Helping us quote
Many jobs can be priced from pictures and some basics. Useful things to send:
- Problems your staff have spotted
- Your last certificate, test record or report
- Detail shots of panels, filters and grilles
- Wide pictures of the system and the area around it
Every quote begins with a look at the system, from your pictures and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work so you know the cost before we start.
Grease filter exchange in Merton
In Merton, our filter exchange runs on a schedule set by how much the kitchen cooks. Busy kitchens need changes more often, lighter ones less. The interval is agreed before the first visit. Common call-outs are for grease left in baffles after washing and grease building up behind the canopy filters, across wall canopies, baffle filters and island canopies.
In London, few kitchens can spare a day to close, so work in Merton is normally booked for the night or the early hours. Parking, loading and access to the roof are agreed with the building before the night of the clean.
It’s worth checking any contractor’s accreditations. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

Leave it or put it right?
Once filters are saturated, more grease gets past them. That makes the next full clean a bigger job and grease readings can rise between cleans. A booked night’s work in Merton costs you no trading time; an unplanned closure does.
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. You will have a fixed price before any work starts.
What you get with us
- We’re fully insured
- Survey first, then a fixed quote
- CHAS, SafeContractor and ISO 9001
- One number for every site across the South East and London

What a clean will not put right
We will not sell you work that doesn’t address the problem, so these are the things it will not cover:
- An extract that was undersized from the start
- A fan that’s failing or too weak for the system
- A canopy that needs a proper clean
If you’re not sure, just phone us on 0345 646 2711, or email photos and we will give you a straight answer before booking.
Parts of the system we cover
- Wall canopies
- Restaurants and pubs

Common questions in Merton
Can you clean school kitchen extracts in Merton during the holidays?
Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 39 schools, colleges and universities with registered kitchens within about a mile and a half of Merton. You can give us a ring on 0345 646 2711, or send details by email with the dates the site is empty.
Which council inspects kitchens in Merton?
The local authority for Merton is Merton council, and its environmental health team does the inspecting. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
Do you offer maintenance contracts?
Yes, of course. Send details of the systems and how they’re used and we’ll propose a schedule with a fixed quote.
What happens to the dirty filters?
We do. The dirty filters are taken away for cleaning and the clean set stays in the canopy.
Can we skip TR19 cleans if the filters are changed regularly?
No. Filter exchange works between full cleans, not instead of them. A TR19® clean deals with the whole system, with a certificate and photo report.
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, and we can fit those.
What happens to the waste?
It leaves the site with us when we go. During the work, it’s contained to keep the area clean.
Do we need to close the kitchen while filters are changed?
Most changes take a short visit, depending on how many filters the canopies hold, so the impact is small. We plan visits outside your busiest times wherever we can.
Different parts, different methods
Canopy filter housings
Every exchange includes a check of how the filters sit, because gaps let grease through.
Baffle filters
Baffle filters use overlapping metal blades that force the air to change direction. Grease is thrown out of the airstream and collects on the baffles.
Grease, kitchens and Merton
Food Standards Agency data counts about 352 restaurants, cafés and works canteens and about 68 sandwich bars and takeaways in Merton and the streets around it, up to about 1.5 miles out. Clogged filters slow the airflow, and busy kitchens like these clog them fast. The fire and rescue service for Merton 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. In London, kitchens are typically cleaned overnight, when the kitchen is closed and loading is easier.
Term dates shape school work: for a school like Merton Abbey Primary School, an extract clean fits neatly into a half-term or summer break. Healthcare kitchens, like those at hospitals such as St George's Hospital (about 1.1 miles north-east), often cook for long hours, which puts them in BESA’s heavier-use bands.
Merton is about 1 mile south-east of Wimbledon, in Greater London.

Do you need grease filter exchange in Merton?
Filters get bent and damaged with handling. Damaged filters do not sit flush and grease passes round them.
Signs it’s time to call us include:
- Grease dripping from the canopy
- Filter washing that keeps being missed
- Filters so greasy the air can barely pass
- Filters that come out of the sink still dirty
For kitchens close to Haydons Road station, where the day often starts early and ends late, the extract can be cleaned overnight.

What we do, step by step
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. All told, the work takes less than an hour in most kitchens. Before any visit in Merton, we agree where the van can stop and how equipment reaches the system.
- 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, 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.
Before we arrive
- Make sure equipment near the work can be switched off and left to cool
- Let us know about parking and loading
- Move anything stored near the system
Ask for a quote

Aftercare tips
Looking after the system between visits is straightforward, and it helps at the next visit:
- Book full TR19 cleans alongside filter changes
- Look out for drips from the canopy
- Never leave gaps in the filter bank
- Let us know if your cooking hours increase
We tell you if we spot anything in the canopy that needs attention. That might mean bringing a TR19® clean forward, and we can arrange it.
Filter exchange and TR19 cleaning work best together. A maintenance plan that covers both means neither slips.
