About our grease filter exchange in Chingford

Good filters only work when they fit properly. Bent, damaged or missing filters leave gaps, so we check every one at each visit. We point out any that need replacing. If you have grease collecting in the filter channels and gaps where filters have been removed, we can help.

London kitchens are often tucked into basements or the back of a building, with extract ducts that can climb several floors to discharge at roof level. In Chingford, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.

It’s worth checking any contractor’s accreditations. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Chingford: your questions answered

Do you work at weekends in Chingford?

Yes, we can come after you close and finish before you open. That way a site in Chingford does not have to lose a day’s trading. When you call us on 0345 646 2711 or send us an email, mention when the site is quiet.

Who is the fire and rescue service for Chingford?

Fire safety enforcement in Chingford is handled by London Fire Brigade. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.

What about areas you cannot get to?

We never leave them off the paperwork. You’ll know exactly which parts weren’t reached and why, and we can quote to improve the access.

Does the report say when we need you again?

Yes. We put a recommended next date on the report. BESA’s minimum intervals for kitchen extracts range from 3-monthly for heavy use to 12-monthly for light use, and fire dampers need testing at least once a year.

What if some of our filters are damaged?

A bent filter leaves a gap for grease. We point them out on the visit and explain what’s needed.

Do you work with multi-site operators?

Yes. One number covers all your sites across London and the South East, with visits on a regular schedule.

Which sectors do you work in?

Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.

Do we lose a day’s trading?

Not normally. The area we are working in has to be out of use while we are there, so the visit goes in a quiet slot.

What staff can safely do

A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That is our job.

For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.

How the job changes from site to site

School, care home and staff kitchens

For kitchens closed in the holidays, visits can be timed around term or rota so the filters are clean when cooking picks up.

The plenum

With good filters, less grease ends up in the plenum, but it’s still cleaned during a full TR19 clean.

When it’s something else

Before booking, it helps to know what’s not included:

  • Grease already built up in the ductwork, which needs a full TR19 clean
  • A canopy that needs a proper clean
  • Cooking smells reaching neighbours, which need odour control

If you’re not sure, just phone us on 0345 646 2711, or email photos and we’ll give you a straight answer before you book.

Parts of the system we cover

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

Grease filter exchange around Chingford

Look up Chingford on the FSA’s food hygiene register and you will find about 113 restaurants, cafés and canteens and about 47 takeaways in Chingford and the streets around it, up to about 1.5 miles out. Any of those kitchens with a canopy relies on its filters to catch grease before it reaches the duct. Kitchens in Chingford get their food hygiene inspections from Waltham Forest council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A dated certificate in the maintenance file answers the question before it’s asked. Chingford is covered by London Fire Brigade. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.

For schools such as Parkside Primary School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed. If you run a church or community hall kitchen, near All Saints' Church or elsewhere in Chingford, its extract still collects grease from every lunch and event.

What we do, step by step

When we arrive, we check the system against the survey or the photos you sent. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes anything from a few minutes to an hour or so, depending on the number of filters. Security desks and permits-to-work are routine in London, so let us know what your building in Chingford needs from us.

  1. First, we record the size, type and number of filters in each canopy.
  2. We agree a schedule that suits how much the kitchen cooks.
  3. Each visit starts with the used filters being removed.
  4. Clean, dry filters are fitted in their place, with no gaps left between them.
  5. If a filter is damaged or the plenum needs attention, we tell you.

Getting ready for the visit

  • Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
  • Find the previous report, if there is one
  • Let us know when the site is closed or quiet

Common problems we fix in Chingford

The type of cooking matters. Frying, grilling and chargrilling produce far more grease than steaming or baking so no single schedule suits every kitchen.

Most sites get in touch after spotting something like this:

  • Filters so greasy the air can barely pass
  • Staff short of time to wash filters
  • Grease dripping from the canopy
  • Damaged filters letting grease past

A hospital like Wanstead Hospital, about 3.1 miles south-east, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

Questions to ask before you book

  • How areas they cannot reach will be recorded
  • What insurance they carry
  • Whether a written report and photos are included
  • Proof of accreditation you can verify

Choosing a duct cleaning contractor

Leave it or put it right?

Leaving filters too long pushes more grease into the plenum and ducts. That makes the next full clean a bigger job, and grease may build up faster than the cleaning interval allows. A building in Chingford may have flats or offices above and alongside, and a fault in the system can affect them too.

The price reflects the work, not guesswork. That is why we survey first, from pictures or on site, and why the quote is fixed before any work starts.
