Grease filter exchange for sites in Sudbury Hill

Grease filter exchange in Sudbury Hill

Good filters only work when they fit properly. Gaps in the filter bank are a direct route into the plenum, so we check every one at each visit. We point out any that need replacing. Common call-outs are for grease filters clogged with grease and missing filters in the filter bank, on island canopies, mesh filters and restaurants and pubs.

Across London, many commercial kitchens are squeezed into basements and narrow back-of-house spaces, and the duct may run up through several floors before it discharges at the roof. In Sudbury Hill, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.

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.

What a clean won’t put right

An honest diagnosis matters more to us than a booking, so here’s what grease filter exchange won’t do:

  • Greasy ducts and risers that a filter change will not reach
  • Smell complaints that need odour control equipment
  • An extract that was undersized from the start

If you are not sure, just phone us on 0345 646 2711 or send us an email and we will give you a straight answer before booking.

What we work on in Sudbury Hill

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

How the job changes from site to site

Mesh filters

Layers of mesh catch grease droplets. They clog quickly in a busy kitchen and need frequent attention.

Baffle filters

In a baffle filter, the air zigzags through metal baffles. Grease is thrown out of the airstream and collects on the baffles.

For landlords and multi-site operators

Facilities teams in offices, schools and healthcare sites book us too in Sudbury Hill and across Greater London. Larger estates can be phased building by building to keep disruption down.

The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.

The process

We’re used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. The visit itself takes a short visit, depending on how many filters the canopies hold. In Sudbury Hill, as across London, we usually work overnight or at weekends and hand the site back ready to open.

  1. We look at the canopies and the condition of the filters.
  2. Any damaged or missing filters are noted.
  3. We exchange the dirty filters for a clean set.
  4. We check the filters are seated and the canopy is ready to use.
  5. Anything that needs attention, such as a greasy plenum, is pointed out.

Preparing for the visit

  • Clear the space around the work
  • Make sure equipment near the work can be switched off and left to cool
  • Let us know when the site is closed or quiet

Ask for a quote

Here’s what helps us quote: the address, the type of site and when it’s open, photos of the system and the last certificate or report, if there is one. Then call 0345 646 2711 or drop us a line.

Aftercare tips

How long the results last depends on use and care. We suggest:

  • Keep every filter in place during service
  • Keep canopy surfaces wiped down
  • Book full TR19 cleans alongside filter changes
  • Do not refit a filter that’s bent

Fresh filters improve airflow at the canopy from the moment they’re fitted. Always run the extract during cooking so they catch grease as intended.

Filters that are left too long stop protecting the system. A regular cycle keeps the rest of the system cleaner until the next TR19 clean.

Leave it or put it right?

Washing filters in-house is an option for kitchens in Sudbury Hill, and it works when it’s done well and never skipped. Where it slips, an exchange service takes the job off staff. London buildings are shared, so a fire or failure in one system can reach the neighbours above and beside you.

When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account, and the price is fixed before work begins.

Why Sudbury Hill businesses choose us

  • A written report with photos after every visit
  • CHAS, SafeContractor and ISO 9001
  • Out-of-hours work and a 24/7 emergency line

What grease filter exchange looks like in Sudbury Hill

Look up Sudbury Hill on the FSA’s food hygiene register and you will find about 157 restaurants, cafés and canteens and about 130 takeaways and sandwich shops in and around Sudbury Hill, up to about a mile and a half out. Where they cook under a canopy, the grease filters are the first line of defence and clog quickly. Fire safety in Sudbury Hill falls to London Fire Brigade. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. It’s Brent council that sends environmental health officers to food businesses in Sudbury Hill. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Keeping each certificate and photo report on file helps show the extract is looked after.

A hospital like Clementine Churchill Hospital, about 1 mile north-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day. If you run a café or takeaway near Sudbury & Harrow Road station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits. For schools such as Sudbury Primary School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.

Questions from Sudbury Hill

Is parking a problem for work in Sudbury Hill?

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

Which fire authority looks after Sudbury Hill?

Fire safety enforcement in Sudbury Hill is handled by London Fire Brigade. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.

What accreditations do you have?

We hold CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.

How regularly do grease filters need exchanging?

It depends on how much and what the kitchen cooks. Heavy cooking means more frequent changes than kitchens that cook less. We agree the interval with you.

Where does the waste go?

Waste is contained during the work and removed when we leave, including grease, debris and dirty water. We do not leave it behind.

Will we have to stop cooking for a filter change?

Most changes take a short visit, depending on how many filters the canopies hold, so the impact is small. We will fit it around your service wherever possible.

What does TR19 mean?

TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.

Do you handle baffle and mesh filters?

We exchange baffle and mesh filters. At the start, we note what your canopies use so the clean set always fits.

In-house cleaning or a specialist?

Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.

If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We can diagnose it and quote.
