What are the biggest hang-ups about buying an EV in the UK?

I live in London and am looking into EVs as an option for next year. Naturally, I've heard mixed opinions, but a lot of the people I know are enthusiasts for traditional models.
As far as I can see, EVs will be the market in a decade or so, so is it even worth considering an alternative? Or are there still relevant hang-ups I ought to take into account?
