Grease filter exchange in Crossness, Greater London
Grease filter exchange for Crossness, from a team that has been trading since 2009. Out-of-hours visits and 24/7 emergency callout.
- Hand-washed filters that still look greasy
- Gaps where filters have been removed
- Grease building up behind the canopy filters
Looking after it afterwards
Here’s the after-treatment advice, in brief:
- Keep the canopy clear for exchange visits
- Clean the canopy surfaces regularly
- Make sure no filter is left out
- Mention it if the kitchen gets busier
If the plenum behind the filters looks greasy, we say so. It can be a sign that a full TR19® clean is due and we can book that in.
Saturated filters let more grease through. A regular cycle keeps the rest of the system cleaner until the next TR19 clean.
How we handle grease filter exchange in Crossness
Filter exchange sits between full TR19® cleans. Clean filters reduce the grease reaching the ducts, but some grease still passes through as vapour. That is why the whole system still needs cleaning to TR19 at the right interval. If you’re dealing with filters that leave gaps in the canopy and gaps where filters have been removed, we can put it right.
In a London area like Crossness, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. 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.
The sign-off is always in writing: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Grease, kitchens and Crossness
The Food Standards Agency lists about 10 bars, pubs and nightclubs as registered food businesses in and around Crossness, up to about a mile and a half out. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. In Crossness, food businesses are inspected by environmental health officers from Bexley council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A TR19® certificate and photo report after each clean gives you a record to show an inspector. London jobs usually start after the last service, with loading and roof access agreed with the building first.
If you run catering at a healthcare site, such as a hospital like Erith and District Hospital about 2.1 miles south-east, the extract may need cleaning more often than a part-time kitchen. Commuter trade near Abbey Wood station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands.
Crossness is about 2 miles north-west of Erith, in Greater London. From the centre of Crossness to the outskirts, grease filter exchange is available to all kinds of commercial premises, from a single unit to a large public building.

How the visit works
The first job on site is protection: floors, worktops and anything near the work are covered. Then we make the system safe and start. The work on site takes less than an hour in most kitchens, and the area is cleaned down before we leave. In Crossness, as across London, we normally work overnight or at weekends and hand the site back ready to open.
- 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.
- Clean, dry filters are fitted in their place, with no gaps left between them.
- If a filter is damaged or the plenum needs attention, we tell you.
How to prepare

Advice
How we price grease filter exchange
We quote each job individually. These are the things that affect it:
- Site requirements such as sign-in and permits
- Access, including roofs, risers and ceiling voids
- Travel, parking and unloading
- What state the system is in
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. You will have a fixed price before any work starts.
What we need to know
The more you tell us, the more accurate the quote. With your enquiry, please include:
- Wide photos of the system and the area around it
- Your last certificate, test record or report
- The postcode and the type of business
- Any symptoms, from odd noises to smells or leaks
To get a fixed quote, call 0345 646 2711 or send us an email with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. We typically come back within one working day.
When to call us in Crossness
Filters get bent and damaged with handling. A bent filter does not seat properly, leaving gaps for grease to slip through.
Look out for any of the following:
- Filters left unwashed on busy weeks
- Filters that leave gaps in the canopy
- Hand-washed filters that still look greasy
- Weak extraction at the canopy
For schools such as St John Fisher Catholic Primary School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed.
What your quote should include
- Proof of insurance
- Whether inaccessible sections are listed on the report
- What paperwork you get at the end
- Whether the whole system is included, or only the parts that are easy to reach
Questions from Crossness
Do you work overnight in Crossness?
Yes, nights and weekends are routine for us. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
Who enforces fire safety at workplaces in Crossness?
That is London Fire Brigade. TR19® isn’t law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
How much does a filter exchange service cost?
Every kitchen is different, so we quote once we know your filters and schedule. We send you a fixed quote before the first visit.
Do you handle baffle and mesh filters?
We work with both baffle and mesh filters. We check what’s in your canopies first and plan the exchange around them.
What happens if you cannot reach some of it?
The report shows them clearly. In ductwork, new access panels are often the answer, and we can fit those.
Do you offer maintenance contracts?
Yes. Tell us what you have and how it’s used, and we’ll suggest a schedule and quote for it.
What is TR19?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Which accreditations do you hold?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We have been trading since 2009 and we are fully insured.
For landlords and multi-site operators
Facilities teams in offices, schools and healthcare sites book us too in Crossness and across Greater London. Work can be phased by floor, building or site around the people who use them.
If you look after several sites, we can schedule visits across all of them on one quote. Each site gets its own report and photos, so records stay tidy.
Part by part
School, care home and staff kitchens
Lighter kitchens can often go longer between changes. The interval is set to fit.
Mesh filters
Layers of mesh catch grease droplets. In a busy kitchen, mesh soon blocks, so they need changing often.
