As temperatures drop, insurance experts and companies across Europe are issuing warnings regarding potential water damage caused by freezing pipes.

In Germany and Switzerland, the German Insurance Association (GDV) has highlighted that approximately 25,000 frost-related pipe damage cases occur annually, costing roughly 140 million euros. Experts advise homeowners to winterize outdoor lines by shutting off water to outdoor pipes and draining them completely, noting that simply turning off a faucet is insufficient if water remains trapped in connecting pipes.

In Sweden, the insurance company If has warned vacation home owners against turning off heating systems to save on electricity costs. Damage manager Sara Aschan recommends maintaining a base temperature of approximately 15–16 degrees Celsius to ensure heat reaches water pipes, while also suggesting that owners shut off water at the main valve to prevent damage during potential power outages.

Further warnings regarding recreational properties emphasize that owners face risks of extensive flooding if water is left in plumbing, boilers, or tanks. To mitigate these risks, experts suggest shutting off the main water supply and thoroughly draining all pipes and appliances, or installing temperature sensors and water leak detectors. Additionally, insurance companies may reduce or refuse payouts if damage is found to result from neglected maintenance or a failure to follow contractual obligations.
