Portsmouth · Grease filter exchange
Grease filter exchange in North End, Portsmouth
A scheduled grease filter exchange, swapping dirty canopy filters for clean ones for businesses, landlords and public buildings in North End. CHAS, SafeContractor and ISO 9001, and fully insured.
- Grease collecting in the filter channels
- Smoke and heat lingering under the hood
- Filters so greasy the air can barely pass
Why deal with it now?
Once filters are saturated, more grease gets past them. The ductwork then loads up faster, and grease may build up faster than the cleaning interval allows. When a site near North End shuts unexpectedly, the people who rely on it notice at once.
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll explain each part.

Grease filter exchange in North End, done properly
Cleaning filters by hand takes staff time and is easy to put off. An exchange service means clean filters arrive and greasy ones leave and the canopy is refilled right away. If you have bent or damaged filters that don’t sit properly and filters that come out of the sink still dirty, we can put it right, from baffle filters, wall canopies and mesh filters onwards.
Around a smaller place like North End, kitchen extracts tend to belong to pubs, cafés, takeaways and school or care home kitchens. Quieter kitchens still collect grease in the duct, just more slowly, so the interval is set by hours of use and grease readings.
Good records are part of the job. 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. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

For landlords and multi-site operators
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
Whether it’s one building or many, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
What else we do in North End
What grease filter exchange cannot fix
In fairness, some problems need a different fix:
- Extraction problems caused by the fan rather than the filters
- An extract that was undersized from the start
- Cooking smells reaching neighbours, which need odour control
If in doubt, phone us on 0345 646 2711 or send us an email and we will say what we think.
Parts of the system we cover
- School and hospital kitchens
- Restaurants and pubs
- Wall canopies
- Mesh filters
- Baffle filters
- Island canopies
What happens on the day
We are used to working while the site is closed. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. On site, the work takes a few minutes per canopy, longer for a large kitchen with several canopies. Visits to a place like North End are planned ahead, so we arrive with what the survey says the job needs.
- First, we check the canopies and the filters in them.
- Any damaged or missing filters are noted.
- We exchange the dirty filters for a clean set.
- The filters are checked for fit before we go.
- Anything that needs attention, such as a greasy plenum, is pointed out.
Preparing for the visit
- Clear the space around the work
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Tell us where we can park and unload

FAQs for North End
Do you clean school canteen extracts around North End out of term?
Yes, out-of-term visits are normal for schools. There are about 32 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of North End. Send us your term dates when you call us on 0345 646 2711 or email us, and we will fit the work in.
Do you work in villages like North End?
Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.
Is there a cleaning option for the filters we have?
We can. Cleaning your existing filters is an option, and others prefer a straight swap. Either way, the canopy isn’t left without filters during service.
How long will you be on site?
On site, it takes a few minutes per canopy, longer for a large kitchen with several canopies. Larger systems naturally take longer, and the quote will say how long.
Are you accredited?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.
Will you tell us when the next visit is due?
Yes. The interval depends on how much the system is used and what we find and the report sets out why.
What if some of our filters are damaged?
Filters that no longer fit properly need replacing. We’ll show you which ones on the visit.
Does a filter exchange replace TR19 cleaning?
It is not. Clean filters help keep grease down, but the ducts and plenum still need cleaning at an interval set by risk assessment.
What the work involves, part by part
Baffle filters
When baffles fill with grease, less air gets through. Swapping them for a clean set restores it.
Canopy filter housings
The trough or channel under the filters fills with grease. If it needs attention, we will tell you.
Keeping the system healthy
Once we have finished, these simple steps help:
- Don’t let the full clean slip because filters are changed
- Keep the canopy clear for exchange visits
- Wipe the outside of the canopy as part of daily cleaning
- Keep every filter in place during service
The next exchange is already in the diary. If the kitchen gets busier, the interval can be shortened to match.
Damaged filters leave gaps in the defence. Sorting them now keeps grease where it can be caught.
In-house cleaning or a specialist?
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Kitchen extracts in North End
Sea air reaches North End, which sits within about 1 mile of the coast. Near the sea, the fan and discharge at the top of a kitchen extract corrode faster than they would inland. The FSA’s data shows about 54 pubs, bars and clubs and about 6 hotels and B&Bs registered in and around North End, up to about a mile and a half out. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Fire safety in North End falls to Hampshire and Isle of Wight Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
Church and community hall kitchens, near St. Mark’s or anywhere around North End, are easy to forget, but their extracts collect grease like any other. If you run catering at a healthcare site, such as a hospital like Royal Portsmouth Hospital about 1.2 miles south, the extract may need cleaning more often than a part-time kitchen. For schools such as Corpus Christi Catholic Primary School, kitchen extract cleaning is typically booked for the holidays, when the canteen is closed.
