Grease filter exchange near Angel

What the work involves, part by part

School, care home and staff kitchens

For kitchens closed in the holidays, visits can be timed around term or rota, keeping the filters ready for the busy weeks.

The plenum

Behind the filters sits the plenum, where air gathers before the duct. Grease that gets past the filters settles there.

About our grease filter exchange in Angel

Think of filter exchange as routine care for the extract. Between full cleans, it keeps the airflow healthy and takes a messy task off your team. Full TR19 cleaning still comes at the right interval, with a certificate. If you have filters so greasy the air can barely pass and weak extraction at the canopy, we can put it right, from school and hospital kitchens, baffle filters and restaurants and pubs onwards.

In London, few kitchens can spare a day to close, so extract cleaning in Angel is normally done overnight, after the last service. Parking, loading and access to the roof are agreed with the building before the night of the clean.

Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

Multi-site and managed buildings

Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we will send a fixed quote.

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.

Signs you need grease filter exchange in Angel

Kitchens in Angel, as everywhere, find filter washing slips down the list on busy weeks. A missed wash or two is all it takes for filters to fill with grease.

Any of these means the system needs a check-up:

  • Filters that leave gaps in the canopy
  • Grease left in baffles after washing
  • Filters so greasy the air can barely pass
  • Grease building up behind the canopy filters

Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Finsbury Health Centre is the nearest hospital to Angel, about 0.5 miles south.

Questions to ask before booking

  • Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
  • Whether the quote is based on a survey or pictures
  • How areas they can’t reach will be recorded
  • What records you’ll receive afterwards

Your questions about grease filter exchange in Angel

Can parking be tricky for a job in Angel?

We plan it in advance, so let us know about loading bays, permits and access rules at the building. Night visits tend to make loading easier on London streets.

Who is the fire and rescue service for Angel?

London Fire Brigade is the fire and rescue service for Angel. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.

How long does the visit take?

It depends on the size of the system, but for a typical site it takes less than an hour in most kitchens. We’ll give you a better idea when we quote.

What’s TR19?

TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.

What does grease filter exchange cost?

The cost depends on your filters and the schedule. Just phone us on 0345 646 2711 or send us an email for a fixed quote, usually within one working day.

Do you clean filters as well as exchanging them?

We can. Cleaning your existing filters is an option, and others prefer a straight swap. We make sure the canopy is ready for service either way.

Do you survey before quoting?

Yes. For many sites, pictures and a few details are enough, and larger or hidden systems get a visit.

Which accreditations do you hold?

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

Fixed quotes for grease filter exchange in Angel

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

  • The scale of the work
  • Access, including roofs, risers and ceiling voids
  • Whether several sites go on one quote
  • Parking and loading at the site

What you pay reflects the actual work. That is why every job is surveyed first, and why the quote is fixed before any work starts.

What to send for a quote

To speed up the quote, send us:

  • When the site is open and when it’s quiet
  • Photos showing the whole system and its surroundings
  • Detail shots of panels, filters and grilles
  • The roof, plant room or outside wall the system runs to

Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.

Keeping the system healthy

A little care between visits keeps the system in better shape. We recommend:

  • Do not let the full clean slip because filters are changed
  • Clear anything stored on or near the canopy
  • Keep canopy surfaces wiped down
  • Watch for grease drips between visits

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

Clean filters plus regular full cleans keep the system in good health. A maintenance plan that covers both keeps everything on track.

What we do, step by step

Every visit runs to the same pattern: sheeting and protection first, make the system safe, carry out the grease filter exchange, tidy up and hand over the paperwork. On site, the work takes less than an hour in most kitchens. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Angel.

  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. We tell you if the plenum or canopy needs a clean.

Getting ready for the visit

  • Have your last certificate or report to hand
  • Clear the space around the work
  • Tell us the best time to work, such as after service or at a weekend

Ask for a quote

Getting a quote does not take long. Send a few details and photos, and we normally reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

Advice

Honest limits

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

  • A canopy that doesn’t capture the vapour properly
  • Cooking smells reaching neighbours, which need odour control
  • Grease already built up in the ductwork, which needs a full TR19 clean

If in doubt, call 0345 646 2711, or send details by email and we will say what we think.

Parts of the system we cover

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