As Finlandgirl says. In pari=ticular when talking about private market in cities.
for a studio about 30-35m2, private market:
electricity can be well less than 25euros pm, go down to e10 pm, depends on your usage of oven, TV, washing machine etc etc. that in Helsinki, the prices might be different (higher) in the countryside.
there are several providers, you can compare per price or value based (reneweable energy).

heating:
in flats, municipal heating is usually included. however, in a terraced house for instance, if the heating is not linked to the municipal heating network, it works with electricity and can be pretty expensive.
water:
normal system in the private market is charging per person, it is paid in connection with the rent. however, there is a trend to put water meters into new flats but not yet common.
In student residences sometimes both electricity and water are included. as well as internet..... so depends.
But compared to some other countries such as the UK, those expenses are not too high in Finland.
