Thought I was taking a pic of a window gnat but suspect this is a small cranefly ?
Taken today South Coast UK about 7mm body length.

it seems a tipulid. Tipuloid by sure. :D

Looks like a winter gnat, a species of Trichocera (family Trichoceridae). The dark-bodied ones I see most often are T. regalationis and T. saltator, but I don't find them easy to tell apart, especially the females :(

a dorsal view would help a lot! :)
really the antenna is typical for trichoceridae, but not sure.

Thanks for the possible ID :). The only other shot I took was a focus stacked closeup which does show more detail on the antennae - assume this is one of the differences between this family and Tipulidae ?

Well, wing venation and genitalic structures also clearly separate Trichoceridae and Tipulidae or Limoniidae :) You have a winter gnat here and I'd exclude Trichocera (S.) saltator as their females have longer ovipositors. It's also a pity wing venation is not visible, so it's impossible to tell what other species this could be...
