Just make sure you use sand and cement. You may not know about
Accrington Brick ..it has very tight joins

Which I suppose is why mastic was suggested because it will be easier
to get into the crack between the bricks

You should use sand/cement mortar or better still sand/hydraulic lime
mortar which is probably what was used originally. The pointing of a
brick wall is a sacrificial layer and should be weaker than the brick
(sounds easy in this case) and more porous than the brick (which
mastic isnt) to give a route for water to find its way out

Water will find a way out one way or another and it has done it by
blowing the mastic
