If you have only the basic state pension you are eligible for further help, like Credit Support, which also brings other benefits.
Our benefits system is very mean compared to most other countries but nobody is expected to live off £600 per month.
Are you thinking of Pension Credit?
It is a great benefit for those who are eligible, but even those on the basic (old) state pension can only claim it if their savings are below a certain level. Off the top of my head, that level is around £15,000 / £16,000. People have to have under £10,000 of savings to get the full amount, a threshold hasn't risen for quite a long time now.
