Grease filter exchange in Fifield
Grease filters are the first line of defence in a kitchen extract. Their job is to stop grease getting further into the system and they do it best when they’re clean. Our grease filter exchange service swaps dirty filters for clean ones on a schedule. The work covers baffle filters, island canopies and school and hospital kitchens, and people most often call us about damaged filters letting grease past and filter washing that keeps being missed.
In a small place like Fifield, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. We agree access and timings in advance.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Leave it or put it right?
Dripping canopies and greasy smells often start with the filters. Drips land on surfaces and equipment below, which an EHO may well notice. Rural sites can’t always move to another kitchen or room when something fails.
Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at, and you’ll get one fixed quote.

For landlords and multi-site operators
Keeping records across a portfolio is half the battle. Each visit ends with a dated report and photos, ready to show insurers, fire officers or EHOs.
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.
Different parts, different methods
Busy restaurant and pub kitchens
Heavy cooking means more grease reaching every part of the system. Changing them on time protects the ducts behind.
The plenum
Heavy grease in the plenum often follows clogged or missing filters or that the next TR19 clean is due.

Fifield kitchens: local notes
Fire safety in Fifield falls to Oxfordshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. In Fifield, food businesses are inspected by environmental health officers from West Oxfordshire council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Keeping each certificate and photo report on file helps show the extract is looked after.
Church and community hall kitchens, near Church of St John the Baptist or anywhere around Fifield, are easy to forget, but their extracts collect grease like any other.

What we’re called out for in Fifield
Missing filters are more common than you’d think. A missing filter leaves an open route into the system and on into the ductwork.
Keep an eye out for these warning signs:
- A canopy running with filters missing
- Filter washing that keeps being missed
- Filters so greasy the air can barely pass
- Grease dripping from the canopy
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Fifield is Moore Cottage Hospital, about 4.6 miles west.
Questions to ask before booking
- Whether inaccessible sections are listed on the report
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether the work can be done while the site is closed
- What’s included in the scope, part by part
What a clean won’t put right
It’s worth knowing the limits before booking:
- Odours from the discharge that filters will not stop
- A fan that’s failing or too weak for the system
- Greasy ducts and risers that a filter change will not reach
If you are not sure, just give us a ring on 0345 646 2711 or email us and we’ll give you a straight answer before booking.

FAQs for Fifield
Do you work overnight in Fifield?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Fifield needn’t be disturbed. Your opening times are the first thing we ask for.
Who carries out food hygiene inspections in Fifield?
Food hygiene inspections in Fifield are carried out by West Oxfordshire council. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Do you deal with bent or broken filters?
A badly damaged filter should be replaced. We will tell you which ones and why when we find them.
Which kinds of sites do you work on?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
Is TR19 a legal requirement?
No. The law sets the duty, and TR19® is the recognised benchmark for meeting it. Under the Fire Safety Order 2005, the responsible person must reduce fire risk, and without records, many insurers may refuse or reduce a claim.
How often should grease filters be changed?
It varies from kitchen to kitchen. We look at your cooking and set an interval to match and can change if your kitchen gets busier.
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 in shared buildings more than one person can have duties. If you’re not sure, check your lease and fire risk assessment.
Is there a survey before the work?
Yes, always. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
How we price grease filter exchange
We quote each job individually. These are the things that affect it:
- How easy every part is to reach
- The size of the system
- What state the system is in
- When the work can happen, such as evenings, overnight or weekends
What you pay depends on the size of the system, the condition it’s in and access to every part of it. We give you a fixed price before work begins, so you know where you stand.
Helping us quote
What to send for a quote:
- The postcode and the type of business
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Any access panels or hatches you can see
- Any previous report or certificate
The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
What we do, step by step
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. Most of the time goes on the work itself, and that takes anything from a few minutes to an hour or so, depending on the number of filters. Rural roads and tight entrances are worth telling us about before a visit to Fifield.
- We record the number, size and type of your filters.
- We set the interval with you.
- On each visit, we remove the greasy filters.
- Clean filters go in and we check they sit snugly.
- We take the greasy set away and confirm the next date.
Preparing for the visit
- Let us know about permits to work or site inductions
- Have your last certificate or report to hand
- Allow time for equipment near the work to be turned off and cool down
