Keeping the system healthy

Results last longer with the right care. We suggest:

  • Tell us if the menu or opening hours change
  • Keep filter exchange and TR19 cleaning on the same plan
  • Keep the extract on whenever the range is in use
  • Never leave gaps in the filter bank

The canopy looks cleaner and the air moves better from the moment they’re fitted. Always run the extract during cooking so the filters do their job.

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.

How we handle grease filter exchange in North Cray

An exchange visit in North Cray doesn’t take long. We lift out the dirty filters and fit a clean set, and we check they’re seated with no gaps. Anything that needs attention is pointed out. Common call-outs are for a greasy plenum behind the filters and grease left in baffles after washing, across school and hospital kitchens, restaurants and pubs and baffle filters.

Across London, many commercial kitchens are squeezed into basements and narrow back-of-house spaces, with extract ducts that can climb several floors to discharge at roof level. For a kitchen in North Cray, that usually means a longer system to clean and more access panels to plan around.

The sign-off is always in writing: a written report, dated and illustrated with photos, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

For landlords and multi-site operators

Records are where multi-site compliance often slips. Every visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.

We also work for facilities teams across offices, schools and healthcare in North Cray and across Greater London. Work can be phased by floor, building or site to keep disruption down.

Part by part

The plenum

Clean filters reduce the grease reaching the plenum, but it’s still cleaned during a full TR19 clean.

School, care home and staff kitchens

Even kitchens with fixed meal times build up grease, though often more slowly.

When to call us in North Cray

Repeated removal and washing takes its toll on filters. A bent filter does not seat properly, leaving gaps for grease to slip through.

Most sites get in touch when they notice something like this:

  • A greasy plenum behind the filters
  • Smoke and heat lingering under the hood
  • Filters that come out of the sink still dirty
  • Bent or damaged filters that don’t sit properly

Church and community hall kitchens, near Parish Church of St James or anywhere around North Cray, are easy to forget, but their extracts collect grease like any other.

Choosing a duct cleaning contractor

What staff can safely do

A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.

Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.

North Cray: your questions answered

Can parking be tricky for a job in North Cray?

Tell us where a van can stop near your site in North Cray, and about any building rules on loading. Where restrictions apply in the day, an evening or overnight visit usually gets round them.

Do you work overnight in North Cray?

Yes, evening, overnight and weekend work is normal for us. It means the site in North Cray keeps running as normal. Your opening times are the first thing we ask for.

How long does the visit take?

On site, it takes less than an hour in most kitchens. Larger systems naturally take longer, and the quote will say how long.

Which records should we keep?

Visit reports, certificates and your in-house cleaning logs. They’re what an insurer, fire officer or EHO may ask for, so keep them together and easy to find.

Do you work with multi-site operators?

Yes. One number covers all your sites in our area, and visits can be set on a regular cycle.

Do I get a report after the visit?

Yes. Every visit ends with a written report and pictures, showing what was done, anything we couldn’t reach and when the next visit is due. Where the work is a TR19® Grease clean, there’s also a certificate issued through the BESCA Vent Hygiene Elite portal.

What happens if you cannot reach some of it?

The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, which we can install.

What does grease filter exchange cost?

Every kitchen is different, so we need to know the filters and interval first. You get a fixed price before the service starts.

What grease filter exchange looks like in North Cray

The FSA’s food hygiene register shows about 73 restaurants, cafés and works canteens and about 27 takeaways and sandwich shops within about 1.5 miles of central North Cray. Any of those kitchens with a canopy relies on its filters to catch grease before it reaches the duct. Most London extract cleaning happens at night, after the last service. In North Cray, food businesses are inspected by environmental health officers from Bexley council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Keeping each certificate and photo report on file helps show the extract is looked after.

If you run catering at a healthcare site, such as a hospital like Bexley Hospital about 1.8 miles north, the extract may need cleaning more often than a part-time kitchen. Term dates shape school work: for a school like Royal Park Primary Academy, an extract clean fits neatly into a half-term or summer break.

How it works

We are 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. On site, 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 North Cray needs from us.

  1. We start by noting how many filters you have and what type they are.
  2. Together we set how often the filters should be changed.
  3. At each visit, the greasy filters are lifted out.
  4. Clean, dry filters are fitted in their place, with no gaps left between them.
  5. Anything we notice, such as bent filters or a dirty plenum, is pointed out.

How to prepare

  • Arrange a key holder or contact on site
  • Clear the space around the work
  • Plan for cooking equipment or plant to be off before we arrive

What affects the cost of grease filter exchange

Sites vary more than people expect. The main factors:

  • Whether several sites go on one quote
  • Site rules, permits and inductions
  • The condition of the system
  • One-off work versus a regular cycle

Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we will explain each part.

Helping us quote

What to send for a quote:

  • Your opening hours and when the area is out of use
  • A few general shots of the system
  • Any symptoms, from odd noises to smells or leaks
  • The roof, plant room or outside wall the system runs to

There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, and then send you a fixed quote. To get going, give us a ring on 0345 646 2711 or send us an email.
