I can see William and Annie, as she is listed, in the electoral register in Lambeth Square in 1930 - 32 and then Hackney Road in 1933 & 1935. She'd have to be at least 21 to be on the register in 1930, which would make her born c1909 or earlier. Her husband is in full Charles William Theodore and b c1909 (his mother Amelia lives with them).
Still doesn't help with a birth - unless she was born in Ireland
