We have paid 121 euros in total for our electricity, for 6 months that we have owned our apartment & the water bills have been 38 euros for 5 months.
During that time it was occupied for about 4 weeks but that did include 10 days over Christmas where we had the electric fire blazing most of the time & then a week in Feb where we frequently used the warm air con.
Our development is fairly new & some units are still unsold. While we were there a few weeks ago, we noticed the workmen employed by the developer, plugging their heavy duty equipment into the socket on our next door neighbours patio.
We always turn our electricity & water off when we leave as we have an outside socket & tap so anyone could use them without our knowledge.
If you are in a new build & these are your first bills, it could be that the builder tapped in to your supply. I know that happened to our neighbour. They moved in & had a huge bill within days.
