About our grease filter exchange in Ashendon
Each visit is quick and tidy. We lift out the dirty filters and fit a clean set and make sure there are no gaps between them. Anything that needs attention is pointed out. Typical jobs include grease left in baffles after washing and a canopy running with filters missing, on baffle filters, school and hospital kitchens and restaurants and pubs.
In a village or hamlet like Ashendon, the kitchens that need extract cleaning are normally a pub, a school, a care home or a hall kitchen, wherever there is one. Every one of them still needs its extract kept clear of grease.
Nothing is signed off by word of mouth: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

What grease filter exchange looks like in Ashendon
Ashendon is covered by Buckinghamshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. We cover Ashendon, about 44 miles from central London, as part of our work across London and the South East. A survey and a fixed quote come first, then the visit at a time that suits you.
Where a hall near Parish Church of St Mary the Virgin, or anywhere in Ashendon, hosts lunch clubs or events, its extract gathers grease just as a café’s does. Historic houses near Ashendon, such as Waddesdon Manor about 2.3 miles north-east, are a reminder that older buildings with event kitchens can have long, awkward duct routes.
Ashendon is about 5 miles north of Thame, in Buckinghamshire. Every kind of commercial site in Ashendon, grease filter exchange is something we can help with.

What your team can do, and what needs us
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, alongside our reports.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That’s our job.

What else we do in Ashendon
Landlords, agents and facilities managers
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side and send the paperwork to whoever needs it.
FAQs for Ashendon
Which environmental health team covers Ashendon?
Kitchens in Ashendon are inspected by Buckinghamshire council’s environmental health officers. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
Do you work overnight in Ashendon?
Yes, we can come after you close and finish before you open. That way a site in Ashendon doesn’t have to lose a day’s trading. Just phone us on 0345 646 2711 or drop us a line with your opening times and we’ll plan around them.
Can you come out in an emergency?
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.
Are you accredited?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.
Does a filter exchange replace TR19 cleaning?
It is not. Clean filters help keep grease down, but the ducts and plenum still need cleaning at the right interval.
Who is responsible for fire safety on the premises?
Under the Regulatory Reform (Fire Safety) Order 2005, it’s the responsible person: often the employer, owner or occupier. Landlords, facilities managers and managing agents can also hold responsibility.
What happens if you can’t reach some of it?
They’re marked on the report. In ductwork, new access panels are often the answer, which we can install.
How much notice do you need?
The more notice, the better, particularly for night and weekend visits. We normally quote within one working day, and emergencies are covered by our 24/7 line.
When it’s something else
It’s worth knowing the limits before booking:
- Grease already built up in the ductwork, which needs a full TR19 clean
- Cooking smells reaching neighbours, which need odour control
- A canopy that needs a proper clean
Not sure which it is? You can ring 0345 646 2711 or send us an email and we will tell you honestly before you book.
What we work on in Ashendon

When to call us in Ashendon
What a kitchen cooks affects how fast filters clog. Frying, grilling and chargrilling produce far more grease than steaming or baking so no single schedule suits every kitchen.
The symptoms we’re asked about most are:
- Poor airflow through the filters
- Grease dripping from the canopy
- A canopy running with filters missing
- Filter washing that keeps being missed
Healthcare kitchens, like those at hospitals such as St John's Hospital (about 4.6 miles east), often cook for long hours, which puts them in BESA’s heavier-use bands.

How the visit works
There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. Most of the time goes on the work itself, which takes a short visit, depending on how many filters the canopies hold. The timing of a visit to Ashendon is set by you, and the travel is our side of the planning.
- The filters in each canopy are measured and counted.
- We set the interval with you.
- On each visit, we remove the greasy filters.
- A clean set is fitted and checked for gaps.
- We take the greasy set away and confirm the next date.
Preparing for the visit
- Let us know when the site is closed or quiet
- Mention any locked doors, roof access or ceiling voids
- Clear loose items from the work area
How to get a quote
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. After that, you get a fixed price for the work, before work begins.
Advice
Looking after it afterwards
A little care between visits keeps the system in better shape. Our advice:
- Do not refit a filter that’s bent
- Keep every filter in place during service
- Make sure we can reach the canopy on exchange day
- Always run the extract while cooking
Keep an eye out for filters that have been taken out. Gaps let grease into the plenum, so let us know if one goes missing or gets damaged.
Filters that are left too long stop protecting the system. Getting onto a regular exchange now keeps grease out of the plenum and ductwork until the next TR19 clean.
