Energy Efficiency

The hon. Gentleman will know that data sharing is a very difficult issue, to which there is no easy ready answer. I do not underestimate it—any attempt to focus in such a way is in some way problematic, given the sometimes limited tools that we have and the restrictions on sharing data. We are considering that project in the Department, because we realise that data sharing poses real challenges. All I can tell the hon. Gentleman is that we will use our best endeavours and, if he has interesting and innovative ideas on how we can make it effective, we will try to frame them in the regulations that we will table before the House rises. I fully take his point on board; data sharing to ensure that we target the most vulnerable is a challenge.
