- Gaps where filters have been removed
- A canopy that drips grease
- Poor airflow through the filters
What the work involves, part by part
Busy restaurant and pub kitchens
High-output kitchens clog filters quickly. They often need the shortest exchange interval.
The plenum
Behind the filters sits the plenum, where air gathers before the duct. It collects whatever grease the filters miss.
Grease filter exchange in North Harrow
A filter that doesn’t sit right lets grease straight past. Gaps in the filter bank are a direct route into the plenum and every filter is checked when we swap them. Damaged filters are flagged so they can be replaced. Common call-outs are for filters that leave gaps in the canopy and filter washing that keeps being missed, across mesh filters, island canopies and baffle filters.
Kitchens in North Harrow, 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.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What grease filter exchange looks like in North Harrow
Food Standards Agency records include about 25 pubs, bars and clubs and about 4 hotels, B&Bs and guest houses within roughly a mile and a half of the centre of North Harrow. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Environmental health officers from Harrow council inspect food businesses in North Harrow. Extraction counts as kitchen equipment, so its condition can come up on the day. Our report lists what was cleaned and when, which is useful to have ready. North Harrow is covered by London Fire Brigade. 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.
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Headstone Manor is about 0.8 miles north-east), access may need planning. Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to North Harrow is Northwick Park Hospital, about 1.9 miles east.

What else we do in North Harrow
Signs you need grease filter exchange in North Harrow
Missing filters are more common than you’d think. A missing filter leaves an open route into the system and on into the ductwork.
Any of these means the system needs a check-up:
- A canopy that drips grease
- Weak extraction at the canopy
- Grease left in baffles after washing
- A greasy plenum behind the filters
Volunteers running a hall kitchen near Church of St Alban, or anywhere in North Harrow, may not know when the extract was last cleaned, and a grease test settles it.
What your quote should include
- Whether the whole system is included, or only the parts that are easy to reach
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- When the next visit should be, and why
- What hours they’ll be on site
What we do, step by step
The visit has three parts: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with pictures. Most of the time goes on the work itself, which takes a few minutes per canopy, longer for a large kitchen with several canopies. Expect the work in North Harrow to happen after your last customer leaves, not during trading.
- First, we check the canopies and the filters in them.
- We note any filters that are bent, damaged or missing.
- 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
- Have your last certificate or report to hand
- Name a contact who can let us in at the agreed time
- Tell us the best time to work, such as after service or at a weekend

Related advice
Why deal with it now?
Dripping canopies and greasy smells often start with the filters. Drips land on surfaces and equipment below and that is the kind of thing inspectors look for. Every month a London system goes without attention adds to what has to be done later.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you are unsure, phone us on 0345 646 2711 or drop us a line and we’ll give you an honest view and a fixed quote.
Why North Harrow businesses choose us
- One contact for all your sites in London and the South East
- A written report with pictures after every visit
- A BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease
- Ventilation hygiene specialists since 2009
Keeping the system healthy
Aftercare is simple, and it makes the next visit easier:
- Mention it if the kitchen gets busier
- Report damaged filters so they can be replaced
- Report a dripping canopy early
- Book full TR19 cleans alongside filter changes
Keep an eye out for filters that have been taken out. Gaps let grease into the plenum, so let us know if one goes missing or gets damaged.
If filters are already dripping, they’re overdue. A clean set right away cuts the grease in the canopy and the plenum may need a clean as well.
What staff can safely do
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
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.
FAQs for North Harrow
Who enforces fire safety at workplaces in North Harrow?
That’s London Fire Brigade. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Do you clean school canteen extracts around North Harrow out of term?
Yes. Half-terms and the summer break are the natural time for school work. With about 15 schools and colleges on the FSA’s register within roughly a mile and a half of North Harrow, it pays to plan holiday dates ahead. You can call us on 0345 646 2711 or use the quote form with the dates the site is empty.
Do you survey before quoting?
Yes. Every job is surveyed first, from your photos and details, or with a visit where necessary. Then you get a fixed quote.
What do you do with what you remove?
We take it away when we go. During the work, it’s contained to keep the area clean.
Do you work with multi-site operators?
Yes. Our area covers London and the South East, so we can schedule a run of sites on one programme. Each site gets its own report and pictures.
What types of filter do you exchange?
We work with both baffle and mesh filters. We check what’s in your canopies first and plan the exchange around them.
Do you take the used filters away?
We take them away to be cleaned, so your staff don’t have to wash them. A clean set is fitted in their place.
Do we need to close the kitchen while filters are changed?
Not for long, and we can time it to avoid service. The canopy shouldn’t be used without filters so the swap is done promptly.
When it’s something else
A few issues sit outside what this work can do:
- A canopy too small for the cooking beneath it
- A fan that is failing or too weak for the system
- Grease deep in the extract system
If in doubt, give us a ring on 0345 646 2711, or email photos and we will say what we think before you book.
