Grease filter exchange near Coombe

What staff can safely do

Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.

Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.

Grease filter exchange for kitchens and businesses in Coombe

We run grease filter exchange for all kinds of kitchens in Coombe, whether there’s one canopy or many. Visits can be timed around your service, so cooking is not interrupted. Common call-outs are for staff short of time to wash filters and grease dripping from the canopy, on school and hospital kitchens, wall canopies and mesh filters.

Somewhere as small as Coombe, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Every one of them still needs its extract kept clear of grease, whatever the size of the place.

Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Keeping the system healthy

Looking after the system between visits is straightforward, and it makes the next visit easier:

  • Tell us if a filter is bent or damaged
  • Wipe the outside of the canopy as part of daily cleaning
  • Keep every filter in place during service
  • Mention it if the kitchen gets busier

Fresh filters improve airflow at the canopy right away. Always run the extract during cooking so they catch grease as intended.

Filters that are left too long stop protecting the system. Getting onto a regular exchange now keeps grease out of the plenum and ductwork between full cleans.

Signs you need grease filter exchange in Coombe

What a kitchen cooks affects how fast filters clog. Fryers, grills and woks load filters faster than ovens and steamers, so the right exchange interval varies.

The symptoms we are asked about most include:

  • Grease filters clogged with grease
  • Filters left unwashed on busy weeks
  • Drips falling from the filters onto equipment
  • Damaged filters letting grease past

Volunteers running a hall kitchen near Church of St Peter and St Paul, or anywhere in Coombe, may not know when the extract was last cleaned, and a grease test settles it.

Before you book anyone

  • When they can work, and whether that’s outside your opening hours
  • How they set the interval to the next visit
  • Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
  • Whether inaccessible sections are listed on the report

Coombe questions

Do you work overnight in Coombe?

Yes, evening, overnight and weekend work is normal for us. That way a site in Coombe does not have to lose a day’s trading. When you give us a ring on 0345 646 2711, or email photos, mention when the site is quiet.

Do you work in villages like Coombe?

Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.

What does TR19 mean?

TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.

Do you deal with bent or broken filters?

Each filter is looked at when we exchange. Any that are bent or damaged are flagged since a poor fit lets grease past.

What accreditations do you have?

Our accreditations are CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.

Which records should we keep?

Every certificate and report from each visit, kept together in your maintenance log with your in-house cleaning records. BESA says certificates should show the date, location and technician.

Which kinds of sites do you work on?

We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.

What’s the right interval for changing filters?

The right interval depends on the kitchen. If filters are dripping or clogging before the next change, it’s too long and we’ll adjust it.

Managing agents and facilities teams in Coombe

From a single site to a large estate, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.

Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.

What we do, step by step

Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes anything from a few minutes to an hour or so, depending on the number of filters. A quick note on how to find the site and where to park makes a visit to Coombe run smoothly.

  1. The filters in each canopy are measured and counted.
  2. We set the interval with you.
  3. On each visit, we remove the greasy filters.
  4. Clean filters go in and we check they sit snugly.
  5. We take the greasy set away and confirm the next date.

Preparing for the visit

  • Clear loose items from the work area
  • Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
  • Mention any sign-in, permit or induction we need

How to get a quote

We don’t publish a price list, because every site is different. We look at your system first, from photos or on a visit, then send a fixed quote. To start, call 0345 646 2711, or send details by email.

Grease filter exchange in Coombe: the local picture

There are about 7 restaurants, cafés and works canteens within about 1.5 miles of central Coombe, according to the Food Standards Agency’s register. Swapping filters on a schedule keeps kitchens like these drawing air properly. Buckinghamshire Fire and Rescue Service covers Coombe. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. It’s Buckinghamshire council that sends environmental health officers to food businesses in Coombe. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Before-and-after photos from each clean are a simple way to show the extract is in hand.

School kitchens, at schools like Great Kimble Church of England School for example, are normally cleaned in the holidays so no lunches are lost. A hospital like Stoke Mandeville Hospital, about 3.5 miles north, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

What grease filter exchange cannot fix

A few issues sit outside what this work can do:

  • A fan that’s failing or too weak for the system
  • A canopy that needs a proper clean
  • Odours from the discharge that filters will not stop

If you are not sure, just call us on 0345 646 2711, or email photos and we will give you a straight answer before you book.

What the work covers

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

How the job changes from site to site

Baffle filters

A clogged baffle filter restricts airflow. A clean exchange set brings the airflow back.

Mesh filters

Grease lodges deep in the layers of a mesh filter, which makes hand-washing hard work.
