Hi
On signing - you or your lawyer are given all of the relevant documents for the utility companies ( boletines).
With these documents - you can apply for your elec & gas contracts.You need to provide the boletin, a copy of your passport & bank details for direct debit.
Someone needs to be present at the property for both of these connections.
If you are not going to be on the Coast & this is a problem for you - please let me me know.
Kind Regards
Jean
