Grease filter exchange in Wrotham
Cleaning filters by hand takes staff time and is easy to put off. With a filter exchange, we bring a clean set and take the dirty one away and the canopy is refilled straight away. The work covers baffle filters, restaurants and pubs and island canopies, and the jobs we see most are filters left unwashed on busy weeks and poor airflow through the filters.
In a small place like Wrotham, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. We agree access and timings in advance.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

Common problems we fix in Wrotham
Kitchens in Wrotham, as everywhere, find filter washing slips down the list on busy weeks. It only takes a couple of missed weeks for filters to fill with grease.
What we’re most often called out for:
- A canopy running with filters missing
- Weak extraction at the canopy
- Grease filters clogged with grease
- Staff short of time to wash filters
Healthcare kitchens, like those at hospitals such as Sevenoaks Hospital (about 5.1 miles west), often cook for long hours, which puts them in BESA’s heavier-use bands.

What else we do in Wrotham
What affects the cost of grease filter exchange
The quote reflects the site in front of us. We consider:
- Any permits to work or inductions
- Whether we need access equipment or extra panels
- Whether several sites go on one quote
- Parking and loading at the site
You will not find a price list here, because each job is priced on what it involves. For a fixed quote, call 0345 646 2711, or email photos, and we will talk you through it.
Asking for a quote
When you call or email, it’s useful to have:
- A few general shots of the system
- Close-ups of filters, grilles, hatches or access panels
- The times we could work without disrupting the site
- Where the plant sits or the system leaves the building, such as a roof or outside wall
If you need grease filter exchange in Wrotham, give us a ring on 0345 646 2711 or use the quote form. Let us know the site type and the opening hours, plus pictures or the previous report if they’re to hand. A fixed quote typically follows within one working day.
Keeping the system healthy
So the system stays in good health:
- Never leave gaps in the filter bank
- Clear anything stored on or near the canopy
- Tell us if the menu or opening hours change
- Watch for grease drips between visits
If the plenum behind the filters looks greasy, we say so. That might mean bringing a TR19® clean forward and we can book that in.
A kitchen that’s getting busier needs its filters changed more often. Adjusting the schedule now prevents a build-up in the ducts.
Different parts, different methods
Mesh filters
Older or smaller canopies often use mesh filters. We exchange them on the same basis as baffles.
Busy restaurant and pub kitchens
High-output kitchens clog filters quickly. They often need the shortest exchange interval.
Wrotham kitchens: local notes
There are about 7 restaurants, cafés and works canteens and about 7 takeaways within roughly a mile and a half of the centre of Wrotham, according to the Food Standards Agency’s register. Swapping filters on a schedule keeps kitchens like these drawing air properly. Wrotham sits within the area of Kent Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. It’s Tonbridge and Malling council that sends environmental health officers to food businesses in Wrotham. 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.
Volunteers running a hall kitchen near Church of St George, or anywhere in Wrotham, may not know when the extract was last cleaned, and a grease test settles it. Term dates shape school work: for a school like Wrotham School, an extract clean fits neatly into a half-term or summer break.

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’ll take a look and send you a fixed quote.
Wrotham: your questions answered
Can the work in Wrotham be done at night or at weekends?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Wrotham needn’t be disturbed. Just call 0345 646 2711, or send details by email with your opening times and we will plan around them.
Which fire and rescue service is responsible for Wrotham?
Kent Fire and Rescue Service is the fire and rescue service for Wrotham. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Will we have to shut during the visit?
Not typically. Visits are timed for when the area is closed, such as overnight or at a weekend, so you keep your normal hours.
How long will you be on site?
On site, it takes less than an hour in most kitchens. Bigger or more complicated systems take longer, and the quote will say how long.
What happens to the dirty filters?
Yes. Used filters go with us to be cleaned and the clean set stays in the canopy.
Is there a cleaning option for the filters we have?
Yes, filter cleaning is available. The first step is looking at the filters you have, as damaged ones may be better replaced.
Where does the waste go?
It leaves the site with us at the end of the visit. While we work, it’s kept contained to keep the area clean.
Does the report say when we need you again?
Yes. The interval depends on how much the system is used and what we find, and we explain the reasoning on the report.
For landlords and multi-site operators
For anyone managing more than one site, we can schedule visits across all of them on one quote. Each site gets its own report and pictures, so records stay tidy.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side and send the paperwork to whoever needs it.
