Workers in some parts of the UK face working the best part of a decade longer than others to maintain their current living standards when they retire, according to a report.

The findings raise the prospect of some people having to “work until they drop” to sustain their current lifestyles.

An average earner who starts saving for a pension aged 22 and makes the minimum statutory contributions would need to work until the age of 77 to get the sort of “gold standard” pension enjoyed by many of their parents’ generation, the research from Royal London found.

This is defined as a total pension, including state pension, equating to two-thirds of that person's income before they retired, and it would include protection against inflation as well as provision for a surviving spouse.

Even to get a “silver standard” pension of around half of pre-retirement income, with inflation protection and provision for a spouse, the same worker would need to work until the age of 71, the report found.

But with wages varying across the country, those in high-income areas need to build up much more private pension to maintain their current living standards than people in lower wage areas.

In several areas of London, including Camden, Wandsworth, Bromley, and Richmond upon Thames, people may need to work until their 80th birthday to achieve their current living standards in retirement, the report found.

  In Westminster, someone may need to work until the age of 81 to reach the gold standard – while in Boston, Lincolnshire, they would need to work until the age of around 73 – a gap of eight years.

In Scotland, a worker would be aged 77 by the time they achieved their retirement gold standard, while in Wales and Northern Ireland they would be 76.

Former pensions minister Steve Webb, who is now director of policy at Royal London, said: “It is great news that millions more workers are being enrolled into workplace pensions, but the amounts going in are simply not enough to give people the kind of retirement they would want for themselves, and certainly not the sort of pensions that many of those retiring now are enjoying.

“Even in lower wage areas people face working into their early seventies to get a comfortable retirement.  In higher wage areas, the state pension makes a much smaller contribution so workers in those areas face working well into their seventies.

“The best antidote to having to work well beyond normal retirement ages is to start saving early and to increase pension saving.

“A good tip is to review your pension saving when you get a pay rise as you are less likely to miss money you have never had.  Increasing contributions when your pay goes up is the best way to avoid having to work until you drop.”
