Well it's doesn't make happy reading but since you asked ..........
For men born before 6 December 1953, the current State Pension age is 65.
For women born after 5 April 1950 but before 6 December 1953, their State Pension age is between 60 and 65.
Women’s State Pension age will increase to 65 between April 2016 and November 2018.
From December 2018 the State Pension age for both men and women will start to increase to reach 66 in October 2020.
These changes affect you if you're a woman born on or after 6 April 1953
or
a man born on or after 6 December 1953
The current law already provides for the State Pension age to increase to 67 between 2034 and 2036 and to 68 between 2044 and 2046
The government has recently announced (on 29 November 2011) that State Pension age should increase to 67 between 2026 and 2028.
But this has not yet passed into law and still needs parliamentary approval.
It's a sure fire thing that State Pension age will continue to increase in line with with increases in life expectancy.
As it stands right now your eligibility for payments is dependant upon the numbers of years you have paid the required NI contributions.
For a full pension it's 30 years, anything less and the pension payment decreases. Of course.
Oh and by the way, don't expect to be able to live in the UK on just a state pension.
Andy, your still lucky if you're a member of the NHS pension.
