TR19 inspection in Farnham: the local picture
The FSA’s data shows about 3 pubs and bars registered within roughly a mile and a half of the centre of Farnham. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Farnham sits within the area of Hertfordshire 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. It’s Uttlesford council that sends environmental health officers to food businesses in Farnham. Extraction counts as kitchen equipment, so its condition can come up on the day. Before-and-after pictures from each clean are a simple way to show the extract is in hand.
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Much Hadham Palace is about 4.2 miles south-west), access may need planning. Church and community hall kitchens, near Church of St Mary the Virgin or anywhere around Farnham, are easy to forget, but their extracts collect grease like any other.
Farnham is about 2 miles north of Bishop's Stortford, in Hertfordshire. Whatever kind of site you run in Farnham, TR19 inspection is something we can help with.

About our TR19 inspection in Farnham
A pre-clean survey looks at the whole system, from canopy to discharge. We check where the access panels are and whether every section can be reached, and record grease readings at set points. Typical jobs include insurers asking for TR19 evidence and extracts that may be over the 200 micron mean, across access surveys, pre-clean surveys and wet film thickness tests.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.
Good records are part of the job. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

- Insurer audits
- Wet film thickness tests
- Deposit thickness tests
- Access surveys

Multi-site and managed buildings
Facilities teams in offices, schools and healthcare sites book us too across Hertfordshire. Larger estates can be phased building by building to keep disruption down.
For anyone managing more than one site, we can schedule visits across all of them on one quote. Each site gets its own report and pictures, so records stay tidy.
Why deal with it now?
Surveying first means the clean goes to plan. Access problems are spotted in advance rather than on the night, so the clean covers the whole system. Rural sites can’t always move to another kitchen or room when something fails.
You will not find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we will talk you through it.

Aftercare tips
Think of this as the after-treatment advice, in brief:
- Send TR19 audit reports to your insurer on request
- Never cook with filters missing
- Do not box in or cover duct access panels
- Keep to the recommended interval
Any access problems we found are listed with a suggested fix. Fitting them before the next clean means the whole system gets done.
Regular grease readings keep the cleaning interval honest. It spots changes in how fast grease builds.
How it works
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. For a village or hamlet like Farnham, tell us about narrow lanes, gates and parking when you book.
- 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.
- The results are reported, with anything missed flagged.
How to prepare
- Have your last certificate or report to hand
- Let us know about parking and loading
- Make sure someone can let us in and lock up afterwards
Getting a quote
Quotes are quick. Send a few details and photos, and we typically reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

What affects the cost of TR19 inspection
Before we fix a price, we need to know a few things. We check:
- The scale of the work
- How many systems or sites are involved
- Parking and loading at the site
- Working hours and out-of-hours timing
The price reflects the work, not guesswork. That is why every job is surveyed first, and why the quote is fixed before we start.

When you call or email, these details help:
- The paperwork from the last visit, if you have it
- Photos showing the whole system and its surroundings
- The postcode and the type of business
- Any access panels or hatches you can see

Farnham: your questions answered
Do you work overnight in Farnham?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Let us know the hours you’re closed and we will book within them.
Who carries out food hygiene inspections in Farnham?
Food hygiene inspections in Farnham are carried out by Uttlesford 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 does a pre-clean survey involve?
A survey finds out how the system is laid out, how dirty it is and what can be reached, so the clean goes to plan. Missing access panels are noted so they can be sorted first.
Is a quote from photos possible?
Yes, for many jobs. Send a few wide pictures plus close-ups of panels, filters or grilles, and we usually come back within one working day. If pictures aren’t enough, we’ll survey first.
What accreditations do you have?
Our accreditations are CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
When should we have our next grease test?
It depends on how heavily the kitchen cooks. BESA’s minimum cleaning intervals are every 3, 6 or 12 months for heavy, moderate and light use, and grease readings help set the real interval.
What is post-clean verification?
Verification means repeat readings and photos once the clean is done. The report flags anything missed.
What does TR19 mean?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t legislation, but it’s the standard people check against.
What we are called out for in Farnham
Some parts of a system are hard to reach, and grease can be missed there clean after clean. An inspection of a system in Farnham shows where access panels are missing, so the gaps can be closed.
Most sites get in touch after spotting one of these:
- Kitchen extract systems with no recent grease readings
- Insurers asking for TR19 evidence
- Sections of duct that cannot be reached
- Kitchens whose menu or hours have changed
If you run catering at a healthcare site, such as a hospital like Herts and Essex Hospital about 2.8 miles south-east, the extract may need cleaning more often than a part-time kitchen.
Questions to ask before you book
- Proof of accreditation you can verify
- What happens if part of the system can’t be accessed
- Exactly which parts of the system are covered
- Whether the price is fixed
