Grease Filter Exchange in Mortimer
Grease filter exchange for commercial sites in Mortimer and across West Berkshire. BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease.
- A canopy that drips grease
- A greasy plenum behind the filters
- Weak extraction at the canopy
How we handle grease filter exchange in Mortimer
Think of filter exchange as routine care for the extract. Between full cleans, it keeps the airflow healthy, and it saves your staff a greasy job. The full TR19 clean then gives the system its clean bill of health. If you have weak extraction at the canopy and grease building up behind the canopy filters, we can help.
Kitchens around a place like Mortimer are often in older buildings or single-storey extensions, where the duct may cross a roof void or climb an outside wall. Long horizontal runs like that hold grease and need access panels to reach.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

What grease filter exchange can’t fix
We will always give you a straight diagnosis, so here’s what grease filter exchange won’t do:
- Cooking smells reaching neighbours, which need odour control
- Grease behind the filters that a swap can’t remove
- An extract that was undersized from the start
Not sure which it is? You can phone us on 0345 646 2711 or use the quote form and we will tell you honestly before booking.
What we work on in Mortimer
- Restaurants and pubs
- Baffle filters
- Mesh filters
- Wall canopies
- Island canopies
- School and hospital kitchens
Keeping the system healthy
To keep the system working properly between visits:
- Let us know if your cooking hours increase
- Always run the extract while cooking
- Make sure no filter is left out
- Book full TR19 cleans alongside filter changes
Nothing changes for your staff, except one less greasy job. Just keep the canopy clear for the next visit and tell us if service times change.
Dripping filters are a clear sign they’re full. A clean set right away cuts the grease in the canopy and the plenum may need a clean as well.
What the work involves, part by part
Baffle filters
Baffle filters use overlapping metal blades that force the air to change direction. Grease drops out as it does.
Canopy filter housings
The trough or channel under the filters fills with grease. We point it out if it needs cleaning.

The process
Your staff do not need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. In a place like Mortimer, we fit the visit around your hours.
- First, we record the size, type and number of filters in each canopy.
- A change schedule is agreed to match the kitchen’s cooking hours.
- On each visit, the dirty filters come out of the canopy.
- Clean, dry filters are fitted in their place, with no gaps left between them.
- Anything we notice, such as bent filters or a dirty plenum, is pointed out.
Getting ready for the visit
- Mention any parking or loading restrictions
- Make sure equipment near the work can be switched off and left to cool
- Let us know when the site is closed or quiet

Your questions about grease filter exchange in Mortimer
Who inspects food businesses in Mortimer?
The local authority for Mortimer is West Berkshire council, and its environmental health team does the inspecting. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Who is the fire and rescue service for Mortimer?
Mortimer is in the area of Royal Berkshire Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
What types of premises do you cover?
Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.
Do you take the used filters away?
We take them away. That’s how an exchange works: you always have a clean set fitted, with no washing for your team.
What should go in our maintenance log?
The reports and certificates from each visit, plus your own logs. They’re what an insurer, fire officer or EHO may ask for, so keep them where they can be found quickly.
Can you come out in an emergency?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, and the emergency line covers the rest.
Do you survey before quoting?
Yes. For many sites, photos and a few details are enough, and larger or hidden systems get a visit.
Is filter exchange enough instead of a full extract clean?
No. Some grease passes the filters as vapour and settles in the ducts, so the full system still needs cleaning to TR19.
What grease filter exchange looks like in Mortimer
The FSA’s food hygiene register shows about 6 restaurants, cafés and works canteens in and around Mortimer, up to about a mile and a half out. Any of those kitchens with a canopy relies on its filters to catch grease before it reaches the duct. Mortimer is covered by Royal Berkshire 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. Kitchens in Mortimer get their food hygiene inspections from West Berkshire council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Our report lists what was cleaned and when, which is useful to have ready.
Term dates shape school work: for a school like Mortimer St John's C.E. Infant School, an extract clean fits neatly into a half-term or summer break. Where a hall near Mortimer Methodist Church, or anywhere in Mortimer, hosts lunch clubs or events, its extract gathers grease just as a café’s does. If your kitchen is in a listed or historic building, like the houses around Mortimer (Stratfield Saye House is about 3.6 miles south-east), fitting access panels needs care.

What staff can safely do
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We’ll take a look and send you a fixed quote.
