Grease filter exchange for kitchens and businesses in Roxwell

Whether your canopy has baffle or mesh filters, they load up with grease. Clogged filters choke the airflow and the fan has to work harder. Regular exchange keeps the air moving. Typical jobs include a canopy running with filters missing and staff short of time to wash filters, across wall canopies, mesh filters and baffle filters.

In a small place like Roxwell, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. Access, parking and timings are agreed before the day.

Managing agents and facilities teams in Roxwell

If you look after several sites, we can schedule visits across all of them on one quote. Each site gets its own report and photos, so records stay tidy.

We also work for facilities teams across offices, schools and healthcare across Essex. Larger estates can be phased building by building around the people who use them.

Keeping the system healthy

How long the results last depends on use and care. We suggest:

  • Don’t refit a filter that is bent
  • Keep the extract on whenever the range is in use
  • Keep the canopy clear for exchange visits
  • Wipe the outside of the canopy as part of daily cleaning

Your next visit is scheduled before we leave. If the kitchen gets busier, the interval can be shortened to match.

If filters are already dripping, they’re overdue. A clean set straight away cuts the grease in the canopy, and it’s worth checking the plenum too.

Part by part

The plenum

Heavy grease in the plenum often follows clogged or missing filters, or that a full clean is due.

Baffle filters

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

What we are called out for in Roxwell

What a kitchen cooks affects how fast filters clog. Frying, grilling and chargrilling produce far more grease than steaming or baking, so the right exchange interval varies.

It’s time to book a visit if you see:

  • Drips falling from the filters onto equipment
  • Filters that come out of the sink still dirty
  • Staff short of time to wash filters
  • Bent or damaged filters that don’t sit properly

Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Chelmsford and Essex Hospital is the nearest hospital to Roxwell, about 3.9 miles south-east.

What your quote should include

  • When they can work, and whether that is outside your opening hours
  • If they look at the system before pricing
  • How they set the interval to the next visit
  • What’s included in the scope, part by part

Choosing a duct cleaning contractor

What your team can do, and what needs us

For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.

A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That is our job.

What we do, step by step

Your staff do not need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Afterwards, the area is left tidy and the written report follows. Visits to a village like Roxwell are booked in advance, at a time that suits whoever runs the site.

  1. We record the number, size and type of your filters.
  2. We set the interval with you.
  3. The dirty set is lifted out.
  4. Clean filters go in and we check they sit snugly.
  5. The dirty filters leave with us and the next visit is booked.

Before we arrive

  • Move anything stored near the system
  • Let us know when the site is closed or quiet
  • Let us know how we reach the system, including roofs, risers and plant rooms

Roxwell kitchens: local notes

Environmental health officers from Chelmsford council inspect food businesses in Roxwell. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A dated certificate in the maintenance file answers the question before it’s asked. Fire safety in Roxwell falls to Essex County 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.

A hall kitchen that only cooks for events, whether near Church of St Michael and All Angels or elsewhere in Roxwell, still needs its extract cleaned, just less often.

FAQs for Roxwell

Can you get to a site in Roxwell?

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

Do you work at weekends in Roxwell?

Yes, out-of-hours work is a big part of what we do. It means the site in Roxwell keeps running as normal. Tell us your opening hours when you ask for a quote.

How do you keep the site clean during the work?

With sheeting and covers, before anything else happens. The work is kept contained and clean down when we finish.

Is there a survey before the work?

Yes. For many sites, pictures and a few details are enough, while bigger or harder-to-see systems are surveyed on site.

What do you do with what you remove?

We contain it and take it with us. We collect grease, debris and waste water as we go, so it doesn’t spread.

Is TR19 cleaning required by law?

No. The law sets the duty; TR19® is the benchmark used to show it’s met. Under the Fire Safety Order 2005, the responsible person must reduce fire risk, and many insurers can refuse or reduce a claim without proof of cleaning.

What if some of our filters are damaged?

Damaged filters don’t seat properly and let grease through. We point them out on the visit and explain what’s needed.

What’s the right interval for changing filters?

That depends on the cooking. Heavy cooking means more frequent changes than kitchens that cook less. We set a schedule that suits your kitchen.

What grease filter exchange can’t fix

We will always give you a straight diagnosis, so here’s what grease filter exchange will not do:

  • Odours from the discharge that filters will not stop
  • A canopy too small for the cooking beneath it
  • Grease deep in the extract system

If in doubt, call 0345 646 2711, or email photos and we’ll say what we think.
