TR19 inspections and grease testing in Oakley, Buckinghamshire
Need TR19 inspection in Oakley? We survey first, give you a fixed quote and work around your opening hours, then sign off with a report and pictures.

What happens if it’s left?
A pre-clean survey avoids surprises on the night. Missing access panels, hidden duct runs and awkward fans are found before the cleaners arrive, and the quote reflects the real job. Out of sight is the usual reason a rural system goes too long without attention.
The price reflects the work, not guesswork. That’s why we survey first, from pictures or on site, and the price is agreed before we start.

About our TR19 inspection in Oakley
BESA’s minimum cleaning frequencies depend on how long the kitchen cooks each day: 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. The work covers post-clean checks, wet film thickness tests and insurer audits, and common reasons people get in touch are confirming a clean reached the whole system and parts of the system left out of past cleans.
For a kitchen in or near Oakley, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
Every visit ends with a written report and pictures, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What staff can safely do
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 can diagnose it and quote.
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
What affects the cost of TR19 inspection
Every site gets its own quote. These are the things that affect it:
- The size of the system
- One-off work versus a regular cycle
- Site requirements such as sign-in and permits
- The number of sites or systems
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we will explain each part.
What to send for a quote
When you call or email, these details help:
- Any symptoms, from odd noises to smells or leaks
- Where the site is and what kind of site it is
- Photos showing the whole system and its surroundings
- The roof, plant room or outside wall the system runs to
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.
Managing agents and facilities teams in Oakley
Facilities teams in offices, schools and healthcare sites book us too in Oakley and across Buckinghamshire. Work can be phased by floor, building or site around the people who use them.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side and send the paperwork to whoever needs it.
The process
Every visit runs to the same pattern: sheeting and protection first, isolate whatever needs isolating, do the work, clear away and hand over the paperwork. On site, the work takes a morning or less for one kitchen, more where there are several systems. Visits to a village like Oakley are booked in advance, at a time that suits whoever runs the site.
- Post-clean verification is booked once the clean is done.
- The same access points are opened up.
- We repeat the WFTT or DTT readings.
- Photos are taken to show the condition after the clean.
- The results are reported, with anything missed flagged.
How to prepare
- Mention any sign-in, permit or induction we need
- Tell us where we can park and unload
- Mention any locked doors, roof access or ceiling voids
Getting a quote
There’s no standard price list, because every site is different. We look at your system first, from photos or on a visit, then send a fixed quote. To start, phone us on 0345 646 2711, or send details by email.

What the work involves, part by part
Schools, hospitals and care homes
School and college kitchens still need their extract checked. Testing shows whether the interval suits.
Vertical risers
In buildings with several floors, the riser may pass through other tenants’ space, so we arrange access ahead of time.

What TR19 inspection looks like in Oakley
The FSA’s data shows about 3 pubs and bars registered within about 1.5 miles of central Oakley. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Oakley sits within the area of Buckinghamshire 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. Food hygiene inspections in Oakley are the job of Buckinghamshire council’s environmental health team. 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.
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Boarstall Tower is about 1.5 miles north-west), access may need planning. A hall kitchen that only cooks for events, whether near Church of St Mary or elsewhere in Oakley, still needs its extract cleaned, just less often. Term dates shape school work: for a school like Oakley Church of England Combined School, an extract clean fits neatly into a half-term or summer break.

Questions from Oakley
Which fire authority looks after Oakley?
Fire safety enforcement in Oakley is handled by Buckinghamshire 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.
Do you do school kitchen extract cleaning in Oakley in the summer holidays?
Yes. The holidays are the usual time for school work. Around Oakley, the Food Standards Agency lists about 3 schools and colleges with registered kitchens within a mile and a half or so. You can ring 0345 646 2711 or email us with the dates the site is empty.
Do you have a 24/7 line?
Yes. Our emergency line runs 24/7, for problems that can’t wait. Call us any time and explain what’s happened.
What if parts of the system cannot be reached?
The report shows them clearly. In ductwork, new access panels are often the answer, and we can fit those.
Do you offer maintenance contracts?
Yes. Tell us what you have and how it’s used, and we’ll suggest a schedule and quote for it.
Is TR19 a legal requirement?
No, not in itself. The Fire Safety Order 2005 still requires the responsible person to manage fire risk, and grease in the extract is part of that. Many insurance policies also require TR19 adherence.
Can the work be done while we are closed?
Yes. Tell us your opening hours when you ask for a quote and we’ll plan the visit around them.
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.
When something else is needed
TR19 inspection can’t fix everything, and we’d rather say so up front. It will not put right:
- Mechanical faults in the extract
- Fire safety duties beyond the extract system
- Design faults in the extract system
If you’re not sure, just give us a ring on 0345 646 2711, or email photos and we’ll give you a straight answer.
