The chance of the crack in your wall being caused by subsidence and requiring underpinning and/or rebuild is very slim.
Cracks in walls are the result of some kind of movement causes stress that the bricks cannot sustain. Movement can be caused by a variation in moisture, either in the wall itself or in the ground that supports it, temperature variations, chemical reactions or by replacing load bearing, wooden windows with non-load bearing UPVC windows. Some movement comes and goes with the seasons and other movement is permanent.
