In the UK a 7 is a 7 men's or women's. Men's will just be a bit wider.
Generally men's shoe size are around a size to two half sizes larger than women's shoes. A men's size 6.5 is equivalent to a women's size 8.
The general rule is to take the men's size and add two to get the women's shoe size. That would mean that a men's size 6 is a women's size 8.

There is a 1 1/12 size difference between men's and women's shoes. For example a mens size 6 is a women's size 7 1/2.
