The figure is the highest in the UK with an average of just over £36,000 owed as they prepare to end their working lives, according to a survey by the Prudential.
It found that, across the UK, one in 12 people planning to collect pensions this year will still be paying off their mortgage. Some 8% of those planning to retire in 2014 said they still have not fully paid off their mortgage and around 10% still have credit card debt.
On average, those who still have some form of mortgage and/or non-mortgage debt owe £24,800, though this is 21% lower than the typical debt in 2013 of £31,200, researchers found.
Wales and the north-west of England were the next most likely areas for retirees to owe money, with 21% of people in both of these areas expecting to retire in debt. Those in debt expect to take four years to clear what they owe.
