About our grease filter exchange in Potters Bar

Good filters only work when they fit properly. Bent, damaged or missing filters leave gaps and every filter is checked when we swap them. We point out any that need replacing. The work covers baffle filters, wall canopies and restaurants and pubs, and common reasons people get in touch are drips falling from the filters onto equipment and gaps where filters have been removed.

Kitchens in towns like Potters Bar are often in older buildings that were never designed for them, so duct runs can be awkward, with bends, long horizontal sections and too few access panels. Where the duct can’t be reached, new panels can be fitted, and anything left uncleaned is recorded on the report.

Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

Keeping the system healthy

So the system stays in good health:

  • Make sure we can reach the canopy on exchange day
  • Mention it if the kitchen gets busier
  • Do not let the full clean slip because filters are changed
  • Keep every filter in place during service

Your team carries on as normal, without the filter washing. Just keep the canopy clear for the next visit and tell us if service times change.

Clean filters plus regular full cleans keep the system in good health. A maintenance plan that covers both keeps everything on track.

Why it’s worth doing now in Potters Bar

A filter exchange is a few minutes; a choked extract affects a whole service. Few maintenance jobs are as easy and few are as easy to forget. With a fire risk assessment or inspection due, getting the work done first puts you on the front foot.

Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you’re not sure what’s needed, give us a ring on 0345 646 2711 or send us an email for straight advice and a fixed quote.

Multi-site and managed buildings

Records are where multi-site compliance often slips. Every visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.

We regularly work with managing agents. Send the address, what’s needed and how access works, and we will send a fixed quote.

What affects the cost of grease filter exchange

The diagnosis comes before the price. The main factors are:

  • Access, including roofs, risers and ceiling voids
  • What state the system is in
  • Site rules, permits and inductions
  • A single visit or a regular plan

One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before any work starts.

What to send for a quote

We can often survey from pictures. The most useful are:

  • When the site is open and when it’s quiet
  • Where the plant sits or the system leaves the building, such as a roof or outside wall
  • Any previous report or certificate
  • The postcode and the type of business

Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.

Grease filter exchange in Potters Bar: the local picture

Look up Potters Bar on the FSA’s food hygiene register and you will find about 41 cafés, restaurants and staff canteens and about 23 takeaways across Potters Bar and its immediate surroundings (about a mile and a half). Clogged filters slow the airflow, and busy kitchens like these clog them fast. In Potters Bar, food businesses are inspected by environmental health officers from Hertsmere council. 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 Potters Bar 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.

A hospital like Barnet General Hospital, about 3.4 miles south-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day. If you run a café or takeaway near Potters Bar station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits. Volunteers running a hall kitchen near St. Mary's Church, or anywhere in Potters Bar, may not know when the extract was last cleaned, and a grease test settles it.

What happens on the day

There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, while signing off means the written report and photos. Most of the time goes on the work itself, and that takes less than an hour in most kitchens. We arrive in Potters Bar once you’ve closed and leave the site ready for the morning.

  1. We start by noting how many filters you have and what type they are.
  2. We agree a schedule that suits how much the kitchen cooks.
  3. On each visit, the dirty filters come out of the canopy.
  4. Clean, dry filters are fitted in their place, with no gaps left between them.
  5. Anything we notice, such as bent filters or a dirty plenum, is pointed out.

Preparing for the visit

  • Dig out any earlier paperwork for the system
  • Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
  • Make sure someone can let us in and lock up afterwards

School, care home and staff kitchens

Even kitchens with fixed meal times build up grease though typically at a gentler pace.
