The State Pension is a regular payment from the government most people can claim when they reach State Pension age.
Your State Pension age depends on when you were born.
The amount of State Pension you’ll get depends on how many "qualifying" years of National Insurance payments you have.
This includes National Insurance contributions that you pay when you are working and contributions that are credited to you when you are unable to work.
But according to MoneySavingExpert, pension payments are not being fully accessed by thousands.

MSE says thousands of women have been underpaid for their state pension, reports BirminghamLive.
If you're a married female who hit the age of the state pension before the cut-off in April 2016, you could be owed plenty of cash.
The handy windfall could be owed if they had received less than 60% of their husband's pension - so you may be entitled to 60 per cent of that figure.
After following the advice many people reported receiving lump sums, with the average payout coming in at just under £10,000.
Steve Webb, partner at pensions consultancy LCP said: “It is good news that DWP is checking its records to find married women who have been underpaid.
"I have no doubt that in addition to the millions which have already been refunded, this process will result in tens of millions of pounds being paid over.
"But this record check must be comprehensive rather than narrow.

"As things stand, many groups of women, including widows, divorced women and the over 80s will not get a call from the DWP, so they will have to ring up and ask for their state pension to be checked if they think they are being underpaid.
“It would be far more efficient for DWP to do a comprehensive record check, including alerting women who still need to make a claim for an uplift.
"Without this, this issue will rumble on and on, and women will continue to miss out on the pension that is rightfully theirs."
