Up to 3m people of working age are planning to downsize from their current home to fund their retirement rather than save into a pension.

That is the worrying finding of a report from insurer Royal London called the Downsizing Delusion, claiming a small but growing proportion of people are choosing not to save for their retirement through a pension, but instead they plan to ‘downsize’ to a smaller property and use the proceeds to fund their later life.

The report shows that, looking across the UK as a whole, the average person downsizing from an average detached house, worth £310,000 according to Rightmove, to an average semi-detached house worth £197,000 and using the proceeds to buy an annuity, would secure an annual income from an annuity plus state pension of £13,700. But the typical UK full-time worker has an annual wage of £27,400. This means their income would slump by half on retirement.

The report also highlights a number of barriers to a ‘downsizing’ strategy such as children still living at home, the mortgage not being paid off, house prices falling and a lack of supply where you want to retire.

Steve Webb, director of policy at Royal London, said: “Hoping to live off the value of your home could be a ‘downsizing delusion’ for millions of people.

“In most of Britain, the amount of money you could free up by trading down at retirement to a smaller property would generate a very modest income.

“Someone who chose to save for later life through their home rather than through a pension could easily see their income halve at retirement.

“If they opt out of workplace pension saving they are also missing out on tax relief on pension contributions and a valuable contribution from their employer.

“Even with today’s record house prices, very few people could fund a retirement by selling up and moving to a smaller property.

“In addition, house prices can be volatile, not least in the light of the recent Brexit vote, and depending on the value of a single asset – your home – to fund your whole retirement is an incredibly risky strategy.”

The report is timely given recent Office for National Statistics figures that forecast a growing number of households owned by the over-65s.
