Looks a bit big for a wren?
The fledglings often look bigger than the adults at this stage - think that the id is correct, only other likely bird is a juvenile robin.
I think it is a wren. The little flicked tail gives the game away. We have a wren in the garden but I've never been lucmy enough to see a baby one. Young robins are more speckly.
