Standard design for a UK house uses bricks (and an interior cinder block lining) to bear all loads unless the design calls for a very narrow pillar. Even where a timber frame bearing roof and floor loads exists so wall bricks just "fill space", they have to be sufficiently performant under compression to support the weight of brick courses above them.
