Grease filter exchange for kitchens and businesses in Southsea
Good filters only work when they fit properly. Bent, damaged or missing filters leave gaps, so we check every one at each visit. Damaged filters are flagged so they can be replaced. Typical jobs include drips falling from the filters onto equipment and damaged filters letting grease past, across restaurants and pubs, mesh filters and baffle filters.
For a pub, café or restaurant in a town like Southsea, losing a day’s trade to cleaning is not an option, so the work is done after service, overnight or on a closed day. By the next service, the kitchen is ready to cook in again.
The paperwork matters as much as the work. You get a written report with pictures after each visit, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

Part by part
Canopy filter housings
The trough or channel under the filters fills with grease. If it needs attention, we will tell you.
The plenum
The plenum is the space behind the filters. Grease that gets past the filters settles there.
Why it’s worth doing now in Southsea
Filters full of grease are fuel sitting right above the cooking. Flames from the range can be drawn up into the canopy, and from there into the duct. Keeping filters clean takes some of that fuel away. A small fault found now is a quick job; the same fault found later can close the site.
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at and we’ll price it together.

Southsea questions
Do you work at weekends in Southsea?
Yes, nights and weekends are routine for us. Your customers, staff or residents in Southsea needn’t be disturbed. Your opening times are the first thing we ask for.
Can you clean school kitchen extracts in Southsea during the holidays?
Yes. Half-terms and the summer break are the natural time for school work. Around Southsea, the Food Standards Agency lists about 35 schools and colleges with registered kitchens within a mile and a half or so. You can call 0345 646 2711, or send details by email with the dates the site is empty.
How much notice do you need?
Earlier is better, particularly for night and weekend visits. We typically quote within one working day, and emergencies are covered by our 24/7 line.
Do you clean filters as well as exchanging them?
Yes, filter cleaning is available. We will check your filters first because bent or damaged ones may need replacing.
How long will you be on site?
The work itself takes a short visit, depending on how many filters the canopies hold. Larger systems naturally take longer, and we’ll tell you what to expect.
Where does the waste go?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. We do not leave it behind.
Does a filter exchange replace TR19 cleaning?
It doesn’t. Filters don’t catch everything, so grease still reaches the ductwork, so the full system still needs cleaning to TR19.
Will you tell us when the next visit is due?
Yes. We put a recommended next date on the report. For kitchen extracts, BESA’s minimum intervals run from every 3 months for heavy use to every 12 months for light use, while fire dampers are tested at least annually.
Grease, kitchens and Southsea
At about 1 mile from the coast, Southsea is close enough for sea air to matter. Salt in the air is hard on rooftop fans, discharge cowls and fixings, so we check them for corrosion as well as grease. Look up Southsea on the FSA’s food hygiene register and you will find about 230 restaurants, cafés and works canteens and about 107 takeaways and sandwich shops within roughly a mile and a half of the centre of Southsea. Any of those kitchens with a canopy relies on its filters to catch grease before it reaches the duct. In Southsea, food businesses are inspected by environmental health officers from Portsmouth council. Extraction counts as kitchen equipment, so its condition can come up on the day. Keeping each certificate and photo report on file helps show the extract is looked after.
School kitchens, at schools like Craneswater Junior School for example, are normally cleaned in the holidays so no lunches are lost. Commuter trade near Fratton station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands.
Southsea is about 2 miles south of Portsmouth, in Portsmouth. Anywhere in PO5, we can take on grease filter exchange. Our Portsmouth coverage runs to 19 places, and Southsea is one of them.
Postcode districts we cover here for grease filter exchange: PO5, PO4 and PO1. You’ll find streets such as Bath Road, Liss Road and Beach Road, and we cover them all for grease filter exchange.

What’s near Southsea
We work in commercial kitchens and buildings around The Festing pub, St Edmund's Catholic School and Mayville High School and the streets around them. The nearest railway station is Fratton station, about 0.8 miles north of the centre. A little further out are St. Mary's Hospital (1 mile north) and Southsea Castle (1 mile south-west). Not far away are Milton Locks.
Common problems we fix in Southsea
Cooking vapour carries grease into the canopy. Much of it is trapped by the filters so they gradually clog until the air can barely get through.
If you notice any of these, it’s worth a diagnosis:
- Filters that leave gaps in the canopy
- Smoke and heat lingering under the hood
- Grease collecting in the filter channels
- Gaps where filters have been removed
A hospital like St. Mary's Hospital, about 1 mile north, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

Managing agents and facilities teams in Southsea
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we will send a fixed quote.
What your team can do, and what needs us
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
The process
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. On site, the work takes a few minutes per canopy, longer for a large kitchen with several canopies. Send us pictures of the system and we can plan most of a visit in Southsea before we arrive.
- We record the number, size and type of your filters.
- We set the interval with you.
- The dirty set is lifted out.
- A clean set is fitted and checked for gaps.
- We take the greasy set away and confirm the next date.
Getting ready for the visit
- Arrange a key holder or contact on site
- Tell us about site rules, permits or sign-in
- Tell us the best time to work, such as after service or at a weekend

How we price grease filter exchange
The quote reflects the site in front of us. We consider:
- The size of the system
- A single visit or a regular plan
- How easy every part is to reach
- The condition of the system
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote, and the price is fixed before work begins.
What to send for a quote
When you contact us, it’s useful to have:
- The times we could work without disrupting the site
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Close-ups of filters, grilles, hatches or access panels
- Wide pictures of the system and the area around it
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To start, call 0345 646 2711 or drop us a line.
