TR19 inspection in Aston
If you’ve taken over a kitchen in Aston and don’t know when the extract was last cleaned, an inspection is the place to start. You get readings, pictures and a clear view of what’s needed, so the next step is based on facts. If you have systems cleaned on a calendar with no measurements and pre-clean surveys before a first TR19 clean, we can put it right.
For a kitchen in or near Aston, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Grease, kitchens and Aston
The fire and rescue service for Aston is Oxfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Environmental health officers from West Oxfordshire council inspect food businesses in Aston. Extraction counts as kitchen equipment, so its condition can come up on the day. Keeping each certificate and photo report on file helps show the extract is looked after.
If you run catering at a healthcare site, such as a hospital like Longworth Hospital about 5.7 miles south-west, the extract may need cleaning more often than a part-time kitchen. Longworth House, about 3.4 miles south-east, is one of the historic houses near Aston; if you run event catering at a venue like that, cleans can be booked between functions.
Aston is about 4 miles south of Witney, in Oxfordshire. Every kind of commercial site in Aston, TR19 inspection is something we can help with. We can work out of hours so trading is not interrupted.

Aftercare tips
After the visit, a few habits help the work last:
- Keep to the recommended interval
- Clean grease off the canopy between professional cleans
- Send TR19 audit reports to your insurer on request
- Keep grease filters clean and fitted properly
The audit report is set out to pass straight to your insurer or broker, including readings, photos and any inaccessible sections.
Keep filters clean and in place. Gaps around filters let grease get past them.
Part by part
Restaurants, pubs and hotels
Kitchens that cook for long hours build up grease faster. Regular testing shows whether the cleaning interval keeps up.
Extract fan and discharge
Grease builds up on the fan blades and inside the housing. We check and test them as part of the inspection.
What we do, step by step
There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with pictures. The middle part takes longest, which takes a morning or less for one kitchen, more where there are several systems. In a small place like Aston, the journey is planned ahead and the visit arranged around the site’s hours.
- After the clean, we arrange a time to check the system.
- We open the access points used on the clean.
- 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.
Before we arrive
- Clear loose items from the work area
- Arrange a key holder or contact on site
- Agree a time when the area can be out of use
Getting a quote
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.
Related advice
Staff cleaning versus specialist work
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
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. With notice, the visit to Aston can be fitted around your bookings and events.
Working hours, access and the scale of the site all affect the cost. We take each of them into account and give you a fixed price before we start.

Landlords, agents and facilities managers
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
We also work for facilities teams across offices, schools and healthcare across Oxfordshire. Work can be phased by floor, building or site to keep disruption down.
What we are called out for in Aston
Menus, opening hours and cooking styles change over time, and more frying or longer hours mean more grease. A cleaning interval set years ago may no longer fit.
Most sites get in touch when they notice something like this:
- Ductwork where grease may be over the TR19 limits
- Sections of duct that can’t be reached
- Kitchens taken over with no cleaning records
- Checking the result of a recent clean
For schools such as Aston and Cote Church of England Primary School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.

Aston: your questions answered
Do you do school kitchen extract cleaning in Aston in the summer holidays?
Yes, and it’s the easiest time to do it. The FSA’s register shows about 2 schools and colleges with food registrations within roughly a mile and a half of Aston. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Who would carry out a food hygiene inspection at a kitchen in Aston?
Food hygiene inspections in Aston are carried out by West Oxfordshire council. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
What grease levels does TR19 allow?
Under TR19® Grease, the mean thickness should not exceed 200 microns between cleans. Any reading of 500 microns or more needs immediate spot cleaning.
What is a WFTT or DTT grease test?
The Wet Film Thickness Test (WFTT) and Deposit Thickness Test (DTT) measure how thick the grease is at a given point. We take readings at set points from canopy to fan.
Do you offer maintenance contracts?
Yes. Send details of the systems and how they’re used and we’ll propose a schedule with a fixed quote.
Is TR19 a legal requirement?
No. TR19® is BESA’s specification and the industry benchmark, not legislation. The law is the Fire Safety Order 2005, under which the responsible person must manage fire risk, and TR19® is what insurers and fire officers look to.
What does TR19 inspection cost?
Every site is different, so each gets its own fixed quote. For a quote, phone us on 0345 646 2711 or send us an email and tell us about the site and its opening hours.
Will you produce a report for our insurer?
Yes, anywhere in the area we cover. Share the insurer’s request so the report addresses it.
