What version of web3 do I need to use infura to listen to events?

I heard that infura requires web3 v1.0 or higher to subscribe to events, is this still the case?

You do need to use websockets to subscribe to events. See more here including code samples:

Thank you. I have no idea what websockets are (I’m a noob just starting out) but I will try and tackle that page you linked and see where I end up!

By the way, the implication in your answer is that web3 v1 is required for websockets, is this correct?

Infura’s websockets support web3.js 1.0, check out the docs here, https://infura.io/docs/ethereum/wss/introduction, for more info.
