Checked my Collins Bird Guide and I reckon Kestrel, and a lady one at that.
It doesn't seem to have the right colour in it's eyes for sparrowhawk and those markings on its back / wings are classic Kestrel. It seems to have that dowdier appearance so common to many birds of the female persuasion. A male Kestrel has a grey head and bolder markings.
