Grease filter exchange in Brent Park: the local picture

Food Standards Agency records list about 193 cafés, restaurants and staff canteens and about 188 takeaways in Brent Park and the streets around it, up to about 1.5 miles out. Swapping filters on a schedule keeps kitchens like these drawing air properly. Overnight is the normal time to clean a London kitchen extract, so trading isn’t affected. In Brent Park, food businesses are inspected by environmental health officers from Brent council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Keeping each certificate and photo report on file helps show the extract is looked after.

Where a hall near Church of St Mary, or anywhere in Brent Park, hosts lunch clubs or events, its extract gathers grease just as a café’s does. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Neasden Hospital is the nearest hospital to Brent Park, about less than half a mile south. For schools such as Mitchell Brook Primary School, kitchen extract cleaning is typically booked for the holidays, when the canteen is closed.

About our grease filter exchange in Brent Park

An exchange visit in Brent Park does not take long. We lift out the dirty filters and fit a clean set, and we check they’re seated with no gaps. Anything that needs attention is pointed out. Common call-outs are for grease left in baffles after washing and filters so greasy the air can barely pass, on baffle filters, wall canopies and school and hospital kitchens.

In London, few kitchens can spare a day to close, so extract cleaning in Brent Park is typically done overnight, after the last service. Before the clean, we agree loading, parking and roof access with whoever manages the building.

We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Aftercare tips

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

  • Make sure no filter is left out
  • Never cook with the extract switched off
  • Tell us if a filter is bent or damaged
  • Keep the canopy clear for exchange visits

If the plenum behind the filters looks greasy, we say so. It can be a sign that a full TR19® clean is due, and we can arrange it.

Bent or missing filters let grease straight past. Sorting them now keeps grease where it can be caught.

What happens on the day

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. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes well under an hour for most canopies. Getting kit into a London building takes planning, so let us know where we can load and park in Brent Park.

  1. We count and measure the filters in every canopy.
  2. Together we set how often the filters should be changed.
  3. Each visit starts with the used filters being removed.
  4. We fit clean filters and check they sit snugly in the housing.
  5. Anything we notice, such as bent filters or a dirty plenum, is pointed out.

How to prepare

  • Have your last certificate or report to hand
  • Make sure someone can let us in and lock up afterwards
  • Plan for cooking equipment or plant to be off before we arrive

Related advice

Multi-site and managed buildings

Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.

Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.

Different parts, different methods

Mesh filters

Mesh traps grease between its layers, which makes hand-washing hard work.

The plenum

The plenum is the space behind the filters. Grease that gets past the filters settles there.

What affects the cost of grease filter exchange

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

  • Site requirements such as sign-in and permits
  • What state the system is in
  • A single visit or a regular plan
  • The size of the system

One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. You will have a fixed price before work begins.

Helping us quote

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

  • Close-ups of filters, grilles, hatches or access panels
  • Any symptoms, from odd noises to smells or leaks
  • Your opening hours and when the area is out of use
  • The site address and the type of premises

Some systems can be priced from pictures; others need a survey. 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.

Brent Park questions

Who carries out food hygiene inspections in Brent Park?

The local authority for Brent Park is Brent council, and its environmental health team does the inspecting. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.

Which fire and rescue service is responsible for Brent Park?

Brent Park is in the area of London Fire Brigade. TR19® isn’t law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.

What should go in our maintenance log?

Visit reports, certificates and your in-house cleaning logs. Insurers, fire officers and EHOs may all ask to see them, so keep them together and easy to find.

What if some of our filters are damaged?

Damaged filters don’t seat properly and let grease through. We flag any we find and explain what’s needed.

Can we skip TR19 cleans if the filters are changed regularly?

It doesn’t. Some grease passes the filters as vapour and settles in the ducts, so the full system still needs cleaning to TR19.

Does a filter exchange disrupt service?

Not for long, and we can time it to avoid service. The canopy shouldn’t be used without filters, so we swap them in one go.

Do I get a report after the visit?

Yes. It’s the record insurers and inspectors ask to see: a written, dated record with pictures of what we did and anything we couldn’t access.

How long does grease filter exchange take?

The work itself takes anything from a few minutes to an hour or so, depending on the number of filters. Bigger or more complicated systems take longer, and we’ll tell you what to expect.

When something else is needed

We’ll always give you a straight diagnosis, so here’s what grease filter exchange won’t do:

  • Grease deep in the extract system
  • Grease behind the filters that a swap can’t remove
  • A canopy that does not capture the vapour properly

Not sure which it is? You can give us a ring on 0345 646 2711 or email us and we’ll tell you honestly before booking.

What we work on in Brent Park

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

In-house cleaning or a specialist?

Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.

A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
