Grease filter exchange in Thornborough, done properly
A clean set of filters is a simple, regular dose of prevention. It keeps airflow up and grease down between full cleans, and it saves your staff a greasy job. Full TR19 cleaning still comes at the right interval, with a certificate. The work covers mesh filters, restaurants and pubs and wall canopies, and the jobs we see most are grease dripping from the canopy and gaps where filters have been removed.
Somewhere as small as Thornborough, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Every one of them still needs its extract kept clear of grease.
Nothing is signed off by word of mouth: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Questions from Thornborough
Who carries out food hygiene inspections in Thornborough?
Kitchens in Thornborough are inspected by Buckinghamshire council’s environmental health officers. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Who enforces fire safety at workplaces in Thornborough?
Thornborough 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.
What if parts of the system cannot be reached?
We record them on the report, with a note of where it is, and we explain what access is needed, for example new access panels.
What’s the right interval for changing filters?
There’s no single answer. The schedule is based on how heavily you cook, and adjust it if needed.
What happens to the dirty filters?
They leave with us. That is the point of an exchange: clean filters in, dirty ones out and nothing greasy left on site.
Do you offer emergency callouts?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we will talk you through the next steps.
Can you give a price for filter changes?
Every kitchen is different, so we quote once we know your filters and schedule. You get a fixed price before the service starts.
Is filter exchange enough instead of a full extract clean?
No. Filter exchange works between full cleans, not instead of them. A TR19® clean deals with the whole system, with a certificate and photo report.
Grease, kitchens and Thornborough
Kitchens in Thornborough get their food hygiene inspections from Buckinghamshire council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A dated certificate in the maintenance file answers the question before it’s asked. Fire safety in Thornborough falls to Buckinghamshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Buckingham Community Hospital is the nearest hospital to Thornborough, about 3 miles west. Church and community hall kitchens, near Church of St Mary or anywhere around Thornborough, are easy to forget, but their extracts collect grease like any other.

Leave it or put it right?
Some kitchens in Thornborough wash filters themselves to save the cost of a service, and that can work if it’s done thoroughly and on time. Where it slips, an exchange service takes the job off staff. In a small place like Thornborough, a system that fails can take a site out of use.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re not sure what’s needed, phone us on 0345 646 2711 or use the quote form for straight advice and a fixed quote.

When to call us in Thornborough
Kitchens in Thornborough, as everywhere, find filter washing slips down the list on busy weeks. It only takes a couple of missed weeks for filters to fill with grease.
It’s time to book a visit if you see:
- Filter washing that keeps being missed
- Weak extraction at the canopy
- Filters so greasy the air can barely pass
- Grease collecting in the filter channels
Stowe House, about 4.9 miles north-west, is one of the historic houses near Thornborough; if you run event catering at a venue like that, cleans can be booked between functions.

When it’s something else
Some problems need a different service or another trade:
- Odours from the discharge that filters won’t stop
- Grease deep in the extract system
- A heavily greased plenum or canopy, which needs cleaning to TR19

What the work involves, part by part
The plenum
The plenum is the space behind the filters. Grease that gets past the filters settles there.
Busy restaurant and pub kitchens
The more a kitchen cooks, the more grease the filters see. Changing them on time protects the ducts behind.
