How we handle grease filter exchange in Caversfield
A clean set of filters is a simple, regular dose of prevention. It keeps airflow up and grease down between full cleans, and it saves your staff a greasy job. The full TR19 clean then gives the system its clean bill of health. Typical jobs include poor airflow through the filters and staff short of time to wash filters, across wall canopies, restaurants and pubs and baffle filters.
Somewhere as small as Caversfield, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Each still has a canopy and duct that collect grease.
For insurers and inspectors, the record counts. That is why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

The process
There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. Most of the time goes on the work itself, which takes well under an hour for most canopies. Rural roads and tight entrances are worth telling us about before a visit to Caversfield.
- We record the number, size and type of your filters.
- An exchange schedule is agreed to suit your cooking.
- On each visit, we remove the greasy filters.
- Clean filters go in and we check they sit snugly.
- The dirty filters leave with us and the next visit is booked.
Before we arrive
- Tell us the best time to work, such as after service or at a weekend
- Tell us about site rules, permits or sign-in
- Name a contact who can let us in at the agreed time
How to get a quote
Every quote begins with a look at the system, from your pictures and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work, before any work starts.

Staff cleaning versus specialist work
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We’ll take a look and send you a fixed quote.
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Your questions about grease filter exchange in Caversfield
Which fire authority looks after Caversfield?
That is Oxfordshire Fire and Rescue Service. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Can you work in Caversfield outside opening hours?
Yes, nights and weekends are routine for us. It means the site in Caversfield keeps running as normal. Your opening times are the first thing we ask for.
How do you keep the site clean during the work?
We start with protection: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
Are you fully insured?
Yes. We are fully insured, and we can share the details when you need 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’re fully insured.
Who has the legal duty for fire safety?
In the words of the Fire Safety Order 2005, it’s the responsible person. It’s normally the employer, or whoever controls the building, and where several people have control, each can have duties. If you’re not sure, check your lease and fire risk assessment.
What’s the right interval for changing filters?
The right interval depends on the kitchen. If filters clog early, the interval needs shortening, and we can change it.
Where do the greasy filters go?
We do. The dirty filters are taken away for cleaning and the clean set stays in the canopy.
Grease filter exchange in Caversfield: the local picture
Food Standards Agency records include about 10 bars, pubs and nightclubs and about 4 hotels and B&Bs within about 1.5 miles of central Caversfield. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. In Caversfield, food businesses are inspected by environmental health officers from Cherwell council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Before-and-after pictures from each clean are a simple way to show the extract is in hand. Oxfordshire Fire and Rescue Service covers Caversfield. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
Term dates shape school work: for a school like Southwold County Primary School, an extract clean fits neatly into a half-term or summer break. Volunteers running a hall kitchen near Church of St Lawrence, or anywhere in Caversfield, may not know when the extract was last cleaned, and a grease test settles it.

Why deal with it now?
For any kitchen in Caversfield, filters can’t stand in for a full TR19 clean. They do help keep the system in better shape between cleans, and that shows when the next clean comes round. A fault that closes a site in a village like Caversfield affects everyone who depends on it.
The price reflects the work, not guesswork. That’s why we survey first, from photos or on site, and why the quote is fixed before we start.

How we price grease filter exchange
Every site gets its own quote. This is what makes a difference:
- Working hours and out-of-hours timing
- Any permits to work or inductions
- What state the system is in
- How many systems or sites are involved
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at, and you will get one fixed quote.
Asking for a quote
When you call or email, these details help:
- The paperwork from the last visit, if you have it
- Problems your staff have spotted
- Photos showing the whole system and its surroundings
- How we’d reach plant on a roof or in a plant room
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before any work starts.
What we’re called out for in Caversfield
Cooking vapour carries grease into the canopy. The filters catch much of it, and day by day they load up and airflow falls away.
Most sites get in touch when they notice something like this:
- Grease building up behind the canopy filters
- Drips falling from the filters onto equipment
- Grease filters clogged with grease
- Hand-washed filters that still look greasy
Healthcare kitchens, like those at hospitals such as Bicester Community Hospital (about 1.8 miles south), often cook for long hours, which puts them in BESA’s heavier-use bands.
