Not everyone gets a great bundle of helpful information or advice once being diagnosed on the NHS. I seem to remember that there are not even services in every town so I was lucky to at least receive some help from the Essex service at Southend Hospital. Any benefit I did get however was largely down to my individual Occupational Health Therapist so it could be luck of the draw in terms of whether you are allocated an individual who happens to be somewhat knowledgeable or takes a personal interest in really trying to understand the ME/CFS experience.
The Essex Chronic Fatigue Syndrome Service also has quite an informative page. This at least helped start me on my way to understanding things, before and after diagnosis.
