I live in a small Lancashire town, where the majority of the population are muslim.
Most of the muslim ladies wear hijab. But many are fully covered - niquab (eyes showing) or fully with a veil over the eye slot.
It is definitely more common to see this in the last couple of years. Today dropping DD off at nursery i've seen a driving instrucor with niquab on, young girls walking to the local girls secondary school with face veils tied on, mums in burkas pushing buggies on the school run.
Our local pool has a ladies only session. I have noticed that some of the fully covered ladies are white. Maybe they choose to wear it as they are recently converted (recent convert=very devout?), to avoid it being common knowlege it is a mixed marriage?
More young males in the area are also choosing to wear islamic clothing with long beards that seems less talked about.
I also wonder if it is a status symbol for some young males.
eg in the supermarket I often see young asian lads in western clothes, local accent with a young wife/sister? in tow in niquab or burqa.
