Questions from Sevenoaks

Can a school canteen extract in Sevenoaks be done out of term time?

Yes. Half-terms and the summer break are the natural time for school work. Around Sevenoaks, the Food Standards Agency lists about 18 schools and colleges with registered kitchens within a mile and a half or so. Booking early in the term gives the best choice of holiday dates.

Do you work at weekends in Sevenoaks?

Yes. We work evenings, overnight and at weekends. That way a site in Sevenoaks doesn’t have to lose a day’s trading. When you phone us on 0345 646 2711 or send us an email, mention when the site is quiet.

Does a filter exchange replace TR19 cleaning?

No. Filters don’t catch everything, so grease still reaches the ductwork and the whole system still needs its TR19 clean.

What if parts of the system can’t be reached?

We record them on the report, with a note of where it is, and we tell you what would make it reachable, such as extra access panels in ductwork.

How long will you be on site?

That depends on how much there is to do, but for many sites it takes less than an hour in most kitchens. We’ll give you a better idea when we quote.

What should go in our maintenance log?

Anything that proves the system is maintained: our reports and pictures, any certificates and your in-house logs. One maintenance log per site keeps it simple.

Do you work with multi-site operators?

Yes. Our area covers London and the South East, so we can schedule a run of sites as one programme. Each site gets its own report and pictures.

Do I get a report after the visit?

Yes. You get a written report with photos after every visit, covering the work, any areas we couldn’t access and the recommended next date. Kitchen extract cleans to TR19® Grease also get a certificate through the BESCA Vent Hygiene Elite portal.

Grease filter exchange for kitchens and businesses in Sevenoaks

Washing filters in the kitchen sink is messy and easily missed on a busy week. An exchange service means clean filters arrive and greasy ones leave, so the canopy is never left without filters. If you’re dealing with drips falling from the filters onto equipment and filters left unwashed on busy weeks, we can put it right.

Kitchens in towns like Sevenoaks are often in older buildings that were never designed for them, so duct runs can be awkward, with bends, long horizontal sections and too few access panels. Where the duct can’t be reached, new panels can be fitted, and anything left uncleaned is recorded on the report.

Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What grease filter exchange cannot fix

In fairness, some problems need a different fix:

  • An extract that was undersized from the start
  • Odours from the discharge that filters won’t stop
  • Greasy ducts and risers that a filter change will not reach

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

Parts of the system we cover

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

What your team can do, and what needs us

Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.

Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.

Keeping the system healthy

Think of this as the after-treatment advice, short and simple:

  • Mention it if the kitchen gets busier
  • Keep canopy surfaces wiped down
  • Look out for drips from the canopy
  • Make sure no filter is left out

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 book that in.

Clean filters plus regular full cleans keep the system in good health. Setting both up on a schedule means neither slips.

When to call us in Sevenoaks

The type of cooking matters. Frying, grilling and chargrilling produce far more grease than steaming or baking, so the right exchange interval varies.

The symptoms we are asked about most are:

  • A canopy that drips grease
  • Filters that leave gaps in the canopy
  • Missing filters in the filter bank
  • Weak extraction at the canopy

Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Sevenoaks Hospital is the nearest hospital to Sevenoaks, about 0.6 miles north-east.

What your quote should include

  • Whether they recommend a next date
  • What paperwork you get at the end
  • Whether the quote shows VAT
  • If the quote is a fixed price or an estimate

Questions to ask before you book

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 work takes a short visit, depending on how many filters the canopies hold. A few pictures of the system and its access points help us plan a visit in Sevenoaks.

  1. First, we check the canopies and the filters in them.
  2. Any damaged or missing filters are noted.
  3. Greasy filters are swapped for clean ones.
  4. We check the filters are seated and the canopy is ready to use.
  5. Anything that needs attention, such as a greasy plenum, is pointed out.

Preparing for the visit

  • Clear loose items from the work area
  • Make sure equipment near the work can be switched off and left to cool
  • Let us know about permits to work or site inductions

Ask for a quote

Sevenoaks kitchens: local notes

The FSA’s data shows about 13 bars, pubs and nightclubs and about 3 hotels and B&Bs registered in Sevenoaks and the streets around it, up to about 1.5 miles out. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Food hygiene inspections in Sevenoaks are the job of Sevenoaks council’s environmental health team. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A dated certificate in the maintenance file answers the question before it’s asked. Sevenoaks is covered by Kent 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.

A kitchen near Sevenoaks station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval. A hall kitchen that only cooks for events, whether near St John the Baptist or elsewhere in Sevenoaks, still needs its extract cleaned, just less often.

What affects the cost of grease filter exchange

A fixed price needs a few facts first. We check:

  • The size of the system
  • Whether several sites go on one quote
  • When the work can happen, such as evenings, overnight or weekends
  • Where the site is and how we reach it

No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.

What we need to know

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

  • Any access panels or hatches you can see
  • Your opening hours and when the area is out of use
  • The paperwork from the last visit, if you have it
  • Problems your staff have spotted

We do not publish a price list, because no two systems are the same. We look at your system first, from photos or on a visit, and then give you a fixed quote. To get going, give us a ring on 0345 646 2711 or drop us a line.

Different parts, different methods

Mesh filters

Grease lodges deep in the layers of a mesh filter, so a quick rinse rarely gets it clean.

Canopy filter housings

Filters sit in a housing or channel in the canopy. A damaged housing leaves gaps.
