Grease filter exchange near Borehamwood

Different parts, different methods

The plenum

Heavy grease in the plenum often follows clogged or missing filters or that the next TR19 clean is due.

Baffle filters

Baffle filters use overlapping metal blades that force the air to change direction. Grease drops out as it does.

About our grease filter exchange in Borehamwood

Cleaning filters by hand takes staff time and is easy to put off. An exchange service means clean filters arrive and greasy ones leave and the canopy is refilled right away. Typical jobs include grease left in baffles after washing and poor airflow through the filters, across island canopies, mesh filters and wall canopies.

Most kitchens in a town like Borehamwood cannot close for a day, so cleans are booked after closing, early in the morning or on a quiet day. The kitchen is handed back clean and ready to cook.

Nothing is signed off by word of mouth: a dated report with photos 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.

Landlords, agents and facilities managers

We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we’re happy to quote for all of it.

Whether it’s one building or many, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with pictures.

Why act early in Borehamwood

Filters full of grease are fuel sitting right above the cooking. A flare-up on the range can reach them and grease in the duct can carry a fire further. Keeping filters clean takes some of that fuel away. In a town like Borehamwood, a problem caught early is a planned visit, not an emergency.

When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote and give you a fixed price before any work starts.

Keeping the system healthy

Looking after the system between visits is straightforward, and it helps at the next visit:

  • Look out for drips from the canopy
  • Let us know if your cooking hours increase
  • Clear anything stored on or near the canopy
  • Never cook with the extract switched off

We tell you if we spot anything in the canopy that needs attention. It can be a sign that a full TR19® clean is due, and we can arrange it.

Damaged filters leave gaps in the defence. Replacing them early protects the plenum and ductwork.

Common questions in Borehamwood

Who carries out food hygiene inspections in Borehamwood?

The local authority for Borehamwood is Hertsmere council, and its environmental health team does the inspecting. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.

Who is the fire and rescue service for Borehamwood?

That’s Hertfordshire Fire and Rescue Service. TR19® is not law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.

Will I get paperwork for my records?

Yes. It’s the record insurers and inspectors ask to see: a dated report with pictures, listing the work and any areas we couldn’t reach.

Can you clean our existing filters instead?

Yes. Some kitchens prefer their own filters cleaned on a schedule while others want an exchange. We make sure the canopy is ready for service either way.

Do you take the used filters away?

Yes. Used filters go with us to be cleaned and the clean set stays in the canopy.

What happens if you can’t reach some of it?

We never leave them off the paperwork. You will know exactly which parts weren’t reached and why, and we can quote to improve the access.

How much notice should we give?

That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and for anything urgent, ring our 24/7 emergency line.

Can you set up regular visits?

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

What your team can do, and what needs us

When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.

Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.

What affects the quote in Borehamwood

We quote each job individually. These are the things that affect it:

  • How big the system is
  • Whether we need access equipment or extra panels
  • The condition of the system
  • Where the site is and how we reach it

Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at and we’ll price it together.

Helping us quote

What to send for a quote:

  • Any symptoms, from odd noises to smells or leaks
  • The times we could work without disrupting the site
  • Close-ups of filters, grilles, hatches or access panels
  • The paperwork from the last visit, if you have it

Want a quote for grease filter exchange? Please give us a ring on 0345 646 2711, or send details by email with a few details about the site. We will talk you through the work and give you a fixed quote before you commit to anything.

How the visit works

We work around your opening hours, not the other way round. 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 a short visit, depending on how many filters the canopies hold. The more we can see of the system beforehand, the smoother the visit to Borehamwood will be.

  1. We look at the canopies and the condition of the filters.
  2. We note any filters that are bent, damaged or missing.
  3. Greasy filters are swapped for clean ones.
  4. The filters are checked for fit before we go.
  5. Anything that needs attention, such as a greasy plenum, is pointed out.

Before we arrive

  • Plan for cooking equipment or plant to be off before we arrive
  • Tell us where we can park and unload
  • Make sure someone can let us in and lock up afterwards

How to get a quote

The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
