Clearly the Government have a role. My hon. Friend may have seen the green deal adverts that have run in the press. They will continue to run this weekend and the weekend after. We will also be launching a digital campaign. This is a tightly focused, value-for-money campaign, not a huge advertising splurge. The real drive will come from the individual offers. What marks the green deal out as different from previous Government energy efficiency programmes is that there will be huge choice, huge competition and lots of market participants.
