If you are talking about the DClinPsy, it is extremely competitive. The acceptance rate overall is about 18%. You apply through Clearing House and can apply for up to 4 centres. Your experience is good, but be prepared for a tough fight! The application process is brutal, and I've know people who have applied again and again for years and not got on (yet!). I'd start looking at Assistant Psychologist roles and applying for those if they come up in your area. Again, they are very competitive, but you may need to try and get experience in which you are supervised by a Clinical Psychologist in order to improve your chances at getting on the DClinPsy. I'm currently an AP in a drug and alcohol service, so that could be a good place to start looking considering your experience. More funding is going into psychology roles in susbtance misuse, so keep an eye out! And good luck!
