Thanks,

You need to scour the HMRC website for info. I think it's the case that if your country and the UK have a reciprocal tax agreement, then the money isn't taxable in the UK as long as you are paying tax in your home country. I don't know which countries were on this list and which weren't.

However, post covid, the rules may well have changed, as working remotely like this is much more common. It's not fundamentally illegal, and if there is a reciprocal tax agreement it's fine by HMRC - but you should check with them.
