As many as one in four pensioners in Wales are cutting back on heating and eating, according to research released by Age Cymru.
The charity says that figure is higher than anywhere else in the UK.
Now a 'Let's Talk Money' campaign is being launched to encourage older people to claim the benefits they are entitled to receive.
Age Cymru is concerned that so many pensioners are cutting back on basics such as heating and eating and that this problem seems to be more widespread in Wales than anywhere else in Britain.
It is vital that pensioners are getting all the money they are entitled to receive. However, we know that a third of people who are entitled to Pension Credit - which could boost their income by £1,716 a year - are not claiming it.
