Large Wall Butterfly? (very tatty looking)

Observation - Large Wall Butterfly? (very tatty looking) - UK and Ireland. Description: looks like it has a chunk ripped from it's wing which doesn't help. I'm no expert on butterflies but as none of the 'usual' butterflies seem to fit the bill, I've looked around for something else and Large Brown might just be it.
