Grease filter exchange for kitchens and businesses in Hethe
Grease filters are the first line of defence in a kitchen extract. They catch grease before it reaches the plenum and ductwork and they do it best when they’re clean. With grease filter exchange, clean filters replace greasy ones at regular intervals. Typical jobs include gaps where filters have been removed and smoke and heat lingering under the hood, across restaurants and pubs, baffle filters and school and hospital kitchens.
In a village or hamlet like Hethe, the kitchens that need extract cleaning are normally a pub, a school, a care home or a hall kitchen, wherever there is one. Every one of them still needs its extract kept clear of grease, whatever the size of the place.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

Why it’s worth doing now in Hethe
A filter exchange is a few minutes; a choked extract affects a whole service. It’s one of the simplest parts of looking after the system, and one of the easiest to let slip. Systems in rural buildings are often out of sight and out of mind.
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.

Grease, kitchens and Hethe
Hethe sits within the area of Oxfordshire 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. In Hethe, food businesses are inspected by environmental health officers from Cherwell council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A dated certificate in the maintenance file answers the question before it’s asked.
If you run catering at a healthcare site, such as a hospital like Bicester Community Hospital about 4.6 miles south, the extract may need cleaning more often than a part-time kitchen. If you run a church or community hall kitchen, near Church of St Edmund and George or elsewhere in Hethe, its extract still collects grease from every lunch and event. Term dates shape school work: for a school like Fringford Church of England Primary School, an extract clean fits neatly into a half-term or summer break.
Hethe is about 4 miles north of Bicester, in Oxfordshire. From the centre of Hethe to the outskirts, we cover grease filter exchange for every kind of premises, from small sites to large estates. Our Oxfordshire coverage runs to 443 places, Hethe among them. Oxford is in our area too, around 15 miles away.

What your team can do, and what needs us
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
Your questions about grease filter exchange in Hethe
Can you get to a site in Hethe?
Yes. Hethe is within the area we cover across London and the South East. Photos of the system and directions to the site help us plan the visit.
Which council inspects kitchens in Hethe?
Kitchens in Hethe are inspected by Cherwell council’s environmental health officers. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
Can damaged filters stay in the canopy?
Each filter is looked at when we exchange. Any that are bent or damaged are flagged since a poor fit lets grease past.
Do you offer emergency callouts?
Yes. There’s a 24/7 emergency line, for problems that cannot wait. Call us any time and explain what’s happened.
Does the report say when we need you again?
Yes. The recommended date is on the report. BESA’s minimum intervals for kitchen extracts range from 3-monthly for heavy use to 12-monthly for light use, and fire dampers need testing at least once a year.
Do you work with multi-site operators?
Yes. Tell us the addresses and what each needs and we’ll quote them together.
Do you take the used filters away?
We take them away. That is the point of an exchange: you always have a clean set fitted, with no washing for your team.
What do you do with what you remove?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. We don’t leave it behind.
Managing agents and facilities teams in Hethe
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
The process
We start by comparing what we find with the survey or your photos. If anything is different, we talk it through with the person on site before carrying on. From there, it takes a few minutes per canopy, longer for a large kitchen with several canopies. Rural roads and tight entrances are worth telling us about before a visit to Hethe.
- First, we check the canopies and the filters in them.
- Any damaged or missing filters are noted.
- Greasy filters are swapped for clean ones.
- The filters are checked for fit before we go.
- Anything that needs attention, such as a greasy plenum, is pointed out.
Getting ready for the visit
- Tell us the best time to work, such as after service or at a weekend
- Mention any sign-in, permit or induction we need
- Mention any locked doors, roof access or ceiling voids
Getting a quote
For a fixed quote, give us a ring on 0345 646 2711, or send details by email and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We typically come back within one working day.
Advice
Between visits
Once we’ve finished, these simple steps help:
- Book full TR19 cleans alongside filter changes
- Clear anything stored on or near the canopy
- Watch for grease drips between visits
- Keep canopy surfaces wiped down
We tell you if we spot anything in the canopy that needs attention. It can be a sign that a full TR19® clean is due, and we can arrange it.
Filters that are left too long stop protecting the system. A regular cycle keeps the rest of the system cleaner until the next TR19 clean.
