Grease filter exchange for kitchens and businesses in Lewisham
Grease filters are the first line of defence in a kitchen extract. They catch grease before it reaches the plenum and ductwork, but only while they’re reasonably clean. With grease filter exchange, clean filters replace greasy ones at regular intervals. Typical jobs include grease left in baffles after washing and filter washing that keeps being missed, on school and hospital kitchens, mesh filters and restaurants and pubs.
London kitchens are often tucked into basements or the back of a building, and the duct may run up through several floors before it discharges at the roof. For a kitchen in Lewisham, that normally means a longer system to clean and more access panels to plan around.
Every visit ends with a written report and photos, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What we are called out for in Lewisham
Long cooking hours in Lewisham or anywhere else mean more grease on the filters. A kitchen that cooks all day loads its filters quickly so changes need to come round sooner.
Look out for any of the following:
- Smoke and heat lingering under the hood
- Bent or damaged filters that don’t sit properly
- Filters left unwashed on busy weeks
- Blocked baffle filters
For schools such as St Saviour's Catholic Primary School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.

Looking after it afterwards
Results last longer with the right care. Here’s what we suggest:
- Let us know if your cooking hours increase
- Never cook with the extract switched off
- Report damaged filters so they can be replaced
- Keep every filter in place during service
If the plenum behind the filters looks greasy, we say so. That might mean bringing a TR19® clean forward and we can book that in.
A kitchen that is getting busier needs its filters changed more often. Changing the interval early stops grease building up unseen behind the canopy.
What staff can safely do
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
How we price grease filter exchange
We don’t publish a price list, because no two systems are the same. What we look at:
- When the work can happen, such as evenings, overnight or weekends
- How easy every part is to reach
- Where the site is and how we reach it
- How big the system is
We do not list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we will talk you through it.
What we need to know
To help us quote quickly, send us:
- When the site is open and when it’s quiet
- The roof, plant room or outside wall the system runs to
- Where the site is and what kind of site it is
- The paperwork from the last visit, if you have it
Quotes are quick. Call or email with a few details and you’ll usually have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
Common questions in Lewisham
Do you do school kitchen extract cleaning in Lewisham in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 48 schools and colleges with food registrations within roughly a mile and a half of Lewisham. Send us your term dates when you ring 0345 646 2711 or drop us a line, and we’ll fit the work in.
Do you work at weekends in Lewisham?
Yes, evening, overnight and weekend work is normal for us. That way a site in Lewisham does not have to lose a day’s trading. Let us know the hours you’re closed and we will book within them.
What types of premises do you cover?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Is Lewisham in your area?
Yes. Lewisham is part of the area we cover, as part of our area across London and the South East.
Do you take the used filters away?
We take them away. That’s the point of an exchange: you always have a clean set fitted and nothing greasy left on site.
What should go in our maintenance log?
Anything that proves the system is maintained: our reports and pictures, any certificates and your in-house logs. A single log for each site works best.
Do you offer emergency callouts?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we’ll advise on what to do next.
Do you clean filters as well as exchanging them?
Yes, filters can be cleaned on a schedule as well as exchanged. We will talk you through which suits your kitchen when we quote.
What happens on the day
On the day, we arrive 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 before we start, and the area around the work is covered and protected. On site, it takes a few minutes per canopy, longer for a large kitchen with several canopies. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Lewisham.
- We look at the canopies and the condition of the filters.
- We note any filters that are bent, damaged or missing.
- Greasy filters are swapped for clean ones.
- The filters are checked for fit before we go.
- We tell you if the plenum or canopy needs a clean.
Preparing for the visit
- Move anything stored near the system
- Arrange a key holder or contact on site
- Find the previous report, if there is one
