I have moved house. It took 10 days for the information about the electricity supply to come from Energia - Flogas took 2 days for the gas supply information.
The most memorable thing in the Energia communication was the warning about a reconnection fee.
I made a couple of attempts to contact them by phone - just to let them know I had made alternative arrangements: first time it was 8.50 in the morning and they were not open. The second time I waited for a few minutes but eventually hung up.
I will not be rushing to do business with them.
