Grease filter exchange for sites in Bishopsgate

How we handle grease filter exchange in Bishopsgate

Whether your canopy has baffle or mesh filters, they load up with grease. Once they’re clogged, airflow drops and the extract struggles. A steady cycle of clean filters keeps extraction strong. The work covers baffle filters, island canopies and mesh filters, and people most often call us about filter washing that keeps being missed and grease building up behind the canopy filters.

Work in a small place like Bishopsgate starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.

We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Bishopsgate: your questions answered

Who enforces fire safety at workplaces in Bishopsgate?

Surrey Fire and Rescue Service is the fire and rescue service for Bishopsgate. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.

Can school kitchens in Bishopsgate be cleaned in the holidays?

Yes, and it’s the easiest time to do it. The FSA’s register shows about 17 schools and colleges with food registrations within roughly a mile and a half of Bishopsgate. Send us your term dates when you phone us on 0345 646 2711 or use the quote form, and we will fit the work in.

Will you tell us when the next visit is due?

Yes. The recommended date is on the report. For kitchen extracts, BESA’s minimum intervals run from every 3 months for heavy use to every 12 months for light use, and fire dampers need testing at least once a year.

Which sectors do you work in?

Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.

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

No. Filter exchange works between full cleans, not instead of them. TR19® cleaning covers the canopy, plenum, ductwork and fan, with a certificate and photo report.

Are you insured?

Yes. We’re fully insured, and we can share the details when you need them.

Do you work in Bishopsgate?

Yes. We work in Bishopsgate and across Surrey, as part of our work across South East England and London. For a fixed quote, phone us on 0345 646 2711 or email us.

Do you have a 24/7 line?

Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we will advise on what to do next.

Signs you need grease filter exchange in Bishopsgate

Wherever you are, Bishopsgate included, filter washing is the job that gets skipped when the kitchen is busy. It only takes a couple of missed weeks for filters to fill with grease.

The symptoms we’re asked about most include:

  • Missing filters in the filter bank
  • Damaged filters letting grease past
  • Weak extraction at the canopy
  • Blocked baffle filters

If you run a church or community hall kitchen, near Royal Chapel of All Saints or elsewhere in Bishopsgate, its extract still collects grease from every lunch and event.

Before booking anyone

  • Which accreditations they hold, and whether you can check them
  • Whether they’re fully insured
  • Whether a survey comes first
  • When the next visit should be, and why

Questions to ask before booking

When something else is needed

Some problems need a different service or another trade:

  • A fan that’s failing or too weak for the system
  • A heavily greased plenum or canopy, which needs cleaning to TR19
  • An extract that was undersized from the start

If you’re not sure, just call 0345 646 2711 or drop us a line and we’ll give you a straight answer before booking.

Where we work

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

Managing agents and facilities teams in Bishopsgate

Keeping records across a portfolio is half the battle. Every visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.

Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.

How we price grease filter exchange

Every site gets its own quote. These are the things that affect it:

  • Access, including roofs, risers and ceiling voids
  • The size of the system
  • Site requirements such as sign-in and permits
  • Whether it’s a one-off visit or part of a schedule

The cost depends on the size of the system, what state it’s in and how easy it is to reach. We give you a fixed price before any work starts, so there are no surprises.

What to send for a quote

There’s no need for technical detail. It helps if you can send:

  • Close-ups of filters, grilles, hatches or access panels
  • Your last certificate, test record or report
  • The times we could work without disrupting the site
  • Where the plant sits or the system leaves the building, such as a roof or outside wall

Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

Looking after it afterwards

Once we’ve finished, these simple steps help:

  • Watch for grease drips between visits
  • Book full TR19 cleans alongside filter changes
  • Keep the canopy clear for exchange visits
  • Don’t refit a filter that’s bent

Your next visit is scheduled before we leave. If cooking increases, we can change filters more often to match.

Filters that are left too long stop protecting the system. Getting onto a regular exchange now keeps grease out of the plenum and ductwork between full cleans.

How the visit works

Night work is normal for us. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. The visit itself takes a few minutes per canopy, longer for a large kitchen with several canopies. For a village or hamlet like Bishopsgate, tell us about narrow lanes, gates and parking when you book.

  1. The filters in each canopy are measured and counted.
  2. We set the interval with you.
  3. On each visit, we remove the greasy filters.
  4. Clean filters go in and we check they sit snugly.
  5. The dirty filters leave with us and the next visit is booked.

Getting ready for the visit

  • Make sure someone can let us in and lock up afterwards
  • Clear loose items from the work area
  • Let us know about permits to work or site inductions

Getting a quote

We do not publish a price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To start, phone us on 0345 646 2711 or drop us a line.

Leave it or put it right?

In Bishopsgate, as everywhere, a filter service isn’t a substitute for TR19 cleaning. But clean filters do help the system between cleans, and that shows when the next clean comes round. If the system at a site near Bishopsgate fails, there may be nowhere nearby to move to.

We don’t list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll talk you through it.
