Common questions in Devil's Den
Can you come to Devil's Den after we close?
Yes. We work evenings, overnight and at weekends. That way a site in Devil's Den does not have to lose a day’s trading. When you call 0345 646 2711 or send us an email, mention when the site is quiet.
Which environmental health team covers Devil's Den?
The local authority for Devil's Den is Maidstone council, and its environmental health team does the inspecting. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Do you handle baffle and mesh filters?
Baffle and mesh filters are both covered. We check what’s in your canopies first and set up the service around them.
Do we lose a day’s trading?
Not normally. We work when the area is out of use, such as evenings, overnight, early mornings or weekends, so the site can carry on as normal.
Which kinds of sites do you work on?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
What paperwork should we keep on file?
Everything that shows the system is looked after: reports, certificates, pictures and your own cleaning or check logs. A single log for each site works best.
Do you offer emergency callouts?
Yes. There’s a 24/7 emergency line for anything that cannot wait until a planned visit. Ring any time and tell us what’s happened.
Do you work with multi-site operators?
Yes. You deal with one contact for every site in our area, and visits can be set on a regular cycle.
Grease filter exchange for kitchens and businesses in Devil's Den
Each visit is quick and tidy. The greasy filters come out, clean ones go in, and we check they’re seated with no gaps. Anything that needs attention is pointed out. If you have weak extraction at the canopy and filter washing that keeps being missed, we can help, from wall canopies, school and hospital kitchens and baffle filters onwards.
In a small place like Devil's Den, 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. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

What we are called out for in Devil's Den
Kitchens in Devil's Den, as everywhere, find filter washing slips down the list on busy weeks. A missed wash or two is all it takes for a filter bank to clog.
Look out for any of the following:
- Poor airflow through the filters
- Grease building up behind the canopy filters
- Filters so greasy the air can barely pass
- Staff short of time to wash filters
Whether the kitchen is in Devil's Den itself or nearby, a TR19® clean covers the whole system, canopy to discharge.

- What hours they’ll be on site
- If they look at the system before pricing

Devil's Den kitchens: local notes
According to Food Standards Agency records, there are about 3 pubs, bars and clubs in and around Devil's Den, up to about a mile and a half out. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Environmental health officers from Maidstone council inspect food businesses in Devil's Den. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Before-and-after photos from each clean are a simple way to show the extract is in hand. The fire and rescue service for Devil's Den is Kent Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.

Part by part
Busy restaurant and pub kitchens
The more a kitchen cooks, the more grease the filters see. Regular changes help protect the ductwork.
Baffle filters
Baffle filters are a common choice for commercial canopies. They still need regular cleaning, because the grease they collect builds up.
What staff can safely do
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Between visits
No system stays clean for ever, but care slows the build-up. Our tips:
- Keep the canopy clear for exchange visits
- Keep canopy surfaces wiped down
- Watch for grease drips between visits
- Don’t let the full clean slip because filters are changed
If the plenum behind the filters looks greasy, we say so. It can be a sign that a full TR19® clean is due, and we can arrange it.
Damaged filters leave gaps in the defence. Replacing them early protects the plenum and ductwork.
What affects the quote in Devil's Den
There’s no set price list, because no two systems are the same. What we look at:
- The condition of the system
- How big the system is
- How easy every part is to reach
- Working hours and out-of-hours timing
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.
What we need to know
There’s no need for technical detail. It helps if you can send:
- Detail shots of panels, filters and grilles
- Any previous report or certificate
- Any symptoms, from odd noises to smells or leaks
- Where the site is and what kind of site it is
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, before any work starts.
What happens if it’s left?
Once filters are saturated, more grease gets past them. That makes the next full clean a bigger job, and grease may build up faster than the cleaning interval allows. Equipment tucked in a roof space or outbuilding near Devil's Den rarely gets looked at unless someone books it.
We don’t list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll explain what it covers.
