When to call us in Middlegreen
Records can go missing when a business changes hands or contractors. With no history, the current state of the extract is a guess.
The symptoms we are asked about most are:
- An insurer’s request for a TR19 audit
- Kitchen extract systems with no recent grease readings
- Missing access panels found on survey
- Sites with gaps in their extract records
If you look after a school kitchen, at a school such as The Langley Academy Primary or anywhere near Middlegreen, the holidays are the usual time for a TR19® clean.
What your quote should include
- If they look at the system before pricing
- If the quote is a fixed price or an estimate
- Whether they recommend a next date
- Exactly which parts of the system are covered
TR19 inspection for kitchens and businesses in Middlegreen
Many insurers ask for proof that kitchen extract systems are cleaned and inspected to TR19®. Missing records can lead to a claim being reduced or refused. Our TR19 audits give sites in Middlegreen and across Slough a clear record of the system’s condition. If you’re dealing with extracts that may be over the 200 micron mean and checking the result of a recent clean, we can put it right, from insurer audits, deposit thickness tests and access surveys onwards.
In a small place like Middlegreen, 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.
Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

The process
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. The timing of a visit to Middlegreen is set by you, and the travel is our side of the planning.
- 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.
- We photograph each area to record how it was left.
- The results are reported, with anything missed flagged.
How to prepare
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Let us know about parking and loading
- Tell us about site rules, permits or sign-in
How to get a quote
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 work begins.
Advice
What TR19 inspection looks like in Middlegreen
The FSA’s food hygiene register shows about 49 cafés, restaurants and staff canteens and about 45 takeaways and sandwich shops within roughly a mile and a half of the centre of Middlegreen. For any of them with a canopy, measuring grease is better than guessing when to clean. In Middlegreen, food businesses are inspected by environmental health officers from Buckinghamshire council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Keeping each certificate and photo report on file helps show the extract is looked after. Fire safety in Middlegreen falls to Royal Berkshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
A kitchen near Langley station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval. Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Middlegreen is Upton Hospital, about 1.6 miles west.

What affects the cost of TR19 inspection
The diagnosis comes before the price. We look at:
- Whether it’s a one-off visit or part of a schedule
- Access, including roofs, risers and ceiling voids
- Site requirements such as sign-in and permits
- What state the system is in
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account, and the price is fixed before we start.
What we need to know
What to send for a quote:
- 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

What the work involves, part by part

Hospital and care home kitchens can cook all day, every day. Readings show if cleaning is frequent enough.

Leave it or put it right?
Finding a hotspot early means a targeted spot clean rather than a bigger problem later. Left alone, grease keeps building between cleans. In a small place like Middlegreen, a system that fails can take a site out of use.
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered, and you will get one fixed quote.

Questions from Middlegreen
Which fire service covers Middlegreen?
That is Royal Berkshire Fire and Rescue Service. 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.
Can you clean school kitchen extracts in Middlegreen during the holidays?
Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 13 schools, colleges and universities with registered kitchens within about a mile and a half of Middlegreen. Tell us your holiday dates and we will book the visit for when the site is empty.
What do you need from me for a quote?
The site address, the type of premises and your opening hours, plus pictures of the system and your last certificate or report if you have one.
What does a pre-clean survey involve?
A survey finds out how the system is laid out, how dirty it is and what can be reached, before anyone starts cleaning. Any access problems are flagged so they can be sorted first.
How much does TR19 inspection cost in Middlegreen?
Size, condition, access and working hours all affect the cost. Ask us for a fixed quote, normally ready within one working day.
What accreditations do you have?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
What does TR19 mean?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
What do the grease readings need to be?
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 your team can do, and what needs us
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We will take a look and send you a fixed quote.
