Changing jobs doesn't mean losing your pension, but it does mean making a decision, even if that decision is simply to do nothing. Multiply that decision across a working life with several employers, and it's easy to see how the UK ended up with an estimated £31.1 billion sitting in roughly 3.3 million lost or forgotten pension pots. This guide covers what actually happens when you leave a job, whether consolidating old pensions is a good idea, and one specific type of transfer that comes with a serious warning attached.
For the mechanics of how workplace pensions work day to day, see our workplace pensions explained guide.
The Lost Pensions Problem
According to the Pensions Policy Institute, the average lost pension pot is worth around £9,470, rising higher still for older age groups who've had more time to accumulate forgotten pots from previous jobs. The money isn't gone, pension providers hold it indefinitely and it can be reclaimed at any time, but finding it requires you to actually go looking, and most people don't.
The free government Pension Tracing Service, available at gov.uk/find-pension-contact-details, can help you locate old pensions using just an employer's name, even if you don't remember which provider they used. A Pensions Dashboard, letting anyone see all their pension pots in one place with a single login, is in development, but isn't expected to be available to the public before the 2027/28 financial year, so the tracing service remains the practical option for now.
Your Options When You Leave a Job
You generally have three choices, and none of them is automatically correct for everyone.
Leave it where it is. Your pension stays invested and keeps growing, you simply stop contributing to it and don't add a new employer's contributions either. This is often the simplest option, and sometimes the right one, particularly for older workplace pensions with valuable guarantees attached.
Transfer it into your new employer's scheme. This consolidates things into one active pot going forward, which can make tracking and managing your pension considerably simpler, provided the new scheme accepts transfers and doesn't charge heavily to do so.
Transfer it into a personal pension. Rather than moving it to your new employer's scheme, you can consolidate old pots into a personal pension or SIPP that you control independently of any employer, which can be useful if you change jobs often and want one consistent place for everything. See our private pensions explained guide for how these work, including tax relief without an employer involved.
Should You Consolidate?
For straightforward defined contribution pots with no unusual guarantees attached, consolidating into fewer, larger pensions is often genuinely sensible. It's easier to track, easier to manage the investment strategy consistently, and can sometimes reduce the overall charges you're paying if you're moving from a scheme with high fees into one with lower ones.
It isn't automatically the right move for everyone, though. Checking each pension's specific charges, investment options, and any guarantees before moving it matters more than defaulting to "combine everything," since some older pensions include valuable features, guaranteed annuity rates in particular, that are lost permanently if transferred away.
Worth checking: Before transferring any old pension, check for exit fees or early withdrawal charges, which are more common on older policies than modern ones, and confirm whether the pension includes any guarantees, like a guaranteed annuity rate, that wouldn't carry over to a new scheme.
The Big Warning: Defined Benefit Transfers
If any of your pensions is a defined benefit, or final salary, scheme, the advice here is different, and it's worth taking seriously. Defined benefit pensions promise a guaranteed income for life, and transferring out of one converts that guarantee into a cash sum with no such promise attached, a genuinely significant decision that's gone badly wrong for a meaningful number of people in the past.
By law, if the transfer value of a defined benefit pension is worth more than £30,000, you must receive regulated financial advice before transferring, and the adviser is required by the Financial Conduct Authority to start from the position that keeping your defined benefit pension is usually the right choice. The FCA's own stated position is that most people are best advised not to transfer a defined benefit pension at all. Advisers are also banned from charging fees that depend on whether the transfer actually goes ahead, specifically to remove the incentive to recommend transferring regardless of whether it's genuinely in your interest.
Ask your employer: If you're unsure whether an old pension is defined benefit or defined contribution, your previous employer's HR team or the scheme administrator can confirm this directly. It's worth checking before assuming, since the two types require completely different approaches to any transfer decision.
What About Apps and Platforms?
A number of digital services now specialise in tracing and consolidating pensions on your behalf, typically for a fee taken from the pension itself rather than your bank account. Digital-first providers like PensionBee, Penfold, and Moneybox have built their entire offering around finding and combining old workplace pensions into a single, app-managed pot, while established investment platforms like Hargreaves Lansdown, AJ Bell, and Interactive Investor also accept pension transfers into a self-invested personal pension, a SIPP, typically aimed at people who want more direct control over what they're invested in rather than a managed, app-based approach.
These aren't recommendations, since which suits you depends on your own priorities, simplicity and hands-off management versus lower ongoing charges and more investment choice being the main trade-off between the two styles. They can be a genuinely convenient way to locate scattered pots without doing the legwork yourself, but it's worth comparing what any given service actually charges against doing it directly through the free government tracing service and transferring manually, since the convenience isn't free.
Whichever route you choose, the same underlying checks apply: confirm exit fees, confirm whether any guarantees exist, and treat a defined benefit pension as a case requiring proper advice rather than a quick consolidation.
