I think you make a very important point, and we had a decarbonisation ministerial task and finish group on Monday, where we were talking about this, because, obviously, we've been concentrating on energy efficiency as our way of tackling fuel poverty, but we also need to look at retrofitting in respect of decarbonisation and how we are going to obviously hit those targets as well.

We will be having new fuel poverty data at the end of 2018 and that will absolutely inform the discussions that we have, particularly with our stakeholders. I'd be very happy to come along to a cross-party group, if you wish me to do so.
