Schools, hospitals and care homes
We fit testing around service times and school holidays to avoid disruption.
How we handle TR19 inspection in Dedworth
Before any clean in Dedworth, we survey the canopy, plenum, filters, ducts, fan and discharge. Access is checked along the full length, and grease readings are taken at set points. Typical jobs include heavy grease suspected in the plenum or ducts and kitchens taken over with no cleaning records, on wet film thickness tests, post-clean checks and access surveys.
Around a smaller place like Dedworth, kitchen extracts tend to belong to pubs, cafés, takeaways and school or care home kitchens. Quieter kitchens still collect grease in the duct, just more slowly, so the interval is set by hours of use and grease readings.
The sign-off is always in writing: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

When it’s something else
We will not sell you work that doesn’t address the problem, so these are the things it won’t cover:
- The legal duty, which stays with the responsible person
- Ductwork that was designed or installed badly
- Sections with no access, until panels are fitted
If you’re not sure, just phone us on 0345 646 2711, or send details by email and we will give you a straight answer before booking.

Aftercare tips
Aftercare is simple, and it helps at the next visit:
- Book the next test on the date in the report
- Clean grease off the canopy between professional cleans
- Store grease readings where your insurer can see them
- Flag oily drips near the extract
You get a report with the grease readings, where they were taken and pictures of each point. File it alongside your TR19 certificates.
Revisit the cleaning interval whenever the menu or hours change. A quick grease test answers the question.
The process
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes a couple of hours for a typical kitchen extract system. Because the survey comes first, a visit to Dedworth can typically be finished without a second trip.
- After the clean, we arrange a time to check the system.
- We open the access points used on the clean.
- We repeat the WFTT or DTT readings.
- We photograph each area to record how it was left.
- The results are reported, with anything missed flagged.
Preparing for the visit
- Allow time for equipment near the work to be turned off and cool down
- Let us know about parking and loading
- Move anything stored near the system

FAQs for Dedworth
Can you clean school kitchen extracts in Dedworth during the holidays?
Yes. Half-terms and the summer break are the natural time for school work. Around Dedworth, the Food Standards Agency lists about 23 schools and colleges with registered kitchens within a mile and a half or so. Send us your term dates when you give us a ring on 0345 646 2711 or send us an email, and we will fit the work in.
Who inspects food businesses in Dedworth?
In Dedworth, it’s Windsor and Maidenhead 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.
What is grease thickness testing?
Readings are taken using the Wet Film Thickness Test or the Deposit Thickness Test, and set against the TR19® Grease figures.
What happens if you cannot reach some of it?
Anything we can’t reach goes on the report, with a note of where it is, and we tell you what would make it reachable, for example new access panels.
How often should grease be tested?
Often enough to know the mean stays under 200 microns between cleans. The readings themselves tell you if the interval needs to change.
Do you work with multi-site operators?
Yes. One number covers all your sites across London and the South East, with visits on a regular schedule.
Can you set up regular visits?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.
Do you survey before quoting?
Yes, every time. We diagnose before we treat: the survey shows what needs doing and what access we need, and the quote is based on that.
Multi-site and managed buildings
From a single site to a large estate, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We are happy to deal with either side, and the report can go to both.
Why deal with it now?
If a kitchen in Dedworth has been cleaned on the same calendar for years, there’s no way to know if that interval is right without measuring. Testing gives you the evidence to set it properly. You choose the date of a planned visit, and a breakdown never asks.
Every site is different, 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.

What TR19 inspection looks like in Dedworth
The FSA’s food hygiene register shows about 120 cafés, restaurants and staff canteens and about 18 sandwich bars and takeaways in Dedworth and the streets around it, up to about 1.5 miles out. A WFTT or DTT reading tells each of those kitchens whether its grease is staying under the 200-micron mean. Fire safety in Dedworth falls to Royal Berkshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. It’s Windsor and Maidenhead council that sends environmental health officers to food businesses in Dedworth. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A dated certificate in the maintenance file answers the question before it’s asked.
If you run catering at a historic house or estate in the area (St Leonard's Hill is about 0.6 miles south), event kitchens in older buildings often have awkward duct runs that need planning. Volunteers running a hall kitchen near All Saints Church, or anywhere in Dedworth, may not know when the extract was last cleaned, and a grease test settles it. Bursars and site managers at schools such as Dedworth Green First School tend to book extract cleaning for when the kitchen is empty.

What staff can safely do
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
