Insurance for flour mills, oil mills and mills with a farm shop in Germany
Flour dust burns like tinder, many mills have stood right on the water for centuries, and a broken roller mill stops all milling. For flour mills, oil mills and mills with a farm shop, fire, flooding and downtime are the big issues, plus liability for flour and oil at the customer's end. This page explains what to cover in Germany and what it costs.
Can I get fire insurance for an old mill by a stream?
Usually yes, but insurers ask detailed questions: construction, age of the wiring, dust extraction, fire detectors and distance to the water decide the premium and whether flooding is included. Well documented maintenance and renovation lower the premium noticeably, and a broker can approach several insurers at once.
What goes wrong in this trade
01
Dust explosion and fire
Fine flour dust, an overheated bearing or a spark in the elevator are enough for an explosion. Old timber floors burn quickly.
02
Flooding
Many mills stand right by a river or mill race. Heavy rain and floods fill the basement, drive and store.
03
Roller mill and drive
If a roller or gearbox breaks, milling stops. Parts for older plants take weeks.
04
Foreign bodies and contaminants
Stones, metal parts or contaminated grain end up in the flour, and bakeries reject whole deliveries.
05
Silo and falls
Work in silos, on platforms and on conveyors is among the most dangerous in the business.
06
Valuable old building
Listed mills are expensive to rebuild; a sum insured that is too low hurts after a fire.
For mills with digital controls, stock management and an online shop.
What it costs: example prices
For mills, fire and buildings insurance makes up most of the premium. Construction, dust protection, location by the water and rebuilding value count more than turnover.

Practical tips from your broker
Have the rebuilding value of the mill assessed; for old and listed buildings it is often far above the purchase price.
Check flooding and heavy rain expressly; mills by the water do not get them automatically.
Document dust extraction, cleaning and bearing maintenance; it lowers the premium and helps after a loss.
Agree an indemnity period in business interruption that matches the time to replace the milling plant, usually 12 to 24 months.
If you supply bakeries, include consequential losses at the customer in product liability, such as destroyed bread.
Check whether water wheel, turbine and weir are covered by the buildings policy.
