Hi! I am a current third year student midwife. You have to complete a Bachelor's Degree in Midwifery to become a registered midwife. Many universities have different entry requirements, from A-levels to Access Courses. I would recommend looking at local universities and looking at their entry requirements. You can then e-mail them letting them know your qualifications and then can advise you on how to get on the course. Most people complete an Access course, where distinctions and merits are usually required. In addition to this, you should also try to get some experience in the healthcare field, or any job where you can link the skills to midwifery.
Although I understand the disadvantages of midwifery being a degree, it is also a huge privilege and pretty special thing. At the end of the three years, not only do you hold a degree, but you also are enrolled into a professional register. Not many university students get this at the end of three years, so I don't necessarily see it as a bad thing.
