What affects the cost of grease filter exchange
There’s no set price list, because sites vary so much. The quote depends on:
- Travel, parking and unloading
- Whether it’s a one-off visit or part of a schedule
- Any permits to work or inductions
- The size of the system
Kitchens, offices, schools and hospitals are all priced 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 will go through it with you.
Helping us quote
To speed up the quote, please include:
- Wide photos of the system and the area around it
- Any previous report or certificate
- When the site is open and when it’s quiet
- Close-ups of filters, grilles, hatches or access panels
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. Then we send a fixed price so you know the cost before any work starts.
Grease filter exchange for kitchens and businesses in Toy's Hill
Think of filter exchange as routine care for the extract. It keeps airflow up and grease down between full cleans and takes a messy task off your team. Full TR19 cleaning still comes at the right interval, with a certificate. If you’re dealing with filters left unwashed on busy weeks and grease collecting in the filter channels, we can put it right.
Across London, many commercial kitchens are squeezed into basements and narrow back-of-house spaces, with extract ducts that can climb several floors to discharge at roof level. In Toy's Hill, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
Nothing is signed off by word of mouth: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Questions from Toy's Hill
Do you work overnight in Toy's Hill?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
Does London parking affect a job in Toy's Hill?
London parking can be tight, so details of loading bays and permits help. Night visits tend to make loading easier on London streets.
Which accreditations do you hold?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We’re fully insured and have been trading since 2009.
What happens to the dirty filters?
The greasy set leaves with us for cleaning, so your staff do not have to wash them. Clean filters go straight in.
Can you clean our existing filters instead?
Yes, that is an option. We’ll check your filters first, as damaged ones may be better replaced.
What do you do with what you remove?
It’s contained and taken away. We collect grease, debris and waste water as we go rather than letting it spread.
Do you have insurance?
Yes. Full insurance covers our work, and we have been trading since 2009.
Is TR19 cleaning required by law?
No. TR19® itself isn’t law; it’s a BESA specification. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.
Leave it or put it right?
Filters full of grease are fuel sitting right above the cooking. A flare-up on the range can reach them and grease in the duct can carry a fire further. Clean filters mean less fuel in the canopy. In Toy's Hill, as across London, ductwork often passes through shared risers and other people’s space.
Working hours, access and the scale of the site can all change the price. We take each of them into account, and the price is fixed before we start.

When to call us in Toy's Hill
Washing filters by hand doesn’t always get them clean. Grease lodges deep in baffles and mesh and a sink wash rarely reaches it.
These are the problems we see most often:
- Staff short of time to wash filters
- Grease filters clogged with grease
- Grease left in baffles after washing
- Smoke and heat lingering under the hood
Where a hall near Church of St Mary at South End of Village Green, or anywhere in Toy's Hill, hosts lunch clubs or events, its extract gathers grease just as a café’s does.
Questions to ask before booking
- Proof of accreditation you can verify
- Whether inaccessible sections are listed on the report
- When the next visit should be, and why
- How VAT is shown on the quote
Between visits
Think of this as the after-treatment advice, in brief:
- Keep filter exchange and TR19 cleaning on the same plan
- Wipe the outside of the canopy as part of daily cleaning
- Keep the extract on whenever the range is in use
- Make sure no filter is left out
Your next visit is scheduled before we leave. If cooking increases, we can change filters more often to match.
Saturated filters let more grease through. A regular cycle keeps the rest of the system cleaner between full cleans.
Different parts, different methods
Canopy filter housings
We check that filters sit snugly in the housing at each visit since a gap is a route for grease.
Baffle filters
Baffle filters are robust and widely used in commercial canopies. They still need regular cleaning as the collected grease builds up between the blades.
How the visit works
Night work is normal for us. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. The visit itself takes a few minutes per canopy, longer for a large kitchen with several canopies. Night and weekend working is normal for us in London, and a site in Toy's Hill is no exception.
- We look at the canopies and the condition of the filters.
- We note any filters that are bent, damaged or missing.
- We exchange the dirty filters for a clean set.
- The filters are checked for fit before we go.
- Anything that needs attention, such as a greasy plenum, is pointed out.
Before we arrive
- Let us know about permits to work or site inductions
- Find the previous report, if there is one
- Tell us the best time to work, such as after service or at a weekend

Advice
What grease filter exchange looks like in Toy's Hill
It’s Sevenoaks council that sends environmental health officers to food businesses in Toy's Hill. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Before-and-after pictures from each clean are a simple way to show the extract is in hand. In London, kitchens are normally cleaned overnight, when the kitchen is closed and loading is easier.
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Tandridge Priory is the nearest hospital to Toy's Hill, about 3.5 miles west. If your kitchen is in a listed or historic building, like the houses around Toy's Hill (Chartwell is about 1.1 miles west), fitting access panels needs care.
