Grease filter exchange for kitchens and businesses in Bishop's Stortford
The filters in the canopy are the first thing cooking vapour meets. Their job is to stop grease getting further into the system, but only while they’re reasonably clean. Our grease filter exchange service swaps dirty filters for clean ones on a schedule. If you’re dealing with filters so greasy the air can barely pass and hand-washed filters that still look greasy, we can help.
Kitchens in towns like Bishop's Stortford are often in older buildings that were never designed for them, which can mean awkward duct routes, long flat runs and not enough access panels. Where the duct cannot be reached, new panels can be fitted, and anything left uncleaned is recorded on the report.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Keeping the system healthy
A little care between visits keeps the system in better shape. We recommend:
- Clean the canopy surfaces regularly
- Report damaged filters so they can be replaced
- Watch for grease drips between visits
- Keep the canopy clear for exchange visits
There’s no waiting: the canopy is ready as soon as the clean set is fitted. We take the greasy filters with us for cleaning.
If filters are already dripping, they’re overdue. Changing them now reduces the fuel above the cooking, and it’s worth checking the plenum too.
Grease filter exchange in Bishop's Stortford: the local picture
The FSA’s data shows about 26 bars, pubs and nightclubs registered in Bishop's Stortford and the streets around it, up to about 1.5 miles out. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Hertfordshire Fire and Rescue Service covers Bishop's Stortford. 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. It’s East Hertfordshire council that sends environmental health officers to food businesses in Bishop's Stortford. 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.
For schools such as St Michael's Church of England Primary School, kitchen extract cleaning is typically booked for the holidays, when the canteen is closed. Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Bishop's Stortford is Herts and Essex Hospital, about 0.8 miles east.

What else we do in Bishop's Stortford
In-house cleaning or a specialist?
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We’ll take a look and send you a fixed quote.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
When to call us in Bishop's Stortford
Long cooking hours in Bishop's Stortford or anywhere else mean more grease on the filters. Heavy daily use means fast build-up so changes need to come round sooner.
Any of these means the system needs a check-up:
- Grease filters clogged with grease
- Smoke and heat lingering under the hood
- Staff short of time to wash filters
- Grease building up behind the canopy filters
Where a hall near Church of St Michael, or anywhere in Bishop's Stortford, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

For landlords and multi-site operators
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side, and the report can go to both.
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
What affects the cost of grease filter exchange
The survey tells us what the work involves. We look at:
- How many systems or sites are involved
- Working hours and out-of-hours timing
- Whether we need access equipment or extra panels
- Any permits to work or inductions
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.
What we need to know
A few details help us quote accurately. When you get in touch, it helps to send:
- The paperwork from the last visit, if you have it
- The postcode and the type of business
- The times we could work without disrupting the site
- Any symptoms, from odd noises to smells or leaks
Here’s what helps us quote: the address, the type of site and when it’s open, photos of the system and the last certificate or report, if there is one. Then call us on 0345 646 2711, or email photos.
What happens on the day
We are used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. On site, the work takes a few minutes per canopy, longer for a large kitchen with several canopies. The more we can see of the system beforehand, the smoother the visit to Bishop's Stortford will be.
- First, we record the size, type and number of filters in each canopy.
- We agree a schedule that suits how much the kitchen cooks.
- Each visit starts with the used filters being removed.
- We fit clean filters and check they sit snugly in the housing.
- We flag any damaged filters or anything wrong with the canopy.
Before we arrive
- Let us know when the site is closed or quiet
- Name a contact who can let us in at the agreed time
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
How to get a quote
The quickest way to a quote is to send photos: 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.

FAQs for Bishop's Stortford
Can a school canteen extract in Bishop's Stortford be done out of term time?
Yes. Half-terms and the summer break are the natural time for school work. Food Standards Agency records list about 23 schools, colleges and universities with registered kitchens within about a mile and a half of Bishop's Stortford. Booking early in the term gives the best choice of holiday dates.
Can you work in Bishop's Stortford outside opening hours?
Yes, we can come after you close and finish before you open. It means the site in Bishop's Stortford keeps running as normal. Let us know the hours you are closed and we will book within them.
Does a filter exchange replace TR19 cleaning?
No. Clean filters help keep grease down, but the ducts and plenum still need cleaning at the right interval.
Does the report say when we need you again?
Yes. The interval depends on how much the system is used and what we find and the report sets out why.
How long does the visit take?
We will confirm the time with your quote. In most cases, the work takes a short visit, depending on how many filters the canopies hold.
Can you look after several sites?
Yes. Tell us the addresses and what each needs and we will quote them together.
What types of premises do you cover?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
How much notice should we give?
The more notice, the better, particularly for night and weekend visits. Quotes normally come back within one working day, and emergencies are covered by our 24/7 line.
What a clean will not put right
To be straight with you, some problems need a different fix:
- A noisy or failed extract fan
- An extract that was undersized from the start
- A heavily greased plenum or canopy, which needs cleaning to TR19
