- Grease filters clogged with grease
Landlords, agents and facilities managers
Facilities teams in offices, schools and healthcare sites book us too across Oxfordshire. Larger estates can be phased building by building around the people who use them.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
Grease filter exchange in West Challow
An exchange visit in West Challow doesn’t take long. The greasy filters come out, clean ones go in, and we check they’re seated with no gaps. If something looks wrong, we tell you. If you’re dealing with missing filters in the filter bank and grease filters clogged with grease, we can put it right, from baffle filters, mesh filters and island canopies onwards.
For a kitchen in or near West Challow, the visit is planned around opening hours and the journey, and the clean itself is the same full TR19® job as in any town: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

What we are called out for in West Challow
Washing filters by hand doesn’t always get them clean. Grease hides in the folds of a baffle or the layers of a mesh, and a quick rinse leaves it there.
Most sites get in touch when they notice something like this:
- Grease left in baffles after washing
- Filters so greasy the air can barely pass
- Bent or damaged filters that don’t sit properly
- Weak extraction at the canopy
A hall kitchen that only cooks for events, whether near Church of St Laurence or elsewhere in West Challow, still needs its extract cleaned, just less often.

Questions from West Challow
Which fire and rescue service is responsible for West Challow?
Oxfordshire Fire and Rescue Service is the fire and rescue service for West Challow. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Do you work overnight in West Challow?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in West Challow needn’t be disturbed. Tell us your opening hours when you ask for a quote.
What’s the right interval for changing filters?
It depends on how much and what the kitchen cooks. Kitchens that fry and grill all day need changes more often than kitchens that cook less. We set a schedule that suits your kitchen.
Do you recommend a next date?
Yes. The report recommends when the next visit should be, based on use and what we found.
Does a filter exchange replace TR19 cleaning?
It isn’t. Clean filters help keep grease down, but the ducts and plenum still need cleaning at an interval set by risk assessment.
Will I get paperwork for my records?
Yes. Every visit ends with a written report and photos, covering the work, any areas we couldn’t access and the recommended next date. Kitchen extract cleans to TR19® Grease also get a certificate through the BESCA Vent Hygiene Elite portal.
Are you accredited?
We hold CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Will we have to shut during the visit?
Not normally. The area we are working in has to be out of use while we’re there, so the visit goes in a quiet slot.
What we do, step by step
The first job on site is protection: floors, worktops and anything near the work are covered. Then we make the system safe and start. It takes a short visit, depending on how many filters the canopies hold, and we clear up before we go. A quick note on how to find the site and where to park makes a visit to West Challow run smoothly.
- The filters in each canopy are measured and counted.
- An exchange schedule is agreed to suit your cooking.
- The dirty set is lifted out.
- Clean filters go in and we check they sit snugly.
- The dirty filters leave with us and the next visit is booked.
Preparing for the visit
- Name a contact who can let us in at the agreed time
- Mention any locked doors, roof access or ceiling voids
- Allow time for equipment near the work to be turned off and cool down

Quoting starts with a diagnosis, from your pictures and details or, where that is not enough, a survey on site. Then we send a fixed price so you know the cost before any work starts.

Aftercare tips
Once we have finished, these simple steps help:
- Clean the canopy surfaces regularly
- Make sure we can reach the canopy on exchange day
- Watch for grease drips between visits
- Keep the extract on whenever the range is in use
The next exchange is already in the diary. If cooking increases, we can change filters more often to keep up.
Dripping filters are a clear sign they’re full. Changing them now reduces the fuel above the cooking and the plenum may need a clean as well.
Grease filter exchange in West Challow: the local picture
At about 60 miles from central London, West Challow sits well inside the area we cover. The visit is fixed around your opening hours, not ours. West Challow is covered by Oxfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.

- Greasy ducts and risers that a filter change won’t reach
- A noisy or failed extract fan
- A heavily greased plenum or canopy, which needs cleaning to TR19

What we work on in West Challow
- Wall canopies
- Island canopies
- Mesh filters
- School and hospital kitchens
- Baffle filters
- Restaurants and pubs
What staff can safely do
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
What the work involves, part by part
The plenum
With good filters, less grease ends up in the plenum, but it still needs cleaning as part of TR19.
Mesh filters
Older or smaller canopies often use mesh filters. We exchange them on the same basis as baffles.
