Grease filter exchange in Northway

A filter that doesn’t sit right lets grease straight past. Bent, damaged or missing filters leave gaps and every filter is checked when we swap them. We point out any that need replacing. If you have grease building up behind the canopy filters and filters that leave gaps in the canopy, we can put it right, from island canopies, school and hospital kitchens and wall canopies onwards.

In a smaller place like Northway, the kitchens with extract systems are more likely to be a pub, a café, a takeaway or a school or care home kitchen than a big restaurant. A kitchen that cooks fewer hours still builds up grease, so the interval is set by hours of use and grease readings.

Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

What your team can do, and what needs us

Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.

Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.

How the visit works

There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and photos. The middle part takes longest, which takes a short visit, depending on how many filters the canopies hold. Getting to the system matters more than parking in a place like Northway, so let us know how to reach it.

  1. We record the number, size and type of your filters.
  2. An exchange schedule is agreed to suit your cooking.
  3. The dirty set is lifted out.
  4. A clean set is fitted and checked for gaps.
  5. The dirty filters leave with us and the next visit is booked.

Before we arrive

  • Have your last certificate or report to hand
  • Let us know how we reach the system, including roofs, risers and plant rooms
  • Clear the space around the work

Landlords, agents and facilities managers

We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.

We regularly work with managing agents. Tell us the site, the work and the access arrangements and we’ll come back with a fixed quote.

What a clean will not put right

Some problems need a different service or another trade:

  • Grease already built up in the ductwork, which needs a full TR19 clean
  • Extraction problems caused by the fan rather than the filters
  • A canopy too small for the cooking beneath it

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

What the work covers

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

When to call us in Northway

Missing filters are more common than you’d think. Every gap in the filter bank lets grease straight into the plenum where it settles out of sight.

Keep an eye out for these warning signs:

  • Filters that leave gaps in the canopy
  • Filter washing that keeps being missed
  • Gaps where filters have been removed
  • Grease left in baffles after washing

Historic houses near Northway, such as Holywell Manor about 1.5 miles south-west, are a reminder that older buildings with event kitchens can have long, awkward duct routes.

How to choose an extract cleaning contractor

Looking after it afterwards

Aftercare is simple, and it helps at the next visit:

  • Do not let the full clean slip because filters are changed
  • Make sure we can reach the canopy on exchange day
  • Let us know if your cooking hours increase
  • Keep canopy surfaces wiped down

Your team carries on as normal, without the filter washing. Make sure we can reach the canopy on exchange day and let us know of any changes to opening hours.

Clean filters plus regular full cleans keep the system in good health. Setting both up on a schedule keeps everything on track.

Part by part

Mesh filters

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

The plenum

Clean filters reduce the grease reaching the plenum, but it still needs cleaning as part of TR19.

Grease filter exchange around Northway

Food Standards Agency records include about 27 pubs and bars and about 5 hotels and B&Bs in and around Northway, up to about a mile and a half out. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Oxfordshire Fire and Rescue Service covers Northway. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. In Northway, food businesses are inspected by environmental health officers from Oxford City council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Before-and-after photos from each clean are a simple way to show the extract is in hand.

If you run catering at a healthcare site, such as a hospital like Churchill Hospital about 0.5 miles south, the extract may need cleaning more often than a part-time kitchen. If you run a church or community hall kitchen, near St Anthony of Padua or elsewhere in Northway, its extract still collects grease from every lunch and event.

Northway: your questions answered

Which council inspects kitchens in Northway?

That is Oxford City council, whose environmental health officers carry out food hygiene inspections in Northway. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.

Can school kitchens in Northway be cleaned in the holidays?

Yes, out-of-term visits are normal for schools. There are about 20 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Northway. Booking early in the term gives the best choice of holiday dates.

What does TR19 mean?

A BESA specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not legislation, but it’s the standard people check against.

Do you offer emergency callouts?

Yes, day and night, every day of the year. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.

Where does the waste go?

Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. None of it is left on site.

How long does the visit take?

It depends on the size of the system, but for a typical site it takes a short visit, depending on how many filters the canopies hold. We’ll give you a better idea when we quote.

What if some of our filters are damaged?

A bent filter leaves a gap for grease. We point them out on the visit and explain what’s needed.

What types of filter do you exchange?

Both baffle filters and mesh filters are covered. At the start, we note what your canopies use so the clean set always fits.
