Grease filter exchange in Coldharbour: the local picture

The FSA’s food hygiene register shows about 6 restaurants, cafés and works canteens and about 3 sandwich bars and takeaways across Coldharbour and its immediate surroundings (about a mile and a half). Swapping filters on a schedule keeps kitchens like these drawing air properly. In Coldharbour, food businesses are inspected by environmental health officers from Tonbridge and Malling council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Before-and-after photos from each clean are a simple way to show the extract is in hand. Kent Fire and Rescue Service covers Coldharbour. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.

Historic houses near Coldharbour, such as Ightham Mote about 2.2 miles north, are a reminder that older buildings with event kitchens can have long, awkward duct routes. If you look after a school kitchen, at a school such as St Margaret Clitherow Catholic Primary School or anywhere near Coldharbour, the holidays are the usual time for a TR19® clean. Where a hall near Parish Church of St John, or anywhere in Coldharbour, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

Grease filter exchange in Coldharbour

Filter exchange sits between full TR19® cleans. Clean filters reduce the grease reaching the ducts, but some grease still passes through as vapour. So the canopy, plenum and ducts still need their full TR19 clean. If you have weak extraction at the canopy and grease building up behind the canopy filters, we can put it right, from mesh filters, restaurants and pubs and island canopies onwards.

Work in a small place like Coldharbour starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.

We are CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

What grease filter exchange cannot fix

Grease filter exchange cannot fix everything, and we will tell you before any work starts. It won’t put right:

  • A canopy too small for the cooking beneath it
  • Grease already built up in the ductwork, which needs a full TR19 clean
  • Extraction problems caused by the fan rather than the filters

If you’re not sure, just call us on 0345 646 2711, or send details by email and we will give you a straight answer before you book.

What the work covers

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

Aftercare tips

After the visit, a few habits help the work last:

  • Keep the canopy clear for exchange visits
  • Book full TR19 cleans alongside filter changes
  • Keep the extract on whenever the range is in use
  • Make sure no filter is left out

Your next visit is scheduled before we leave. If cooking increases, we can change filters more often to match.

If cooking has stepped up, the filter schedule should too. Changing the interval early stops grease building up unseen behind the canopy.

How the job changes from site to site

Canopy filter housings

We check that filters sit snugly in the housing at each visit, because gaps let grease through.

Mesh filters

Layers of mesh catch grease droplets. In a busy kitchen, mesh soon blocks and need frequent attention.

Landlords, agents and facilities managers

We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.

If you look after several sites, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.

Fixed quotes for grease filter exchange in Coldharbour

We quote each job individually. This is what makes a difference:

  • Access, including roofs, risers and ceiling voids
  • A single visit or a regular plan
  • How many systems or sites are involved
  • Any permits to work or inductions

A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. You’ll have a fixed price before work begins.

What to send for a quote

Before you ask for a quote, gather:

  • Any access panels or hatches you can see
  • Wide pictures of the system and the area around it
  • How we’d reach plant on a roof or in a plant room
  • The times we could work without disrupting the site

Quoting starts with a diagnosis, from your pictures and details or, where that is not enough, a survey on site. 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, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We’ll take a look and send you a fixed quote.

Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.

FAQs for Coldharbour

Can you come to Coldharbour after we close?

Yes, we can come after you close and finish before you open. The site is handed back ready to open. Just call us on 0345 646 2711, or email photos with your opening times and we’ll plan around them.

Who inspects food businesses in Coldharbour?

Food hygiene inspections in Coldharbour are carried out by Tonbridge and Malling council. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.

What types of premises do you cover?

Any commercial site with kitchens or ventilation, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.

Do you work in Coldharbour?

Yes. Our technicians work in Coldharbour, within the South East and London area we cover.

What do you do with what you remove?

We take it away when we go. During the work, it’s contained so the area stays clean.

What paperwork should we keep on file?

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

What if parts of the system cannot be reached?

They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, along with a quote to put access in.

How long does the visit take?

We’ll confirm the time with your quote. For a typical site, it takes well under an hour for most canopies.

The process

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. The visit itself takes anything from a few minutes to an hour or so, depending on the number of filters. A few pictures of the system help us make the most of a visit to a place like Coldharbour.

  1. The filters in each canopy are measured and counted.
  2. An exchange schedule is agreed to suit your cooking.
  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

  • Tell us about site rules, permits or sign-in
  • Allow time for equipment near the work to be turned off and cool down
  • Have your last certificate or report to hand

Get a fixed quote

Getting a quote does not take long. Call or email with a few details and you will usually have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
