Grease filter exchange for sites in East Barnet

How we handle grease filter exchange in East Barnet

The filters in the canopy are the first thing cooking vapour meets. Their job is to stop grease getting further into the system and they do it best when they’re clean. Our grease filter exchange service swaps dirty filters for clean ones on a schedule. If you’re dealing with blocked baffle filters and damaged filters letting grease past, we can help, from mesh filters, baffle filters and school and hospital kitchens onwards.

In London, few kitchens can spare a day to close, so extract cleaning in East Barnet is usually done overnight, after the last service. Before the clean, we agree loading, parking and roof access with whoever manages the building.

Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Kitchen extracts in East Barnet

The Food Standards Agency lists about 41 pubs and bars as registered food businesses within 1.5 miles or so of the middle of East Barnet. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Kitchens in East Barnet get their food hygiene inspections from Barnet council. Extraction counts as kitchen equipment, so its condition can come up on the day. Before-and-after photos from each clean are a simple way to show the extract is in hand. The fire and rescue service for East Barnet is 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.

If you look after a school kitchen, at a school such as Church Hill School or anywhere near East Barnet, the holidays are the usual time for a TR19® clean. Healthcare kitchens, like those at hospitals such as Finchley Memorial Hospital (about 2.2 miles south-west), often cook for long hours, which puts them in BESA’s heavier-use bands.

Common questions in East Barnet

Do you clean school canteen extracts around East Barnet out of term?

Yes, out-of-term visits are normal for schools. With about 51 schools and colleges on the FSA’s register within roughly a mile and a half of East Barnet, it pays to plan holiday dates ahead. Send us your term dates when you give us a ring on 0345 646 2711 or email us, and we will fit the work in.

Do you work overnight in East Barnet?

Yes, evening, overnight and weekend work is normal for us. That way a site in East Barnet does not have to lose a day’s trading. Tell us your opening hours when you ask for a quote.

Who is responsible for fire safety on the premises?

It depends on the building. The Fire Safety Order 2005 puts the duty on the responsible person, which can be the employer, the owner, a landlord, an FM or a managing agent.

How long does the visit take?

It depends on the size of the system, but for many sites it takes well under an hour for most canopies. We’ll give you a better idea when we quote.

What types of premises do you cover?

Any site with a kitchen or a ventilation system to look after, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.

Can we book visits on a schedule?

Yes. We run scheduled maintenance contracts, set at the interval the system needs. Each report recommends when the next visit should be.

Is there a cleaning option for the filters we have?

Yes. Some kitchens prefer their own filters cleaned on a schedule while others want an exchange. Either way, the canopy is not left without filters during service.

What types of filter do you exchange?

We work with both baffle and mesh filters. The first step is recording what you have and set up the service around them.

What we do, step by step

There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Afterwards, the area is left tidy and the written report follows. For a job in East Barnet, tell us about loading bays, permits, lifts and roof access when you book.

  1. We look at the canopies and the condition of the filters.
  2. We note any filters that are bent, damaged or missing.
  3. Greasy filters are swapped for clean ones.
  4. The filters are checked for fit before we go.
  5. We tell you if the plenum or canopy needs a clean.

Preparing for the visit

  • Allow time for equipment near the work to be turned off and cool down
  • Clear the space around the work
  • Agree a time when the area can be out of use

How to get a quote

Getting a quote doesn’t take long. Send a few details and photos, and we normally reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.

Advice

Common problems we fix in East Barnet

Repeated removal and washing takes its toll on filters. A bent filter doesn’t seat properly and grease passes round them.

The symptoms we’re asked about most are:

  • Weak extraction at the canopy
  • Grease dripping from the canopy
  • Gaps where filters have been removed
  • Hand-washed filters that still look greasy

If you cook for passing trade around Oakleigh Park station, the extract can be cleaned between your last and first customer.

Before you book anyone

  • Whether the whole system is included, or only the parts that are easy to reach
  • When the next visit should be, and why
  • What records you’ll receive afterwards
  • Whether a survey comes first

Questions to ask before you book

How we price grease filter exchange

The quote reflects the site in front of us. We take into account:

  • The number of sites or systems
  • The condition we find in the survey
  • Site rules, permits and inductions
  • How big the system is

Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll explain each part.

Helping us quote

Many jobs can be priced from pictures and some basics. Send what you can of the following:

  • The site address and the type of premises
  • The times we could work without disrupting the site
  • How we’d reach plant on a roof or in a plant room
  • Problems your staff have spotted

The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.

Multi-site and managed buildings

Multi-site operators often want one contractor and one number. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.

Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We’re happy to deal with either side, and the report can go to both.

What the work involves, part by part

School, care home and staff kitchens

Kitchens that cook for set mealtimes still load their filters, though often more slowly.

Mesh filters

Mesh filters are still found in many canopies. They can be on the same exchange schedule as baffle filters.

Why deal with it now?

In East Barnet, as everywhere, a filter service is not a substitute for TR19 cleaning. But clean filters do help the system between cleans, and that shows when the next clean comes round. Planning ahead in East Barnet lets you pick a quiet night rather than lose a busy one.

No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.

Why book with us

  • Fixed quotes, usually within one working day
  • Survey first, then a fixed quote
  • CHAS, SafeContractor and ISO 9001
  • In business since 2009

Between visits

Looking after the system between visits is straightforward, and it makes the next visit easier:

  • Wipe the outside of the canopy as part of daily cleaning
  • Keep the canopy clear for exchange visits
  • Watch for grease drips between visits
  • Make sure no filter is left out

Your next visit is scheduled before we leave. If the kitchen gets busier, the interval can be shortened to keep up.

Dripping filters are a clear sign they’re full. Changing them now reduces the fuel above the cooking and the plenum may need a clean as well.
