It's not from the 2014 changes.

From https://commonslibrary.parliament.uk/research-briefings/sn06...:

"Someone who was born British and has no other nationality cannot be deprived of their citizenship in any circumstances."

"Deprivation now affects people born in the UK, not just naturalised citizens"

"Until 2003, however, deprivation was only possible for naturalised citizens."

"The Nationality, Immigration and Asylum Act 2002 extended citizenship deprivation to British-born dual nationals for the first time."
