It could be Christel Dee. If you type "Christel Dee" in google and go to her "2009-2019" tweet, there's a photo of a younger her that does bear a striking resemblance to this character.

Although that depends what her hair looked like when she started working for the Doctor Who brand. I've only ever seen her with dark brownish hair or gray dyed when she was working for the brand.
