In-house cleaning or a specialist?
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That’s our job.
About our grease filter exchange in Sudbury
A filter service works alongside TR19® cleaning, not instead of it. Clean filters reduce the grease reaching the ducts, but some grease still passes through as vapour. That is why the whole system still needs cleaning to TR19 at the right interval. The work covers baffle filters, school and hospital kitchens and mesh filters, and people most often call us about gaps where filters have been removed and staff short of time to wash filters.
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. In Sudbury, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
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.

The process
We start by comparing what we find with the survey or your pictures. Anything unexpected is raised with you before we go further. After that, the work takes a short visit, depending on how many filters the canopies hold. Getting kit into a London building takes planning, so let us know where we can load and park in Sudbury.
- We record the number, size and type of your filters.
- We set the interval with you.
- The dirty set is lifted out.
- A clean set is fitted and checked for gaps.
- The dirty filters leave with us and the next visit is booked.
How to prepare
- Tell us where we can park and unload
- Move anything stored near the system
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

Advice
Grease filter exchange around Sudbury
Look up Sudbury on the FSA’s food hygiene register and you will find about 157 restaurants, cafés and canteens and about 130 takeaways in Sudbury and the streets around it, up to about 1.5 miles out. Clogged filters slow the airflow, and busy kitchens like these clog them fast. Environmental health officers from Brent council inspect food businesses in Sudbury. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Keeping each certificate and photo report on file helps show the extract is looked after. Night work suits London kitchens, and roads and loading bays tend to be quieter too.
If you look after a school kitchen, at a school such as Sudbury Primary School or anywhere near Sudbury, the holidays are the usual time for a TR19® clean. A hall kitchen that only cooks for events, whether near Church of St Andrew or elsewhere in Sudbury, still needs its extract cleaned, just less often.

Your questions about grease filter exchange in Sudbury
Does London parking affect a job in Sudbury?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Working overnight, as we often do in London, normally makes it simpler.
Which fire service covers Sudbury?
That is London Fire Brigade. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Which records should we keep?
The reports and certificates from each visit, plus your own logs. Insurers, fire officers and EHOs may all ask to see them, so keep them where they can be found quickly.
What accreditations do you have?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.
Do you handle baffle and mesh filters?
We work with both baffle and mesh filters. The first step is recording what you have and plan the exchange around them.
Does a filter exchange disrupt service?
Not for long, and we can time it to avoid service. Cooking shouldn’t happen with the filters out, so we swap them in one go.
How do you protect the area?
By covering it before any work starts. The work is kept contained and leave the area clean.
Will I get paperwork for my records?
Yes, always. The report is dated and includes pictures, plus a certificate via the BESCA Vent Hygiene Elite portal for TR19® Grease cleans. Keep it in your maintenance log.
Do you need grease filter exchange in Sudbury?
However long the kitchen cooks each day, the filters see every minute of it. A kitchen that cooks all day loads its filters quickly, so it needs more frequent changes.
Keep an eye out for these warning signs:
- Filters that come out of the sink still dirty
- Grease building up behind the canopy filters
- Damaged filters letting grease past
- Filters so greasy the air can barely pass
If you run a café or takeaway near Sudbury & Harrow Road station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits.

Aftercare tips
No system stays clean for ever, but care slows the build-up. Our tips:
- Look out for drips from the canopy
- Tell us if a filter is bent or damaged
- Mention it if the kitchen gets busier
- Make sure we can reach the canopy on exchange day
If the plenum behind the filters looks greasy, we say so. That might mean bringing a TR19® clean forward, and we can arrange it.
A kitchen that is getting busier needs its filters changed more often. Changing the interval early stops grease building up unseen in the ducts.
Fixed quotes for grease filter exchange in Sudbury
Sites vary more than people expect. The main factors:
- Where the site is and how we reach it
- When the work can happen, such as evenings, overnight or weekends
- The number of sites or systems
- The condition we find in the survey
Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you are not sure what’s needed, phone us on 0345 646 2711, or email photos for straight advice and a fixed quote.
What we need to know
You do not need the technical terms. Just send:
- The roof, plant room or outside wall the system runs to
- Close-ups of filters, grilles, hatches or access panels
- The times we could work without disrupting the site
- Your last certificate, test record or report
We don’t publish a price list, because no two systems are the same. We look at your system first, from photos or on a visit, then send a fixed quote. To start, call 0345 646 2711 or email us.

Why it’s worth doing now in Sudbury
Grease dripping from the canopy is a sign the filters can’t hold any more. Left, it ends up on equipment, food areas and staff, which an EHO may well notice. A building in Sudbury may have flats or offices above and alongside, and a fault in the system can affect them too.
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at and we will price it together.
