Grease filter exchange in Mitcham, done properly
The filters in the canopy are the first thing cooking vapour meets. Their job is to stop grease getting further into the system and they do it best when they’re clean. With grease filter exchange, clean filters replace greasy ones at regular intervals. We’re often asked to deal with grease dripping from the canopy and staff short of time to wash filters, across school and hospital kitchens, baffle filters and mesh filters.
In a London area like Mitcham, 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.
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, and we are fully insured.

Why act early in Mitcham
Once filters are saturated, more grease gets past them. The ductwork then loads up faster, and grease may build up faster than the cleaning interval allows. A busy site in Mitcham builds up dirt and wear quickly, so putting it off makes the eventual job larger.
The price reflects the work, not guesswork. That is why every job is surveyed first, and why the quote is fixed before work begins.

How we price grease filter exchange
A fixed price needs a few facts first. We look at:
- How many systems or sites are involved
- How big the system is
- The condition we find in the survey
- Site requirements such as sign-in and permits
We don’t list prices on the website, because each job is priced on what it involves. For a fixed quote, phone us on 0345 646 2711 or send us an email, and we will talk you through it.
Asking for a quote
What to send for a quote:
- Any previous report or certificate
- The postcode and the type of business
- Any access panels or hatches you can see
- A few general shots of the system
For a fixed quote, call us on 0345 646 2711 or drop us a line 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 usually come back within one working day.
Common problems we fix in Mitcham
However long the kitchen cooks each day, the filters see every minute of it. Heavy daily use means fast build-up, so it needs more frequent changes.
Look out for any of the following:
- Filters so greasy the air can barely pass
- A canopy running with filters missing
- Grease left in baffles after washing
- Grease collecting in the filter channels
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Mitcham is Wilson Hospital, about 0.5 miles south-west.
Before booking anyone
- Whether the work can be done while the site is closed
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether the quote is based on a survey or photos
- If the quote is a fixed price or an estimate
Your questions about grease filter exchange in Mitcham
Do you clean school canteen extracts around Mitcham out of term?
Yes, holiday work suits schools best. Around Mitcham, the Food Standards Agency lists about 30 schools and colleges with registered kitchens within a mile and a half or so. You can call us on 0345 646 2711, or send details by email with the dates the site is empty.
Does London parking affect a job in Mitcham?
A loading bay, a visitor permit or off-street space near the site in Mitcham makes the visit easier to plan. Much of our London work is done overnight, which helps.
What does TR19 mean?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Do you have insurance?
Yes. Full insurance covers our work, and we’ve been trading since 2009.
Which grease filters does the service cover?
The common types of grease filter: baffle and mesh. Tell us what you have when you give us a ring on 0345 646 2711, or send details by email and we will confirm it on site.
Do you take the used filters away?
We do. The dirty filters are taken away for cleaning and the clean set stays in the canopy.
Do you deal with bent or broken filters?
Each filter is looked at when we exchange. We tell you about any that are damaged, because gaps let grease into the plenum.
Can you give a price for filter changes?
We price it on the number of filters and the visit frequency. Send us details or pictures and we’ll quote quickly.
Part by part
The plenum
Behind the filters sits the plenum, where air gathers before the duct. Grease that gets past the filters settles there.
Busy restaurant and pub kitchens
Heavy cooking means more grease reaching every part of the system. Changing them on time protects the ducts behind.
What grease filter exchange looks like in Mitcham
Food Standards Agency records list about 143 cafés, restaurants and staff canteens and about 60 takeaways in Mitcham and the streets around it, up to about 1.5 miles out. Swapping filters on a schedule keeps kitchens like these drawing air properly. London Fire Brigade covers Mitcham. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. Most London extract cleaning happens at night, after the last service.
Church and community hall kitchens, near St. Mark's Church or anywhere around Mitcham, are easy to forget, but their extracts collect grease like any other. For schools such as St Thomas of Canterbury Catholic Primary School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed.

How the visit works
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool first, and the area around the work is covered and protected. The work itself takes a few minutes per canopy, longer for a large kitchen with several canopies. Loading bays, visitor permits and roof access are the first things we ask about for a site in Mitcham.
- The filters in each canopy are measured and counted.
- We set the interval with you.
- On each visit, we remove the greasy filters.
- Clean filters go in and we check they sit snugly.
- We take the greasy set away and confirm the next date.
Before we arrive
- Have your last certificate or report to hand
- Clear loose items from the work area
- Make sure someone can let us in and lock up afterwards
