Energy Bill [Lords]

It is certainly the case that hydrogen comes with complications when it comes to home heating, which is why we have a couple of different trials ongoing to understand some of the impacts. We will know more once those trials have been carried out. However, the hon. Lady asked specifically about a levy, so I should point out that the Bill will not itself introduce a levy. She is right that we need to see the results of trials before we understand how that should operate, so we will wait a little while.
