TR19 inspection in Ashley Green, done properly
Before any clean in Ashley Green, 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. The work covers wet film thickness tests, post-clean checks and deposit thickness tests, and the jobs we see most are heavy grease suspected in the plenum or ducts and kitchens whose menu or hours have changed.
Work in a small place like Ashley Green starts with a call to agree access and timings, 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.
The paperwork matters as much as the work. You get a written report with pictures after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Kitchen extracts in Ashley Green
Look up Ashley Green on the FSA’s food hygiene register and you will find about 3 restaurants, cafés and works canteens within about 1.5 miles of central Ashley Green. A WFTT or DTT reading tells each of those kitchens whether its grease is staying under the 200-micron mean. Fire safety in Ashley Green falls to Buckinghamshire Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. Food hygiene inspections in Ashley Green are the job of Buckinghamshire council’s environmental health team. Extraction counts as kitchen equipment, so its condition can come up on the day. A dated certificate in the maintenance file answers the question before it’s asked.
Healthcare kitchens, like those at hospitals such as Hemel Hempstead Hospital (about 5 miles east), often cook for long hours, which puts them in BESA’s heavier-use bands. If you run a church or community hall kitchen, near Parish Church of St John the Evangelist or elsewhere in Ashley Green, its extract still collects grease from every lunch and event.

What staff can safely do
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
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.
The process
The first job on site is protection: floors, worktops and anything near the work are covered. Then we make the system safe and start. It takes a couple of hours for a typical kitchen extract system, and we clear up before we go. For a village or hamlet like Ashley Green, tell us about narrow lanes, gates and parking when you book.
- After the clean, we arrange a time to check the system.
- The same access points are opened up.
- 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.
Before we arrive
- Let us know about parking and loading
- Find the previous report, if there is one
- Make sure equipment near the work can be switched off and left to cool

Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before work begins.

Questions from Ashley Green
Who enforces fire safety at workplaces in Ashley Green?
Buckinghamshire Fire and Rescue Service is the fire and rescue service for Ashley Green. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Can you get to a site in Ashley Green?
Yes, we work in villages as well as towns, and Ashley Green is covered. Photos of the system and directions to the site help us plan the visit.
What is TR19?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Do you check other contractors’ cleans?
We visit after a clean, take readings at set points and photograph the system. Any areas that weren’t cleaned properly are flagged.
Do you carry out TR19 audits for insurers?
Yes. Insurers often want evidence the extract is managed to TR19®, and an audit report gives you that, with recommendations where something needs doing.
Which accreditations do you hold?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.
At what point does grease need cleaning?
Under TR19® Grease, the mean thickness should not exceed 200 microns between cleans. Any reading of 500 microns or more needs immediate spot cleaning.
Do you survey before quoting?
Yes. Every job is surveyed first, from your photos and details, or with a visit where needed. Then you get a fixed quote.
What affects the quote in Ashley Green
The quote reflects the site in front of us. We take into account:
- How big the system is
- How easy every part is to reach
- Working hours and out-of-hours timing
- A single visit or a regular plan
Working hours, access and the scale of the site can all change the price. We take each of them into account and give you a fixed price before we start.
What we need to know
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Your opening hours and when the area is out of use
- The paperwork from the last visit, if you have it
- Close-ups of filters, grilles, hatches or access panels
- Problems your staff have spotted
There’s no standard price list, because every site is different. Instead, we look at your site first, from photos or a survey, and then give you a fixed quote. To get going, give us a ring on 0345 646 2711, or email photos.
Do you need TR19 inspection in Ashley Green?
You cannot judge grease thickness by eye. A system can look clean at the filters and be heavily coated further in, so readings are the reliable guide.
The symptoms we’re asked about most include:
- Sites with gaps in their extract records
- Checking the result of a recent clean
- Kitchen extract systems with no recent grease readings
- Ductwork where grease may be over the TR19 limits
Historic houses near Ashley Green, such as Cholesbury Manor House about 3.1 miles west, are a reminder that older buildings with event kitchens can have long, awkward duct routes.
Before you book anyone
- When the next visit should be, and why
- How VAT is shown on the quote
- What happens if part of the system can’t be accessed
- What insurance they carry
When it’s something else
We will always give you a straight diagnosis, so here’s what this work cannot put right:
- Hidden runs that need access panels first
- The legal duty, which stays with the responsible person
- A faulty or failing extract fan
If in doubt, give us a ring on 0345 646 2711 or drop us a line and we will say what we think.
Parts of the system we cover
- Deposit thickness tests
- Insurer audits
- Wet film thickness tests
- Post-clean checks
- Access surveys
- Pre-clean surveys
Landlords, agents and facilities managers
We also work for facilities teams across offices, schools and healthcare in Ashley Green and across Buckinghamshire. Work can be phased by floor, building or site to keep disruption down.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
