- Gaps where filters have been removed
- A canopy that drips grease
How it works
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool first, and the area around the work is covered and protected. On site, it takes a short visit, depending on how many filters the canopies hold. Before the visit, a few pictures of the system and how to reach it help us plan the work in Farnham.
- First, we check the canopies and the filters in them.
- Any damaged or missing filters are noted.
- We exchange the dirty filters for a clean set.
- We check the filters are seated and the canopy is ready to use.
- We tell you if the plenum or canopy needs a clean.
How to prepare
- Name a contact who can let us in at the agreed time
- Tell us about site rules, permits or sign-in
- Clear the space around the work

Grease filter exchange for kitchens and businesses in Farnham
The filters in the canopy are the first thing cooking vapour meets. Their job is to stop grease getting further into the system and they do it best when they’re clean. Our grease filter exchange service swaps dirty filters for clean ones on a schedule. The work covers mesh filters, island canopies and wall canopies, and the jobs we see most are grease filters clogged with grease and grease left in baffles after washing.
For a pub, café or restaurant in a town like Farnham, losing a day’s trade to cleaning is not an option, so the work is done after service, overnight or on a closed day. By the next service, the kitchen is ready to cook in again.
The paperwork matters as much as the work. You get a written report with pictures after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

What the work involves, part by part
Canopy filter housings
The trough or channel under the filters fills with grease. We point it out if it needs cleaning.
School, care home and staff kitchens
Kitchens that cook for set mealtimes still load their filters, though often more slowly.
Honest limits
Not every problem is solved by grease filter exchange, and we’ll tell you before any work starts. It will not put right:
- A noisy or failed extract fan
- Greasy ducts and risers that a filter change will not reach
- A canopy too small for the cooking beneath it
If you’re not sure, just phone us on 0345 646 2711 or email us and we’ll give you a straight answer.
Parts of the system we cover
- School and hospital kitchens
- Baffle filters
- Restaurants and pubs
- Island canopies
- Mesh filters
- Wall canopies
What staff can safely do
If your staff spot something 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.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
Farnham questions
Can you work in Farnham outside opening hours?
Yes. We work evenings, overnight and at weekends. The work in Farnham can fit around your hours. Just call us on 0345 646 2711, or email photos with your opening times and we’ll plan around them.
Which fire authority looks after Farnham?
That’s Surrey Fire and Rescue Service. TR19® isn’t law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
What’s the right interval for changing filters?
It varies with the type and amount of cooking. If filters clog early, the interval needs shortening, and we can change it.
Do we need to close while you work?
Not typically. We work when the area is out of use, such as evenings, overnight, early mornings or weekends, so the site can carry on as normal.
Do you cover Farnham?
Yes. Our area takes in London and the counties of South East England, Farnham included.
Do you survey before quoting?
Yes. For many sites, pictures and a few details are enough, and larger or hidden systems get a visit.
Can you look after several sites?
Yes. Tell us the addresses and what each needs and you’ll get one fixed quote.
What types of filter do you exchange?
The common types of grease filter: baffle and mesh. Mention how many canopies you have when you get in touch, or we’ll check on the first visit.
Do you need grease filter exchange in Farnham?
Sometimes a filter is taken out and never put back. A missing filter leaves an open route into the system where it settles out of sight.
Keep an eye out for these warning signs:
- Grease building up behind the canopy filters
- Grease dripping from the canopy
- Filters that come out of the sink still dirty
- Gaps where filters have been removed
Where a hall near St Joan of Arc's Church, or anywhere in Farnham, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

Grease, kitchens and Farnham
According to Food Standards Agency records, there are about 20 pubs, bars and clubs and about 3 hotels and B&Bs within about 1.5 miles of central Farnham. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Farnham sits within the area of Surrey 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. It’s Waverley council that sends environmental health officers to food businesses in Farnham. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Before-and-after pictures from each clean are a simple way to show the extract is in hand.
If you cook for passing trade around Farnham station, the extract can be cleaned between your last and first customer. For schools such as Farnham College, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.

What happens if it’s left?
When filters block, extraction suffers. The kitchen gets hotter and smokier while the fan strains. A regular exchange keeps the airflow where it should be. Grease, dust and wear all build up with time.
