How we handle grease filter exchange in Four Marks
Across Four Marks, our filter exchange suits restaurants, pubs, cafés, schools, care homes and other kitchens, whether there’s one canopy or many. We can come before or after service, so cooking isn’t interrupted. Typical jobs include filters so greasy the air can barely pass and staff short of time to wash filters, on restaurants and pubs, wall canopies and school and hospital kitchens.
In a smaller place like Four Marks, many kitchens sit in older buildings or later extensions, with the duct running through a roof space or up an outside wall. Long horizontal runs like that hold grease and need access panels to reach.
The paperwork matters as much as the work. Each visit is written up with photos, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

What affects the quote in Four Marks
Some jobs are bigger than they look, and some smaller. The main factors:
- The condition we find in the survey
- Whether several sites go on one quote
- When the work can happen, such as evenings, overnight or weekends
- How easy every part is to reach
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we’ll explain each part.
Helping us quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Detail shots of panels, filters and grilles
- A few general shots of the system
- Problems your staff have spotted
Quotes are quick. Call or email with a few details and you’ll usually have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
Common questions in Four Marks
Can the work in Four Marks be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. That way a site in Four Marks doesn’t have to lose a day’s trading. Just call us on 0345 646 2711 or send us an email with your opening times and we will plan around them.
Will you come out to Four Marks?
Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.
Which kinds of sites do you work on?
Any commercial site with kitchens or ventilation, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
Can we skip TR19 cleans if the filters are changed regularly?
No, the two work together. TR19® cleaning covers the canopy, plenum, ductwork and fan and comes with a certificate and photo report.
Do you survey before quoting?
Yes, every time. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
How long does the visit take?
On site, it takes a few minutes per canopy, longer for a large kitchen with several canopies. Larger systems naturally take longer, and the quote will say how long.
What if some of our filters are damaged?
A bent filter leaves a gap for grease. We flag any we find so they can be replaced.
Do you have insurance?
Yes. We are fully insured, and the details are available on request.
Aftercare tips
Simple habits between visits make a real difference. We recommend:
- Don’t let the full clean slip because filters are changed
- Keep canopy surfaces wiped down
- Tell us if the menu or opening hours change
- Do not refit a filter that is bent
If the plenum behind the filters looks greasy, we say so. That might mean bringing a TR19® clean forward and we can book that in.
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.

What grease filter exchange looks like in Four Marks
The fire and rescue service for Four Marks is Hampshire and Isle of Wight Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. About 49 miles out from central London, Four Marks is part of the South East area we work across. The visit is fixed around your opening hours, not ours.
Volunteers running a hall kitchen near Church of the Good Shepherd, or anywhere in Four Marks, may not know when the extract was last cleaned, and a grease test settles it. If you run catering at a historic house or estate in the area (Bentworth Hall is about 2.7 miles north), event kitchens in older buildings often have awkward duct runs that need planning. Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Four Marks is Alton Community Hospital, about 3.3 miles north-east.

What the work involves, part by part
Canopy filter housings
We check that filters sit snugly in the housing at each visit, because gaps let grease through.
Busy restaurant and pub kitchens
In a busy kitchen, filter washing is easy to skip. A regular exchange means nobody has to remember.
When something else is needed
Not every problem is solved by grease filter exchange, and we’d rather say so up front. It won’t put right:
- A heavily greased plenum or canopy, which needs cleaning to TR19
- Greasy ducts and risers that a filter change won’t reach
- Smell complaints that need odour control equipment
Not sure which it is? You can call us on 0345 646 2711 or use the quote form and we will tell you honestly.
Parts of the system we cover
- Baffle filters
- Wall canopies
- School and hospital kitchens
- Mesh filters
- Restaurants and pubs
- Island canopies
Multi-site and managed buildings
When the building owner and the occupier are different, 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.
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so records stay tidy.
What happens on the day
When we arrive, we check the system against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. After that, the work takes well under an hour for most canopies. In a place like Four Marks, we fit the visit around your hours.
- We look at the canopies and the condition of the filters.
- Any damaged or missing filters are noted.
- Greasy filters are swapped for clean ones.
- We check the filters are seated and the canopy is ready to use.
- Anything that needs attention, such as a greasy plenum, is pointed out.
Getting ready for the visit
- Make sure someone can let us in and lock up afterwards
- Let us know about permits to work or site inductions
- Have your last certificate or report to hand

In-house cleaning or a specialist?
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. Leave those to us.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
