How we handle grease filter exchange in Barnehurst

A filter service works alongside TR19® cleaning, not instead of it. Clean filters reduce the grease reaching the ducts, but some grease still passes through as vapour. That is why the whole system still needs cleaning to TR19 at the right interval. If you have a canopy running with filters missing and grease dripping from the canopy, we can help.

London kitchens tend to trade late and open early, so work in Barnehurst is normally booked for the night or the early hours. Parking, loading and access to the roof are agreed with the building before the night of the clean.

Good records are part of the job. You get a written report with pictures after every visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Grease, kitchens and Barnehurst

There are about 128 restaurants, cafés and canteens and about 82 sandwich bars and takeaways in and around Barnehurst, up to about a mile and a half out, according to the Food Standards Agency’s register. Each canopy among them has filters that load with grease and need swapping or cleaning. It’s Bexley council that sends environmental health officers to food businesses in Barnehurst. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Our report lists what was cleaned and when, which is useful to have ready. Night work suits London kitchens, and roads and loading bays tend to be quieter too.

Volunteers running a hall kitchen near Church of St Paulinus, or anywhere in Barnehurst, may not know when the extract was last cleaned, and a grease test settles it. Healthcare kitchens, like those at hospitals such as Erith and District Hospital (about 1.1 miles north), often cook for long hours, which puts them in BESA’s heavier-use bands.

Common problems we fix in Barnehurst

However long the kitchen cooks each day, the filters see every minute of it. Heavy daily use means fast build-up, so it needs more frequent changes.

The symptoms we are asked about most are:

  • A canopy running with filters missing
  • Filters that come out of the sink still dirty
  • Filters that leave gaps in the canopy
  • A canopy that drips grease

If you run a café or takeaway near Barnehurst station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits.

Before booking anyone

  • Whether the whole system is included, or only the parts that are easy to reach
  • Whether a survey comes first
  • Whether inaccessible sections are listed on the report
  • What hours they’ll be on site

How to choose an extract cleaning contractor

Questions from Barnehurst

Can you clean school kitchen extracts in Barnehurst during the holidays?

Yes. The holidays are the usual time for school work. Food Standards Agency records list about 28 schools, colleges and universities with registered kitchens within about a mile and a half of Barnehurst. Send us your term dates when you give us a ring on 0345 646 2711 or send us an email, and we’ll fit the work in.

Who inspects food businesses in Barnehurst?

Kitchens in Barnehurst are inspected by Bexley council’s environmental health officers. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.

Are you accredited?

Our accreditations are CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.

What paperwork should we keep on file?

Each report and certificate we give you, filed in the maintenance log with your in-house cleaning records. BESA says certificates should show the date, location and technician.

Will we have to stop cooking for a filter change?

Visits are short, and can be booked outside service times. There’s no wait between removing and refitting.

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.

Can you give a price for filter changes?

Filters, canopies and how often you need visits all affect the price. Send us details or photos and we will quote quickly.

Can one contract cover all our sites?

Yes. Send the list of sites and the work at each and you will get one fixed quote.

Why it’s worth doing now in Barnehurst

Washing filters in-house is an option for kitchens in Barnehurst, and it works when it’s done well and never skipped. When it does not happen reliably, an exchange makes it automatic. Shared walls, risers and roofs mean a problem at one London site seldom stays put.

A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. The price is fixed before we start.

Why book with us

  • We’re fully insured
  • In business since 2009
  • One contact for all your sites in London and the South East
  • We diagnose before we treat

Part by part

Baffle filters

In a baffle filter, the air zigzags through metal baffles. Grease drops out as it does.

Busy restaurant and pub kitchens

Kitchens that fry and grill all day load their filters fast. Their exchange schedule is typically the tightest.

What affects the cost of grease filter exchange

You’ll get a fixed price before any work starts. It takes into account:

  • How many systems or sites are involved
  • Access, including roofs, risers and ceiling voids
  • Site requirements such as sign-in and permits
  • Where the site is and how we reach it

Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at, and you’ll get one fixed quote.

Asking for a quote

A few details help us quote accurately. When you get in touch, it helps to send:

  • When the site is open and when it’s quiet
  • The paperwork from the last visit, if you have it
  • The site address and the type of premises
  • Any access panels or hatches you can see

Quoting starts with a diagnosis, either from photos and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before any work starts.

What staff can safely do

When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We’ll take a look and send you a fixed quote.

In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.

The process

There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. Getting kit into a London building takes planning, so let us know where we can load and park in Barnehurst.

  1. We record the number, size and type of your filters.
  2. We set the interval with you.
  3. The dirty set is lifted out.
  4. A clean set is fitted and checked for gaps.
  5. The dirty filters leave with us and the next visit is booked.

Preparing for the visit

  • Mention any sign-in, permit or induction we need
  • Plan for cooking equipment or plant to be off before we arrive
  • Move anything stored near the system

Ask for a quote

Here’s what helps us quote: where the site is, what it is and its opening hours, photos of the system and the last certificate or report, if there is one. Then call us on 0345 646 2711 or send us an email.
