From my personal experience you do not need visa to travel to Mexico if you intend to stay there for less than 180 days. I visited mexico in February 2017 at which time I was an Indian passport holder with limited leave to remain visa in the UK so rules were the same back then.
However be prepared to show strong evidence of you returning back to either UK or your home country as they do ask a lot of questions to establish your motives and whether or not you will return. A return ticket + a bank statement of UK bank showing good amount of balance would be plus point. Also travel with enough money to show that you can support yourself while you are there as otherwise it will raise their suspicion as to how you will survive your holidays. We travelled in an all inclusive holiday deal with return flight bookings and yet both me and my partner had to face such questions.
