Hi Sunil,
There are standing charges for both. I reckon about 30 Euros every 2 months for electric. I have registered to have an account with Iberdola (https://www.iberdrola.es), and can get my bills online. These have confirmed that there has been no charge for electricity consumed when property was vacant.
I was informed by the water people that the annual charge would be about 50 Euros but not had enough bills to confirm that. So far I have been charged a connection charge (June last year) and one further payment of around 20 Euros.
Dave.
