Electricity Industry (Customer Contracts) Regulations 2005

Without limiting regulation 15(1), a non‑standard contract (other than a fixed term contract) must authorise the customer to terminate the contract at any time by giving notice to the retailer not less than 5 days before the day on which the customer wants the contract to end.

A fixed term contract must authorise the customer to terminate the contract at any time by giving notice to the retailer not less than 20 days before the day on which the customer wants the contract to end.

A fixed term contract must specify any amount payable by the customer, by way of penalty, in the event that the customer terminates the contract before the expiry of the term of the contract.
