How we handle grease filter exchange in Thorney Island
Good filters only work when they fit properly. Bent, damaged or missing filters leave gaps and every filter is checked when we swap them. We point out any that need replacing. If you have staff short of time to wash filters and damaged filters letting grease past, we can help.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. We agree access and timings in advance.
Think of the report as the system’s health record: a dated account with photos of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Signs you need grease filter exchange in Thorney Island
Repeated removal and washing takes its toll on filters. Damaged filters do not sit flush and grease passes round them.
These are the problems we see most often:
- Grease filters clogged with grease
- Filters that leave gaps in the canopy
- A greasy plenum behind the filters
- Filters that come out of the sink still dirty
Volunteers running a hall kitchen near The Parish Church of St Nicholas, or anywhere in Thorney Island, may not know when the extract was last cleaned, and a grease test settles it.
Questions to ask before you book
- What hours they’ll be on site
- Whether the quote shows VAT
- How areas they can’t reach will be recorded
- Whether a survey comes first
What we do, step by step
When we arrive, we check the system against the survey or the photos you sent. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes anything from a few minutes to an hour or so, depending on the number of filters. We agree a date with you, plan the drive to Thorney Island and turn up when the site is quiet.
- We count and measure the filters in every canopy.
- A change schedule is agreed to match the kitchen’s cooking hours.
- On each visit, the dirty filters come out of the canopy.
- Clean filters go straight back in, seated properly with no gaps.
- Anything we notice, such as bent filters or a dirty plenum, is pointed out.
How to prepare
- Clear loose items from the work area
- Plan for cooking equipment or plant to be off before we arrive
- Mention any sign-in, permit or induction we need
Getting a quote
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before any work starts.

Why deal with it now?
Clogged filters choke the extract. Heat and fumes hang in the kitchen, and the fan works harder to pull air through. Keeping filters clean keeps the extract working properly. Rural sites cannot always move to another kitchen or room when something fails.
Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you are not sure what’s needed, call 0345 646 2711 or use the quote form for straight advice and a fixed quote.

Grease, kitchens and Thorney Island
At about 1 mile from the coast, Thorney Island is close enough for sea air to matter. Metal on the roof weathers faster close to the coast, and the extract fan and cowl are no exception. Food Standards Agency data counts about 6 restaurants, cafés and works canteens within roughly a mile and a half of the centre of Thorney Island. Clogged filters slow the airflow, and busy kitchens like these clog them fast. Thorney Island is covered by West Sussex 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.
A hospital like Havant War Memorial Hospital, about 3.2 miles north-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day. If you look after a school kitchen, at a school such as Thorney Island Community Primary School or anywhere near Thorney Island, the holidays are the usual time for a TR19® clean.
Thorney Island is about 4 miles south-east of Havant, in West Sussex. We carry out grease filter exchange for commercial premises of every kind in Thorney Island and the rest of West Sussex. Thorney Island is one of 371 places in West Sussex where we work for commercial clients. There’s also a page for Portsmouth, about 7 miles away.

Aftercare tips
Simple habits between visits make a real difference. We recommend:
- Don’t refit a filter that is bent
- Do not let the full clean slip because filters are changed
- Make sure no filter is left out
- Always run the extract while cooking
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. A clean set right away cuts the grease in the canopy, and it’s worth checking the plenum too.
In-house cleaning or a specialist?
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.

Common questions in Thorney Island
Who carries out food hygiene inspections in Thorney Island?
That is Chichester council, whose environmental health officers carry out food hygiene inspections in Thorney Island. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Which fire and rescue service is responsible for Thorney Island?
Thorney Island is in the area of West Sussex Fire and Rescue Service. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
What happens if you can’t reach some of it?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
What does TR19 mean?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Will we have to stop cooking for a filter change?
Not for long, and we can time it to avoid service. Cooking shouldn’t happen with the filters out so the swap is done promptly.
Can you come out in an emergency?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we will talk you through the next steps.
Where do the greasy filters go?
The greasy set leaves with us for cleaning, so your staff do not have to wash them. A clean set is fitted in their place.
Can you set up regular visits?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.
