Grease Filter Exchange in Swiss Cottage

- Drips falling from the filters onto equipment
Grease filter exchange in Swiss Cottage
Baffle filters and mesh filters both fill with grease. Clogged filters choke the airflow and the fan has to work harder. A steady cycle of clean filters keeps extraction strong. Common call-outs are for damaged filters letting grease past and weak extraction at the canopy, across school and hospital kitchens, baffle filters and island canopies.
Kitchens in Swiss Cottage, like many across London, can share a building with flats or offices, with the duct running up through shared risers. Grease in a duct like that is a fire risk to the whole building, not just the kitchen, which is why keeping it clean to TR19® matters.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

How the visit works
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool first, and the area around the work is covered and protected. The work itself takes less than an hour in most kitchens. Most London sites cannot stop for the day, so work in Swiss Cottage is typically done overnight, early in the morning or at weekends.
- We look at the canopies and the condition of the filters.
- Any damaged or missing filters are noted.
- We exchange the dirty filters for a clean set.
- The filters are checked for fit before we go.
- Anything that needs attention, such as a greasy plenum, is pointed out.
Before we arrive
- Find the previous report, if there is one
- Clear loose items from the work area
- Let us know how we reach the system, including roofs, risers and plant rooms

How the job changes from site to site
Canopy filter housings
Grease collects in the channels and drip trays below the filters. If it needs attention, we will tell you.
The plenum
Behind the filters sits the plenum, where air gathers before the duct. Grease that gets past the filters settles there.
What affects the quote in Swiss Cottage
Every site gets its own quote. These are the things that affect it:
- Whether it’s a one-off visit or part of a schedule
- Whether we need access equipment or extra panels
- Working hours and out-of-hours timing
- How big the system is
Kitchens, offices, schools and hospitals are all priced 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 explain each part.
What we need to know
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Detail shots of panels, filters and grilles
- Any symptoms, from odd noises to smells or leaks
- Any previous report or certificate
- Wide pictures of the system and the area around it

Questions from Swiss Cottage
Can you come to Swiss Cottage after we close?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. When you call 0345 646 2711, or email photos, mention when the site is quiet.
Is parking a problem for work in Swiss Cottage?
A loading bay, a visitor permit or off-street space near the site in Swiss Cottage makes the visit easier to plan. Working overnight, as we often do in London, typically makes it simpler.
What do you do to protect the area?
Protection goes down first: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
How often should grease filters be changed?
There’s no single answer. We look at your cooking and set an interval to match, and adjust it if needed.
Who has the legal duty for fire safety?
It depends on the building. The Fire Safety Order 2005 puts the duty on the responsible person, which may be the employer, owner, landlord, facilities manager or managing agent.
Can you clean our existing filters instead?
Yes. Some kitchens prefer their own filters cleaned on a schedule, and others prefer a straight swap. Either way, the canopy is not left without filters during service.
Does a filter exchange replace TR19 cleaning?
No. Filter exchange works between full cleans, not instead of them. TR19® cleaning covers the canopy, plenum, ductwork and fan and comes with a certificate and photo report.
What about areas you cannot get to?
Anything we can’t reach goes on the report, with pictures where possible, and we explain what access is needed, such as extra access panels in ductwork.
When something else is needed
Grease filter exchange cannot fix everything, and we’d rather say so up front. It doesn’t solve:
- Grease already built up in the ductwork, which needs a full TR19 clean
- Cooking smells reaching neighbours, which need odour control
- A heavily greased plenum or canopy, which needs cleaning to TR19
If in doubt, phone us on 0345 646 2711 or send us an email and we’ll say what we think.

What grease filter exchange looks like in Swiss Cottage
The FSA’s data shows about 74 pubs, bars and clubs and about 22 hotels and guest houses registered in Swiss Cottage and the streets around it, up to about 1.5 miles out. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Overnight is the normal time to clean a London kitchen extract, so trading is not affected. Swiss Cottage sits within the area of 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 The UCL Academy for example, are typically cleaned in the holidays so no lunches are lost. A hall kitchen that only cooks for events, whether near Church of All Souls or elsewhere in Swiss Cottage, still needs its extract cleaned, just less often.
Swiss Cottage is about 1 mile south of Hampstead, in Greater London. Anywhere in NW3, we can carry out grease filter exchange at your premises. Swiss Cottage is one of 764 towns, villages and districts in Greater London we cover for commercial clients.
Grease filter exchange in NW3, NW8 and NW6 follows the same survey, fixed quote and written report as everywhere else we cover. You will find streets such as Avenue Road, Acacia Road and Harben Road, and we cover them all for grease filter exchange. If your site is just outside Swiss Cottage, we cover South Hampstead (1 mile north), St John's Wood (1 mile south), Haverstock (1 mile east), Belsize Park (1 mile east) and Primrose Hill (1 mile east).

Local landmarks in Swiss Cottage
In Swiss Cottage, that means kitchens and buildings near Cafe Med pub, Holy Trinity CofE Primary School and Primrose Hill. Nearby too are Cecil Sharp House (1.1 miles east) and St. Mary's Town and Country School (less than half a mile north-east). There’s a railway station in Swiss Cottage itself: South Hampstead station. A little further out are Montfichet's Tower (3.7 miles south-east) and Isokon Gallery (0.8 miles north-east). The countryside around Swiss Cottage includes The Long Water and Primrose Hill.
Why act early in Swiss Cottage
Filters full of grease are fuel sitting right above the cooking. A flare-up on the range can reach them and grease in the duct can carry a fire further. Clean filters mean less fuel in the canopy. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account, and the price is fixed before we start.

Common problems we fix in Swiss Cottage
However long the kitchen cooks each day, the filters see every minute of it. A kitchen that cooks all day loads its filters quickly, so it needs more frequent changes.
It’s time to book a visit if you see:
- Filters so greasy the air can barely pass
- Weak extraction at the canopy
- Grease dripping from the canopy
- Filter washing that keeps being missed
Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Swiss Cottage is Hospital of St John and St Elizabeth, about 0.7 miles south.
What your quote should include

- Whether the whole system is included, or only the parts that are easy to reach
- If they look at the system before pricing
- How VAT is shown on the quote
What your team can do, and what needs us
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
