Grease filter exchange in Harrow Weald, done properly
Baffle filters and mesh filters both fill with grease. Once they’re clogged, airflow drops and the extract struggles. A steady cycle of clean filters keeps extraction strong. We are often asked to deal with poor airflow through the filters and damaged filters letting grease past, on mesh filters, baffle filters and island canopies.
London kitchens are often tucked into basements or the back of a building, and the duct may run up through several floors before it discharges at the roof. In Harrow Weald, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
Good records are part of the job. You get a written report with pictures after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Landlords, agents and facilities managers
When the building owner and the occupier are different, the lease normally sets out who maintains what. We are happy to deal with either side and send the paperwork to whoever needs it.
For anyone managing more than one site, we can schedule visits across all of them on one quote. Each site gets its own report and photos, so each one has its own record.
Staff cleaning versus specialist work
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.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
Common questions in Harrow Weald
Can parking be tricky for a job in Harrow Weald?
A loading bay, a visitor permit or off-street space near the site in Harrow Weald makes the visit easier to plan. If the building has a loading slot system, we’ll book into it.
Do you do school kitchen extract cleaning in Harrow Weald in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. Around Harrow Weald, the Food Standards Agency lists about 8 schools and colleges with registered kitchens within a mile and a half or so. You can ring 0345 646 2711, or send details by email with the dates the site is empty.
What is TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not law, but it’s the benchmark.
What if parts of the system can’t be reached?
They’re marked on the report. In ductwork, new access panels are often the answer, which we can install.
Do you look at the system first?
Yes. We always survey first, from your pictures and details, or with a visit where needed. Then you get a fixed quote.
What types of premises do you cover?
Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.
Do you recommend a next date?
Yes. The report recommends when the next visit should be, based on use and what we found.
Do you provide a certificate or report?
Yes. You get a written report with pictures after each visit, showing what was done, anything we couldn’t reach and when the next visit is due. Where the work is a TR19® Grease clean, there’s also a certificate issued through the BESCA Vent Hygiene Elite portal.
What happens on the day
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. The middle part takes longest, which takes well under an hour for most canopies. We fit London jobs around the building rather than the other way round, so a visit in Harrow Weald is usually out of hours.
- We record the number, size and type of your filters.
- We set the interval with you.
- On each visit, we remove the greasy filters.
- Clean filters go in and we check they sit snugly.
- The dirty filters leave with us and the next visit is booked.
Getting ready for the visit
- Mention any locked doors, roof access or ceiling voids
- Tell us the best time to work, such as after service or at a weekend
- Allow time for equipment near the work to be turned off and cool down
Getting a quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.

Looking after it afterwards
Once we’ve finished, these simple steps help:
- Always run the extract while cooking
- Wipe the outside of the canopy as part of daily cleaning
- Tell us if the menu or opening hours change
- Report a dripping canopy early
The canopy looks cleaner and the air moves better straight away. Always run the extract during cooking so the filters do their job.
If cooking has stepped up, the filter schedule should too. Changing the interval early stops grease building up unseen behind the canopy.
How the job changes from site to site
The plenum
Clean filters reduce the grease reaching the plenum, but it still needs cleaning as part of TR19.
Canopy filter housings
We check that filters sit snugly in the housing at each visit, because gaps let grease through.
When something else is needed
A few issues sit outside what this work can do:
- Cooking smells reaching neighbours, which need odour control
- A heavily greased plenum or canopy, which needs cleaning to TR19
- A canopy that does not capture the vapour properly
If you are not sure, just phone us on 0345 646 2711 or drop us a line and we will give you a straight answer before booking.

Harrow Weald kitchens: local notes
The FSA’s food hygiene register shows about 99 restaurants, cafés and canteens and about 45 takeaways within about 1.5 miles of central Harrow Weald. Any of those kitchens with a canopy relies on its filters to catch grease before it reaches the duct. Night work suits London kitchens, and roads and loading bays tend to be quieter too. Kitchens in Harrow Weald get their food hygiene inspections from Harrow council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A dated certificate in the maintenance file answers the question before it’s asked.
If you run catering at a healthcare site, such as a hospital like Northwick Park Hospital about 2.1 miles south, the extract may need cleaning more often than a part-time kitchen. Where a hall near St Michael & All Angels, or anywhere in Harrow Weald, hosts lunch clubs or events, its extract gathers grease just as a café’s does. Term dates shape school work: for a school like Salvatorian Roman Catholic College, an extract clean fits neatly into a half-term or summer break.
