Finland’s Competition and Consumer Authority (KKV) and Motiva, the Finnish energy and sustainability solutions expert, are warning consumers about potentially misleading sales practices surrounding home battery systems. Salespeople are reportedly pressuring customers into quick purchasing decisions. A common concern is that contracts for these expensive battery systems, costing thousands of euros, grant complete control of the battery’s usage to a third-party company. This arrangement limits the homeowner’s autonomy over their own energy storage. Authorities are concerned that advertised return on investment expectations are unrealistic and not clearly explained to buyers. Consumers are urged to carefully review contracts and understand the terms of service before investing in these systems. The KKV is actively investigating these sales tactics to protect consumers from unfair practices.
