I have found this 8mm spider in my home, North London. I've been told it may be a false widow but wanted a second opinion.
Note: The silvery parts in the picture are actually brownish in colour

It does appear to be a young spider, and seems consistent with a young Steatoda of some sort, so "False Widow" sounds OK.
Edit: I just did a quick Google search and pulled up a useful paper (link below) that pretty clearly indicates that this is almost certainly a young Steatoda nobilis, one of the 'False Widows'. See the top left - image A
