You can claim the basic State Pension if you are:
a man born before 6 April 1951
a woman born before 6 April 1953
If you were born later, you will need to claim the new State Pension instead.
To get the basic State Pension you must have paid or been credited with National Insurance contributions.
The most you can currently get is £129.20 per week.
The basic State Pension increases every year by whichever is the highest of the following:
earnings - the average percentage growth in wages (in Great Britain)
prices - the percentage growth in prices in the UK as measured by the Consumer Prices Index (CPI)
Further information on the basic state Pension can be found on GOV.UK's website.
