit or induction we need
Ask for a quote
Some systems can be priced from photos; others need a survey. 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.
