Grease filter exchange for sites in Upper Walthamstow

Grease filter exchange in Upper Walthamstow, done properly

Across Upper Walthamstow, our filter exchange suits restaurants, pubs, cafés, schools, care homes and other kitchens, from a single canopy to several. Visits can be timed around your service so nobody has to stop cooking. The work covers wall canopies, baffle filters and school and hospital kitchens, and common reasons people get in touch are filters left unwashed on busy weeks and hand-washed filters that still look greasy.

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 Upper Walthamstow, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.

Nothing is signed off by word of mouth: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Why deal with it now?

Dripping canopies and greasy smells often start with the filters. Left, it ends up on equipment, food areas and staff and that is the kind of thing inspectors look for. London sites work long hours, and the longer a job is left, the bigger it gets.

A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. You will have a fixed price before we start.

Signs you need grease filter exchange in Upper Walthamstow

Hand-washed filters often come back still greasy. Grease lodges deep in baffles and mesh and a sink wash rarely reaches it.

Keep an eye out for any of the following:

  • Staff short of time to wash filters
  • Grease dripping from the canopy
  • Smoke and heat lingering under the hood
  • Bent or damaged filters that do not sit properly

If you run catering at a healthcare site, such as a hospital like Wanstead Hospital about 1.1 miles east, the extract may need cleaning more often than a part-time kitchen.

What your quote should include

  • Whether the work can be done while the site is closed
  • Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
  • Whether a written report and pictures are included
  • Whether they’re fully insured

Questions to ask before booking

How we price grease filter exchange

Your quote is based on your site. We consider:

  • How easy every part is to reach
  • Travel, parking and unloading
  • One-off work versus a regular cycle
  • How big the system is

Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered, and you will get one fixed quote.

Helping us quote

The more you tell us, the more accurate the quote. With your enquiry, please include:

  • Any access panels or hatches you can see
  • Any symptoms, from odd noises to smells or leaks
  • Photos showing the whole system and its surroundings
  • Your last certificate, test record or report

Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before any work starts.

In-house cleaning or a specialist?

Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.

Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.

How the visit works

There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with pictures. Most of the time goes on the work itself, which takes a few minutes per canopy, longer for a large kitchen with several canopies. In a London area like Upper Walthamstow, parking, loading and building access are planned before the day of the work.

  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.

How to prepare

  • Agree a time when the area can be out of use
  • Tell us about site rules, permits or sign-in
  • Arrange a key holder or contact on site

Getting a quote

To help us quote: where the site is, what it is and its opening hours, a few photos and the last certificate or report, if there is one. Then ring 0345 646 2711, or send details by email.

Part by part

Mesh filters

Layers of mesh catch grease droplets. They clog quickly in a busy kitchen, so they need changing often.

The plenum

A greasy plenum is a sign filters have been left too long or that the next TR19 clean is due.

For landlords and multi-site operators

Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.

Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.

Upper Walthamstow kitchens: local notes

The FSA’s food hygiene register includes about 46 pubs, bars and clubs and about 3 hotels, B&Bs and guest houses across Upper Walthamstow and its immediate surroundings (about a mile and a half). Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Overnight is the normal time to clean a London kitchen extract, so trading isn’t affected. Upper Walthamstow sits within the area of 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 run a café or takeaway near Wood Street station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits. If you run a church or community hall kitchen, near Church of St Peter in the Forest or elsewhere in Upper Walthamstow, its extract still collects grease from every lunch and event.

Upper Walthamstow is about 1 mile east of Walthamstow, in Greater London.

Upper Walthamstow questions

Who is the fire and rescue service for Upper Walthamstow?

London Fire Brigade is the fire and rescue service for Upper Walthamstow. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.

Who carries out food hygiene inspections in Upper Walthamstow?

The local authority for Upper Walthamstow is Waltham Forest council, and its environmental health team does the inspecting. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.

What does grease filter exchange cost?

The cost depends on your filters and the schedule. Just give us a ring on 0345 646 2711 or send us an email for a fixed quote once we know your canopies.

Is Upper Walthamstow in your area?

Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, and that includes Upper Walthamstow.

Does a filter exchange disrupt service?

Most changes take anything from a few minutes to an hour or so, depending on the number of filters, so the impact is small. We plan visits outside your busiest times wherever we can.

Where do the greasy filters go?

We do. The dirty filters are taken away for cleaning and the clean set stays in the canopy.

Which grease filters does the service cover?

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

How long does the visit take?

It depends on the size of the system, but for a typical site it takes a short visit, depending on how many filters the canopies hold. We’ll confirm it with the quote.
