Grease filter exchange across Old Oak Common

Keeping the system healthy

Results last longer with the right care. Here’s what we suggest:

  • Look out for drips from the canopy
  • Keep the canopy clear for exchange visits
  • Do not refit a filter that’s bent
  • Let us know if your cooking hours increase

Once the clean filters are in, the kitchen can cook straight away. We take the greasy filters with us to be cleaned.

Filter exchange and TR19 cleaning work best together. Setting both up on a schedule means neither slips.

Grease filter exchange in Old Oak Common

Filter exchange sits between full TR19® cleans. Clean filters reduce the grease reaching the ducts though vapour still carries some grease past them. So the canopy, plenum and ducts still need their full TR19 clean. If you have filters that come out of the sink still dirty and missing filters in the filter bank, we can help, from mesh filters, baffle filters and restaurants and pubs onwards.

London kitchens tend to trade late and open early, so extract cleaning in Old Oak Common is usually done overnight, after the last service. Before the clean, we agree loading, parking and roof access with whoever manages the building.

The report is your system’s health record: a dated account with pictures of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

What staff can safely do

Away from the kitchen, the in-house job is mainly checking: 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 don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.

How we price grease filter exchange

The survey tells us what the work involves. We look at:

  • The size of the system
  • Parking and loading at the site
  • When the work can happen, such as evenings, overnight or weekends
  • The number of sites or systems

What you pay reflects the actual work. That is why we survey first, from photos or on site, and the price is agreed before we start.

What we need to know

A few details help us quote accurately. When you get in touch, it helps to send:

  • Wide photos of the system and the area around it
  • Your last certificate, test record or report
  • The site address and the type of premises
  • Where the plant sits or the system leaves the building, such as a roof or outside wall

Getting a quote doesn’t take long. 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.

How the visit works

The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. The work on site takes a few minutes per canopy, longer for a large kitchen with several canopies, and the area is cleaned down before we leave. If your building in Old Oak Common has sign-in rules, permits or key holders, mention them when you book.

  1. We record the number, size and type of your filters.
  2. An exchange schedule is agreed to suit your cooking.
  3. The dirty set is lifted out.
  4. A clean set is fitted and checked for gaps.
  5. The dirty filters leave with us and the next visit is booked.

How to prepare

  • Let us know about parking and loading
  • Plan for cooking equipment or plant to be off before we arrive
  • Make sure someone can let us in and lock up afterwards

Get a fixed quote

The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.

Signs you need grease filter exchange in Old Oak Common

Missing filters are more common than you’d think. Every gap in the filter bank lets grease straight into the plenum and on into the ductwork.

Any of these means the system needs a check-up:

  • Grease collecting in the filter channels
  • Filters left unwashed on busy weeks
  • Grease dripping from the canopy
  • Filters that come out of the sink still dirty

Volunteers running a hall kitchen near Church of Eritrean Orthodox Brent, or anywhere in Old Oak Common, may not know when the extract was last cleaned, and a grease test settles it.

What your quote should include

  • What hours they’ll be on site
  • How VAT is shown on the quote
  • How they set the interval to the next visit
  • Which accreditations they hold, and whether you can check them

Our hiring checklist

How the job changes from site to site

Baffle filters

Baffle filters are a common choice for commercial canopies. They don’t clean themselves, because the grease they collect builds up.

Mesh filters

Layers of mesh catch grease droplets. They clog quickly in a busy kitchen, so they need changing often.

Why act early in Old Oak Common

Once filters are saturated, more grease gets past them. The ductwork then loads up faster, and grease may build up faster than the cleaning interval allows. For a site in Old Oak Common, fitting the work in overnight now is far easier than closing at short notice later.

Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at, and you’ll get one fixed quote.

Look up Old Oak Common on the FSA’s food hygiene register and you will find about 410 restaurants, cafés and works canteens and about 159 takeaways and sandwich shops within about 1.5 miles of central Old Oak Common. Clogged filters slow the airflow, and busy kitchens like these clog them fast. London jobs usually start after the last service, with loading and roof access agreed with the building first. Environmental health officers from Brent council inspect food businesses in Old Oak Common. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A dated certificate in the maintenance file answers the question before it’s asked.

If you run catering at a healthcare site, such as a hospital like Hammersmith Hospital about 0.8 miles south-east, the extract may need cleaning more often than a part-time kitchen.

Common questions in Old Oak Common

Do you do school kitchen extract cleaning in Old Oak Common in the summer holidays?

Yes. The holidays are the usual time for school work. Food Standards Agency records list about 43 schools, colleges and universities with registered kitchens within about a mile and a half of Old Oak Common. Tell us your holiday dates and we’ll book the visit for when the site is empty.

Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Just call us on 0345 646 2711, or send details by email with your opening times and we’ll plan around them.

Do you have insurance?

Yes. Duct Doctor is fully insured, and the details are available on request.

Is TR19 a legal requirement?

No, not in itself. TR19® is the benchmark insurers, fire officers and EHOs check against, and many insurers ask for proof of cleaning to it. The legal duty sits in the Regulatory Reform (Fire Safety) Order 2005 in England and Wales.

How do you protect the area?

Floors and surfaces near the work are sheeted before we start, and waste is contained as we go. Before we leave, we tidy up and clean down.

How long does grease filter exchange take?

It depends on the size of the system, but for a typical site it takes well under an hour for most canopies. We’ll give you a better idea when we quote.

What types of premises do you cover?

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

Do you take the used filters away?

We do. The dirty filters are taken away for cleaning and the clean set stays in the canopy.
