About our grease filter exchange in Northend

Washing filters in the kitchen sink is messy and easily missed on a busy week. With a filter exchange, we bring a clean set and take the dirty one away and the canopy is refilled straight away. If you have filters left unwashed on busy weeks and a greasy plenum behind the filters, we can put it right, from island canopies, restaurants and pubs and mesh filters onwards.

Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. We agree access and timings in advance.

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, and we’ve been trading since 2009.

Northend: your questions answered

Do you cover smaller places like Northend?

Yes. Northend is within the area we cover across London and the South East. A survey first, from photos or a visit, means we arrive with the right kit.

Which fire service covers Northend?

It’s Oxfordshire Fire and Rescue Service, which covers Northend. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.

Do you offer maintenance contracts?

Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.

Does the report say when we need you again?

Yes. Every report includes a recommended date for the next visit, based on what we found and how the system is used.

What paperwork should we keep on file?

Everything that shows the system is looked after: reports, certificates, photos and your own cleaning or check logs. One maintenance log per site keeps it simple.

How much notice do you need?

For planned work, earlier is better, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.

What types of filter do you exchange?

The common types of grease filter: baffle and mesh. Tell us what you have when you call 0345 646 2711 or drop us a line, or we will check on the first visit.

Do you have insurance?

Yes, we’re fully insured. We also hold CHAS and SafeContractor for clients who vet their contractors.

What staff can safely do

In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.

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.

How the visit works

We start by comparing what we find with the survey or your pictures. Anything unexpected is raised with you before we go further. After that, the work takes a few minutes per canopy, longer for a large kitchen with several canopies. A quick note on how to find the site and where to park makes a visit to Northend run smoothly.

  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. The filters are checked for fit before we go.
  5. Anything that needs attention, such as a greasy plenum, is pointed out.

Preparing for the visit

  • Have your last certificate or report to hand
  • Mention any sign-in, permit or induction we need
  • Move anything stored near the system

How the job changes from site to site

The plenum

Heavy grease in the plenum often follows clogged or missing filters or that the next TR19 clean is due.

Busy restaurant and pub kitchens

In a busy kitchen, filter washing is easy to skip. A regular exchange means nobody has to remember.

What affects the cost of grease filter exchange

The price is fixed before any work begins. It takes into account:

  • Any permits to work or inductions
  • How many systems or sites are involved
  • Travel, parking and unloading
  • One-off work versus a regular cycle

Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at and we will price it together.

What to send for a quote

Many jobs can be priced from pictures and some basics. Useful things to send:

  • When the site is open and when it’s quiet
  • Wide photos of the system and the area around it
  • Any previous report or certificate
  • Any symptoms, from odd noises to smells or leaks

To get a fixed quote, give us a ring on 0345 646 2711 or email us and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We normally come back within one working day.

Aftercare tips

Good habits slow the build-up between visits. Our tips:

  • Look out for drips from the canopy
  • Keep filter exchange and TR19 cleaning on the same plan
  • Clean the canopy surfaces regularly
  • Never leave gaps in the filter bank

The canopy looks cleaner and the air moves better straight away. Keep the extract running while you cook so they catch grease as intended.

If cooking has stepped up, the filter schedule should too. Changing the interval early stops grease building up unseen in the ducts.

What happens if it’s left?

Once filters are saturated, more grease gets past them. The ductwork then loads up faster and grease readings can rise between cleans. Out of sight is the usual reason a rural system goes too long without attention.

When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account, and the price is fixed before we start.

When something else is needed

Not every problem is solved by grease filter exchange, and we’ll tell you before any work starts. It won’t put right:

  • Grease already built up in the ductwork, which needs a full TR19 clean
  • Grease behind the filters that a swap can’t remove
  • A canopy too small for the cooking beneath it

Not sure which it is? You can call us on 0345 646 2711 or email us and we will tell you honestly.

Where we work

Grease filter exchange around Northend

Fire safety in Northend falls to Oxfordshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. In Northend, food businesses are inspected by environmental health officers from Buckinghamshire council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A TR19® certificate and photo report after each clean gives you a record to show an inspector.

For kitchens in and around Northend, the clean covers everything from the canopy to the discharge. Stonor Park, about 2.1 miles south, is one of the historic houses near Northend; if you run event catering at a venue like that, cleans can be booked between functions.
