TR19 inspection for kitchens and businesses in South Harefield
BESA’s minimum cleaning frequencies depend on how long the kitchen cooks each day: every 3 months for heavy use of 12 to 16 hours a day, every 6 months for moderate use of 6 to 12 hours, and every 12 months for light use of 2 to 6 hours. Grease testing shows whether your kitchen needs cleaning more often than that. Common call-outs are for systems that need surveying before cleaning and post-clean verification after another contractor’s clean, across pre-clean surveys, access surveys and post-clean checks.
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.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

Looking after it afterwards
Here’s the after-treatment advice, short and simple:
- Keep to the recommended interval
- Clean or swap grease filters as often as the kitchen needs
- Keep access panels clear and unpainted
- Look out for grease drips round the canopy edge
After post-clean verification, file the results with the cleaning certificate. The pair gives a clear record of the clean and the check.
Revisit the cleaning interval whenever the menu or hours change. Fresh readings show whether it needs to change.
Questions from South Harefield
Who enforces fire safety at workplaces in South Harefield?
South Harefield is in the area of Buckinghamshire Fire and Rescue Service. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Who would carry out a food hygiene inspection at a kitchen in South Harefield?
In South Harefield, it’s Hillingdon council that carries out food hygiene inspections. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
What about areas you cannot get to?
They’re marked on the report. In ductwork, new access panels are often the answer, which we can install.
Do you work in South Harefield?
Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, and that includes South Harefield.
Will you produce a report for our insurer?
Yes, for kitchens across the South East and London. Share the insurer’s request so the report addresses it.
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.
Where does the waste go?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. We don’t leave it behind.
What does TR19 inspection cost?
There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. We fix the price before work begins.
Why deal with it now?
Without readings, you are guessing when to clean. Any reading of 500 microns or more needs immediate spot cleaning under TR19® Grease, and you can only act on that if you’ve measured it. Out of sight is the usual reason a rural system goes too long without attention.
What you pay depends on the size of the system, what state it’s in and access to every part of it. You get a fixed price before any work starts, so you know where you stand.

Grease, kitchens and South Harefield
According to Food Standards Agency records, there are about 11 bars, pubs and nightclubs within 1.5 miles or so of the middle of South Harefield. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. South Harefield sits within the area of Buckinghamshire 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 Hillingdon council that sends environmental health officers to food businesses in South Harefield. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A dated certificate in the maintenance file answers the question before it’s asked.
A hospital like Harefield Hospital, about 1.2 miles north, is the kind of site where a kitchen may cook for patients, staff and visitors all day. Term dates shape school work: for a school like Harefield Infant School, an extract clean fits neatly into a half-term or summer break. If you run a church or community hall kitchen, near Church of St Mary the Virgin or elsewhere in South Harefield, its extract still collects grease from every lunch and event.
South Harefield is about 3 miles west of Ruislip, in Buckinghamshire. Sites in South Harefield get the same service as everywhere we cover: diagnosis first, a fixed price, out-of-hours working where necessary and a written report with photos.

Local landmarks in South Harefield
Around South Harefield, our work takes us to kitchens and buildings near The Harefield Academy, The River Garden pub and The Green and the streets around them. South Harefield’s nearest station is Denham station, roughly 1 mile south-west of the centre. Well-known places in the area include Hillingdon Museum and Archives Services (3.1 miles south) and The Pavilions (3 miles south). For a walk, there’s Horse Shoe Bay and Dews Farm Sand Pits.
Staff cleaning versus specialist work
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.
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
How the visit works
Night work is normal for us. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. The visit itself takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. Visits to a village like South Harefield are booked in advance, at a time that suits whoever runs the site.
- We agree a time when the kitchen is closed or quiet.
- Every part of the system is examined, end to end.
- We take WFTT or DTT readings at set points along the system.
- Each test point and any access problems are photographed.
- We send a report setting out the readings, photos and next steps.
Preparing for the visit
- Tell us about site rules, permits or sign-in
- Allow time for equipment near the work to be turned off and cool down
- Agree a time when the area can be out of use
