The Irish Family Planning Association says it will start offering abortion care at its clinics in Dublin from the 7th of January.
The group, which has bases in the city centre and Tallaght, says it's dedicated to providing the service after the President signed it into law.
Spokesperson Niall Behan says it's now down to the HSE to make sure women who request a termination don't face any barriers.
"Preparing our abortion service has been the focus of our work since the referendum. We’re ready and we’re dedicated to providing abortion care to women in Ireland for the first time", he said.
IFPA Medical Director, Dr Caitriona Henchion, said the service can only begin as planned "if the medication and pregnancy tests are supplied on time, and the protocols for rhesus testing and the provision of anti-D are finalised".
“Our clinics will be providing early medical abortions up to nine weeks’ gestation. Patients who have their first appointment with us and are between nine and 12 weeks pregnant will need to be referred for hospital care. We cannot arrange those first appointments until we are certain those referral pathways are in place.”
The IFPA says it crisis pregnancy counselling and post-abortion care services will continue.
