What staff can safely do

Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.

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, which is where we come in.

Grease filter exchange in Northfields

Across Northfields, 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 nobody has to stop cooking. We are often asked to deal with grease building up behind the canopy filters and filters that come out of the sink still dirty, on island canopies, restaurants and pubs and school and hospital kitchens.

In a London area like Northfields, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. Grease in a duct like that is a fire risk to the whole building, not just the kitchen, which is why keeping it clean to TR19® matters.

The report is your system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

How we price grease filter exchange

The survey tells us what the work involves. We look at:

  • How many systems or sites are involved
  • Access, including roofs, risers and ceiling voids
  • Parking and loading at the site
  • Site rules, permits and inductions

What you pay depends on how big the system is, the condition it’s in and how easy it is to reach. We give you a fixed price before we start, so you know where you stand.

What we need to know

To speed up the quote, send us:

  • Anything you’ve noticed, such as smells, noise, drips or poor airflow
  • How we’d reach plant on a roof or in a plant room
  • The postcode and the type of business
  • Close-ups of filters, grilles, hatches or access panels

Quotes are quick. Send a few details and pictures, and we usually reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

How it works

Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes well under an hour for most canopies. Expect the work in Northfields to happen after your last customer leaves, not during trading.

  1. The filters in each canopy are measured and counted.
  2. An exchange schedule is agreed to suit your cooking.
  3. On each visit, we remove the greasy filters.
  4. A clean set is fitted and checked for gaps.
  5. We take the greasy set away and confirm the next date.

Before we arrive

  • Mention any parking or loading restrictions
  • Make sure someone can let us in and lock up afterwards
  • Have your last certificate or report to hand

When it’s something else

We will always give you a straight diagnosis, so here’s what this work can’t put right:

  • Extraction problems caused by the fan rather than the filters
  • Grease deep in the extract system
  • Odours from the discharge that filters won’t stop

If in doubt, ring 0345 646 2711, or email photos and we will say what we think.

Where we work

  • Wall canopies
  • Restaurants and pubs
  • Island canopies
  • Mesh filters
  • School and hospital kitchens
  • Baffle filters

What happens if it’s left?

Clogged filters choke the extract. Heat and fumes hang in the kitchen while the fan strains. A regular exchange keeps the airflow where it should be. London sites work long hours, and the longer a job is left, the bigger it gets.

The price reflects the work, not guesswork. That’s why we survey first, from pictures or on site, and the price is agreed before work begins.

Why Northfields businesses choose us

  • A fixed price before any work starts
  • Every visit written up, with photos
  • One number for every site across the South East and London

Grease filter exchange in Northfields: the local picture

Look up Northfields on the FSA’s food hygiene register and you will find about 444 cafés, restaurants and staff canteens and about 96 takeaways in Northfields and the streets around it, up to about 1.5 miles out. Where they cook under a canopy, the grease filters are the first line of defence and clog quickly. Fire safety in Northfields falls to London Fire Brigade. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. In London, kitchens are typically cleaned overnight, when the kitchen is closed and loading is easier.

Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Ealing Hospital is the nearest hospital to Northfields, about 1.4 miles west. Historic houses near Northfields, such as Boston Manor about 0.5 miles south, are a reminder that older buildings with event kitchens can have long, awkward duct routes. School kitchens, at schools like Mount Carmel Catholic Primary School for example, are typically cleaned in the holidays so no lunches are lost.

Common questions in Northfields

Who inspects food businesses in Northfields?

In Northfields, it’s Ealing council that carries out food hygiene inspections. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.

Can you work in Northfields outside opening hours?

Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. When you give us a ring on 0345 646 2711, or send details by email, mention when the site is quiet.

Can we skip TR19 cleans if the filters are changed regularly?

It doesn’t. Filters do not catch everything, so grease still reaches the ductwork, so the full system still needs cleaning to TR19.

Do you deal with bent or broken filters?

Damaged filters do not seat properly and let grease through. We flag any we find so they can be replaced.

How much notice do you need?

The more notice, the better, especially for out-of-hours work. We typically quote within one working day, and emergencies are covered by our 24/7 line.

Do you work in Northfields?

Yes. Our area takes in London and the counties of South East England, and that includes Northfields.

How often should grease filters be changed?

There’s no single answer. We look at your cooking and set an interval to match and can change if your kitchen gets busier.

How long does the visit take?

The work itself 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.

Managing agents and facilities teams in Northfields

Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.

Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.

Different parts, different methods

Mesh filters

Mesh filters use layers of metal mesh to trap grease. In a busy kitchen, mesh soon blocks and need frequent attention.

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.
