Grease filter exchange for sites in Harwell

Grease filter exchange for kitchens and businesses in Harwell

Whether your canopy has baffle or mesh filters, they load up with grease. Once they’re clogged, airflow drops and the fan has to work harder. A steady cycle of clean filters keeps extraction strong. Typical jobs include missing filters in the filter bank and drips falling from the filters onto equipment, on wall canopies, baffle filters and mesh filters.

For a smaller kitchen near Harwell, a TR19® clean is the same job as anywhere: canopy, filters, plenum, duct, fan and discharge. We plan the visit around your hours, with the journey sorted in advance.

Think of the report as the system’s health record: a dated account with photos of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

Kitchen extracts in Harwell

The FSA’s food hygiene register shows about 17 cafés, restaurants and staff canteens and about 4 sandwich bars and takeaways within roughly a mile and a half of the centre of Harwell. Any of those kitchens with a canopy relies on its filters to catch grease before it reaches the duct. In Harwell, food businesses are inspected by environmental health officers from Vale of White Horse council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Before-and-after pictures from each clean are a simple way to show the extract is in hand. Harwell sits within the area of Oxfordshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.

Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Abingdon Community Hospital is the nearest hospital to Harwell, about 4.8 miles north. Bursars and site managers at schools such as Harwell Primary School tend to book extract cleaning for when the kitchen is empty. Where a hall near Church of St Matthew, or anywhere in Harwell, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

Staff cleaning versus specialist work

If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.

Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.

What we do, step by step

Night work is normal for us. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. On site, the work takes less than an hour in most kitchens. Your opening hours decide when we come to Harwell, not ours.

  1. We count and measure the filters in every canopy.
  2. Together we set how often the filters should be changed.
  3. On each visit, the dirty filters come out of the canopy.
  4. Clean, dry filters are fitted in their place, with no gaps left between them.
  5. We flag any damaged filters or anything wrong with the canopy.

Getting ready for the visit

  • Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
  • Let us know about parking and loading
  • Tell us the best time to work, such as after service or at a weekend

Ask for a quote

Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

What happens if it’s left?

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. Even a site near Harwell that is only busy part of the week needs its system checked on a schedule.

Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at and we will price it together.

Why us?

  • A single point of contact for sites across the South East and London
  • Fully insured
  • Work around your opening hours, with 24/7 emergency cover
  • Trading since 2009

How we price grease filter exchange

We don’t publish a price list, because sites vary so much. The quote depends on:

  • What state the system is in
  • Whether we need access equipment or extra panels
  • Site requirements such as sign-in and permits
  • A single visit or a regular plan

Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.

Asking for a quote

To help us quote quickly, please include:

  • A few general shots of the system
  • How we’d reach plant on a roof or in a plant room
  • The site address and the type of premises
  • Any access panels or hatches you can see

Here’s what helps us quote: where the site is, what it is and its opening hours, photos of the system and any previous report or certificate. Then call 0345 646 2711 or email us.

Managing agents and facilities teams in Harwell

Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.

Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.

Common questions in Harwell

Will you come out to Harwell?

Yes. Harwell is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Do you work at weekends in Harwell?

Yes. We work evenings, overnight and at weekends. That way a site in Harwell does not have to lose a day’s trading. Tell us your opening hours when you ask for a quote.

What’s TR19?

It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.

Do you clean filters as well as exchanging them?

We can. Some kitchens prefer their own filters cleaned on a schedule, and others prefer a straight swap. We make sure the canopy is ready for service either way.

What does grease filter exchange cost?

We price it on the number of filters and the visit frequency. Send us details or pictures and we’ll quote, typically within one working day.

Do you take the used filters away?

They leave with us. That is the point of an exchange: you always have a clean set fitted and nothing greasy left on site.

Do you deal with bent or broken filters?

Damaged filters do not seat properly and let grease through. We flag any we find so they can be replaced.

What’s the right interval for changing filters?

It varies with the type and amount of cooking. If filters are dripping or clogging before the next change, it’s too long, and we can change it.

Part by part

The plenum

With good filters, less grease ends up in the plenum, but it still needs cleaning as part of TR19.

Mesh filters

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

What a clean will not put right

We won’t sell you work that doesn’t address the problem, so these are the things it will not cover:

  • Extraction problems caused by the fan rather than the filters
  • A canopy too small for the cooking beneath it
  • Greasy ducts and risers that a filter change won’t reach

If in doubt, give us a ring on 0345 646 2711, or send details by email and we will say what we think before booking.
