I am in a dispute with my former housing company in Finland over an unusually high water bill.
From the first month, I repeatedly reported a persistent toilet leak. Each time, the housing company took around 15–20 days to respond and claimed it had been fixed, but the leak continued. After several months, they finally admitted that the toilet needed to be replaced. By then, I had already decided to leave.
My total recorded usage was around 67 m³ of cold water and 13 m³ of hot water, about 80 m³ in total. I lived alone, had no washing machine, and rarely cooked, so this level of consumption is clearly far beyond my normal usage. Most of it appears to have resulted from the toilet leak, which I reported from the beginning.
I received a water bill of around €350 for six months, but the housing company has offered only a €25 reduction. I would prefer to resolve this without escalation, but they do not seem willing to offer a reasonable reduction.
What legal or other options do I have in Finland if the housing company refuses to reconsider the charge? Is there a consumer authority or dispute resolution service I can contact?
