How does the statute of limitations for bills change?

For bills due after 01 March 2018 for electricity supplies and 1 January 2019 for gas supplies, in cases of billing delays of more than two years, customers can plead the statute of limitations and only pay the amounts billed in relation to consumption in the last two years.

As clarified by ARERA - Autorità di Regolazione per Energia Reti e Ambiente (Regulatory Authority for Energy, Networks and the Environment) - the statute of limitations request applies to all fees in the bill, and therefore to both the fixed parts (including the power fee) and the variable ones, and can be submitted by sending the form attached to the bill or downloadable from the Statute of limitations form.
