Grease filter exchange in Kennington
A filter service works alongside TR19® cleaning, not instead of it. Fresh filters help limit what gets into the ductwork though vapour still carries some grease past them. That is why the whole system still needs cleaning to TR19 at the right interval. The work covers school and hospital kitchens, island canopies and wall canopies, and common reasons people get in touch are filters so greasy the air can barely pass and staff short of time to wash filters.
In a London area like Kennington, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. A duct fire there can reach parts of the building far from the range, so a regular TR19® clean protects everyone in it.
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 are fully insured.

For landlords and multi-site operators
Whether it’s one building or many, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We are happy to deal with either side, and the report can go to both.
Signs you need grease filter exchange in Kennington
What a kitchen cooks affects how fast filters clog. Fryers, grills and woks load filters faster than ovens and steamers, so the right exchange interval varies.
Most sites get in touch when they notice one of these:
- A greasy plenum behind the filters
- Filters that come out of the sink still dirty
- Filter washing that keeps being missed
- Bent or damaged filters that do not sit properly
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; The Gordon Hospital is the nearest hospital to Kennington, about 1 mile north-west.

FAQs for Kennington
Do you clean school canteen extracts around Kennington out of term?
Yes. Half-terms and the summer break are the natural time for school work. Food Standards Agency records list about 109 schools, colleges and universities with registered kitchens within about a mile and a half of Kennington. Send us your term dates when you phone us on 0345 646 2711 or send us an email, and we will fit the work in.
Who carries out food hygiene inspections in Kennington?
Food hygiene inspections in Kennington are carried out by Lambeth council. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Is filter exchange enough instead of a full extract clean?
No. Clean filters help keep grease down, but the ducts and plenum still need cleaning at the right interval.
Do you have insurance?
Yes. Duct Doctor is fully insured, and the details are available on request.
Do you handle baffle and mesh filters?
Baffle filters and mesh filters. Tell us what you have when you give us a ring on 0345 646 2711 or send us an email and we’ll confirm it on site.
Is Kennington in your area?
Yes. We work in Kennington and the rest of Greater London, as part of our work across South East England and London. For a fixed quote, ring 0345 646 2711 or email us.
Do you deal with bent or broken filters?
We check every filter at each visit. Any that are bent or damaged are flagged since a poor fit lets grease past.
Do you work with multi-site operators?
Yes. We work across South East England and London, so sites at different addresses can be planned together on one programme. Each site gets its own report and pictures.
In-house cleaning or a specialist?
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 will take a look and send you a fixed quote.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
What affects the cost of grease filter exchange
Before we fix a price, we need to know a few things. We look at:
- The scale of the work
- Any permits to work or inductions
- Whether several sites go on one quote
- The condition we find in the survey
What you pay depends on how big the system is, what state it’s in and access to every part of it. You get a fixed price before any work starts, so there are no surprises.
What to send for a quote
When you contact us, these details help:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The roof, plant room or outside wall the system runs to
- A few general shots of the system
- When the site is open and when it’s quiet
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.

Aftercare tips
Results last longer with the right care. Here’s what we suggest:
- Book full TR19 cleans alongside filter changes
- Report a dripping canopy early
- Do not refit a filter that is bent
- Mention it if the kitchen gets busier
We tell you if we spot anything in the canopy that needs attention. It can be a sign that a full TR19® clean is due, and we can arrange it.
Dripping filters are a clear sign they’re full. A clean set right away cuts the grease in the canopy and the plenum may need a clean as well.
When it’s something else
We will always give you a straight diagnosis, so here’s what grease filter exchange won’t do:
- Extraction problems caused by the fan rather than the filters
- An extract that was undersized from the start
- Cooking smells reaching neighbours, which need odour control
If you are not sure, just give us a ring on 0345 646 2711 or drop us a line and we’ll give you a straight answer before you book.

Grease filter exchange in Kennington: the local picture
Food Standards Agency records list about 1,129 restaurants, cafés and works canteens and about 372 takeaways and sandwich shops in and around Kennington, up to about a mile and a half out. Any of those kitchens with a canopy relies on its filters to catch grease before it reaches the duct. Kitchens in Kennington get their food hygiene inspections from Lambeth council. Extraction counts as kitchen equipment, so its condition can come up on the day. Keeping each certificate and photo report on file helps show the extract is looked after. Fire safety in Kennington falls to London Fire Brigade. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
School kitchens, at schools like St Stephen's Church of England Primary School for example, are normally cleaned in the holidays so no lunches are lost. If you cook for passing trade around Vauxhall station, the extract can be cleaned between your last and first customer.
