Grease filter exchange for kitchens and businesses in Farnborough
A filter service works alongside TR19® cleaning, not instead of it. Clean filters reduce the grease reaching the ducts, but some grease still passes through as vapour. That is why the whole system still needs cleaning to TR19 at the right interval. We’re often asked to deal with a greasy plenum behind the filters and filters that come out of the sink still dirty, on mesh filters, restaurants and pubs and island canopies.
In London, few kitchens can spare a day to close, so extract cleaning in Farnborough is usually done overnight, after the last service. Parking, loading and access to the roof are agreed with the building before the night of the clean.
Nothing is signed off by word of mouth: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

How it works
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. Anything that needs to be off for the work is switched off and left to cool before work begins, and the area around the work is covered and protected. On site, it takes anything from a few minutes to an hour or so, depending on the number of filters. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Farnborough.
- We count and measure the filters in every canopy.
- Together we set how often the filters should be changed.
- On each visit, the dirty filters come out of the canopy.
- Clean, dry filters are fitted in their place, with no gaps left between them.
- We flag any damaged filters or anything wrong with the canopy.
Preparing for the visit
- Mention any sign-in, permit or induction we need
- Name a contact who can let us in at the agreed time
- Clear loose items from the work area

What else we do in Farnborough
Kitchen extracts in Farnborough
Food Standards Agency records include about 14 pubs and bars within roughly a mile and a half of the centre of Farnborough. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Kitchens in Farnborough get their food hygiene inspections from Bromley council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A TR19® certificate and photo report after each clean gives you a record to show an inspector. London Fire Brigade covers Farnborough. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
A hospital like Orpington Hospital, about 0.9 miles east, is the kind of site where a kitchen may cook for patients, staff and visitors all day. If you run catering at a historic house or estate in the area (Down House is about 2.1 miles south-west), event kitchens in older buildings often have awkward duct runs that need planning. If you run a church or community hall kitchen, near Church of St Giles the Abbot or elsewhere in Farnborough, its extract still collects grease from every lunch and event.
Farnborough is about 2 miles south-west of Orpington, in Greater London. Every kind of commercial site in Farnborough, grease filter exchange is something we can help with. We can work out of hours so the site keeps running. Our Greater London coverage runs to 764 places, and Farnborough is one of them. For sites nearby, see our London page, about 12 miles away.

Questions from Farnborough
Can school kitchens in Farnborough be cleaned in the holidays?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 7 schools and colleges with food registrations within roughly a mile and a half of Farnborough. Just call us on 0345 646 2711, or email photos with your term dates and we’ll plan around them.
Who is the fire and rescue service for Farnborough?
Farnborough is in the area of London Fire Brigade. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Do you take the used filters away?
They leave with us. That is the point of an exchange: clean filters in, dirty ones out and nothing greasy left on site.
Do you survey before quoting?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
Do we need to close the kitchen while filters are changed?
Not for long, and we can time it to avoid service. Cooking shouldn’t happen with the filters out, so we swap them in one go.
What happens to the waste?
It’s contained and taken away. We collect grease, debris and waste water as we go rather than letting it spread.
Is Farnborough in your area?
Yes. Our technicians work in Farnborough, within the South East and London area we cover.
Do you deal with bent or broken filters?
We check every filter at each visit. Any that are bent or damaged are flagged, because gaps let grease into the plenum.
Why act early in Farnborough
Grease dripping from the canopy is a sign the filters can’t hold any more. Left, it ends up on equipment, food areas and staff and that’s the kind of thing inspectors look for. A building in Farnborough may have flats or offices above and alongside, and a fault in the system can affect them too.
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at and we’ll price it together.

Aftercare tips
No system stays clean for ever, but care slows the build-up. Our tips:
- Wipe the outside of the canopy as part of daily cleaning
- Book full TR19 cleans alongside filter changes
- Keep every filter in place during service
- Mention it if the kitchen gets busier
Fresh filters improve airflow at the canopy straight away. Keep the extract running while you cook so the filters do their job.
If filters are already dripping, they’re overdue. A clean set right away cuts the grease in the canopy, and it’s worth checking the plenum too.
Landlords, agents and facilities managers
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
Facilities teams in offices, schools and healthcare sites book us too across Greater London. Work can be phased by floor, building or site around the people who use them.
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.
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. Leave those to us.
What a clean won’t put right
To be straight with you, there are a few things this work won’t fix:
- Extraction problems caused by the fan rather than the filters
- An extract that was undersized from the start
- Odours from the discharge that filters will not stop
If in doubt, call us on 0345 646 2711, or email photos and we will say what we think.
