What staff can safely do
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
TR19 inspection in Ashridge
Think of a TR19 inspection as the diagnosis before the treatment. Readings, photos and notes on access are gathered from end to end, so the clean can be planned properly. Typical jobs include sections of duct that can’t be reached and kitchens taken over with no cleaning records, on access surveys, deposit thickness tests and wet film thickness tests.
For a kitchen in or near Ashridge, the visit is planned around opening hours and the journey, and the clean itself is the same full TR19® job as in any town: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
Good records are part of the job. You get a written report with photos after every visit, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

Ashridge questions
Who is the fire and rescue service for Ashridge?
Ashridge is in the area of Hertfordshire Fire and Rescue Service. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Do you work in villages like Ashridge?
Yes, we work in villages as well as towns, and Ashridge is covered. Let us know about access, parking and anything unusual about getting there when you book.
What is TR19?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Can you verify a clean after it’s been done?
A post-clean check records grease readings and pictures after the work, whoever did the clean.
At what point does grease need cleaning?
The TR19® Grease figures are a mean of 200 microns or less between cleans, and immediate spot cleaning wherever a reading hits 500 microns. We show your readings against those figures.
What about areas you can’t get to?
We never leave them off the paperwork. You’ll know exactly which parts weren’t reached and why, and we can quote to improve the access.
Do you work with multi-site operators?
Yes. We work across South East England and London, so sites at different addresses can be planned together on one programme. Each site gets its own report and photos.
Will you produce a report for our insurer?
Yes. Our TR19 audits cover readings, photos, access and a recommended cleaning interval. It’s set out for your insurer or broker.

Aftercare tips
Here’s the after-treatment advice, short and simple:
- Keep the route to access panels clear
- Mention new equipment or longer hours at the next test
- Store grease readings where your insurer can see them
- Look out for grease drips round the canopy edge
The audit report is set out to pass straight to your insurer or broker, with readings, photos and any areas not accessible.
When cooking hours or the menu change, check the interval still fits. A quick grease test answers the question.
When it’s something else
Before booking, it helps to know what’s not included:
- Fan breakdowns, which need a repair visit
- The responsible person’s own fire risk assessment
- The grease itself, which needs a full or spot clean
If you’re not sure, just call us on 0345 646 2711 or email us and we will give you a straight answer before booking.

What the work involves, part by part
Restaurants, pubs and hotels
Heavy use under BESA guidance, 12 to 16 hours a day, means a clean at least every 3 months, and readings show whether that is enough.
Schools, hospitals and care homes
School and college kitchens still need their extract checked. Testing shows whether the interval suits.

Signs you need TR19 inspection in Ashridge
TR19® is the benchmark that insurers, fire officers and EHOs refer to. It is not legislation; the legal duty comes from the Fire Safety Order 2005, under which the responsible person must reduce fire risk, and in a kitchen that means keeping grease under control.
Most sites get in touch when they notice one of these:
- An insurer’s request for a TR19 audit
- Pre-clean surveys before a first TR19 clean
- Extracts that may be over the 200 micron mean
- Uncertainty over how often to clean
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Ashridge is Hemel Hempstead Hospital, about 5.1 miles south-east.

The process
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before any work starts, and floors and nearby surfaces are sheeted. The work itself takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. Somewhere like Ashridge, lanes, gates and parking are worth mentioning in advance.
- The visit is arranged for when the kitchen isn’t busy.
- We look over the canopy, plenum, ducts, fan and discharge.
- Grease thickness is measured at set points by WFTT or DTT.
- Photos are taken at each point, and access gaps noted.
- The findings go into a report with readings, photos and a recommended next clean.
Before we arrive
- Tell us about site rules, permits or sign-in
- Allow time for equipment near the work to be turned off and cool down
- Mention any locked doors, roof access or ceiling voids

Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before work begins.
