Advice
About our grease filter exchange in Fritwell
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 and the canopy is refilled straight away. Typical jobs include a greasy plenum behind the filters and hand-washed filters that still look greasy, on restaurants and pubs, mesh filters and island canopies.
In a village or hamlet like Fritwell, the kitchens that need extract cleaning are normally a pub, a school, a care home or a hall kitchen, wherever there is one. Each still has a canopy and duct that collect grease, whatever the size of the place.
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 carry full insurance.

How the job changes from site to site
Busy restaurant and pub kitchens
Kitchens that fry and grill all day load their filters fast. Their exchange schedule is typically the tightest.
School, care home and staff kitchens
A longer exchange interval may suit lighter cooking. The interval is set to fit.
Fritwell kitchens: local notes
Fritwell sits within the area of Oxfordshire 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. At about 58 miles from central London, Fritwell sits well inside the area we cover. Visits are booked around your hours, evenings and weekends included.
If you look after a school kitchen, at a school such as Fritwell Church of England Primary School or anywhere near Fritwell, the holidays are the usual time for a TR19® clean. A hall kitchen that only cooks for events, whether near Church of St Olave or elsewhere in Fritwell, still needs its extract cleaned, just less often.

Why act early in Fritwell

When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account and give you a fixed price before any work starts.

Fritwell: your questions answered
Who would carry out a food hygiene inspection at a kitchen in Fritwell?
Kitchens in Fritwell are inspected by Cherwell council’s environmental health officers. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Which fire service covers Fritwell?
Oxfordshire Fire and Rescue Service is the fire and rescue service for Fritwell. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
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.
Will I get paperwork for my records?
Yes. It’s the record insurers and inspectors ask to see: a written, dated record with pictures of what we did and anything we couldn’t access.
Do you clean filters as well as exchanging them?
Yes. Some kitchens prefer their own filters cleaned on a schedule, and others prefer a straight swap. We make sure the canopy is ready for service either way.
Do you work in Fritwell?
Yes. Our area takes in London and the counties of South East England, Fritwell included.
Does a filter exchange disrupt service?
A filter change is quick and can be timed around service. The canopy shouldn’t be used without filters, so we swap them in one go.
Does a filter exchange replace TR19 cleaning?
It does not. Filters don’t catch everything, so grease still reaches the ductwork and the whole system still needs its TR19 clean.
What affects the cost of grease filter exchange
We don’t publish a price list, because no two systems are the same. The quote depends on:
- One-off work versus a regular cycle
- What state the system is in
- Any permits to work or inductions
- How big the system is
The cost depends on the size of the system, the condition it’s in and access to every part of it. You get a fixed price before any work starts, so there are no surprises.
Asking for a quote
There’s no need for technical detail. It helps if you can send:
- Any access panels or hatches you can see
- Wide pictures of the system and the area around it
- The paperwork from the last visit, if you have it
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
What staff can safely do
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
When to call us in Fritwell
Washing filters by hand does not always get them clean. Grease lodges deep in baffles and mesh, and a quick rinse leaves it there.
Look out for any of the following:
- Weak extraction at the canopy
- A canopy that drips grease
- Bent or damaged filters that don’t sit properly
- Grease collecting in the filter channels
Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Fritwell is Bicester Community Hospital, about 5.4 miles south-east.
