The default rule: the creator owns it
Under section 11(1) of the Copyright, Designs and Patents Act 1988 (CDPA), the person who creates a copyright work is its first owner — for literary, dramatic, musical, and artistic works, as well as software and photographs. When you create a logo, write copy, or build a website as a freelancer, you own the copyright in it by default, unless you have agreed in writing to transfer it.
