New Judge, there is a clear warning here,
http://www.direct.gov.../DoItOnline/DG_189931
"Women born on or after 6 April 1953: men born on or after 6 April 1951
At the present time you can't use the online service to get an estimate of your State Pension if you’re:
• a woman born on or after 6 April 1953
• a man born on or after 6 April 1951
We recommend that you do not enrol with the Government Gateway until the on-line service is again available for you to use.
In the meantime you can get an estimate of the State Pension you may get by using the State Pension profiler or asking for a State Pension statement."
