Small red and black beetle for ID please.

Observation - Small red and black beetle for ID please. - UK and Ireland. Description: I thought that this beetle looked a lot like Cantharis rustica (Fourth picture) that I photographed on the same day and fairly close by. This one didn't have the black spot on the pronotum and it was quite a bit smaller.
