Kitchen extracts in Belvedere
Look up Belvedere on the FSA’s food hygiene register and you’ll find about 54 restaurants, cafés and canteens and about 64 sandwich bars and takeaways within about 1.5 miles of central Belvedere. Each canopy among them has filters that load with grease and need swapping or cleaning. It’s Bexley council that sends environmental health officers to food businesses in Belvedere. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A TR19® certificate and photo report after each clean gives you a record to show an inspector. London jobs normally start after the last service, with loading and roof access agreed with the building first.
A hall kitchen that only cooks for events, whether near Parish Church of All Saints or elsewhere in Belvedere, still needs its extract cleaned, just less often. If you run catering at a healthcare site, such as a hospital like Erith and District Hospital about 0.8 miles south-east, the extract may need cleaning more often than a part-time kitchen. For kitchens close to Belvedere station, where the day often starts early and ends late, the extract can be cleaned overnight.
Belvedere is about 3 miles east of Plumstead, in Greater London.

About our grease filter exchange in Belvedere
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. The work covers school and hospital kitchens, baffle filters and mesh filters, and the jobs we see most are staff short of time to wash filters and blocked baffle filters.
In London, few kitchens can spare a day to close, so work in Belvedere 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.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

How we price grease filter exchange
There’s no set price list, because sites vary so much. The quote depends on:
- The size of the system
- Site rules, permits and inductions
- Whether it’s a one-off visit or part of a schedule
- Whether several sites go on one quote
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. You’ll have a fixed price before work begins.
Helping us quote
To speed up the quote, please include:
- How we’d reach plant on a roof or in a plant room
- The times we could work without disrupting the site
- A few general shots of the system
- Where the site is and what kind of site it is
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
How the job changes from site to site
The plenum
A greasy plenum is a sign filters have been left too long, or that a full clean is due.
Baffle filters
Baffle filters are a common choice for commercial canopies. They don’t clean themselves as the collected grease builds up between the blades.

What else we do in Belvedere
In-house cleaning or a specialist?
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 is where we come in.
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
Aftercare tips
Good habits slow the build-up between visits. A few tips:
- Watch for grease drips between visits
- Clear anything stored on or near the canopy
- Always run the extract while cooking
- Mention it if the kitchen gets busier
Your team carries on as normal, without the filter washing. Just keep the canopy clear for the next visit and tell us if service times change.
Clean filters plus regular full cleans keep the system in good health. A maintenance plan that covers both keeps everything on track.
Why act early in Belvedere
Changing filters on schedule costs far less disruption than a blocked extract. Few maintenance jobs are as easy, and one of the easiest to let slip. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote, and the price is fixed before any work starts.
Why choose Duct Doctor in Belvedere
- Work around your opening hours, with 24/7 emergency cover
- A written report with pictures after each visit
- Fixed quotes, typically within one working day
- Every job surveyed first
What grease filter exchange can’t fix
Grease filter exchange can’t fix everything, and we will tell you before any work starts. It will not put right:
- Greasy ducts and risers that a filter change won’t reach
- A noisy or failed extract fan
- A canopy too small for the cooking beneath it

Questions from Belvedere
Do you work at weekends in Belvedere?
Yes. We work evenings, overnight and at weekends. It means the site in Belvedere keeps running as normal. When you call 0345 646 2711 or drop us a line, mention when the site is quiet.
Which council inspects kitchens in Belvedere?
Kitchens in Belvedere are inspected by Bexley council’s environmental health officers. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
What paperwork should we keep on file?
Every certificate and report from each visit, kept together in your maintenance log with your in-house cleaning records. BESA says certificates should show the date, location and technician.
What does grease filter exchange cost?
The cost depends on your filters and the schedule. Just give us a ring on 0345 646 2711 or send us an email for a fixed quote once we know your canopies.
Do you provide a certificate or report?
Yes, on every job. The report is dated and includes pictures, plus a certificate via the BESCA Vent Hygiene Elite portal for TR19® Grease cleans. File it with your fire safety records.
What does TR19 mean?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t law, but it’s the benchmark.
Can you clean our existing filters instead?
Yes, filters can be cleaned on a schedule as well as exchanged. We’ll talk you through which suits your kitchen when you get in touch.
Where do the greasy filters go?
They leave with us. That is the point of an exchange: clean filters in, dirty ones out and nothing greasy left on site.
What happens on the day
The first job on site is protection: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. The work on site takes less than an hour in most kitchens, and we clear up before we go. Managed blocks in London often need contractors booked in ahead, and we are happy to deal with the agent directly for a site in Belvedere.
- First, we check the canopies and the filters in them.
- Any damaged or missing filters are noted.
- Greasy filters are swapped for clean ones.
- We check the filters are seated and the canopy is ready to use.
- We tell you if the plenum or canopy needs a clean.
Getting ready for the visit
- Mention any parking or loading restrictions
- Mention any sign-in, permit or induction we need
- Have your last certificate or report to hand
