It's estimated that £5 billion goes unclaimed every year, mainly by old people. who don't know they're entitled to it, or are too proud or too scared to claim.
If a person in this country has worked and paid tax and insurance for so long, then they are entitled to whatever benefits they qualify for.
This government is only interested in the figures and not the claimants. I for one, am claiming, and will continue to claim every penny that I'm entitled to.
My advice to anyone who should be claiming benefits, but isn't, is to get to the CAB and have them support and advise you on what the law says you are allowed to claim.
Don't be shy, if you don't ask, you don't get.
Here's a couple of good links that you should find very helpful if considering to make a claim.
