Abortion services at Marie Stopes family planning clinic have been restarted several weeks after they were suspended because of concerns raised by standards watchdog the Care Quality Commission (CQC).
The abortions were halted after an inspection by the CQC highlighted issues over ensuring the woman's best interests and the adequacy of staff training.
Among the services affected were surgical abortions for girls under 18 and for vulnerable women, terminations under general anaesthetic or conscious sedation, and all surgical terminations at the group's Norwich centre.
In Northern Ireland, women under 18 were no longer able to access Marie Stopes' services, and alternative arrangements had to be put in place for women travelling to England to have a termination.
Simon Cooke, chief executive of Marie Stopes International, said at the time services were suspended: "As of today Marie Stopes UK has agreed with the CQC to voluntarily suspend some of its termination of pregnancy services.
"This is to allow Marie Stopes UK to resolve areas of concern in its training and governance procedures.
"We are working urgently with the CQC on these areas and intend to regain full assurance within a few days."
