That is plenty of time if everything is on schedule.
Add a delay though and having bags tagged through to a flight you miss creates problems, even though in theory you could change your BA flights on the day for free if you have Plus fares and there is space available.
If I were you I would check the on time performance of the inbound and then decide how much of a gamble it is and whether you want a longer cushion or not.
