Wow, I thought I would have some good recommendations, then couldn't think of any names so searched strapon in AW and still couldn't pick any that I'd seen, although there are quite a few.
Not sure if you want a domme experience, but most of those will.
Mistress Linda - Beeston
If you're prepared to go further afield I can recommend:
Lexi Ryder - Bradford
Kristina - Huddersfield
Mistress Elizalou - Halifax
Mistress Ella - Huddersfield
Claudia - Halifax (BBW Rom, but decent service)
Even futher
Prestwich, Manchester - Roses Retreat (great VFM) has Martine, who is superb, Libby, Amber
Manchester Chambers Radcliffe
Ones I haven't seen, but I believe are good
Chloe Dominatrix - Leeds Dock
Mistress Ava Dresden - York
Busty Bailey - Bradford/tours inc Skipton
Skyla Blue - Bradford/tours inc Skipton
BlondeDomGirl - read FishyFoo's incredible review
I'll have a think because I really thought I'd know more
