In practice though over a decade in power the Tories have rejected a lot of perfectly nice ideas that are against their ideology, which results in a lot of low hanging fruit for a Labour government not stuck with that ideology to just do the obvious things that any Tory minister has been told are a good idea but knows they mustn't actually do for ideological reasons. There are also known bad policies which can be scrapped because a new government doesn't need to pretend they were a good idea, the Tories were able to do some of that because they kept changing leader, but not as much as they'd have liked. This winter can't necessarily be expected to be as mild as last winter, but the French nukes are back online, which is a big boost for all of Western Europe, and there's more wind online in the UK even after just twelve months.
