Grease filter exchange across Charlton

Grease filter exchange in Charlton, done properly

Baffle filters and mesh filters both fill with grease. Once they’re clogged, airflow drops and the fan has to work harder. A steady cycle of clean filters keeps extraction strong. If you’re dealing with filters that leave gaps in the canopy and grease collecting in the filter channels, we can put it right.

Kitchens around a place like Charlton are often in older buildings or single-storey extensions, with the duct running through a roof space or up an outside wall. Long horizontal runs like that hold grease and need access panels to reach.

Good records are part of the job. Each visit is written up with pictures, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

What your team can do, and what needs us

Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.

Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.

What affects the cost of grease filter exchange

The price is fixed before any work begins. It’s based on:

  • The size of the system
  • Working hours and out-of-hours timing
  • Where the site is and how we reach it
  • Whether we need access equipment or extra panels

What you pay depends on how big the system is, the condition it’s in and how easy it is to reach. You get a fixed price before any work starts, so you know where you stand.

Helping us quote

We can often survey from photos. The most useful are:

  • The times we could work without disrupting the site
  • Any symptoms, from odd noises to smells or leaks
  • Detail shots of panels, filters and grilles
  • Photos showing the whole system and its surroundings

If you need grease filter exchange in Charlton, give us a ring on 0345 646 2711 or drop us a line. Let us know the site type and the opening hours, plus photos or the previous report if they’re to hand. We usually send a fixed quote within one working day.

Grease, kitchens and Charlton

Food Standards Agency records list about 20 cafés, restaurants and staff canteens and about 10 takeaways within roughly a mile and a half of the centre of Charlton. Clogged filters slow the airflow, and busy kitchens like these clog them fast. Fire safety in Charlton falls to Oxfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. In Charlton, food businesses are inspected by environmental health officers from Vale of White Horse council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Before-and-after photos from each clean are a simple way to show the extract is in hand.

School kitchens, at schools like Charlton Primary School for example, are usually cleaned in the holidays so no lunches are lost.

What happens on the day

Each visit runs to the same pattern: sheeting and protection first, make the system safe, do the work, tidy up and hand over the paperwork. The visit itself takes well under an hour for most canopies. Everything the job in Charlton needs is worked out beforehand, from the survey.

  1. We start by noting how many filters you have and what type they are.
  2. We agree a schedule that suits how much the kitchen cooks.
  3. On each visit, the dirty filters come out of the canopy.
  4. We fit clean filters and check they sit snugly in the housing.
  5. If a filter is damaged or the plenum needs attention, we tell you.

Getting ready for the visit

  • Dig out any earlier paperwork for the system
  • Let us know about parking and loading
  • Tell us the best time to work, such as after service or at a weekend

Related advice

Different parts, different methods

Busy restaurant and pub kitchens

High-output kitchens clog filters quickly. They often need the shortest exchange interval.

Mesh filters

Mesh filters use layers of metal mesh to trap grease. They clog quickly in a busy kitchen and need frequent attention.

Managing agents and facilities teams in Charlton

Managing agents often deal with us directly. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.

When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.

Common questions in Charlton

Who inspects food businesses in Charlton?

Kitchens in Charlton are inspected by Vale of White Horse council’s environmental health officers. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.

Which fire authority looks after Charlton?

That is Oxfordshire Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.

Can we book visits on a schedule?

Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. Each report recommends when the next visit should be.

Do you survey before quoting?

Yes. Every job is surveyed first, either from pictures and details you send or on a site visit. A fixed quote follows.

Does the report say when we need you again?

Yes. Every report includes a recommended date for the next visit, based on use and what we found.

How often should grease filters be changed?

It varies with the type and amount of cooking. If filters clog early, the interval needs shortening and we’ll adjust it.

What about areas you cannot get to?

They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, along with a quote to put access in.

Do you clean filters as well as exchanging them?

Yes, filters can be cleaned on a schedule as well as exchanged. We’ll explain the options when we quote.

Looking after it afterwards

No system stays clean for ever, but care slows the build-up. A few tips:

  • Keep every filter in place during service
  • Wipe the outside of the canopy as part of daily cleaning
  • Clear anything stored on or near the canopy
  • Do not refit a filter that is bent

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.

Filters that are left too long stop protecting the system. Getting onto a regular exchange now keeps grease out of the plenum and ductwork between full cleans.

Common problems we fix in Charlton

Kitchens in Charlton, as everywhere, find filter washing slips down the list on busy weeks. It only takes a couple of missed weeks for filters to fill with grease.

What we are most often called out for:

  • Grease filters clogged with grease
  • Hand-washed filters that still look greasy
  • Grease collecting in the filter channels
  • A canopy that drips grease

If you run a church or community hall kitchen, near Holy Trinity Church or elsewhere in Charlton, its extract still collects grease from every lunch and event.
