Spain's CNMC tightens consumer consent rules for electricity sales and outlines new gas network remuneration plan

The Spanish regulator Comisión Nacional de los Mercados y la Competencia (CNMC) has reminded electricity retailers that they may not place commercial or contract‑signing calls to consumers without an explicit, informed request. The regulator stresses that consent must be a direct, voluntary action by the consumer, without intermediaries or incentives, and that identity verification must use official documents such as a DNI or passport. Generic consent clauses on third‑party platforms are deemed non‑compliant, and any unilateral contract changes are prohibited for fixed‑price electricity deals.

Separately, the CNMC released a draft circular setting out the remuneration methodology for gas network operators for the 2027‑2032 period. The proposal aims to ensure cost‑effective, transparent and non‑discriminatory compensation while supporting industrial competitiveness and the integration of renewable gases, notably biometane, to aid Spain’s decarbonisation efforts. The framework balances supply security, economic efficiency and environmental sustainability for both industrial and residential gas users.
