Grease filter exchange in Northolt

A filter service works alongside TR19® cleaning, not instead of it. Fresh filters help limit what gets into the ductwork, but some grease still passes through as vapour. That’s why the whole system still needs cleaning to TR19 at the right interval. The work covers wall canopies, restaurants and pubs and baffle filters, and the jobs we see most are a canopy that drips grease and grease building up behind the canopy filters.

In a London area like Northolt, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. A duct fire there can reach parts of the building far from the range, so a regular TR19® clean protects everyone in it.

We have been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Common problems we fix in Northolt

Long cooking hours in Northolt or anywhere else mean more grease on the filters. Heavy daily use means fast build-up, so it needs more frequent changes.

These are the problems we see most often:

  • A canopy running with filters missing
  • Staff short of time to wash filters
  • Grease collecting in the filter channels
  • Weak extraction at the canopy

A hospital like Clementine Churchill Hospital, about 2 miles north-east, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

Questions to ask before you book

In-house cleaning or a specialist?

If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.

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.

Why deal with it now?

Dripping canopies and greasy smells often start with the filters. Left, it ends up on equipment, food areas and staff, which an EHO may well notice. Every month a London system goes without attention adds to what has to be done later.

What you pay reflects the actual work. That is why every job is surveyed first, and the price is agreed before any work starts.

Why us?

  • In business since 2009
  • Fixed quotes, normally within one working day
  • A written report with photos after each visit
  • One number for every site across the South East and London

FAQs for Northolt

Who enforces fire safety at workplaces in Northolt?

Northolt 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.

Can you clean school kitchen extracts in Northolt during the holidays?

Yes, holiday work suits schools best. The FSA’s register shows about 40 schools and colleges with food registrations within roughly a mile and a half of Northolt. Send us your term dates when you call us on 0345 646 2711 or email us, and we will fit the work in.

How do you keep the site clean during the work?

Floors and surfaces near the work are sheeted before any work starts, and anything we remove is contained. At the end, the area is cleaned down.

What paperwork should we keep on file?

The reports and certificates from each visit, plus your own logs. Insurers, fire officers and EHOs may all ask to see them, so keep them where they can be found quickly.

What’s the right interval for changing filters?

It depends on how much and what the kitchen cooks. Kitchens that fry and grill all day need changes more often than lighter ones. We agree the interval with you.

How long will you be on site?

That depends on how much there is to do, but for many sites it takes a short visit, depending on how many filters the canopies hold. We’ll give you a better idea when we quote.

What happens if you can’t reach some of it?

Anything we cannot reach goes on the report, with a note of where it is, and we tell you what would make it reachable, such as extra access panels in ductwork.

How far ahead should we book?

It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.

Honest limits

Not every problem is solved by grease filter exchange, and we’d rather say so up front. It doesn’t solve:

  • Grease behind the filters that a swap cannot remove
  • Cooking smells reaching neighbours, which need odour control
  • A canopy that does not capture the vapour properly

Not sure which it is? You can call 0345 646 2711, or send details by email and we will tell you honestly.

Managing agents and facilities teams in Northolt

Whether it’s one building or many, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with photos.

If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so each one has its own record.

What we do, step by step

At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. The visit takes less than an hour in most kitchens. A name and number for whoever controls access to the building in Northolt saves time on the night.

  1. The filters in each canopy are measured and counted.
  2. An exchange schedule is agreed to suit your cooking.
  3. The dirty set is lifted out.
  4. Clean filters go in and we check they sit snugly.
  5. We take the greasy set away and confirm the next date.

Getting ready for the visit

  • Tell us where we can park and unload
  • Mention any sign-in, permit or induction we need
  • Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

Advice

How the job changes from site to site

Mesh filters

Mesh filters use layers of metal mesh to trap grease. They clog quickly in a busy kitchen and need frequent attention.

Busy restaurant and pub kitchens

In a busy kitchen, filter washing is easy to skip. An exchange service takes it off the rota.

Northolt kitchens: local notes

There are about 159 cafés, restaurants and staff canteens and about 76 sandwich bars and takeaways across Northolt and its immediate surroundings (about a mile and a half), according to the Food Standards Agency’s register. Clogged filters slow the airflow, and busy kitchens like these clog them fast. London Fire Brigade covers Northolt. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. London jobs typically start after the last service, with loading and roof access agreed with the building first.

Church and community hall kitchens, near St Richard's Church or anywhere around Northolt, are easy to forget, but their extracts collect grease like any other. For schools such as Willow Tree Primary School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.
