Even if your next job requires you to move somewhere else, you’ll still have had 12-24 months (or however long) of cheap living, and you get to save all that money.

For me at least, between rent, bills, and not having access to the same expensive habits as in a big city (Uber Eats and ease of going out), means that this year I stand to save about £20K compared to the previous year. Even if it was just rent+council tax I’d still be saving about £10K.

That makes a huge difference, especially when the move itself was only about £2K (moving company and a few other bits). Even if I had to move again next year I’d still be coming out ahead.

Obviously it’s not for everyone but the savings are too big to dismiss something like this, in my opinion.

I guess I was considering from a buying perspective, rather than renting.

I agree that if you're not locked in to a well below market rent, then this would definitely make sense.

Or your flexible employer changes its mind on working from home.

Bingo. In the UK contracts almost always state your contracted place of work as <office address>, and WFH is a privilege not a right.
