Highgate grease filter exchange
Our technicians work in Highgate on a scheduled grease filter exchange, swapping dirty canopy filters for clean ones. Fixed quotes, work around your opening hours and photo reports on every job.
- Filters that leave gaps in the canopy
- Grease filters clogged with grease
- Filters left unwashed on busy weeks
What happens on the day
There are three stages on the day: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. The middle part takes longest, and that takes a few minutes per canopy, longer for a large kitchen with several canopies. Expect the work in Highgate to happen after your last customer leaves, not during trading.
- We start by noting how many filters you have and what type they are.
- A change schedule is agreed to match the kitchen’s cooking hours.
- At each visit, the greasy filters are lifted out.
- We fit clean filters and check they sit snugly in the housing.
- Anything we notice, such as bent filters or a dirty plenum, is pointed out.
Getting ready for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Find the previous report, if there is one
- Allow time for equipment near the work to be turned off and cool down

Grease filter exchange for kitchens and businesses in Highgate
Baffle filters and mesh filters both fill with grease. Clogged filters choke the airflow and the extract struggles. Regular exchange keeps the air moving. Typical jobs include filters left unwashed on busy weeks and a canopy running with filters missing, on baffle filters, mesh filters and school and hospital kitchens.
In London, few kitchens can spare a day to close, so work in Highgate is normally booked for the night or the early hours. Before the clean, we agree loading, parking and roof access with whoever manages the building.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Keeping the system healthy
Aftercare is simple, and it makes the next visit easier:
- Tell us if a filter is bent or damaged
- Never cook with the extract switched off
- Keep every filter in place during service
- Don’t let the full clean slip because filters are changed
Fresh filters improve airflow at the canopy from the moment they’re fitted. Always run the extract during cooking so the filters do their job.
A kitchen that is getting busier needs its filters changed more often. Adjusting the schedule now prevents a build-up behind the canopy.
What a clean won’t put right
We’ll always give you a straight diagnosis, so here’s what grease filter exchange won’t do:
- Grease deep in the extract system
- A fan that is failing or too weak for the system
- Grease behind the filters that a swap cannot remove
Not sure which it is? You can call 0345 646 2711 or email us and we will tell you honestly before booking.

Grease filter exchange in Highgate: the local picture
The FSA’s food hygiene register shows about 319 restaurants, cafés and canteens and about 82 sandwich bars and takeaways within 1.5 miles or so of the middle of Highgate. Each canopy among them has filters that load with grease and need swapping or cleaning. Food hygiene inspections in Highgate are the job of Haringey council’s environmental health team. 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. In London, kitchens are usually cleaned overnight, when the kitchen is closed and loading is easier.
Church and community hall kitchens, near Highgate United Reformed Church or anywhere around Highgate, are easy to forget, but their extracts collect grease like any other. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Highgate Private Hospital is the nearest hospital to Highgate, about 0.6 miles north-west. Commuter trade near Upper Holloway station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands.

Why it’s worth doing now in Highgate
Some kitchens in Highgate wash filters themselves to save the cost of a service, and it works when it’s done well and never skipped. When it doesn’t happen reliably, an exchange makes it automatic. Planning ahead in Highgate lets you pick a quiet night rather than lose a busy one.
What you pay reflects the actual work. That’s why every job is surveyed first, and the price is agreed before any work starts.

Common questions in Highgate
Can school kitchens in Highgate be cleaned in the holidays?
Yes. Half-terms and the summer break are the natural time for school work. Around Highgate, the Food Standards Agency lists about 34 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we’ll book the visit for when the site is empty.
What do you need to know about parking in Highgate?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Night visits tend to make loading easier on London streets.
How much does a filter exchange service cost?
The cost depends on your filters and the schedule. Just ring 0345 646 2711 or send us an email for a fixed quote, normally within one working day.
What types of premises do you cover?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
Can damaged filters stay in the canopy?
A badly damaged filter should be replaced. We’ll tell you which ones and why on the visit.
How long does the visit take?
It depends on the size of the system, but for many sites it takes well under an hour for most canopies. We’ll give you a better idea when we quote.
Does a filter exchange disrupt service?
Not for long, and we can time it to avoid service. Cooking shouldn’t happen with the filters out so the swap is done promptly.
How much notice do you need?
For planned work, earlier is better, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
Multi-site and managed buildings
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
Facilities teams in offices, schools and healthcare sites book us too across Greater London. Larger estates can be phased building by building around the people who use them.
What your team can do, and what needs us
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Different parts, different methods
The plenum
Clean filters reduce the grease reaching the plenum, but it still needs cleaning as part of TR19.
Mesh filters
Mesh traps grease between its layers, which makes hand-washing hard work.
