About our grease filter exchange in Warsash
We run grease filter exchange for all kinds of kitchens in Warsash, whether there’s one canopy or many. Visits can be timed around your service so nobody has to stop cooking. If you are dealing with grease left in baffles after washing and damaged filters letting grease past, we can put it right.
For a smaller kitchen near Warsash, a TR19® clean is the same job as anywhere: canopy, filters, plenum, duct, fan and discharge. We plan the visit around your hours, with the journey sorted in advance.
The paperwork matters as much as the work. Each visit is written up with pictures, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

What else we do in Warsash
What we do, step by step
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool first, and floors and nearby surfaces are sheeted. The work itself takes a few minutes per canopy, longer for a large kitchen with several canopies. Your opening hours decide when we come to Warsash, not ours.
- 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.
- We take the greasy set away and confirm the next date.
Before we arrive
- Have your last certificate or report to hand
- Clear the space around the work
- Make sure equipment near the work can be switched off and left to cool

Advice
Common problems we fix in Warsash
The type of cooking matters. Frying, grilling and chargrilling produce far more grease than steaming or baking, so the right exchange interval varies.
It’s time to book a visit if you see:
- Filters that come out of the sink still dirty
- Blocked baffle filters
- Grease building up behind the canopy filters
- Damaged filters letting grease past
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Coldeast is the nearest hospital to Warsash, about 0.9 miles north.
Questions to ask before you book
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether the work can be done while the site is closed
- Whether the price is fixed
- When the next visit should be, and why
Common questions in Warsash
Does the sea air around Warsash make a difference to grease filter exchange?
It can. Salt air reaches Warsash, which is within about 1 mile of the coast, and it speeds up rust. Outdoor metalwork near the sea is worth inspecting at each visit.
Which fire authority looks after Warsash?
It’s Hampshire and Isle of Wight Fire and Rescue Service, which covers Warsash. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Do you deal with bent or broken filters?
Filters that no longer fit properly need replacing. We will tell you which ones and why when we find them.
Are you fully insured?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
Do I get a report after the visit?
Yes. It’s the record insurers and inspectors ask to see: a dated report with pictures, listing the work and any areas we couldn’t reach.
Do you offer maintenance contracts?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. The report from each visit recommends the next date.
Do you cover Warsash?
Yes. We work in Warsash and across Hampshire, within our South East and London area. To book, call us on 0345 646 2711 or drop us a line.
How much notice should we give?
That depends on the slot you want and the size of the job. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.
In-house cleaning or a specialist?
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That’s our job.
Grease filter exchange in Warsash: the local picture
The coast is only about 1 mile from Warsash. Salt air speeds up corrosion of roof-level fans, discharge cowls and their fixings. There are about 41 restaurants, cafés and works canteens and about 7 sandwich bars and takeaways within roughly a mile and a half of the centre of Warsash, according to the Food Standards Agency’s register. Any of those kitchens with a canopy relies on its filters to catch grease before it reaches the duct. Fire safety in Warsash falls to Hampshire and Isle of Wight Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.

Church and community hall kitchens, near Church of St Mary or anywhere around Warsash, are easy to forget, but their extracts collect grease like any other.

What happens if it’s left?
Washing filters in-house is an option for kitchens in Warsash, and that can work if it’s done thoroughly and on time. When it doesn’t happen reliably, an exchange makes it automatic. Light use slows the build-up but does not stop it.
The cost depends on the size of the system, the condition it’s in and access to every part of it. You get a fixed price before we start, so you know where you stand.

Aftercare tips
Good habits slow the build-up between visits. Our tips:
- Keep the extract on whenever the range is in use
- Book full TR19 cleans alongside filter changes
- Make sure no filter is left out
- Report damaged filters so they can be replaced
Between visits, check that every filter is still in place. Gaps let grease into the plenum so tell us if you need a replacement.
Filters that are left too long stop protecting the system. Getting onto a regular exchange now keeps grease out of the plenum and ductwork between full cleans.
