Landlords, agents and facilities managers
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so records stay tidy.
Grease filter exchange in Ash
Washing filters in the kitchen sink is messy and easily missed on a busy week. An exchange service means clean filters arrive and greasy ones leave, so the canopy is never left without filters. The work covers restaurants and pubs, wall canopies and school and hospital kitchens, and the jobs we see most are smoke and heat lingering under the hood and grease building up behind the canopy filters.
In a small place like Ash, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. Access, parking and timings are agreed before the day.
For insurers and inspectors, the record counts. That’s why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Baffle filters
A clogged baffle filter restricts airflow. A clean exchange set brings the airflow back.
Busy restaurant and pub kitchens
In a busy kitchen, filter washing is easy to skip. An exchange service takes it off the rota.
Staff cleaning versus specialist work
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Aftercare tips
After the visit, a few habits help the work last:
- Keep filter exchange and TR19 cleaning on the same plan
- Keep the extract on whenever the range is in use
- Report damaged filters so they can be replaced
- Keep canopy surfaces wiped down
Fresh filters improve airflow at the canopy from the moment they’re fitted. Keep the extract running while you cook so they catch grease as intended.
If cooking has stepped up, the filter schedule should too. Adjusting the schedule now prevents a build-up behind the canopy.
What we do, step by step
Everything the job needs comes with us, including protection sheets, the right tools and access kit. You only need to give us clear access and switch off what needs to be off. The visit takes anything from a few minutes to an hour or so, depending on the number of filters. For a village or hamlet like Ash, tell us about narrow lanes, gates and parking when you book.
- First, we check the canopies and the filters in them.
- We note any filters that are bent, damaged or missing.
- 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.
Preparing for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Make sure someone can let us in and lock up afterwards
- Tell us the best time to work, such as after service or at a weekend

Questions from Ash
Who would carry out a food hygiene inspection at a kitchen in Ash?
Kitchens in Ash are inspected by Sevenoaks council’s environmental health officers. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Do you clean school canteen extracts around Ash out of term?
Yes, out-of-term visits are normal for schools. The FSA’s register shows about 4 schools and colleges with food registrations within roughly a mile and a half of Ash. Just phone us on 0345 646 2711 or drop us a line with your term dates and we will plan around them.
Which accreditations do you hold?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
How long will you be on site?
It depends on the size of the system, but for a typical site it takes a short visit, depending on how many filters the canopies hold. We will give you a better idea when we quote.
Do I get a report after the visit?
Yes, always. The report is dated and includes photos, plus a certificate via the BESCA Vent Hygiene Elite portal for TR19® Grease cleans. File it with your fire safety records.
Are you fully insured?
Yes. Duct Doctor is fully insured, and the details are available on request.
How regularly do grease filters need exchanging?
That depends on the cooking. Kitchens that fry and grill all day need changes more often than kitchens that cook less. We set a schedule that suits your kitchen.
Can we book visits on a schedule?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.
Honest limits
In fairness, there are a few things this work won’t fix:
- Extraction problems caused by the fan rather than the filters
- A canopy too small for the cooking beneath it
- Cooking smells reaching neighbours, which need odour control
If you are not sure, just ring 0345 646 2711 or send us an email and we’ll give you a straight answer.
What the work covers
- Mesh filters
- Island canopies
- Restaurants and pubs
- Wall canopies
- Baffle filters
- School and hospital kitchens
What happens if it’s left?
Grease dripping from the canopy is a sign the filters cannot hold any more. Drips land on surfaces and equipment below, which an EHO may well notice. Systems in rural buildings are often out of sight and out of mind.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re not sure what’s needed, give us a ring on 0345 646 2711, or email photos for straight advice and a fixed quote.

Grease filter exchange in Ash: the local picture
Food Standards Agency data counts about 8 restaurants, cafés and canteens and about 4 takeaways and sandwich shops in and around Ash, up to about a mile and a half out. Each canopy among them has filters that load with grease and need swapping or cleaning. Kitchens in Ash get their food hygiene inspections from Sevenoaks council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Our report lists what was cleaned and when, which is useful to have ready. Kent Fire and Rescue Service covers Ash. 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.
School kitchens, at schools like New Ash Green Primary School for example, are normally cleaned in the holidays so no lunches are lost. A hospital like Darent Valley Hospital, about 5.6 miles north, is the kind of site where a kitchen may cook for patients, staff and visitors all day. Volunteers running a hall kitchen near Parish Church of Saint Peter and Saint Paul, or anywhere in Ash, may not know when the extract was last cleaned, and a grease test settles it.
