Southampton · Grease filter exchange
Grease filter exchange in Bitterne, Southampton
Grease filter exchange across Bitterne and nearby, timed so the site keeps working and signed off in writing with photos.
- Gaps where filters have been removed
- Smoke and heat lingering under the hood
- Filter washing that keeps being missed
Looking after it afterwards
No system stays clean for ever, but care slows the build-up. Our tips:
- Always run the extract while cooking
- Keep every filter in place during service
- Clean the canopy surfaces regularly
- Keep the canopy clear for exchange visits
The canopy looks cleaner and the air moves better from the moment they’re fitted. Always run the extract during cooking so the filters do their job.
If filters are already dripping, they’re overdue. Changing them now reduces the fuel above the cooking and the plenum may need a clean as well.
Grease filter exchange for kitchens and businesses in Bitterne
Across Bitterne, our filter exchange suits restaurants, pubs, cafés, schools, care homes and other kitchens, from a single canopy to several. We can come before or after service, so cooking is not interrupted. The work covers island canopies, school and hospital kitchens and baffle filters, and people most often call us about staff short of time to wash filters and grease filters clogged with grease.
Size does not change the work: a kitchen in a place like Bitterne gets the whole system cleaned, canopy to discharge. The visit is booked around your opening hours, and the journey is planned ahead.
The paperwork matters as much as the work. You get a written report with photos after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

Why deal with it now?
In Bitterne, as everywhere, a filter service isn’t a substitute for TR19 cleaning. They do help keep the system in better shape between cleans, and that shows when the next clean comes round. It’s easy to lose track of when the work was last done on a quieter site.
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. The price is fixed before we start.

Bitterne questions
Which fire authority looks after Bitterne?
Bitterne is in the area of Hampshire and Isle of Wight Fire and Rescue Service. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Can you clean school kitchen extracts in Bitterne during the holidays?
Yes. Half-terms and the summer break are the natural time for school work. Food Standards Agency records list about 41 schools, colleges and universities with registered kitchens within about a mile and a half of Bitterne. Just phone us on 0345 646 2711, or send details by email with your term dates and we will plan around them.
Will you tell us when the next visit is due?
Yes. We put a recommended next date on the report. BESA’s minimum intervals for kitchen extracts range from 3-monthly for heavy use to 12-monthly for light use, and fire dampers need testing at least once a year.
Where does the waste go?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on, so it does not spread.
Can we skip TR19 cleans if the filters are changed regularly?
No, the two work together. A TR19® clean deals with the whole system and comes with a certificate and photo report.
Do you cover Bitterne?
Yes. Our area takes in London and the counties of South East England, Bitterne included.
Can damaged filters stay in the canopy?
We check every filter at each visit. We tell you about any that are damaged, because gaps let grease into the plenum.
What paperwork should we keep on file?
The reports and certificates from each visit, plus your own logs. They’re what an insurer, fire officer or EHO may ask for, so keep them where they can be found quickly.

Fixed quotes for grease filter exchange in Bitterne
The diagnosis comes before the price. We look at:
- The number of sites or systems
- What state the system is in
- Access, including roofs, risers and ceiling voids
- A single visit or a regular plan
Working hours, access and the scale of the site can all change the price. We take each of them into account, and the price is fixed before work begins.
What we need to know
Many jobs can be priced from photos and some basics. Useful things to send:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Photos showing the whole system and its surroundings
- Any previous report or certificate
- The site address and the type of premises
Here’s what helps us quote: the address, the type of site and when it’s open, pictures of the system and the last certificate or report, if there is one. Once you have those, ring 0345 646 2711, or send details by email.
What the work involves, part by part
Baffle filters
Baffle filters use overlapping metal blades that force the air to change direction. Grease is thrown out of the airstream and collects on the baffles.
School, care home and staff kitchens
Lighter kitchens can often go longer between changes. The interval is set to fit.
Signs you need grease filter exchange in Bitterne
What a kitchen cooks affects how fast filters clog. Frying, grilling and chargrilling produce far more grease than steaming or baking so no single schedule suits every kitchen.
Look out for these warning signs:
- A canopy that drips grease
- Filters left unwashed on busy weeks
- Bent or damaged filters that do not sit properly
- Filters that come out of the sink still dirty
If you run catering at a healthcare site, such as a hospital like Royal South Hants Hospital about 1.5 miles west, the extract may need cleaning more often than a part-time kitchen.

What we do, step by step
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. The visit itself takes anything from a few minutes to an hour or so, depending on the number of filters. In a smaller place like Bitterne, parking is rarely the issue, but tell us about gates, roof access and opening hours.
- We look at the canopies and the condition of the filters.
- We note any filters that are bent, damaged or missing.
- We exchange the dirty filters for a clean set.
- We check the filters are seated and the canopy is ready to use.
- We tell you if the plenum or canopy needs a clean.
How to prepare
- Agree a time when the area can be out of use
- Plan for cooking equipment or plant to be off before we arrive
- Let us know about permits to work or site inductions
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, before work begins.
