Training in the UK

I'm currently working as a Systems Administrator with 4 years experiance professionally in the IT field. I've found myself a great interest in Computer Forensics, and am looking to progress my career in to it.

As I have no formal Computer Forensics training, what courses are available for me in the UK? Going to University isn't an option so it would need to be self-study or part-time.

I've seen Open University course M889 - Computer Forensics and Investigations, and I think that would be worthwhile. But would that alone allow me to get a job as a Forensic Examiner?

Any thoughts or ideas are welcome!
