Grease filter exchange in Knox Bridge

How we handle grease filter exchange in Knox Bridge

Grease filters are the first line of defence in a kitchen extract. Their job is to stop grease getting further into the system, but only while they’re reasonably clean. Our grease filter exchange service swaps dirty filters for clean ones on a schedule. The work covers mesh filters, island canopies and wall canopies, and the jobs we see most are staff short of time to wash filters and grease building up behind the canopy filters.

For a kitchen in or near Knox Bridge, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.

A written report with pictures follows every visit, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

What affects the cost of grease filter exchange

A fixed price needs a few facts first. We look at:

  • The condition of the system
  • A single visit or a regular plan
  • How many systems or sites are involved
  • Parking and loading at the site

Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we’ll go through it with you.

What to send for a quote

Photos let us diagnose from a distance. The most useful are:

  • Where the site is and what kind of site it is
  • The paperwork from the last visit, if you have it
  • A few general shots of the system
  • Your opening hours and when the area is out of use

Here’s what helps us quote: the address, the type of site and when it’s open, pictures of the system and the last certificate or report, if there is one. Then ring 0345 646 2711 or email us.

Looking after it afterwards

How long the results last depends on use and care. Here’s what we suggest:

  • Clean the canopy surfaces regularly
  • Never leave gaps in the filter bank
  • Keep the extract on whenever the range is in use
  • Make sure we can reach the canopy on exchange day

Fresh filters improve airflow at the canopy right away. Keep the extract running while you cook so they catch grease as intended.

Clean filters plus regular full cleans keep the system in good health. Setting both up on a schedule means neither slips.

When something else is needed

In fairness, there are a few things this work will not fix:

  • A canopy that does not capture the vapour properly
  • Extraction problems caused by the fan rather than the filters
  • Grease already built up in the ductwork, which needs a full TR19 clean

If you are not sure, just ring 0345 646 2711, or email photos and we will give you a straight answer.

Where we work

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

When to call us in Knox Bridge

Filters get bent and damaged with handling. Damaged filters don’t sit flush and grease passes round them.

Look out for these warning signs:

  • Bent or damaged filters that don’t sit properly
  • Staff short of time to wash filters
  • Grease collecting in the filter channels
  • Hand-washed filters that still look greasy

A hospital like Benenden Hospital, about 4.4 miles south-east, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

Questions to ask before booking

  • Whether the quote shows VAT
  • What paperwork you get at the end
  • Whether the whole system is included, or only the parts that are easy to reach
  • If the quote is a fixed price or an estimate

Questions to ask before you book

Knox Bridge: your questions answered

Who would carry out a food hygiene inspection at a kitchen in Knox Bridge?

In Knox Bridge, it’s Tunbridge Wells council that carries out food hygiene inspections. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.

Which fire authority looks after Knox Bridge?

That’s Kent Fire and Rescue Service. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.

How do you keep the site clean during the work?

With sheeting and covers, before anything else happens. We keep the work contained and clean down when we finish.

What types of premises do you cover?

Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.

Can you clean our existing filters instead?

Yes, that’s an option. The first step is looking at the filters you have because bent or damaged ones may need replacing.

Which records should we keep?

Anything that proves the system is maintained: reports, certificates, pictures and your own cleaning or check logs. A single log for each site works best.

Do you offer maintenance contracts?

Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.

Is Knox Bridge in your area?

Yes. Our technicians work in Knox Bridge, as part of our area across London and the South East.

Landlords, agents and facilities managers

From a single site to a large estate, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with pictures.

Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.

How it works

We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool first, and floors and nearby surfaces are sheeted. The work itself takes well under an hour for most canopies. The timing of a visit to Knox Bridge is set by you, and the travel is our side of the planning.

  1. The filters in each canopy are measured and counted.
  2. We set the interval with you.
  3. The dirty set is lifted out.
  4. Clean filters go in and we check they sit snugly.
  5. The dirty filters leave with us and the next visit is booked.

Getting ready for the visit

  • Arrange a key holder or contact on site
  • Mention any locked doors, roof access or ceiling voids
  • Find the previous report, if there is one

Getting a quote

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.

Why deal with it now?

A filter exchange is a few minutes; a choked extract affects a whole service. It’s one of the simplest parts of looking after the system, and one of the easiest to let slip. Out of sight is the usual reason a rural system goes too long without attention.

Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered, and you will get one fixed quote.

Why book with us

  • CHAS, SafeContractor and ISO 9001
  • In business since 2009
  • A single point of contact for sites across the South East and London
  • Fixed quotes from a survey or pictures
