How we handle grease filter exchange in Cranbrook Common

In Cranbrook Common, our filter exchange runs on a schedule set by how much the kitchen cooks. The heavier the cooking, the more often filters need changing while a lighter kitchen can go longer. The interval is agreed before the first visit. If you have a canopy that drips grease and damaged filters letting grease past, we can put it right.

In a small place like Cranbrook Common, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. We agree access and timings in advance.

For insurers and inspectors, the record counts. That is why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What we are called out for in Cranbrook Common

Sometimes a filter is taken out and never put back. Every gap in the filter bank lets grease straight into the plenum and on into the ductwork.

What we’re most often called out for:

  • Grease left in baffles after washing
  • Grease collecting in the filter channels
  • Poor airflow through the filters
  • A canopy that drips grease

A hall kitchen that only cooks for events, whether near Church of the Holy Trinity or elsewhere in Cranbrook Common, still needs its extract cleaned, just less often.

What to look for in a quote

  • Whether a survey comes first
  • If the quote is a fixed price or an estimate
  • Whether inaccessible sections are listed on the report
  • Whether the quote shows VAT

Questions to ask before you book

How the job changes from site to site

Mesh filters

Mesh filters are still found in many canopies. We exchange them on the same basis as baffles.

School, care home and staff kitchens

Kitchens that cook for set mealtimes still load their filters, though often more slowly.

Keeping the system healthy

Think of this as the after-treatment advice, in brief:

  • Mention it if the kitchen gets busier
  • Never leave gaps in the filter bank
  • Make sure we can reach the canopy on exchange day
  • Book full TR19 cleans alongside filter changes

The next exchange is already in the diary. If cooking increases, we can change filters more often to keep up.

Saturated filters let more grease through. Getting onto a regular exchange now keeps grease out of the plenum and ductwork until the next TR19 clean.

In-house cleaning or a specialist?

Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.

In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.

Leave it or put it right?

Changing filters on schedule costs far less disruption than a blocked extract. It’s one of the simplest parts of looking after the system and few are as easy to forget. Our emergency line runs 24/7, but a planned visit to Cranbrook Common is calmer for everyone.

No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.

What affects the quote in Cranbrook Common

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

  • One-off work versus a regular cycle
  • Travel, parking and unloading
  • Working hours and out-of-hours timing
  • How many systems or sites are involved

What you pay depends on the size of the system, what state it’s in and how easy it is to reach. You get a fixed price before work begins, so there are no surprises.

What to send for a quote

You do not need the technical terms. It helps if you can send:

  • Wide photos of the system and the area around it
  • Where the plant sits or the system leaves the building, such as a roof or outside wall
  • Anything you’ve noticed, such as smells, noise, drips or poor airflow
  • Your opening hours and when the area is out of use

Quoting starts with a diagnosis, from your pictures and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work so you know the cost before we start.

What happens on the day

Protection comes first: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes less than an hour in most kitchens, and the area is cleaned down before we leave. Photos of the system and how to reach it help us plan a visit to Cranbrook Common.

  1. We count and measure the filters in every canopy.
  2. Together we set how often the filters should be changed.
  3. Each visit starts with the used filters being removed.
  4. Clean filters go straight back in, seated properly with no gaps.
  5. If a filter is damaged or the plenum needs attention, we tell you.

Before we arrive

  • Allow time for equipment near the work to be turned off and cool down
  • Clear loose items from the work area
  • Arrange a key holder or contact on site

Questions from Cranbrook Common

Is Cranbrook Common within the area you cover?

Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.

Can the work in Cranbrook Common be done at night or at weekends?

Yes, nights and weekends are routine for us. It means the site in Cranbrook Common keeps running as normal. Tell us your opening hours when you ask for a quote.

Which records should we keep?

Everything that shows the system is looked after: reports, certificates, pictures and your own cleaning or check logs. One maintenance log per site keeps it simple.

What does TR19 mean?

It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.

How do you protect the area?

With sheeting and covers, before anything else happens. We keep the work contained and leave the area clean.

Do I get a report after the visit?

Yes, on every job. The report is dated and includes pictures, and TR19® Grease cleans come with a certificate through the BESCA VHE portal. Keep it in your maintenance log.

Who is responsible for fire safety on the premises?

The Fire Safety Order 2005 calls them the responsible person: often the employer, owner or occupier. In shared or managed buildings, a landlord, facilities manager or managing agent can share the duty.

How far ahead should we book?

The more notice, the better, especially for out-of-hours work. Quotes typically come back within one working day, and there’s a 24/7 line for emergencies.
