How to book your private abortion

At Marie Stopes UK, we understand that the process of booking an appointment for an abortion can be daunting, especially if you have never been through the process before and you have no idea what to expect. We have been providing services for women for over 40 years and are always striving to make this process as smooth as it can be for every woman that comes through our door.

For both medical and surgical treatment options, the process of booking is very similar. You can fill in the online form or call us at any time on 0345 300 1202 (or 0044 1454 457542 from abroad). Your call will be completely confidential. 

What happens after I get in touch with Marie Stopes UK?

Once you get in touch with us, we will offer you access to a consultation which can be done over the phone or face to face in a clinic which is most suitable for you. If English is not your first language, please have someone call our helpline on your behalf. At time of booking we can then arrange to have interpreters who can speak with you by phone or help you during your consultation at the clinic. 

A consultation is a brief medical assessment, which purpose is to assess: 

  • If you are pregnant 
  • How far along you are to assess which abortion methods might be available to you
  • If you have considered all your options in relation to your pregnancy
  • If you would like to speak to one of our counsellors at any point 
  • Find a clinic where you might receive your treatment
  • You will also be asked to confirm whether you are coming to Marie Stopes UK privately or via the NHS

Keeping your details secure

We will then take a few personal details to book your appointment. These details captured will be 100% confidential. To protect your information and keep your details confidential and secure, we will set up a PIN and password for you which you will need to keep safe. We will then be able to confirm your appointment details - date, time and address of the clinic or centre - if you have decided to proceed. We will ask you if you would like a confirmation to be sent to you by text, letter or email. 

Information for Irish women

In Eire, you can have a scan at Reproductive Choices in Dublin to determine how many weeks pregnant you might be. In Northern Ireland, our Belfast Centre can also do this for you.
