Buckinghamshire · TR19 inspections and grease testing
TR19 inspections in Beaconsfield
We cover Beaconsfield for TR19 inspections, grease thickness testing, pre-clean surveys and post-clean verification. Fixed quotes, work around your opening hours and photo reports on every job.
- Sites with gaps in their extract records
- Insurance renewals needing proof of TR19 cleaning
- Extracts that may be over the 200 micron mean
How the job changes from site to site
Extract fan and discharge
We look at where the extract discharges outside, since grease reaches the very end of the system.
Schools, hospitals and care homes
School and college kitchens still need their extract checked. Testing shows whether the interval suits.
TR19 inspection in Beaconsfield, done properly
Insurance policies often require evidence of TR19® cleaning and inspection. Missing records can lead to a claim being reduced or refused. A TR19 audit sets out the system’s condition, with readings and photos, for sites in Beaconsfield and the rest of Buckinghamshire. The work covers deposit thickness tests, pre-clean surveys and insurer audits, and people most often call us about sections of duct that can’t be reached and pre-clean surveys before a first TR19 clean.
Kitchens in towns like Beaconsfield are often in older buildings that were never designed for them, which can mean awkward duct routes, long flat runs and not enough access panels. Sections we can’t reach are listed on the report, and access panels can be added.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

Grease, kitchens and Beaconsfield
The FSA’s data shows about 12 pubs, bars and clubs registered within about 1.5 miles of central Beaconsfield. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Fire safety in Beaconsfield falls to Buckinghamshire Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. It’s Buckinghamshire council that sends environmental health officers to food businesses in Beaconsfield. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Our report lists what was cleaned and when, which is useful to have ready.
Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Beaconsfield is Chalfonts and Gerrards Cross Hospital, about 3.7 miles east. If you run a church or community hall kitchen, near Church of St Michael and All Angels or elsewhere in Beaconsfield, its extract still collects grease from every lunch and event.
Beaconsfield is about 5 miles east of High Wycombe, in Buckinghamshire. Whatever kind of site you run in Beaconsfield, we can take on TR19 inspection. Visits can be booked for evenings, overnight or weekends so trading isn’t interrupted. Beaconsfield is one of 263 towns, villages and districts in Buckinghamshire where we work for commercial clients. There’s also a page for Reading, about 18 miles away.
Every address in HP9 is covered for TR19 inspection, from the main roads to the quietest streets. That includes premises on Station Road, Malthouse Square and Gregories Farm Lane and nearby roads. Main roads around Beaconsfield include the A40 and B474, which makes travel easy for TR19 inspection. Close by, we work in Ledborough (1 mile north-east), Forty Green (1 mile north-west), Knotty Green (1 mile north), Seer Green (2 miles east) and Beacon Hill (2 miles north-west). Within a short drive, we also cover High Wycombe (5 miles west), Chesham (7 miles north), Marlow (6 miles south-west), Amersham (5 miles north-east), Chalfont St Peter (4 miles east) and Southcourt (15 miles north-west). Being one of Buckinghamshire’s larger places, Beaconsfield has commercial sites of every size, and we cover all of them for TR19 inspection.

Questions from Beaconsfield
Can you come to Beaconsfield after we close?
Yes, we can come after you close and finish before you open. That way a site in Beaconsfield does not have to lose a day’s trading. Your opening times are the first thing we ask for.
Who would carry out a food hygiene inspection at a kitchen in Beaconsfield?
Food hygiene inspections in Beaconsfield are carried out by Buckinghamshire council. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
How much notice should we give?
That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
Do you offer maintenance contracts?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. Each report recommends when the next visit should be.
Can you quote from pictures?
Often, yes. With good photos, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
What is a WFTT or DTT grease test?
It’s a measurement of how much grease is coating the inside of the extract, by WFTT or DTT. Each reading is recorded in microns.
Can you verify a clean after it’s been done?
Post-clean verification is a check after a clean, with fresh grease readings and pictures. It can follow our own cleans or another contractor’s.
What about areas you can’t get to?
Anything we cannot 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.
What your team can do, and what needs us
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That is our job.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.

Why it’s worth doing now in Beaconsfield
Catching heavy deposits early keeps the fix small. Ignored, the layer only gets thicker. Booking now keeps it a routine visit to Beaconsfield rather than an urgent one.

Looking after it afterwards
No system stays clean for ever, but care slows the build-up. A few tips:
- Clean or swap grease filters as often as the kitchen needs
- Keep TR19 certificates, readings and reports together
- Don’t box in or cover duct access panels
- Look out for grease drips round the canopy edge
Keep the verification report next to the certificate it relates to. The pair gives a clear record of the clean and the check.
Clean, correctly fitted filters stop more grease reaching the duct. Gaps around filters let grease get past them.
Do you need TR19 inspection in Beaconsfield?
As hot, greasy air travels up the duct, it cools and leaves a film behind. The thickest layers can sit out of sight in the plenum, at bends and along flat runs.
The symptoms we’re asked about most are:
- Sites with gaps in their extract records
- Sections of duct that cannot be reached
- Ductwork where grease may be over the TR19 limits
- Extracts that have never been grease tested
Bursars and site managers at schools such as Butlers Court School tend to book extract cleaning for when the kitchen is empty.
What your quote should include
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- What paperwork you get at the end
- What’s included in the scope, part by part
- When they can work, and whether that’s outside your opening hours
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 on a regular cycle.
From a single site to a large estate, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
How it works
Your staff don’t need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Before we leave, the area is tidied and the paperwork follows. We arrive in Beaconsfield once you’ve closed and leave the site ready for the morning.
- First we book a time that will not disrupt cooking.
- The system is checked from canopy to discharge.
- Grease thickness is measured at set points by WFTT or DTT.
- We photograph the test points and record any sections we cannot reach.
- We send a report setting out the readings, photos and next steps.
Getting ready for the visit
- Make sure equipment near the work can be switched off and left to cool
- Have your last certificate or report to hand
- Name a contact who can let us in at the agreed time
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 photos, get a survey first. Either way, the quote is fixed before any work is booked.
