How we price grease filter exchange

The price is fixed before any work begins. It takes into account:

  • The condition we find in the survey
  • Site requirements such as sign-in and permits
  • How big the system is
  • The number of sites or systems

You will not find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we will talk you through it.

What we need to know

Many jobs can be priced from pictures and some basics. Useful things to send:

  • Any symptoms, from odd noises to smells or leaks
  • Photos showing the whole system and its surroundings
  • Your opening hours and when the area is out of use
  • The paperwork from the last visit, if you have it

Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.

Grease filter exchange in Offham, done properly

Across Offham, our filter exchange suits restaurants, pubs, cafés, schools, care homes and other kitchens, from a single canopy to several. We can come before or after service, so cooking is not interrupted. If you have damaged filters letting grease past and grease left in baffles after washing, we can put it right, from baffle filters, wall canopies and restaurants and pubs onwards.

Somewhere as small as Offham, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Every one of them still needs its extract kept clear of grease.

The report is your system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

What the work involves, part by part

Canopy filter housings

The trough or channel under the filters fills with grease. If it needs attention, we will tell you.

The plenum

The plenum is the space behind the filters. It collects whatever grease the filters miss.

Honest limits

Not every problem is solved by grease filter exchange, and we’d rather say so up front. It does not solve:

  • Cooking smells reaching neighbours, which need odour control
  • A canopy that needs a proper clean
  • Greasy ducts and risers that a filter change won’t reach

Not sure which it is? You can call 0345 646 2711, or send details by email and we will tell you honestly.

Where we work

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

How it works

We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes less than an hour in most kitchens. Rural roads and tight entrances are worth telling us about before a visit to Offham.

  1. We count and measure the filters in every canopy.
  2. A change schedule is agreed to match the kitchen’s cooking hours.
  3. Each visit starts with the used filters being removed.
  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.

Preparing for the visit

  • Mention any locked doors, roof access or ceiling voids
  • Tell us about site rules, permits or sign-in
  • Name a contact who can let us in at the agreed time

Getting a quote

Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

Advice

Grease filter exchange in Offham: the local picture

Food Standards Agency data counts about 20 restaurants, cafés and canteens and about 3 takeaways in Offham and the streets around it, up to about 1.5 miles out. Where they cook under a canopy, the grease filters are the first line of defence and clog quickly. Offham sits within the area of Kent 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 in Offham get their food hygiene inspections from Tonbridge and Malling council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Our report lists what was cleaned and when, which is useful to have ready.

If you look after a school kitchen, at a school such as Offham Primary School or anywhere near Offham, the holidays are the usual time for a TR19® clean. Healthcare kitchens, like those at hospitals such as Maidstone Hospital (about 4.8 miles east), often cook for long hours, which puts them in BESA’s heavier-use bands.

Common problems we fix in Offham

Sometimes a filter is taken out and never put back. Every gap in the filter bank lets grease straight into the plenum and on into the ductwork.

Keep an eye out for these warning signs:

  • Weak extraction at the canopy
  • A canopy that drips grease
  • Bent or damaged filters that don’t sit properly
  • Grease filters clogged with grease

Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Old Soar Manor is about 3.1 miles south-west), access may need planning.

How to choose an extract cleaning contractor

What happens if it’s left?

In Offham, as everywhere, a filter service isn’t a substitute for TR19 cleaning. They do help keep the system in better shape between cleans and the canopy and plenum stay cleaner. A fault that closes a site in a village like Offham affects everyone who depends on it.

One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. You’ll have a fixed price before work begins.

Why us?

  • Every visit written up, with photos
  • Ventilation hygiene specialists since 2009
  • Survey first, then a fixed quote
  • We are fully insured

See our cost guide or how to check a contractor.

In-house cleaning or a specialist?

Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.

Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.

Common questions in Offham

Do you do school kitchen extract cleaning in Offham in the summer holidays?

Yes, and it’s the easiest time to do it. Around Offham, the Food Standards Agency lists about 6 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we’ll book the visit for when the site is empty.

Is Offham within the area you cover?

Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.

Do you take the used filters away?

We take them away. That’s how an exchange works: clean filters in, dirty ones out, with no washing for your team.

Do you have insurance?

Yes. We’re fully insured, and the details are available on request.

What does grease filter exchange cost?

It depends on the number and type of filters and how often they’re changed. Just call 0345 646 2711 or use the quote form for a fixed quote once we know your canopies.

What do you do to protect the area?

Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.

How long will you be on site?

That depends on the amount of work, but for a typical site it takes less than an hour in most kitchens. We’ll confirm it with the quote.

Can damaged filters stay in the canopy?

We check every filter at each visit. Any that are bent or damaged are flagged, because gaps let grease into the plenum.
