- Hand-washed filters that still look greasy
- Filters left unwashed on busy weeks
- Smoke and heat lingering under the hood
Looking after it afterwards
Good habits slow the build-up between visits. A few tips:
- Keep the extract on whenever the range is in use
- Report damaged filters so they can be replaced
- Clean the canopy surfaces regularly
- Keep the canopy clear for exchange visits
Fresh filters improve airflow at the canopy from the moment they’re fitted. Keep the extract running while you cook so the filters do their job.
Bent or missing filters let grease straight past. Replacing them early protects the plenum and ductwork.
How we handle grease filter exchange in Wandsworth
Each visit is quick and tidy. We lift out the dirty filters and fit a clean set and make sure there are no gaps between them. If something looks wrong, we tell you. If you have grease collecting in the filter channels and filters left unwashed on busy weeks, we can help.
Across London, many commercial kitchens are squeezed into basements and narrow back-of-house spaces, with extract ducts that can climb several floors to discharge at roof level. In Wandsworth, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
Think of the report as the system’s health record: a dated account with photos of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

Why act early in Wandsworth
Grease-loaded filters are a fire risk in their own right. 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. London buildings are shared, so a fire or failure in one system can reach the neighbours above and beside you.
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. You will have a fixed price before work begins.

How we price grease filter exchange
Every site gets its own quote. This is what makes a difference:
- Site requirements such as sign-in and permits
- Parking and loading at the site
- The size of the system
- One-off work versus a regular cycle
The price reflects the work, not guesswork. That is why every job is surveyed first, and why the quote is fixed before we start.
What to send for a quote
Many jobs can be priced from pictures and some basics. Send what you can of the following:
- The roof, plant room or outside wall the system runs to
- The times we could work without disrupting the site
- The site address and the type of premises
- Any previous report or certificate
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Common questions in Wandsworth
Can you come to Wandsworth after we close?
Yes, nights and weekends are routine for us. The work in Wandsworth can fit around your hours. Let us know the hours you are closed and we will book within them.
Which fire service covers Wandsworth?
Wandsworth is in the area of London Fire Brigade. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Is there a survey before the work?
Yes, every time. We diagnose before we treat: the survey tells us what the system needs and how to reach it, and the quote is based on that.
Can damaged filters stay in the canopy?
A bent filter leaves a gap for grease. We flag any we find so they can be replaced.
Is TR19 a legal requirement?
No. The law sets the duty, and TR19® is the recognised benchmark for meeting it. Under the Fire Safety Order 2005, the responsible person must reduce fire risk, and many insurers can refuse or reduce a claim without proof of cleaning.
Do you handle baffle and mesh filters?
Baffle filters and mesh filters. Tell us what you have when you call us on 0345 646 2711, or send details by email and we’ll confirm it on site.
Can we skip TR19 cleans if the filters are changed regularly?
It isn’t. The rest of the system still collects grease at the right interval.
Do you work with multi-site operators?
Yes. One number covers all your sites in our area, and visits can be set on a regular cycle.
What grease filter exchange looks like in Wandsworth
Food Standards Agency data counts about 499 restaurants, cafés and works canteens and about 89 takeaways within roughly a mile and a half of the centre of Wandsworth. Swapping filters on a schedule keeps kitchens like these drawing air properly. Overnight is the normal time to clean a London kitchen extract, so trading is not affected. The fire and rescue service for Wandsworth is 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 St Anne's CofE Primary School for example, are usually cleaned in the holidays so no lunches are lost. If you run catering at a healthcare site, such as a hospital like Royal Hospital for Neuro-disability about 1 mile west, the extract may need cleaning more often than a part-time kitchen.

How the job changes from site to site
Baffle filters
When baffles fill with grease, less air gets through. A clean exchange set brings the airflow back.
Mesh filters
Mesh filters use layers of metal mesh to trap grease. In a busy kitchen, mesh soon blocks, so they need changing often.
The process
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes a short visit, depending on how many filters the canopies hold. In a London area like Wandsworth, parking, loading and building access are planned before the day of the work.
- We start by noting how many filters you have and what type they are.
- Together we set how often the filters should be changed.
- On each visit, the dirty filters come out of the canopy.
- Clean filters go straight back in, seated properly with no gaps.
- We flag any damaged filters or anything wrong with the canopy.
Preparing for the visit
- Arrange a key holder or contact on site
- Clear the space around the work
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

When to call us in Wandsworth
The type of cooking matters. Frying, grilling and chargrilling produce far more grease than steaming or baking so no single schedule suits every kitchen.
What we’re most often called out for:
- Filter washing that keeps being missed
- Drips falling from the filters onto equipment
- Grease collecting in the filter channels
- Gaps where filters have been removed
A hall kitchen that only cooks for events, whether near St Anne's Church or elsewhere in Wandsworth, still needs its extract cleaned, just less often.
