How we handle grease filter exchange in New Barnet

Washing filters in the kitchen sink is messy and easily missed on a busy week. With a filter exchange, we bring a clean set and take the dirty one away and the canopy is refilled straight away. We are often asked to deal with damaged filters letting grease past and staff short of time to wash filters, across school and hospital kitchens, restaurants and pubs and baffle filters.

London kitchens tend to trade late and open early, so work in New Barnet is normally booked for the night or the early hours. Before the clean, we agree loading, parking and roof access with whoever manages the building.

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.

FAQs for New Barnet

Which fire service covers New Barnet?

New Barnet is in the area of London Fire Brigade. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.

Is parking a problem for work in New Barnet?

Tell us where a van can stop near your site in New Barnet, and about any building rules on loading. Night visits tend to make loading easier on London streets.

What do you do with what you remove?

Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. We do not leave it behind.

Which records should we keep?

Anything that proves the system is maintained: our reports and pictures, any certificates and your in-house logs. One maintenance log per site keeps it simple.

Do you work in New Barnet?

Yes. We cover New Barnet and the rest of Greater London, as part of our work across South East England and London. To book, give us a ring on 0345 646 2711, or send details by email.

Which accreditations do you hold?

BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We are fully insured and have been trading since 2009.

Is there a cleaning option for the filters we have?

We offer filter cleaning as well as exchange. We will talk you through which suits your kitchen when we quote.

Do you look at the system first?

Yes, always. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.

When to call us in New Barnet

However long the kitchen cooks each day, the filters see every minute of it. A kitchen that cooks all day loads its filters quickly so changes need to come round sooner.

Clients usually contact us after spotting one of these:

  • Weak extraction at the canopy
  • Hand-washed filters that still look greasy
  • Grease collecting in the filter channels
  • A canopy that drips grease

A hall kitchen that only cooks for events, whether near Holy Trinity Lyonsdown or elsewhere in New Barnet, still needs its extract cleaned, just less often.

Comparing quotes

  • When they can work, and whether that is outside your opening hours
  • If the quote is a fixed price or an estimate
  • What happens if part of the system cannot be accessed
  • How VAT is shown on the quote

How to choose an extract cleaning contractor

What grease filter exchange cannot fix

We will not sell you work that does not address the problem, so these are the things it will not cover:

  • Cooking smells reaching neighbours, which need odour control
  • Grease already built up in the ductwork, which needs a full TR19 clean
  • A canopy too small for the cooking beneath it

If in doubt, give us a ring on 0345 646 2711, or send details by email and we will say what we think before you book.

What the work covers

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

The process

The first job on site is protection: floors, worktops and anything near the work are covered. Then we make the system safe and start. It takes well under an hour for most canopies, and we clear up before we go. Before any visit in New Barnet, we agree where the van can stop and how equipment reaches the system.

  1. We count and measure the filters in every canopy.
  2. A change schedule is agreed to match the kitchen’s cooking hours.
  3. At each visit, the greasy filters are lifted out.
  4. We fit clean filters and check they sit snugly in the housing.
  5. We flag any damaged filters or anything wrong with the canopy.

Preparing for the visit

  • Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
  • Tell us the best time to work, such as after service or at a weekend
  • Mention any parking or loading restrictions

Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

What your team can do, and what needs us

Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.

Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.

For landlords and multi-site operators

When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side and send the paperwork to whoever needs it.

For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.

How we price grease filter exchange

Every site gets its own quote. This is what makes a difference:

  • The times the site is available
  • Any permits to work or inductions
  • The number of sites or systems
  • Access, including roofs, risers and ceiling voids

What you pay depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before any work starts, so you know where you stand.

Asking for a quote

When you contact us, it’s useful to have:

  • The site address and the type of premises
  • The roof, plant room or outside wall the system runs to
  • A few general shots of the system
  • Anything you’ve noticed, such as smells, noise, drips or poor airflow

To get a fixed quote, phone us on 0345 646 2711 or use the quote form and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. We normally come back within one working day.

Grease filter exchange in New Barnet: the local picture

The Food Standards Agency lists about 32 pubs and bars as registered food businesses within 1.5 miles or so of the middle of New Barnet. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Environmental health officers from Barnet council inspect food businesses in New Barnet. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Before-and-after photos from each clean are a simple way to show the extract is in hand. London jobs typically start after the last service, with loading and roof access agreed with the building first.

A kitchen near New Barnet station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval. Bursars and site managers at schools such as St Mary's CofE Primary School tend to book extract cleaning for when the kitchen is empty.

What the work involves, part by part

School, care home and staff kitchens

Even kitchens with fixed meal times build up grease though normally at a gentler pace.

Canopy filter housings

Filters sit in a housing or channel in the canopy. A damaged housing leaves gaps.
