Scandinavian countries aren't 'proper' socialism, where the workers own the means of production - they're capitalist systems with high public spending and a large social safety net, i.e. social democracy. I'm not sure which one OP was referring to in their initial post.
Regardless, I don't think you can transplant the Nordic model wholesale into the UK and expect it to work in the same way. As a PP said, Nordic countries are very culturally homogeneous, and they have very small populations compared to the UK - Sweden is the biggest with about 10 million people and the others have about 5 million, apart from Iceland which has less than half a million. A much higher proportion of residents live in villages where everyone knows everyone, and even their cities are on the whole much smaller than ours - Stockholm, which is the biggest, has a population of less than 1 million.
There's a far stronger sense of community in the Scandinavian countries than in ours, where we have nearly 70 million people from all different cultural backgrounds, largely living in urban areas where most of us hardly know anyone outside of our own friend circles and maybe immediate neighbours. I'm not saying that's a bad thing; I like living in a place where there's all sorts of different cultural influences, from culinary to musical. But it's harder to form a single cohesive vision for society in a country like the UK, and I think that's what's needed for a Nordic-type model to work - people need to feel that the money they're paying in higher taxes is going to be spent on others who share their values.
In our country it's much easier for people to point at (what they see as) 'themmuns', whether that's families where no-one's worked for generations, fundamentalist Muslim groups, students doing PhDs in gender studies or whatever, and think "I don't want my hard-earned money going to people like THAT". You only have to look at the recent election threads to see how deep the divisions are between the 'condescending London elite who have no idea what life is like for ordinary families' and the 'poor ex-mining communities where everyone's too thick to know what's good for them'. In a climate like this, of course people are going to be resentful of wealth redistribution, if it means 'their' wealth is being redistributed to people they see as having fundamentally different values.
Incidentally I think that's one reason why Scotland is so much more left wing than England as well - a much smaller population, combined with a strong sense of national identity that just doesn't seem to exist in the same way south of the border.
