If the UK did join the eurozone, it would be by choice. All you have to do is promise to join it. Then just sit on your heels. No one will actually make you. Case in point: Poland.
Since the convergence criteria require participation in the ERM, and non-eurozone member states are responsible for deciding when to join ERM, they can ultimately control when they adopt the euro by staying outside the ERM and thus deliberately failing to meet the convergence criteria until they wish to.
The main reason the UK doesn’t want to use the Euro is that the pound is actually more valuable than the Euro so it doesn’t really make a lot of sense, and also because we’re not part of mainland Europe so is not as if people can just drive down the road and suddenly they have to use a different currency, which is what it was like traveling through Europe in the past.
