Grease filter exchange in Cobham

Grease filter exchange in Cobham

Good filters only work when they fit properly. Gaps in the filter bank are a direct route into the plenum and every filter is checked when we swap them. We point out any that need replacing. The work covers baffle filters, restaurants and pubs and island canopies, and the jobs we see most are blocked baffle filters and damaged filters letting grease past.

Somewhere as small as Cobham, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Each still has a canopy and duct that collect grease, whatever the size of the place.

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.

Grease filter exchange around Cobham

There are about 5 restaurants, cafés and works canteens within 1.5 miles or so of the middle of Cobham, according to the Food Standards Agency’s register. Clogged filters slow the airflow, and busy kitchens like these clog them fast. It’s Gravesham council that sends environmental health officers to food businesses in Cobham. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Before-and-after pictures from each clean are a simple way to show the extract is in hand. The fire and rescue service for Cobham is Kent Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.

Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Gravesham Community Hospital is the nearest hospital to Cobham, about 3.9 miles north-west. If your kitchen is in a listed or historic building, like the houses around Cobham (Cobham College is about 0.2 miles south-west), fitting access panels needs care.

What the work involves, part by part

Canopy filter housings

Grease collects in the channels and drip trays below the filters. We point it out if it needs cleaning.

Baffle filters

Baffle filters are robust and widely used in commercial canopies. They don’t clean themselves, because the grease they collect builds up.

Common questions in Cobham

Do you clean school canteen extracts around Cobham out of term?

Yes, holiday work suits schools best. There are about 4 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Cobham. Just give us a ring on 0345 646 2711 or email us with your term dates and we will plan around them.

Do you cover smaller places like Cobham?

Yes. Villages and rural sites across the South East are part of our work, Cobham included. Let us know about access, parking and anything unusual about getting there when you book.

Are you insured?

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

Does a filter exchange disrupt service?

Most changes take less than an hour in most kitchens, so the impact is small. We will fit it around your service wherever we can.

How regularly do grease filters need exchanging?

There’s no single answer. We look at your cooking and set an interval to match, and adjust it if needed.

How much does a filter exchange service cost?

Pricing depends on the kitchen, so we quote once we know your filters and schedule. You get a fixed price before the first visit.

Can you look after several sites?

Yes. We work across South East England and London, so we can schedule a run of sites on one programme. Each site gets its own report and photos.

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 so they can be replaced.

When to call us in Cobham

Wherever you are, Cobham included, filter washing is the job that gets skipped when the kitchen is busy. A missed wash or two is all it takes for a filter bank to clog.

What we are most often called out for:

  • Bent or damaged filters that don’t sit properly
  • Weak extraction at the canopy
  • Grease left in baffles after washing
  • Missing filters in the filter bank

Church and community hall kitchens, near Parish Church of St Mary Magdalene or anywhere around Cobham, are easy to forget, but their extracts collect grease like any other.

What to look for in a quote

  • What paperwork you get at the end
  • Whether the work can be done while the site is closed
  • Whether a survey comes first
  • When the next visit should be, and why

How to choose an extract cleaning contractor

When it’s something else

To be straight with you, some problems need a different fix:

  • Grease already built up in the ductwork, which needs a full TR19 clean
  • A noisy or failed extract fan
  • A canopy that doesn’t capture the vapour properly

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

How it works

Your trading hours come first. 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 work takes anything from a few minutes to an hour or so, depending on the number of filters. In a small place like Cobham, the journey is planned ahead and the visit arranged around the site’s hours.

  1. We count and measure the filters in every canopy.
  2. A change schedule is agreed to match the kitchen’s cooking hours.
  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. If a filter is damaged or the plenum needs attention, we tell you.

Getting ready for the visit

  • Allow time for equipment near the work to be turned off and cool down
  • Let us know when the site is closed or quiet
  • Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

Ask for a quote

Quoting starts with a diagnosis, from your photos and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work, before any work starts.

What affects the quote in Cobham

Sites vary more than people expect. What affects the quote:

  • Any permits to work or inductions
  • One-off work versus a regular cycle
  • How big the system is
  • Access, including roofs, risers and ceiling voids

Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered, and you will get one fixed quote.

Asking for a quote

Photos and a few facts are often enough to price the work. Useful things to send:

  • The times we could work without disrupting the site
  • How we’d reach plant on a roof or in a plant room
  • Close-ups of filters, grilles, hatches or access panels
  • The site address and the type of premises

Quotes are quick. Send a few details and photos, and we usually reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.

Leave it or put it right?

Some kitchens in Cobham wash filters themselves to save the cost of a service, and that can work if it’s done thoroughly and on time. When it doesn’t happen reliably, an exchange makes it automatic. Rural sites can’t always move to another kitchen or room when something fails.

A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. You’ll have a fixed price before we start.

What you get with us

  • Full insurance on every job
  • Survey first, then a fixed quote
  • Each visit written up, with photos
  • Evenings, overnight and weekends, plus 24/7 emergency callout

In-house cleaning or a specialist?

For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.

Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
