Can I self-refer for abortion treatment?

Depending on where you live, you can refer yourself to an abortion treatment with Marie Stopes UK and do not need to go through to your GP. Funding of NHS abortion services differs in various parts of the country, so to find out if you can self-refer for NHS-funded abortion care with us in your part of the country, please call us on 0345 300 8090 (24 hrs).

You would otherwise need to be referred to our specialist service. You can ask your GP to refer you or you can go to your local family planning clinic or genito-urinary medicine (GUM) clinic. You can use the NHS tool to find your nearest sexual health clinic tool

Before an abortion can proceed, two doctors must ensure that the requirements of the Abortion Act are fulfilled, and they must both sign the relevant certificate. This could be in your local surgery, if your area does not qualify for self-referrals or our Marie Stopes Doctors if you self-refer. 

Please note that law states that any doctor with a moral objection doesn't have to certify a woman for an abortion but that they must recommend another doctor who is willing to help.

Find out if you are eligible for self referral

While it's beneficial to talk to your GP about your options, you might not wish to do so. Because funding of NHS abortion services differs in various parts of the country, you will have to get in touch with us to find out if the area you live in qualifies for self-referrals. Whether your GP refers you or you self-refer, Marie Stopes UK can offer you a fast, convenient appointment. 

To find out if you can self-refer for NHS-funded abortion care, please call us on 0345 300 8090.

You can speak to us 24 hours, 7 days a week, 365 days a year. If you'd prefer, you can also email us directly at services@mariestopes.org.uk or request a call back at a time that suits you.
