How we handle grease filter exchange in Greatness
Each visit is quick and tidy. The greasy filters come out, clean ones go in and make sure there are no gaps between them. If something looks wrong, we tell you. The work covers restaurants and pubs, wall canopies and island canopies, and the jobs we see most are filter washing that keeps being missed and hand-washed filters that still look greasy.
Kitchens around a place like Greatness are often in older buildings or single-storey extensions, with the duct running through a roof space or up an outside wall. Flat runs collect grease and need proper access to clean.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

For landlords and multi-site operators
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side and send the paperwork to whoever needs it.
We regularly work with managing agents. Send the address, what’s needed and how access works, and we will send a fixed quote.
Keeping the system healthy
Here’s the after-treatment advice, short and simple:
- Keep canopy surfaces wiped down
- Keep every filter in place during service
- Do not refit a filter that is bent
- Always run the extract while cooking
Fresh filters improve airflow at the canopy from the moment they’re fitted. Always run the extract during cooking so the filters do their job.
Dripping filters are a clear sign they’re full. Changing them now reduces the fuel above the cooking and the plenum may need a clean as well.
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 before any work starts, and the area around the work is covered and protected. The work itself takes a short visit, depending on how many filters the canopies hold. We plan the journey to Greatness and bring what the job is likely to need.
- We start by noting how many filters you have and what type they are.
- We agree a schedule that suits how much the kitchen cooks.
- Each visit starts with the used filters being removed.
- Clean filters go straight back in, seated properly with no gaps.
- We flag any damaged filters or anything wrong with the canopy.
Before we arrive
- Mention any parking or loading restrictions
- Make sure equipment near the work can be switched off and left to cool
- Clear loose items from the work area
Ask for a quote
Quotes are quick. Call or email with a few details and you will normally have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.

Signs you need grease filter exchange in Greatness
Hand-washed filters often come back still greasy. Grease lodges deep in baffles and mesh and a sink wash rarely reaches it.
Any of these means the system needs a check-up:
- Staff short of time to wash filters
- Filters that leave gaps in the canopy
- Smoke and heat lingering under the hood
- Blocked baffle filters
Term dates shape school work: for a school like St John's Church of England Primary School, an extract clean fits neatly into a half-term or summer break.

More services for Greatness
Grease, kitchens and Greatness
Food Standards Agency records include about 11 bars, pubs and nightclubs and about 3 hotels and guest houses in Greatness and the streets around it, up to about 1.5 miles out. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Greatness sits within the area of Kent 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. It’s Sevenoaks council that sends environmental health officers to food businesses in Greatness. 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.
If you run a café or takeaway near Bat & Ball station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits. Volunteers running a hall kitchen near St John the Baptist, or anywhere in Greatness, may not know when the extract was last cleaned, and a grease test settles it.

Your questions about grease filter exchange in Greatness
Do you cover smaller places like Greatness?
Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.
Can the work in Greatness be done at night or at weekends?
Yes, nights and weekends are routine for us. The site is handed back ready to open. When you phone us on 0345 646 2711, or email photos, mention when the site is quiet.
Do you provide a certificate or report?
Yes. It’s your proof that the work was done: a dated report with photos, listing the work and any areas we couldn’t reach.
What happens to the dirty filters?
We do. Used filters go with us to be cleaned and the clean set stays in the canopy.
What if parts of the system cannot be reached?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, which we can install.
Which accreditations do you hold?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’re fully insured and have been trading since 2009.

- The site address and the type of premises

What a clean will not put right
We’d rather tell you now than book work that won’t help, so these are the things it won’t cover:
- Greasy ducts and risers that a filter change won’t reach
- 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 give us a ring on 0345 646 2711 or drop us a line and we’ll tell you honestly before booking.
Where we work
- School and hospital kitchens
- Baffle filters
- Island canopies
- Restaurants and pubs
- Mesh filters
- Wall canopies
Leave it or put it right?
Leaving filters too long pushes more grease into the plenum and ducts. That makes the next full clean a bigger job, and grease may build up faster than the cleaning interval allows. Booking ahead lets us plan the trip to Greatness at a time that suits you.
What you pay reflects the actual work. That is why we survey first, from photos or on site, and why the quote is fixed before any work starts.
