Black and orange butterfly - but which one?

Observation - Black and orange butterfly - but which one? - UK and Ireland. Description: Every time I got near to photograph this, it closed its wings or flew away! From a distance it looked just black and orange on the upper wings, there may have been some white but I really couldn't tell for sure.
