if u are thinking of being a ltd company, companies house will not let you have the same name as they have to approve it beforehand
if its for sole trading then you can do just about what you like
as you will only ever be officialy known as ryan ........
that is if memory serves me correct
friend had to go through all this a while back,
there is a company called abacus at 118 hiltingbury road
that will guide you through it all & if you want a "ltd" will set it all up
for you & allow you to use there address an a registered office for about £150.00
or there abouts
