Grease filter exchange for kitchens and businesses in Netherne on-the-Hill
Whether your canopy has baffle or mesh filters, they load up with grease. Once they’re clogged, airflow drops and the extract struggles. Regular exchange keeps the air moving. Common call-outs are for a greasy plenum behind the filters and poor airflow through the filters, on restaurants and pubs, mesh filters and school and hospital kitchens.
Kitchens in Netherne on-the-Hill, 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.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

Staff cleaning versus specialist work
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
Looking after it afterwards
Results last longer with the right care. Here’s what we suggest:
- Always run the extract while cooking
- Wipe the outside of the canopy as part of daily cleaning
- Don’t refit a filter that’s bent
- Mention it if the kitchen gets busier
Between visits, check that every filter is still in place. A missing filter leaves a gap for grease, so let us know if one goes missing or gets damaged.
Clean filters plus regular full cleans keep the system in good health. Setting both up on a schedule means neither slips.

Kitchen extracts in Netherne on-the-Hill
Look up Netherne on-the-Hill on the FSA’s food hygiene register and you’ll find about 4 cafés, restaurants and staff canteens and about 3 takeaways within roughly a mile and a half of the centre of Netherne on-the-Hill. Any of those kitchens with a canopy relies on its filters to catch grease before it reaches the duct. Most London extract cleaning happens at night, after the last service. London Fire Brigade covers Netherne on-the-Hill. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
Bursars and site managers at schools such as Coulsdon Sixth Form College tend to book extract cleaning for when the kitchen is empty. Volunteers running a hall kitchen near Church of St Margaret, or anywhere in Netherne on-the-Hill, may not know when the extract was last cleaned, and a grease test settles it. Healthcare kitchens, like those at hospitals such as St Lawrence's Hospital (about 1.9 miles east), often cook for long hours, which puts them in BESA’s heavier-use bands.

How the job changes from site to site
Baffle filters
In a baffle filter, the air zigzags through metal baffles. Grease is thrown out of the airstream and collects on the baffles.
Busy restaurant and pub kitchens
Heavy cooking means more grease reaching every part of the system. Changing them on time protects the ducts behind.
Honest limits
Grease filter exchange can’t fix everything, and we’ll tell you before any work starts. It won’t put right:
- Odours from the discharge that filters will not stop
- A heavily greased plenum or canopy, which needs cleaning to TR19
- Grease already built up in the ductwork, which needs a full TR19 clean
If you’re not sure, just ring 0345 646 2711 or drop us a line and we will give you a straight answer.
What the work covers
- Baffle filters
- Restaurants and pubs
- Mesh filters
- Island canopies
- School and hospital kitchens
- Wall canopies
Managing agents and facilities teams in Netherne on-the-Hill
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.
Whether it’s one building or many, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
What we do, step by step
At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. The visit takes well under an hour for most canopies. Getting kit into a London building takes planning, so let us know where we can load and park in Netherne on-the-Hill.
- We start by noting how many filters you have and what type they are.
- We agree a schedule that suits how much the kitchen cooks.
- On each visit, the dirty filters come out of the canopy.
- We fit clean filters and check they sit snugly in the housing.
- If a filter is damaged or the plenum needs attention, we tell you.
Before we arrive
- Mention any locked doors, roof access or ceiling voids
- Tell us about site rules, permits or sign-in
- Arrange a key holder or contact on site
Getting a quote
To help us quote: the address, the type of site and when it’s open, pictures of the system and any previous report or certificate. Then ring 0345 646 2711 or email us.

How we price grease filter exchange
The price is fixed before any work begins. It takes into account:
- Whether several sites go on one quote
- Where the site is and how we reach it
- Working hours and out-of-hours timing
- Access, including roofs, risers and ceiling voids
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re unsure, give us a ring on 0345 646 2711 or drop us a line for straight advice and a fixed quote.
Asking for a quote
When you call or email, these details help:
- Where the site is and what kind of site it is
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Your opening hours and when the area is out of use
- Any access panels or hatches you can see
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
