Ms Aoife MacEvilly:

We switched from an opt-out model to an opt-in model because of the new GDPR requirements. Essentially, the opt-out model requires the transmission of data without the customer giving consent in advance. It is a question of whether a matter of critical national priority — I refer not only to the urgency of security of supply but also to the urgency of tackling climate change and the cost crisis — would carry sufficient weight to enable us to make a decision of our own volition or whether legislation would be required. That is a matter we would have to consider, but it is worth considering.
