The process

There are three stages on the day: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and photos. The middle part takes longest, and that takes a few minutes per canopy, longer for a large kitchen with several canopies. We agree a date with you, plan the drive to Birchanger and turn up when the site is quiet.

  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.

Getting ready for the visit

  • Dig out any earlier paperwork for the system
  • Let us know about permits to work or site inductions
  • Clear the space around the work

How we handle grease filter exchange in Birchanger

A clean set of filters is a simple, regular dose of prevention. Between full cleans, it keeps the airflow healthy and takes a messy task off your team. The full TR19 clean then gives the system its clean bill of health. Typical jobs include staff short of time to wash filters and a canopy running with filters missing, on island canopies, wall canopies and restaurants and pubs.

In a small place like Birchanger, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. We agree access and timings in advance.

We are CHAS and SafeContractor accredited, we hold 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.

Birchanger: your questions answered

Can you clean school kitchen extracts in Birchanger during the holidays?

Yes, holiday work suits schools best. Around Birchanger, the Food Standards Agency lists about 15 schools and colleges with registered kitchens within a mile and a half or so. You can call 0345 646 2711 or drop us a line with the dates the site is empty.

Which council inspects kitchens in Birchanger?

Kitchens in Birchanger are inspected by Uttlesford council’s environmental health officers. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.

Do you offer emergency callouts?

Yes, day and night, every day of the year. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.

What is TR19?

It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.

Does a filter exchange disrupt service?

Visits are short, and can be booked outside service times. There’s no wait between removing and refitting.

Which grease filters does the service cover?

The common types of grease filter: baffle and mesh. Mention how many canopies you have when you get in touch, or we’ll check on the first visit.

Which kinds of sites do you work on?

All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.

Do you recommend a next date?

Yes. The recommended date is on the report. BESA’s minimum intervals for kitchen extracts range from 3-monthly for heavy use to 12-monthly for light use, and fire dampers need testing at least once a year.

Birchanger kitchens: local notes

Food Standards Agency records list about 98 cafés, restaurants and staff canteens and about 26 sandwich bars and takeaways within 1.5 miles or so of the middle of Birchanger. Clogged filters slow the airflow, and busy kitchens like these clog them fast. Food hygiene inspections in Birchanger are the job of Uttlesford council’s environmental health team. Extraction counts as kitchen equipment, so its condition can come up on the day. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Fire safety in Birchanger falls to Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.

Term dates shape school work: for a school like Birchwood High School, an extract clean fits neatly into a half-term or summer break. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Herts and Essex Hospital is the nearest hospital to Birchanger, about 1.4 miles south-west.

Signs you need grease filter exchange in Birchanger

Kitchens in Birchanger, as everywhere, find filter washing slips down the list on busy weeks. It only takes a couple of missed weeks for a filter bank to clog.

It’s time to book a visit if you see:

  • Filter washing that keeps being missed
  • Smoke and heat lingering under the hood
  • Missing filters in the filter bank
  • Grease left in baffles after washing

Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Barrington Hall is about 4.1 miles south-east), access may need planning.

Fixed quotes for grease filter exchange in Birchanger

There’s no set price list, because no two systems are the same. The quote depends on:

  • How big the system is
  • Parking and loading at the site
  • Site rules, permits and inductions
  • The condition we find in the survey

No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.

What to send for a quote

What to send for a quote:

  • Close-ups of filters, grilles, hatches or access panels
  • Where the plant sits or the system leaves the building, such as a roof or outside wall
  • Anything you’ve noticed, such as smells, noise, drips or poor airflow
  • Any previous report or certificate

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, you get a fixed price before we start.

Honest limits

Some problems need a different service or another trade:

  • An extract that was undersized from the start
  • Cooking smells reaching neighbours, which need odour control
  • Grease deep in the extract system

If you are not sure, just call 0345 646 2711 or use the quote form and we’ll give you a straight answer.

Parts of the system we cover

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

Aftercare tips

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

  • Keep the extract on whenever the range is in use
  • Make sure we can reach the canopy on exchange day
  • Let us know if your cooking hours increase
  • Wipe the outside of the canopy as part of daily cleaning

The canopy looks cleaner and the air moves better from the moment they’re fitted. Always run the extract during cooking 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 staff can safely do

Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.

Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That is our job.

How the job changes from site to site

Mesh filters

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

Canopy filter housings

Every exchange includes a check of how the filters sit, because gaps let grease through.
