Grease filter exchange in Aldgate
The filters in the canopy are the first thing cooking vapour meets. They catch grease before it reaches the plenum and ductwork and they do it best when they’re clean. Our grease filter exchange service swaps dirty filters for clean ones on a schedule. We’re often asked to deal with blocked baffle filters and hand-washed filters that still look greasy, across wall canopies, baffle filters and island canopies.
London kitchens tend to trade late and open early, so work in Aldgate 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.
The report is your system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

Grease filter exchange around Aldgate
Food Standards Agency records include about 486 pubs, bars and clubs and about 86 hotels and B&Bs within roughly a mile and a half of the centre of Aldgate. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. In London, kitchens are typically cleaned overnight, when the kitchen is closed and loading is easier. Fire safety in Aldgate falls to London Fire Brigade. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Aldgate is London Bridge Hospital, about 0.6 miles south-west. For kitchens close to London Fenchurch Street station, where the day often starts early and ends late, the extract can be cleaned overnight.

What else we do in Aldgate
Different parts, different methods
Canopy filter housings
The filter housing holds each filter at an angle in the canopy. A damaged housing leaves gaps.
Mesh filters
Mesh filters are still found in many canopies. We exchange them on the same basis as baffles.
How the visit works
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes a few minutes per canopy, longer for a large kitchen with several canopies. Managed blocks in London often need contractors booked in ahead, and we’re happy to deal with the agent directly for a site in Aldgate.
- First, we check the canopies and the filters in them.
- Any damaged or missing filters are noted.
- We exchange the dirty filters for a clean set.
- We check the filters are seated and the canopy is ready to use.
- We tell you if the plenum or canopy needs a clean.
How to prepare
- Allow time for equipment near the work to be turned off and cool down
- Let us know how we reach the system, including roofs, risers and plant rooms
- Tell us where we can park and unload

There’s no standard price list, because every site is different. We look at your system first, from photos or on a visit, and then send you a fixed quote. To start, call 0345 646 2711, or email photos.
Advice
Aldgate: your questions answered
Which fire service covers Aldgate?
Aldgate is in the area of London Fire Brigade. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Does London parking affect a job in Aldgate?
Tell us where a van can stop near your site in Aldgate, and about any building rules on loading. Where restrictions apply in the day, an evening or overnight visit normally gets round them.
Are you accredited?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.
How long does the visit take?
On site, it takes well under an hour for most canopies. Larger systems naturally take longer, and we’ll tell you what to expect.
Do you take the used filters away?
The greasy set leaves with us for cleaning, so your staff do not have to wash them. A clean set is fitted in their place.
Do you offer emergency callouts?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we will advise on what to do next.
Are you fully insured?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
Will we have to stop cooking for a filter change?
Most changes take well under an hour for most canopies, so the impact is small. We will fit it around your service wherever possible.
What we’re called out for in Aldgate
The type of cooking matters. Frying, grilling and chargrilling produce far more grease than steaming or baking, so the right exchange interval varies.
Clients typically contact us after spotting something like this:
- Damaged filters letting grease past
- Filters that come out of the sink still dirty
- A canopy that drips grease
- Filter washing that keeps being missed
For schools such as The Aldgate School, kitchen extract cleaning is typically booked for the holidays, when the canteen is closed.
Before booking anyone

- Whether VAT is included
- Whether they recommend a next date
- What’s included in the scope, part by part
What a clean will not put right
Not every problem is solved by grease filter exchange, and we’d rather say so up front. It will not put right:
- Grease already built up in the ductwork, which needs a full TR19 clean
- Odours from the discharge that filters won’t stop
- An extract that was undersized from the start
Not sure which it is? You can call us on 0345 646 2711, or send details by email and we will tell you honestly before you book.

Keeping the system healthy
A little care between visits keeps the system in better shape. We recommend:
- Tell us if the menu or opening hours change
- Clean the canopy surfaces regularly
- Tell us if a filter is bent or damaged
- Never cook with the extract switched off
The next exchange is already in the diary. If cooking increases, we can change filters more often to match.
If cooking has stepped up, the filter schedule should too. Adjusting the schedule now prevents a build-up behind the canopy.
What happens if it’s left?
A filter exchange is a few minutes; a choked extract affects a whole service. It’s one of the simplest parts of looking after the system and few are as easy to forget. London buildings are shared, so a fire or failure in one system can reach the neighbours above and beside you.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re unsure, call us on 0345 646 2711, or send details by email and we will give you an honest view and a fixed quote.
