About our grease filter exchange in Picketts Lock

Filter exchange sits between full TR19® cleans. Clean filters reduce the grease reaching the ducts, but some grease still passes through as vapour. So the canopy, plenum and ducts still need their full TR19 clean. If you have a greasy plenum behind the filters and blocked baffle filters, we can put it right.

London kitchens tend to trade late and open early, so work in Picketts Lock is normally booked for the night or the early hours. Before the clean, we agree loading, parking and roof access with whoever manages the building.

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

Signs you need grease filter exchange in Picketts Lock

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.

The symptoms we are asked about most are:

  • Damaged filters letting grease past
  • Gaps where filters have been removed
  • Smoke and heat lingering under the hood
  • Drips falling from the filters onto equipment

If you run a church or community hall kitchen, near All Saints' Church or elsewhere in Picketts Lock, its extract still collects grease from every lunch and event.

Choosing a duct cleaning contractor

Grease filter exchange in Picketts Lock: the local picture

The FSA’s food hygiene register shows about 158 restaurants, cafés and canteens and about 79 takeaways and sandwich shops in and around Picketts Lock, up to about a mile and a half out. Swapping filters on a schedule keeps kitchens like these drawing air properly. Food hygiene inspections in Picketts Lock are the job of Enfield council’s environmental health team. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Most London extract cleaning happens at night, after the last service.

Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; North Middlesex University Hospital is the nearest hospital to Picketts Lock, about 2 miles south-west. If you run catering at a historic house or estate in the area (Bruce Castle is about 2.6 miles south-west), event kitchens in older buildings often have awkward duct runs that need planning.

What staff can safely do

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, next to our reports.

Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.

Your questions about grease filter exchange in Picketts Lock

Which fire service covers Picketts Lock?

London Fire Brigade is the fire and rescue service for Picketts Lock. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.

What do you need to know about parking in Picketts Lock?

A loading bay, a visitor permit or off-street space near the site in Picketts Lock makes the visit easier to plan. If the building has a loading slot system, we will book into it.

Is there a survey before the work?

Yes. For many sites, pictures and a few details are enough, while bigger or harder-to-see systems are surveyed on site.

What paperwork should we keep on file?

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

Do you take the used filters away?

We take them away. That is how an exchange works: you always have a clean set fitted and nothing greasy left on site.

How much does a filter exchange service cost?

The cost depends on your filters and the schedule. We’ll send you a fixed quote once we know your canopies.

Which sectors do you work in?

We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.

What is TR19?

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

What affects the quote in Picketts Lock

We don’t publish a price list, because no two systems are the same. What we look at:

  • When the work can happen, such as evenings, overnight or weekends
  • Travel, parking and unloading
  • The condition of the system
  • A single visit or a regular plan

When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote, and the price is fixed before work begins.

What to send for a quote

Photos let us diagnose from a distance. The most useful are:

  • How we’d reach plant on a roof or in a plant room
  • The paperwork from the last visit, if you have it
  • Problems your staff have spotted
  • Close-ups of filters, grilles, hatches or access panels

Quoting starts with a diagnosis, from your pictures and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work, before we start.

How the visit works

There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Afterwards, the area is left tidy and the written report follows. Expect the work in Picketts Lock to happen after your last customer leaves, not during trading.

  1. We count and measure the filters in every canopy.
  2. We agree a schedule that suits how much the kitchen cooks.
  3. At every visit, the greasy filters are lifted out.
  4. We fit clean filters and check they sit snugly in the housing.
  5. We flag any damaged filters or anything wrong with the canopy.

Before we arrive

  • Let us know when the site is closed or quiet
  • Let us know how we reach the system, including roofs, risers and plant rooms
  • Allow time for equipment near the work to be turned off and cool down

Getting a quote

We don’t publish a price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, and then send you a fixed quote. To get going, phone us on 0345 646 2711 or email us.

Keeping the system healthy

After the visit, a few habits help the work last:

  • Always run the extract while cooking
  • Keep filter exchange and TR19 cleaning on the same plan
  • Tell us if a filter is bent or damaged
  • Clean the canopy surfaces regularly

Nothing changes for your staff, except one less greasy job. Make sure we can reach the canopy on exchange day and let us know of any changes to opening hours.

Saturated filters let more grease through. Getting onto a regular exchange now keeps grease out of the plenum and ductwork until the next TR19 clean.

Honest limits

We will not sell you work that does not address the problem, so here are the limits:

  • Grease already built up in the ductwork, which needs a full TR19 clean
  • An extract that was undersized from the start
  • A canopy that needs a proper clean

If in doubt, give us a ring on 0345 646 2711 or send us an email and we’ll say what we think before booking.

What we work on in Picketts Lock

Why it’s worth doing now in Picketts Lock

Dripping canopies and greasy smells often start with the filters. Drips land on surfaces and equipment below, which an EHO may well notice. A building in Picketts Lock may have flats or offices above and alongside, and a fault in the system can affect them too.

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 make a difference.

  • Evenings, overnight and weekends, plus 24/7 emergency callout
