About our grease filter exchange in Belgravia
Whether your canopy has baffle or mesh filters, they load up with grease. Once they’re clogged, airflow drops and the fan has to work harder. Regular exchange keeps the air moving. The work covers baffle filters, restaurants and pubs and school and hospital kitchens, and people most often call us about filter washing that keeps being missed and a greasy plenum behind the filters.
In a London area like Belgravia, 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, so a regular TR19® clean protects everyone in it.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Managing agents and facilities teams in Belgravia
From a single site to a large estate, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Keeping the system healthy
Once we’ve finished, these simple steps help:
- Never leave gaps in the filter bank
- Report a dripping canopy early
- Tell us if the menu or opening hours change
- Always run the extract while cooking
If the plenum behind the filters looks greasy, we say so. That might mean bringing a TR19® clean forward, and we can arrange it.
Clean filters plus regular full cleans keep the system in good health. A maintenance plan that covers both keeps everything on track.
Staff cleaning versus specialist work
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We will take a look and send you a fixed quote.
When something else is needed
Before you book, it helps to know what’s not included:
- A noisy or failed extract fan
- Cooking smells reaching neighbours, which need odour control
- A heavily greased plenum or canopy, which needs cleaning to TR19
If in doubt, phone us on 0345 646 2711 or send us an email and we’ll say what we think before you book.

How the visit works
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off.

- We record the number, size and type of your filters.
- An exchange schedule is agreed to suit your cooking.
- On each visit, we remove the greasy filters.
- A clean set is fitted and checked for gaps.
- The dirty filters leave with us and the next visit is booked.
Preparing for the visit

FAQs for Belgravia
Can you come to Belgravia after we close?
Yes, out-of-hours work is a big part of what we do. That way a site in Belgravia does not have to lose a day’s trading. Just give us a ring on 0345 646 2711, or email photos with your opening times and we will plan around them.
Who would carry out a food hygiene inspection at a kitchen in Belgravia?
That is Westminster council, whose environmental health officers carry out food hygiene inspections in Belgravia. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Do you take the used filters away?
We take them away. That is how an exchange works: you always have a clean set fitted, with no washing for your team.
Can you set up regular visits?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
Are you accredited?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.
How long does the visit take?
We’ll confirm the time with your quote. In most cases, the work takes well under an hour for most canopies.
What do you do with what you remove?
We contain it and take it with us. We collect grease, debris and waste water as we go, so it does not spread.
What if some of our filters are damaged?
Each filter is looked at when we exchange. Any that are bent or damaged are flagged since a poor fit lets grease past.
Do you need grease filter exchange in Belgravia?
Sometimes a filter is taken out and never put back. A missing filter leaves an open route into the system and on into the ductwork.
What we’re most often called out for:
- Grease building up behind the canopy filters
- A canopy running with filters missing
- Filters that leave gaps in the canopy
- Filters left unwashed on busy weeks
Commuter trade near London Victoria station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands.

Kitchen extracts in Belgravia
According to Food Standards Agency records, there are about 137 bars, pubs and nightclubs and about 172 hotels and B&Bs across Belgravia and its immediate surroundings (about a mile and a half). Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Food hygiene inspections in Belgravia are the job of Westminster council’s environmental health team. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Keeping each certificate and photo report on file helps show the extract is looked after. Overnight is the normal time to clean a London kitchen extract, so trading isn’t affected.
If you run catering at a healthcare site, such as a hospital like London Lock Hospital about within half a mile north-east, the extract may need cleaning more often than a part-time kitchen. Volunteers running a hall kitchen near St Peter's Church, or anywhere in Belgravia, may not know when the extract was last cleaned, and a grease test settles it.
