What affects the quote in Whetstone
We quote each job individually. This is what makes a difference:
- The scale of the work
- Site requirements such as sign-in and permits
- The number of sites or systems
- Travel, parking and unloading
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll go through it with you.
Asking for a quote
Photos let us diagnose from a distance. Try to include:
- Any previous report or certificate
- Detail shots of panels, filters and grilles
- How we’d reach plant on a roof or in a plant room
- The times we could work without disrupting the site
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.
About our grease filter exchange in Whetstone
The filters in the canopy are the first thing cooking vapour meets. Their job is to stop grease getting further into the system and they do it best when they’re clean. With grease filter exchange, clean filters replace greasy ones at regular intervals. If you are dealing with filters that leave gaps in the canopy and poor airflow through the filters, we can put it right.
London kitchens tend to trade late and open early, so extract cleaning in Whetstone is typically done overnight, after the last service. Parking, loading and access to the roof are agreed with the building before the night of the clean.
Each visit ends with a written report and pictures, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

What we are called out for in Whetstone
Washing filters by hand does not always get them clean. Grease hides in the folds of a baffle or the layers of a mesh and a sink wash rarely reaches it.
Clients usually contact us after spotting something like this:
- Damaged filters letting grease past
- A greasy plenum behind the filters
- A canopy that drips grease
- Grease filters clogged with grease
If you look after a school kitchen, at a school such as Queenswell Infant & Nursery School or anywhere near Whetstone, the holidays are the usual time for a TR19® clean.

What the work involves, part by part
School, care home and staff kitchens
Even kitchens with fixed meal times build up grease, though often more slowly.
Busy restaurant and pub kitchens
Heavy cooking means more grease reaching every part of the system. Regular changes help protect the ductwork.
Kitchen extracts in Whetstone
Food Standards Agency records include about 31 pubs and bars within roughly a mile and a half of the centre of Whetstone. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. The fire and rescue service for Whetstone is 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. It’s Barnet council that sends environmental health officers to food businesses in Whetstone. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
For kitchens close to Oakleigh Park station, where the day often starts early and ends late, the extract can be cleaned overnight. Church and community hall kitchens, near Church of St John or anywhere around Whetstone, are easy to forget, but their extracts collect grease like any other.

The process
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. The visit itself takes well under an hour for most canopies. Night and weekend working is normal for us in London, and a site in Whetstone is no exception.
- We count and measure the filters in every canopy.
- A change schedule is agreed to match the kitchen’s cooking hours.
- Each visit starts with the used filters being removed.
- Clean, dry filters are fitted in their place, with no gaps left between them.
- If a filter is damaged or the plenum needs attention, we tell you.
Getting ready for the visit
- Dig out any earlier paperwork for the system
- Mention any parking or loading restrictions
- Plan for cooking equipment or plant to be off before we arrive
Getting a quote
Here’s what helps us quote: the address, the type of site and when it’s open, photos of the system and any previous report or certificate. Once you have those, phone us on 0345 646 2711 or drop us a line.

Between visits
Here’s the after-treatment advice, in brief:
- Look out for drips from the canopy
- Never cook with the extract switched off
- Keep filter exchange and TR19 cleaning on the same plan
- Wipe the outside of the canopy as part of daily cleaning
The canopy looks cleaner and the air moves better right away. Always run the extract during cooking so they catch grease as intended.
Filter exchange and TR19 cleaning work best together. Setting both up on a schedule keeps everything on track.

What else we do in Whetstone
Questions from Whetstone
Does London parking affect a job in Whetstone?
A loading bay, a visitor permit or off-street space near the site in Whetstone makes the visit easier to plan. Working overnight, as we often do in London, usually makes it simpler.
Do you work at weekends in Whetstone?
Yes, out-of-hours work is a big part of what we do. That way a site in Whetstone doesn’t have to lose a day’s trading. Your opening times are the first thing we ask for.
What about areas you cannot get to?
They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, along with a quote to put access in.
How long does grease filter exchange take?
The work itself takes anything from a few minutes to an hour or so, depending on the number of filters. Bigger or more complicated systems take longer, and the quote will say how long.
What does TR19 mean?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Is Whetstone in your area?
Yes. We cover Whetstone and across Greater London, as part of our work across South East England and London. For a fixed quote, call 0345 646 2711, or send details by email.
Do you offer emergency callouts?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we will advise on what to do next.
How far ahead should we book?
Earlier is better, particularly for night and weekend visits. We normally quote within one working day, and emergencies are covered by our 24/7 line.
What your team can do, and what needs us
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
What grease filter exchange cannot fix
We will always give you a straight diagnosis, so here’s what grease filter exchange will not do:
- Grease behind the filters that a swap cannot remove
- Odours from the discharge that filters won’t stop
- A canopy that doesn’t capture the vapour properly
If in doubt, call 0345 646 2711, or email photos and we’ll say what we think before booking.
