- Cleaning intervals that may not suit the kitchen
- Kitchen extract systems with no recent grease readings
- Confirming a clean reached the whole system
Keeping the system healthy
Results last longer with the right care. Here’s what we suggest:
- Keep access panels clear and unpainted
- Flag changes in how much frying the kitchen does
- Book the next test on the date in the report
- Flag oily drips near the extract
Where sections couldn’t be reached, the report says where access panels would help. 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.
TR19 inspection in Twyford
BESA’s minimum cleaning frequencies depend on how long the kitchen cooks each day: heavy use (12 to 16 hours a day) every 3 months, moderate use (6 to 12 hours) every 6 months and light use (2 to 6 hours) every 12 months. Grease testing shows whether your kitchen needs cleaning more often than that. If you’re dealing with missing access panels found on survey and extracts that have never been grease tested, we can put it right.
Work in a small place like Twyford starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.

Twyford questions
Can school kitchens in Twyford be cleaned in the holidays?
Yes, and it’s the easiest time to do it. The FSA’s register shows about 2 schools and colleges with food registrations within roughly a mile and a half of Twyford. Just phone us on 0345 646 2711 or email us with your term dates and we will plan around them.
Can you get to a site in Twyford?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
What is grease thickness testing?
Grease thickness testing measures the layer of grease on the duct surfaces, by WFTT or DTT. Each reading is recorded in microns.
Can you inspect our extract for our insurance company?
Yes. Our TR19 audits cover readings, photos, access and a recommended cleaning interval. It’s set out for your insurer or broker.
How far ahead should we book?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
What’s TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not law, but it’s the benchmark.
Which sectors do you work in?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Which accreditations do you hold?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.
Managing agents and facilities teams in Twyford
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
We also work for facilities teams across offices, schools and healthcare across Hampshire. Work can be phased by floor, building or site to keep disruption down.
Common problems we fix in Twyford
When a site in Twyford changes owner or cleaning contractor, the records don’t always follow. With no history, the current state of the extract is a guess.
Most sites get in touch after spotting something like this:
- Pre-clean surveys before a first TR19 clean
- Checking the result of a recent clean
- Systems cleaned on a calendar with no measurements
- Kitchens taken over with no cleaning records
For kitchens close to Shawford station, where the day often starts early and ends late, the extract can be cleaned overnight.
What to look for in a quote
- Whether a survey comes first
- Exactly which parts of the system are covered
- What records you’ll receive afterwards
- When the next visit should be, and why
What happens if it’s left?
Sites in Twyford that have never measured grease can’t tell whether their cleaning interval suits the kitchen. Measured readings let a competent person set the interval. Systems in rural buildings are often out of sight and out of mind.
The cost depends on how big the system is, the condition it’s in and how easy it is to reach. You get a fixed price before work begins, so you know where you stand.
Why book with us
- Accredited under CHAS and SafeContractor, with ISO 9001
- Evenings, overnight and weekends, plus 24/7 emergency callout
- A single point of contact for sites across the South East and London
- Ventilation hygiene specialists since 2009

What we do, step by step
Everything the job needs comes with us, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. The visit takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. In a small place like Twyford, the journey is planned ahead and the visit arranged around the site’s hours.
- The visit is arranged for when the kitchen isn’t busy.
- We look over the canopy, plenum, ducts, fan and discharge.
- We take WFTT or DTT readings at set points along the system.
- Photos are taken at each point, and access gaps noted.
- The findings go into a report with readings, pictures and a recommended next clean.
How to prepare
- Arrange a key holder or contact on site
- Let us know when the site is closed or quiet
- Allow time for equipment near the work to be turned off and cool down

Twyford kitchens: local notes
The FSA’s food hygiene register includes about 4 pubs and bars within 1.5 miles or so of the middle of Twyford. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Environmental health officers from Winchester City council inspect food businesses in Twyford. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Our report lists what was cleaned and when, which is useful to have ready. Fire safety in Twyford falls to Hampshire and Isle of Wight 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.
Healthcare kitchens, like those at hospitals such as St John's Rooms And Chapel (about 2.9 miles north), often cook for long hours, which puts them in BESA’s heavier-use bands. Bursars and site managers at schools such as Twyford St Mary's Church of England Primary School tend to book extract cleaning for when the kitchen is empty.
