Grease filter exchange in Nether Wallop, done properly
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 blocked baffle filters and damaged filters letting grease past, across restaurants and pubs, wall canopies and island canopies.
In a small place like Nether Wallop, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.
Every visit ends with a written report and photos, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Why it’s worth doing now in Nether Wallop
Changing filters on schedule costs far less disruption than a blocked extract. It’s one of the simplest parts of looking after the system, and one of the easiest to let slip. In a small place like Nether Wallop, a system that fails can take a site out of use.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are unsure, phone us on 0345 646 2711 or send us an email for straight advice and a fixed quote.

How the job changes from site to site

Busy restaurant and pub kitchens
Kitchens that fry and grill all day load their filters fast. They often need the shortest exchange interval.

Aftercare tips
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Keep the extract on whenever the range is in use
- Don’t refit a filter that is bent
- Keep canopy surfaces wiped down
- Look out for drips from the canopy
If the plenum behind the filters looks greasy, we say so. It can be a sign that a full TR19® clean is due and we can book that in.
If filters are already dripping, they’re overdue. A clean set straight away cuts the grease in the canopy and the plenum may need a clean as well.
What affects the cost of grease filter exchange
Sites vary more than people expect. The main factors:
- The condition we find in the survey

- When the site is open and when it’s quiet

Advice
What your team can do, and what needs us
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.

FAQs for Nether Wallop
Who enforces fire safety at workplaces in Nether Wallop?
Fire safety enforcement in Nether Wallop is handled by Hampshire and Isle of Wight Fire and Rescue Service. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Which council inspects kitchens in Nether Wallop?
That’s Test Valley council, whose environmental health officers carry out food hygiene inspections in Nether Wallop. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
What should go in our maintenance log?
Everything that shows the system is looked after: our reports and photos, any certificates and your in-house logs. One maintenance log per site keeps it simple.
Which grease filters does the service cover?
Baffle filters and mesh filters. Mention how many canopies you have when you get in touch, or we will check on the first visit.
What is TR19?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Can we skip TR19 cleans if the filters are changed regularly?
It does not. Some grease passes the filters as vapour and settles in the ducts, so the full system still needs cleaning to TR19.
Do I get a report after the visit?
Yes. You get a written report with photos after every visit, covering the work, any areas we couldn’t access and the recommended next date. Kitchen extract cleans to TR19® Grease also get a certificate through the BESCA Vent Hygiene Elite portal.
Will we have to stop cooking for a filter change?
A filter change is quick and can be timed around service. The canopy shouldn’t be used without filters, so we swap them in one go.
Signs you need grease filter exchange in Nether Wallop
Filters get bent and damaged with handling. Damaged filters do not sit flush and grease passes round them.
Keep an eye out for these warning signs:
- Poor airflow through the filters
- Bent or damaged filters that do not sit properly
- A canopy that drips grease
- Hand-washed filters that still look greasy
School kitchens, at schools like Wallop Primary School for example, are usually cleaned in the holidays so no lunches are lost.
