Jamie Smith-Thompson, managing director of Portafina, said: “Pensions can be confusing, and industry jargon can often mean that people push their planning down the list of priorities.

“These findings not only highlight the pension saving hotspots of the UK, but also the areas where people may lack pension investment knowledge and clear, tailored advice. Those living in areas that have particularly small pension pots could be unaware that their savings are likely to be insufficient when they retire, putting their future lifestyle at risk if they do not have other sources of income.”
