Extract fan repair across Bendish

About our extract fan repair in Bendish

The extract fan is what pulls smoke, heat and steam out of the kitchen. Once it turns noisy, sluggish or stops altogether, the kitchen gets hot and smoky very quickly. We find out why and put it right with a repair or a replacement. If you’re dealing with a humming noise from the fan motor and a fan worn beyond sensible repair, we can help.

Rural kitchens often have fans mounted on outside walls or roofs, exposed to the weather. Weather and grease together wear out motors and bearings.

The sign-off is always in writing: a written report, dated and illustrated with photos, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

For landlords and multi-site operators

Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.

Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.

When a fan fails in Bendish

Bendish is about 28 miles from central London, well within the area we cover across London and the South East. Evening, overnight and weekend visits are all possible. Environmental health officers from North Hertfordshire council inspect food businesses in Bendish. Food hygiene rules expect food premises to have suitable and sufficient ventilation. That’s one more reason not to keep cooking with a broken fan.

For school kitchens, at schools like Breachwood Green Junior Mixed and Infant School for example, a planned fan repair in the holidays avoids losing lunches in term time.

How it works

Every visit runs to the same pattern: sheeting and protection first, make the system safe, do the work, clear away and hand over the paperwork. The visit itself takes a few hours for most repairs, longer for a full fan replacement. A few photos of the system help us make the most of a visit to a place like Bendish.

  1. We agree a time to attend, out of hours if needed.
  2. The extract is switched off and the fan opened up.
  3. Bearings, drive, impeller, motor and mounts are inspected.
  4. We explain the options and quote a fixed price.
  5. The fan is repaired or replaced, then checked running.

Common questions in Bendish

Who would carry out a food hygiene inspection at a kitchen in Bendish?

In Bendish, it’s North Hertfordshire council that carries out food hygiene inspections. If the extract fan has failed, it’s worth having the repair booked, and the details to hand, before an officer visits.

Do you work at weekends in Bendish?

Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Bendish needn’t be disturbed. When you call 0345 646 2711 or drop us a line, mention when the site is quiet.

What’s TR19?

TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.

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.

Why is our extract fan so noisy?

There are several possible causes, from a worn bearing to a loose fixing. It’s worth having it diagnosed before the fault gets worse.

Who is responsible for fire safety on the premises?

It depends on the building. Under the Fire Safety Order 2005, it’s the responsible person, which can be the employer, the owner, a landlord, an FM or a managing agent.

Do you offer emergency callouts?

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

Do you cover Bendish?

Yes. We cover Bendish and the rest of Hertfordshire, as part of our work across South East England and London. For a fixed quote, ring 0345 646 2711 or send us an email.

Different parts, different methods

Fan controls

Supply faults are a job for an electrician. We’ll tell you if that’s what we find so you know who to call.

Roof and wall-mounted fans

Many kitchen extract fans sit on a roof or an outside wall. How easy the fan is to reach shapes the job, so we ask about it early.

What affects the cost of extract fan repair

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

  • The number of sites or systems
  • Site rules, permits and inductions
  • The condition of the system
  • Working hours and out-of-hours timing

Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we’ll go through it with you.

Helping us quote

To help us quote quickly, please include:

  • Close-ups of filters, grilles, hatches or access panels
  • The postcode and the type of business
  • Photos showing the whole system and its surroundings
  • The paperwork from the last visit, if you have it

For a fixed quote, ring 0345 646 2711 or drop us a line 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. You will usually have a quote within one working day.

When it’s something else

We’d rather tell you now than book work that won’t help, so here are the limits:

  • Grease throughout the ductwork, which needs a full TR19 clean
  • An extract system that was undersized from the start
  • Faults on the gas side of an interlock system, which need a Gas Safe registered engineer

Not sure which it is? You can ring 0345 646 2711, or email photos and we’ll tell you honestly.

Parts of the system we cover

  • Belts and pulleys
  • Kitchen extract fans
  • Bearings
  • Roof and wall fans
  • Fan housings
  • Fan motors

Keeping the system healthy

Once we’ve finished, these simple steps help:

  • Never run the extract with filters missing
  • Keep the emergency number where staff can see it
  • Make sure the fan is cleaned with the rest of the system
  • Keep the grease filters clean and fitted

Before we leave, the fan is run and checked. You’ll hear what we found and what we did, and anything else we noticed is pointed out.

Noise is usually the first sign of a fan problem. Booking a check at this stage keeps it a planned job instead of a breakdown at the worst moment.

When to call us in Bendish

Any kitchen that cooks for long hours works its fan hard, in Bendish or anywhere else. Belts on a belt-driven fan stretch and wear, so the fan squeals or turns more slowly.

If you notice any of these, it’s worth a diagnosis:

  • A humming noise from the fan motor
  • A worn or slipping fan belt
  • An extract fan that rattles or knocks
  • A fan shaking on its mountings

Kitchens in Bendish can call our 24/7 emergency line whenever an extract fan stops.

Before you book anyone

  • Whether the quote shows VAT
  • What paperwork you get at the end
  • Whether the figure could change on the day
  • When they can work, and whether that is outside your opening hours
