Grease filter exchange near Hanscombe End

About our grease filter exchange in Hanscombe End

A filter service works alongside TR19® cleaning, not instead of it. 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. The work covers baffle filters, wall canopies and restaurants and pubs, and the jobs we see most are filters that leave gaps in the canopy and grease left in baffles after washing.

Work in a small place like Hanscombe End starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.

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

When to call us in Hanscombe End

Filters get bent and damaged with handling. Damaged filters don’t sit flush, leaving gaps for grease to slip through.

Clients typically contact us after spotting one of these:

  • Grease filters clogged with grease
  • Poor airflow through the filters
  • A canopy running with filters missing
  • Filters that leave gaps in the canopy

If you run catering at a healthcare site, such as a hospital like Keech Hospice Care about 5.2 miles south-west, the extract may need cleaning more often than a part-time kitchen.

Our hiring checklist

What the work involves, part by part

Baffle filters

Baffle filters are robust and widely used in commercial canopies. They do not clean themselves, because the grease they collect builds up.

Canopy filter housings

Every exchange includes a check of how the filters sit since a gap is a route for grease.

What happens if it’s left?

Clogged filters choke the extract. Heat and fumes hang in the kitchen, and the fan works harder to pull air through. Keeping filters clean keeps the extract working properly. Our emergency line runs 24/7, but a planned visit to Hanscombe End is calmer for everyone.

Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered and we’ll price it together.

Why book with us

  • In business since 2009

Multi-site and managed buildings

Whether it’s one building or many, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with pictures.

When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.

Hanscombe End kitchens: local notes

In Hanscombe End, food businesses are inspected by environmental health officers from Central Bedfordshire council. Extraction counts as kitchen equipment, so its condition can come up on the day. A dated certificate in the maintenance file answers the question before it’s asked. Fire safety in Hanscombe End falls to Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.

Church and community hall kitchens, near Church of All Saints or anywhere around Hanscombe End, are easy to forget, but their extracts collect grease like any other. If you look after a school kitchen, at a school such as Shillington Lower School or anywhere near Hanscombe End, the holidays are the usual time for a TR19® clean.

Looking after it afterwards

Once we have finished, these simple steps help:

  • Keep the canopy clear for exchange visits
  • Keep the extract on whenever the range is in use
  • Report a dripping canopy early
  • Let us know if your cooking hours increase

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

A kitchen that’s getting busier needs its filters changed more often. Adjusting the schedule now prevents a build-up behind the canopy.

Common questions in Hanscombe End

Which fire authority looks after Hanscombe End?

Hanscombe End is in the area of Hertfordshire 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.

Do you cover smaller places like Hanscombe End?

Yes, Hanscombe End is part of our area, however small the site. Just mention lanes, gates or anything else about the site when you book.

How do you protect the area?

Floors and surfaces near the work are sheeted before work begins, and anything we remove is contained. At the end, the area is cleaned down.

What types of premises do you cover?

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

What should go in our maintenance log?

Visit reports, certificates and your in-house cleaning logs. Insurers, fire officers and EHOs may all ask to see them, so keep them where they can be found quickly.

What happens to the waste?

Waste is contained during the work and removed when we leave, including grease, debris and dirty water. We do not leave it behind.

Is there a survey before the work?

Yes. We always survey first, either from photos and details you send or on a site visit. Then you get a fixed quote.

Will I get paperwork for my records?

Yes. You get a written report with pictures after each visit, showing what was done, anything we couldn’t reach and when the next visit is due. Kitchen extract cleans to TR19® Grease also get a certificate through the BESCA Vent Hygiene Elite portal.

Honest limits

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

  • Odours from the discharge that filters won’t stop
  • A canopy that needs a proper clean
  • Extraction problems caused by the fan rather than the filters

Not sure which it is? You can phone us on 0345 646 2711 or email us and we will tell you honestly.

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

What we do, step by step

We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool first, and the area around the work is covered and protected. On site, it takes a few minutes per canopy, longer for a large kitchen with several canopies. A quick note on how to find the site and where to park makes a visit to Hanscombe End run smoothly.

  1. We record the number, size and type of your filters.
  2. We set the interval with you.
  3. On each visit, we remove the greasy filters.
  4. A clean set is fitted and checked for gaps.
  5. The dirty filters leave with us and the next visit is booked.

How to prepare

  • Mention any locked doors, roof access or ceiling voids
  • Dig out any earlier paperwork for the system
  • Name a contact who can let us in at the agreed time
