Canonbury grease filter exchange
Our technicians work in Canonbury on grease filter exchange. Out-of-hours visits, a fixed quote and a written report with photos on every job.
- Filters left unwashed on busy weeks
- Gaps where filters have been removed
- Filters that leave gaps in the canopy
Different parts, different methods
School, care home and staff kitchens
Even kitchens with fixed meal times build up grease though normally at a gentler pace.
Busy restaurant and pub kitchens
The more a kitchen cooks, the more grease the filters see. Regular changes help protect the ductwork.
Grease filter exchange in Canonbury, done properly
In Canonbury, our filter exchange runs on a schedule set by how much the kitchen cooks. Busy kitchens need changes more often, lighter ones less. We agree the interval with you at the start. Common call-outs are for gaps where filters have been removed and a canopy that drips grease, across school and hospital kitchens, wall canopies and baffle filters.
In London, few kitchens can spare a day to close, so extract cleaning in Canonbury is normally done overnight, after the last service. Parking, loading and access to the roof are agreed with the building before the night of the clean.
It’s worth checking any contractor’s accreditations. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

Canonbury: your questions answered
Do you work overnight in Canonbury?
Yes, out-of-hours work is a big part of what we do. It means the site in Canonbury keeps running as normal. Your opening times are the first thing we ask for.
Who enforces fire safety at workplaces in Canonbury?
It’s London Fire Brigade, which covers Canonbury. TR19® is not law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Do we lose a day’s trading?
Not usually. We need the work area to ourselves while we are on site, so the visit goes in a quiet slot.
Do you cover Canonbury?
Yes. We work in Canonbury and across Greater London, within our South East and London area. To book, give us a ring on 0345 646 2711 or email us.
Can you come out in an emergency?
Yes. Our emergency line runs 24/7 for anything that can’t wait until a planned visit. Ring any time and tell us what’s happened.
What if some of our filters are damaged?
A badly damaged filter should be replaced. We’ll tell you which ones and why on the visit.
What happens if you can’t reach some of it?
They’re listed in the report, never skipped quietly. You will know exactly which parts weren’t reached and why, along with a quote to put access in.
Do you recommend a next date?
Yes. We put a recommended next date on the report. BESA’s minimum intervals for kitchen extracts range from 3-monthly for heavy use to 12-monthly for light use, and fire dampers need testing at least once a year.
What affects the cost of grease filter exchange
You’ll get a fixed price before we start. It takes into account:
- Any permits to work or inductions
- The condition we find in the survey
- Whether we need access equipment or extra panels
- Where the site is and how we reach it
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote and give you a fixed price before we start.
Asking for a quote
Photos and a few facts are often enough to price the work. Useful things to send:
- Problems your staff have spotted
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The times we could work without disrupting the site
- Close-ups of filters, grilles, hatches or access panels
For grease filter exchange in Canonbury, ring 0345 646 2711, or email photos. Tell us what kind of premises it is and when it’s open, plus pictures or the previous report if they’re to hand. A fixed quote normally follows within one working day.
Kitchen extracts in Canonbury
The FSA’s food hygiene register shows about 1,209 cafés, restaurants and staff canteens and about 277 takeaways and sandwich shops in and around Canonbury, 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. London Fire Brigade covers Canonbury. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. In London, kitchens are usually cleaned overnight, when the kitchen is closed and loading is easier.
If you cook for passing trade around Canonbury station, the extract can be cleaned between your last and first customer. Where a hall near St Paul's Church, or anywhere in Canonbury, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

Signs you need grease filter exchange in Canonbury
Missing filters are more common than you’d think. Every gap in the filter bank lets grease straight into the plenum and on into the ductwork.
Clients typically contact us after spotting one of these:
- A canopy that drips grease
- Gaps where filters have been removed
- Grease collecting in the filter channels
- Blocked baffle filters
If you run catering at a historic house or estate in the area (Sutton House is about 1.7 miles east), event kitchens in older buildings often have awkward duct runs that need planning.
Questions to ask before booking
- If they look at the system before pricing
- Whether the quote shows VAT
- Whether the price is fixed
- What hours they’ll be on site
For landlords and multi-site operators
We regularly work with managing agents. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
Honest limits
Grease filter exchange can’t fix everything, and we’d rather say so up front. It will not put right:
- Greasy ducts and risers that a filter change won’t reach
- An extract that was undersized from the start
- Grease behind the filters that a swap cannot remove
If in doubt, give us a ring on 0345 646 2711 or email us and we’ll say what we think.

- Any damaged or missing filters are noted.
- We exchange the dirty filters for a clean set.
- We check the filters are seated and the canopy is ready to use.

What your team can do, and what needs us
When your team notices a problem 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’ll take a look and give you a fixed quote.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
