Should you consolidate your old pensions into one pot?

Three jobs in your twenties, a couple of career breaks, a move you barely remember – and somewhere in the middle of all that, a pension or two got left behind. You're not the only one. There's currently £31 billion sitting in pension pots people have simply lost track of.

Bringing them all into one place sounds like the obvious fix. Sometimes it is. Sometimes it isn't, and rushing to tidy up can cost you more than the mess ever did. Here's how to actually tell the difference.

How many pension pots are you actually sitting on?

Probably more than you think, and collectively, the UK has £31.1 billion of pension money currently lost track of. Research commissioned by the Pensions Policy Institute found 3.3 million pension pots in the UK are lost or inactive, worth £31.1 billion in total, an average of £9,470 each, up 60%, nearly £12 billion, since 2018 (ABI/Pensions Policy Institute, Lost Pensions 2024, October 2024). Much of it comes from ordinary job changes rather than carelessness. A further 12.1 million defined contribution pots are worth under £1,000 and no longer receiving contributions, together worth more than £4 billion, and the number keeps rising as people move employers more often (IFS, Small pension pots, February 2025). None of this means you have done anything wrong. The system was built around staying with one employer for decades, and almost nobody does that any more.

When bringing them together genuinely helps

Consolidating usually makes sense when your old pots are straightforward defined contribution pensions, the fees on at least one are high, and the main thing stopping you checking your retirement savings is that they live in four different logins. One provider, one fee structure and one place to see the total picture is a real benefit, not just tidiness for its own sake. Before moving anything, compare the annual charge on each old pot against where you would move it to, and ask each provider whether there is an exit penalty for leaving.

When it can cost you to combine them

Some older pensions carry a guarantee a modern pot cannot replace, and transferring away usually means losing it for good. Guaranteed annuity rates on 1980s and 1990s policies can pay a retirement income well above today's market rate, and with-profits funds sometimes apply a market value reduction if you leave before a set date, quietly shrinking your pot on the way out.

Defined benefit, or final salary, pensions sit in their own category. MoneyHelper's guidance is blunt about it: most people are better off keeping a defined benefit pension, since it promises a guaranteed income for life rather than a pot you manage yourself. If one you are considering transferring is worth more than £30,000, you are legally required to take regulated financial advice before you can move it.

Why this matters more if your career has not run in a straight line

Women are more likely than men to end up with several small, scattered pension pots, and it is not really about choice. Around half of the pots women accumulate over their working lives are worth less than £5,000, compared with 32% of men's pots, a gap the Institute for Fiscal Studies links directly to part-time work, lower contributions during those years, and moving employer more often (IFS, February 2025). That leaves a part-time or paused career with more small pots to track down than a more linear one, and that is routine admin, not a reflection on anything you did differently.

The rule change that could move some of your pots without asking you

The Pension Schemes Act 2026, which received royal assent in April 2026, sets up a framework for automatically consolidating very small, inactive pots, generally £1,000 or less with no contributions for 12 months or more, into an authorised default consolidator. This will not happen quickly. It is designed to come into force once fewer, larger pension providers, sometimes called megafunds, are established in the market, which is expected to take past 2030, so it is worth finding your own small pots now rather than waiting for the system to do it for you.

From Lucy, co-founder of Welleness

I have three old pensions from jobs I left more than a decade ago, and for years I could not have told you what any of them were worth. One was from a job I did for eighteen months in my twenties, and I only remembered it existed when I needed my National Insurance number for something else entirely.

When I finally tracked all three down, one turned out to have a guarantee attached that was worth more to keep than to move, which I would never have known if I had rushed to tidy everything into one place. It taught me that consolidating is not automatically the sensible choice it sounds like. Sometimes the sensible choice is finding out first, then leaving one exactly where it is.

If you take one thing from this, let it be permission to look properly before you decide anything.

What you can do now

Use the free Pension Tracing Service at gov.uk/find-pension-contact-details to get contact details for any pension you have lost touch with, searching by employer name if you no longer have paperwork.

Before you transfer anything, ask each old provider in writing whether your pot has a guaranteed annuity rate, a with-profits fund, or any other safeguarded benefit attached, since these are often worth more than a lower fee elsewhere.

If any old pension is a defined benefit or final salary scheme worth more than £30,000, know that regulated financial advice is a legal requirement before you can transfer it.

Frequently asked questions

How do I find pension pots I have lost track of?
Use the free Pension Tracing Service at gov.uk/find-pension-contact-details, searching by employer name, then ask the provider for your current pot value directly.

Is it always free to consolidate my pensions?
Usually, for straightforward defined contribution pots with no special features, though some older schemes still charge an exit penalty, so check first.

Will my old pension pots be moved automatically without me doing anything?
Only very small, inactive ones eventually, once the Pension Schemes Act 2026's small pots reforms are fully in force, which is not expected until after 2030.

Should I ever consolidate a defined benefit pension?
Rarely, and only after regulated advice, since most people are better off keeping the guaranteed income it provides.

Here is what one Welleness member said after completing her financial health check.

"If Welleness didn't exist I'd have done absolutely nothing. I feel like this has really helped me sort some stuff out. Having this experience has definitely made me feel like I should just ask the questions, get that advice, get myself into a better position." Brona, Welleness user
