How we handle TR19 inspection in Puttenham
A fixed schedule does not always match how a kitchen really cooks. Some kitchens build up grease faster than the minimum intervals assume, and only measurement shows it. Our readings give your risk assessment real numbers to work from. The work covers insurer audits, wet film thickness tests and post-clean checks, and the jobs we see most are surveys needed before quoting a full clean and kitchens taken over with no cleaning records.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. We agree access and timings in advance.
Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

What happens on the day
We start by comparing what we find with the survey or your photos. Anything unexpected is raised with you before we go further. After that, the work takes an hour or two for a single kitchen, longer for a large or complex system. For a village or hamlet like Puttenham, tell us about narrow lanes, gates and parking when you book.
- First we look at the system’s cleaning history, if there is one.
- The layout is traced from the canopy to the discharge.
- We note where access panels are and where more are needed.
- Grease readings are taken and pictures recorded.
- You get a report and a fixed quote for the clean.
Preparing for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Make sure someone can let us in and lock up afterwards
- Tell us about site rules, permits or sign-in

Your questions about TR19 inspection in Puttenham
Do you cover smaller places like Puttenham?
Yes. Puttenham is within the area we cover across London and the South East. Just mention lanes, gates or anything else about the site when you book.
Which fire and rescue service is responsible for Puttenham?
It’s Hertfordshire Fire and Rescue Service, which covers Puttenham. TR19® isn’t law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Why survey before a clean?
We survey, measure and photograph the system first. The survey can be done from photos and details or on site, as suits the job.
How much does TR19 inspection cost in Puttenham?
We don’t publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. You get a fixed price before work begins.
What do you need from me for a quote?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. Then ring 0345 646 2711, or email photos.
What is a WFTT or DTT grease test?
WFTT and DTT are the two methods for measuring grease thickness, in microns. We take readings at set points from canopy to fan.
Do you offer maintenance contracts?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. Each report recommends when the next visit should be.
When should we have our next grease test?
Each report recommends when to test and clean next, based on the readings and how the kitchen is used. A risk assessment based on measured grease should set the interval.

Multi-site and managed buildings
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We are happy to deal with either side and send the paperwork to whoever needs it.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
In-house cleaning or a specialist?
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
Puttenham kitchens: local notes
Hertfordshire Fire and Rescue Service covers Puttenham. 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. We cover Puttenham, about 35 miles from central London, as part of our work across London and the South East. We work evenings, overnight and at weekends, so the visit fits around the site.
If you look after a school kitchen, at a school such as Long Marston VA Church of England Primary School or anywhere near Puttenham, the holidays are the usual time for a TR19® clean. Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Ascott House is about 4.9 miles north), access may need planning.
Puttenham is about 4 miles east of Aylesbury, in Hertfordshire. We provide TR19 inspection for businesses, landlords and public buildings in Puttenham and the rest of Hertfordshire. Our area takes in 381 places across Hertfordshire, large and small. We also work in Milton Keynes, around 15 miles away.
Postcode districts we cover here for TR19 inspection: HP23. TR19 inspection is available to premises on Church Road, Astrope Lane and Draytonmead Farm Road and nearby roads. We also cover Astrope (1 mile east), Long Marston (1 mile north-east), Buckland (1 mile south), Aston Clinton (2 miles south) and Broughton (2 miles west). Further out, we also cover Hemel Hempstead (12 miles south-east), Berkhamsted (7 miles south-east), Tring (3 miles south-east), Chorleywood (15 miles south-east), Grovehill (12 miles south-east) and Woodhall Farm (12 miles south-east).
Near you in Puttenham
Puttenham’s nearest station is Cheddington station, about 3.3 miles north-east. Well-known places in the area include Tindal Centre (3.8 miles west) and Pitstone Green Museum (3.2 miles east). For a walk, there’s Haddington Hill and College Lake nature reserve.
Between visits
Think of this as the after-treatment advice, in brief:
- Clean grease off the canopy between professional cleans
- File every inspection report with your certificates
- Report grease dripping from the canopy
- Mention new equipment or longer hours at the next test
The report recommends when the system should next be cleaned and tested, from the measured grease and the kitchen’s hours.
Close the access gaps found during inspection, so every part of the duct can be cleaned.
Signs you need TR19 inspection in Puttenham
Some parts of a system are hard to reach, so those sections can be skipped time and again. A survey finds the sections that can’t be reached, so panels can be fitted.
Clients normally contact us after spotting something like this:
- Kitchens taken over with no cleaning records
- Systems that need surveying before cleaning
- Extracts that may be over the 200 micron mean
- Cleaning intervals that may not suit the kitchen
A hospital like Tindal Centre, about 3.8 miles west, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

When it’s something else
An honest diagnosis matters more to us than a booking, so here’s what TR19 inspection won’t do:
- Sections with no access, until panels are fitted
- The responsible person’s own fire risk assessment
- Fan breakdowns, which need a repair visit
If you’re not sure, just give us a ring on 0345 646 2711 or send us an email and we will give you a straight answer before you book.

Why it’s worth doing now in Puttenham
If there’s a fire or a claim, your insurer may ask for TR19 records. Without them, a claim can be reduced or refused. An up-to-date inspection report is a good place to start. With notice, the visit to Puttenham can be fitted around your bookings and events.
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.
