Grease Filter Exchange in Kingston upon Thames
Grease filter exchange for Kingston upon Thames, from a team that has been trading since 2009. Out-of-hours visits and 24/7 emergency callout.
- A canopy that drips grease
- Filter washing that keeps being missed
- Filters that leave gaps in the canopy
Common problems we fix in Kingston upon Thames
Every fry, grill and sauté sends grease-laden vapour upwards. Much of it is trapped by the filters, and day by day they load up and airflow falls away.
Signs it’s time to call us include:
- Staff short of time to wash filters
- Weak extraction at the canopy
- Filters that come out of the sink still dirty
- Drips falling from the filters onto equipment
Volunteers running a hall kitchen near Church of St Luke, or anywhere in Kingston upon Thames, may not know when the extract was last cleaned, and a grease test settles it.

Grease filter exchange in Kingston upon Thames
Filter exchange sits between full TR19® cleans. Fresh filters help limit what gets into the ductwork, but some grease still passes through as vapour. So the canopy, plenum and ducts still need their full TR19 clean. The work covers mesh filters, wall canopies and island canopies, and common reasons people get in touch are poor airflow through the filters and grease collecting in the filter channels.
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. For a kitchen in Kingston upon Thames, that usually means a longer system to clean and more access panels to plan around.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Keeping the system healthy
How long the results last depends on use and care. We suggest:
- Never cook with the extract switched off
- Book full TR19 cleans alongside filter changes
- Keep every filter in place during service
- Let us know if your cooking hours increase
Nothing changes for your staff, except one less greasy job. Make sure we can reach the canopy on exchange day and let us know of any changes to opening hours.
If filters are already dripping, they’re overdue. Changing them now reduces the fuel above the cooking, and it’s worth checking the plenum too.
Leave it or put it right?
Leaving filters too long pushes more grease into the plenum and ducts. The ductwork then loads up faster, and grease may build up faster than the cleaning interval allows. Planning ahead in Kingston upon Thames lets you pick a quiet night rather than lose a busy one.
The cost depends on the size of the system, the condition it’s in and access to every part of it. We give you a fixed price before we start, so you know where you stand.

Kingston upon Thames kitchens: local notes
Food Standards Agency records include about 48 pubs, bars and clubs and about 7 hotels, B&Bs and guest houses in and around Kingston upon Thames, up to about a mile and a half out. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Kingston upon Thames is covered by London Fire Brigade. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. Overnight is the normal time to clean a London kitchen extract, so trading isn’t affected.
If you run catering at a healthcare site, such as a hospital like Kingston Hospital about 0.7 miles east, the extract may need cleaning more often than a part-time kitchen. Commuter trade near Kingston station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands.

Staff cleaning versus specialist work
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.

Yes. Send the list of sites and the work at each and we’ll quote them together.
How much does a filter exchange service cost?

A bent filter leaves a gap for grease. We flag any we find so they can be replaced.
