About our grease filter exchange in Ratcliff
A filter that doesn’t sit right lets grease straight past. Bent, damaged or missing filters leave gaps, so we check every one at each visit. Damaged filters are flagged so they can be replaced. Common call-outs are for smoke and heat lingering under the hood and filters left unwashed on busy weeks, across baffle filters, mesh filters and island canopies.
In London, few kitchens can spare a day to close, so extract cleaning in Ratcliff is usually done overnight, after the last service. Before the clean, we agree loading, parking and roof access with whoever manages the building.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Fixed quotes for grease filter exchange in Ratcliff
The diagnosis comes before the price. The main factors are:
- The times the site is available
- Whether it’s a one-off visit or part of a schedule
- Whether we need access equipment or extra panels
- Site requirements such as sign-in and permits
Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote and give you a fixed price before work begins.
Asking for a quote
When you contact us, these details help:
- Problems your staff have spotted

Why it’s worth doing now in Ratcliff
In Ratcliff, as everywhere, a filter service is not a substitute for TR19 cleaning. They do help keep the system in better shape between cleans and the canopy and plenum stay cleaner. In Ratcliff, as across London, ductwork often passes through shared risers and other people’s space.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re unsure, ring 0345 646 2711 or send us an email and we’ll give you an honest view and a fixed quote.

Looking after it afterwards
Good habits slow the build-up between visits. A few tips:
- Look out for drips from the canopy
- Keep the canopy clear for exchange visits
- Keep every filter in place during service
- Keep canopy surfaces wiped down
Fresh filters improve airflow at the canopy from the moment they’re fitted. Always run the extract during cooking so the filters do their job.
Saturated filters let more grease through. Getting onto a regular exchange now keeps grease out of the plenum and ductwork until the next TR19 clean.
Staff cleaning versus specialist work
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We can diagnose it and quote.
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.
What we do, step by step
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. The visit 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 Ratcliff.
- We count and measure the filters in every canopy.
- Together we set how often the filters should be changed.
- At each visit, the greasy filters are lifted out.
- Clean, dry filters are fitted in their place, with no gaps left between them.
- Anything we notice, such as bent filters or a dirty plenum, is pointed out.
Before we arrive
- Dig out any earlier paperwork for the system
- Let us know about parking and loading
- Tell us about site rules, permits or sign-in
Getting a quote
Every quote begins with a look at the system, either from photos and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before we start.
Advice
Managing agents and facilities teams in Ratcliff
Whether it’s one building or many, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with pictures.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side and send the paperwork to whoever needs it.
Different parts, different methods
The plenum
Heavy grease in the plenum often follows clogged or missing filters or that the next TR19 clean is due.
Canopy filter housings
Every exchange includes a check of how the filters sit, because gaps let grease through.
Kitchen extracts in Ratcliff
The FSA’s food hygiene register shows about 1,461 restaurants, cafés and works canteens and about 459 takeaways and sandwich shops in Ratcliff and the streets around it, up to about 1.5 miles out. Each canopy among them has filters that load with grease and need swapping or cleaning. Ratcliff is covered by London Fire Brigade. 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. Kitchens in Ratcliff get their food hygiene inspections from Tower Hamlets council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Before-and-after photos from each clean are a simple way to show the extract is in hand.
A hospital like The Royal London Hospital, about 0.8 miles north-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day. If you run a café or takeaway near Limehouse station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits. If you run a church or community hall kitchen, near Royal Foundation of St Katharine or elsewhere in Ratcliff, its extract still collects grease from every lunch and event.

Questions from Ratcliff
Which council inspects kitchens in Ratcliff?
Kitchens in Ratcliff are inspected by Tower Hamlets council’s environmental health officers. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
What do you need to know about parking in Ratcliff?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Where restrictions apply in the day, an evening or overnight visit usually gets round them.
Can damaged filters stay in the canopy?
A bent filter leaves a gap for grease. We point them out on the visit and explain what’s needed.
What happens if you can’t reach some of it?
They’re listed in the report, never skipped quietly. You’ll know exactly which parts weren’t reached and why, and we can quote to improve the access.
What should go in our maintenance log?
Everything that shows the system is looked after: reports, certificates, photos and your own cleaning or check logs. A single log for each site works best.
Do we need to close the kitchen while filters are changed?
A change takes well under an hour for most canopies, so disruption is small. We plan visits outside your busiest times wherever we can.
Are you fully insured?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
Do you work in Ratcliff?
Yes. Our area takes in London and the counties of South East England, and that includes Ratcliff.
