Staff cleaning versus specialist work
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
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. Leave those to us.
Grease filter exchange for kitchens and businesses in Kingsash
A filter service works alongside TR19® cleaning, not instead of it. Clean filters reduce the grease reaching the ducts though vapour still carries some grease past them. So the canopy, plenum and ducts still need their full TR19 clean. The work covers wall canopies, restaurants and pubs and island canopies, and common reasons people get in touch are grease dripping from the canopy and a greasy plenum behind the filters.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.
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’re fully insured.

Why deal with it now?
Filters full of grease are fuel sitting right above the cooking. A flare-up on the range can reach them, and from there into the duct. Keeping filters clean takes some of that fuel away. Out of sight is the usual reason a rural system goes too long without attention.
You won’t find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we will explain what it covers.

When to call us in Kingsash
Long cooking hours in Kingsash or anywhere else mean more grease on the filters. Heavy daily use means fast build-up so changes need to come round sooner.
What we are most often called out for:
- Blocked baffle filters
- Poor airflow through the filters
- Gaps where filters have been removed
- A greasy plenum behind the filters
Church and community hall kitchens, near Old Church of St John the Baptist or anywhere around Kingsash, are easy to forget, but their extracts collect grease like any other.
Questions to ask before booking

How the visit works
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. The visit takes a short visit, depending on how many filters the canopies hold. A few pictures of the system help us make the most of a visit to a place like Kingsash.
- 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.
How to prepare
- Mention any sign-in, permit or induction we need
- Allow time for equipment near the work to be turned off and cool down
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

Honest limits
To be straight with you, some problems need a different fix:
- Grease already built up in the ductwork, which needs a full TR19 clean
- A heavily greased plenum or canopy, which needs cleaning to TR19
- Cooking smells reaching neighbours, which need odour control
If in doubt, give us a ring on 0345 646 2711, or send details by email and we’ll say what we think.
Parts of the system we cover

For landlords and multi-site operators
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Records are where multi-site compliance often slips. Each visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.
Grease filter exchange around Kingsash
The FSA’s food hygiene register includes about 4 pubs and bars in and around Kingsash, up to about a mile and a half out. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Fire safety in Kingsash falls to Buckinghamshire 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. Food hygiene inspections in Kingsash are the job of Buckinghamshire council’s environmental health team. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Our report lists what was cleaned and when, which is useful to have ready.
For schools such as Wendover House School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed. If you run catering at a historic house or estate in the area (Cholesbury Manor House is about 2.7 miles east), event kitchens in older buildings often have awkward duct runs that need planning.

Part by part
The plenum
A greasy plenum is a sign filters have been left too long or that the next TR19 clean is due.
Baffle filters
A clogged baffle filter restricts airflow. A clean exchange set brings the airflow back.
