What Is Auto-Enrolment and Why It Means Millions of Forgotten Pots

Auto-enrolment is one of the most significant changes to UK pensions in decades. Introduced in 2012, it requires every employer to automatically enrol eligible workers into a workplace pension scheme. The goal was simple: make sure more people save for retirement. And it's worked, over 10 million additional people are now saving into a pension.

But there's an unintended consequence that nobody talks about enough: auto-enrolment has created millions of tiny, forgotten pension pots scattered across the country.

How auto-enrolment works.

If you're aged between 22 and State Pension age, earn more than £10,000 a year, and work in the UK, your employer must automatically enrol you into a pension scheme. Both you and your employer contribute, typically 5% from you and 3% from your employer, totalling 8% of your qualifying earnings.

You can opt out, but most people don't. The beauty of auto-enrolment is that it uses inertia to help people save. You're in unless you actively choose to leave.

The problem: pot proliferation.

Here's where it gets messy. Every time you change jobs, your new employer enrols you into their pension scheme, which is usually a different provider. Your old pot stays behind. After three or four job changes, you have three or four separate pension pots with three or four different providers.

For younger workers who change jobs frequently, this effect is dramatic. Someone who's had six jobs since 2012 could easily have six separate auto-enrolment pension pots. Many of these are relatively small, a few hundred to a few thousand dollars, which makes them easy to forget about.

The scale of the problem.

The Pensions Policy Institute estimates that by 2050, there will be 27 million lost pension pots in the UK. Auto-enrolment is a major driver of this growth. The government is exploring solutions like pension dashboards and pot consolidation, but these are years away from being widely available.

What you can do now.

Don't wait for a government solution. If you've changed jobs since 2012, you almost certainly have multiple pension pots. Track them down, consolidate them, or at least know what you have.
