Combining pension pots or keeping them separate

If you have built up several pension pots over your working life, you do not have to combine them. You can choose which pensions you want to combine and which you would like to keep separate, and there is no rule that says you must consolidate them all¹. Combining can make a pension easier to keep track of and cheaper to run, but it can also mean giving up guarantees, protected tax-free cash or employer contributions that you cannot get back.

The decision usually comes down to what each pot contains. A defined contribution pot, sometimes called a money purchase pension, is based on what you and your employer paid in and how the investments performed, so its value can go up or down². A pot with special features, such as a guaranteed annuity rate or a right to take more than 25% of it tax-free, is a different matter, because those protections can be lost when you move the money⁴.

Before you decide anything, it is worth finding out what you actually have. The Pensions Policy Institute estimates that 3.3 million pension pots are lost or unclaimed in the UK, worth £31.1 billion, with an average value of £9,470⁵. Tracing those pots first means you are deciding with the full picture rather than a partial one.

You do not have to combine: choose which pots to merge and which to keep

The starting point is that consolidation is optional and selective. You can move one old workplace pot into your current scheme and leave another where it is, because the rules let you choose which pensions to combine and which to keep separate¹. That matters most when one of your pots carries a feature the others do not.

The pots worth thinking hardest about are the ones with protections attached. Defined benefits, such as guaranteed annuity rates or protected tax-free cash, can be lost when you move your pension pots⁴. A guaranteed annuity rate is a promise to convert your pot into an income at a rate that may be far better than anything available today, and it usually only exists inside the scheme that granted it. Protected tax-free cash is a right to take more than the standard 25% as a tax-free lump sum, and it can disappear the moment the money leaves⁹.

There is also the question of where the money sits. Consolidating outside of a workplace scheme may result in losing employer-matched contributions, because an employer is only obliged to pay into its own scheme⁴. If your current employer adds money to your workplace pension, moving that pot elsewhere can mean giving up those contributions.

For most people with a handful of ordinary defined contribution pots, the practical difference between combining and keeping separate is convenience against flexibility. One pot is easier to monitor, easier to nominate a beneficiary for, and easier to draw from later. Several pots give you the option of taking money from one while leaving another invested, and they keep any scheme-specific rights intact. Neither route is automatically better; it depends on what is inside each pot.

How personal pensions build up and what your pot depends on

A personal pension is one you arrange yourself, rather than one your employer sets up for you³. The money you pay in is invested by the pension provider, usually in shares and other investments, and the provider sends you an annual statement telling you how much your fund is worth³. Personal pensions are sometimes called defined contribution or money purchase pensions, and they are available from banks, building societies and life insurance companies³.

What you end up with depends on three things: how much has been paid in, how the fund's investments have performed, and how you decide to take your money³. The value of the pot can increase or decrease depending on factors including investment returns and the contributions made⁶. That is the key difference from a defined benefit pension, where the income is worked out from your salary and length of service rather than from investment performance.

You can save as much as you want in a personal pension, and you get tax relief on what you put in up to the annual allowance¹⁰. Saving in a personal pension does not affect your entitlement to the basic State Pension¹⁰. Some employers offer personal pensions as workplace pensions, in which case the employer usually adds money into the scheme as well³.

Fees and charges: annual management and switching costs

Charges are where combining can either save you money or cost you money, and the two effects can cancel each other out. Personal pensions usually carry an annual management fee, and a switching charge applies if you change funds within the plan¹². Those charges are ongoing, so a cheaper scheme can save money over decades while a more expensive one quietly erodes the pot.

The cost of leaving matters just as much. Some providers charge fees for transferring out, which can cancel out the benefits of consolidation⁹. A pot that looks small and untidy may not be worth moving if the exit fee eats the gain. Stakeholder pensions are the exception: they must allow you to switch to a different pension provider without penalty charges¹³.

Advice, where it is needed, is a separate and much larger cost. Consolidating three pension pots totalling £500,000 and receiving ongoing advice about it cost £27,705 over five years, made up of £8,552 upfront and £19,153 ongoing¹⁴. That figure is for a large pot with an ongoing advice relationship, so it is not typical of a simple transfer, but it shows the scale that advice fees can reach.

The practical test is to compare the total cost of the old arrangement against the total cost of the new one, including any exit fee, any new annual charge and any advice fee, over the years you expect to hold the pension. Where the old scheme is cheaper, combining costs you money rather than saving it.

Finding lost pensions before you decide: around 3.3m pots are lost

You cannot make a sensible decision about combining pots if you do not know how many you have. The Pensions Policy Institute estimates that 3.3 million pension pots are lost or unclaimed in the UK, worth £31.1 billion, with an average value of £9,470⁵. Other estimates put the number at more than three million pots, with an average of almost £9,500 each¹⁵. An earlier estimate valued lost pots at £27 billion¹⁶.

The Pension Tracing Service is the free starting point. You need the name of your previous employer or pension service to get started¹⁷. Tracing services will also ask for your name and National Insurance number, as well as details and dates of your previous employers⁹. If you are tracing a pension belonging to someone who has died, the same service can be used to find details of their personal or workplace pension¹⁸.

If your old employer was taken over or merged, the new employer must provide access to a replacement pension that meets or exceeds the government's standards for workplace pensions, give information about the new scheme, and enrol you automatically if you are eligible and stay in employment¹⁹. That means the trail rarely goes completely cold, even after a takeover.

Your right to transfer out of a previous scheme

You can transfer your UK pension pot to another registered UK pension scheme²⁰. You can usually transfer or consolidate your pensions at any point, unless the scheme rules list restrictions¹. In some cases it is also possible to transfer to a new pension provider after you have started to draw retirement benefits²⁰.

The process has a set order. You check that your current scheme allows transfers out, make sure you will not lose any benefits, decide which scheme to transfer into, check whether you need to pay for financial advice, ask your current provider for a transfer value, and ask the new scheme to start the transfer¹. The transfer value must, by law, be fair to you²¹.

There are limits on what can move. You might not be able to transfer your pension if you have a share of an ex-partner's pension following a divorce, or a scheme with special features or guarantees such as a Guaranteed Minimum Pension²². Where a pension has been shared on divorce, the former partner becomes a credit member of the scheme, their share remains within the scheme and cannot be transferred out, and they cannot add to its value through transfers in or by purchasing additional benefits²³.

What can go wrong when moving a pension

The core risk is simple: you could save money or lose valuable benefits²⁴. Which of those happens depends on what the old scheme offered and what the new one does not.

The losses that come up most often are guarantees and protections. Defined benefits such as guaranteed annuity rates or protected tax-free cash can be lost when you move your pension pots⁴. You may also have to make payments to the new scheme, pay a fee to make the transfer, lose any right you had to take your pension at a certain age, lose any fixed or enhanced protection, or lose any right you had to take a tax-free lump sum of more than 25% of your pension pot²⁰. Each of those is a permanent change.

Employer contributions are another casualty. Consolidating outside of a workplace scheme may result in losing employer-matched contributions⁴. If your employer pays into your current workplace pension, moving that pot to a personal pension can mean those payments stop.

The Financial Ombudsman Service sees the disputes that follow. Common complaints include an adviser not disclosing higher charges, loss of guarantees such as guaranteed annuity rates, market value adjustments on with-profits funds, unsuitable risk checks or investments, and loss of workplace pension benefits²⁵. One case involved a saver whose SIPP charging structure was considerably higher than her previous stakeholder pension plan²⁶. The lesson from those cases is not that transfers are always wrong, but that the charges and the lost features need to be compared before the move, not after.

Minimum pension access age rises from 55 to 57

The age at which you can normally take money from a personal or workplace pension is 55, rising to 57 from April 2028⁷. That change matters to the combining decision because a protected pension age can be lost on transfer. Some current pensions protect the right to take money at 55 beyond that date, and moving the pot can give up that protection²⁷.

If you are planning to combine pots in your early or mid fifties, the access age of each scheme is worth checking before you move anything. A pot that lets you draw at 55 is more flexible than one that does not, and that flexibility has a value even if you do not intend to use it immediately.

Once you can access the money, the usual options apply. You can take up to 25% of your pension as a tax-free lump sum at any time from age 55, rising to 57 from April 2028²⁸. You can also take up to 25% of the value of your pension pot as a tax-free sum and use the rest to provide an income²⁹. If you set up your own pensions, you can use the small pot rules to take up to three of them in one go without triggering the money purchase annual allowance, and there are no limits for employer-set-up pensions²². A whole pension pot worth up to £10,000 can be taken as a lump sum².

Complaints about personal pensions and where to get help

Personal pensions are the most complained-about pension product. In 2024/25 the Financial Ombudsman Service recorded 4,698 new complaints about personal pensions, the highest of any pension product³⁰. In the first quarter of 2025/26 there were 1,122 personal pension complaints, with a 51% uphold rate³¹. In the first quarter of 2026/27 there were 931 personal pension complaints, with 42% upheld³².

If something goes wrong with a personal pension, the Financial Ombudsman Service can look at complaints about group personal pensions³³. Complaints about the administration of personal and occupational pension schemes go to the Pensions Ombudsman³⁴. For a workplace pension, complaints about how the scheme is managed go to MoneyHelper or the Pensions Ombudsman¹⁹. Complaints about your state pension go to the Pension Service instead³⁵. All complaints can be escalated if you're not happy with the response you're provided with in the first instance³⁶. The Pensions Ombudsman's member guidance hub covers how to complain about a pension problem, common pension complaint topics, who can complain to TPO, and what TPO can and cannot do, including overpayments, ill-health pensions, death benefits and incorrect pension information³⁷. Complaints about personal (private) pensions and mis-sold schemes, including SIPPs and Income Drawdown schemes, go to the Financial Ombudsman³⁸.

The Pensions Ombudsman publishes member guidance covering how to complain about a pension problem, common complaint topics, who can complain, and what it can and cannot do³⁶. The topics it covers include overpayments, ill-health pensions, death benefits and incorrect pension information³⁶. Where a scheme has failed, the Pension Protection Fund handles complaints and all complaints can be escalated if you are not happy with the response you are given first³⁷.

Free, impartial help is available before you get to the complaints stage. MoneyHelper offers guidance on making the most of your pension³⁸, and Pension Wise provides free guidance on your options, including taking a whole pot and taking an adjustable income³⁹. If debt is part of the picture, National Debtline and Business Debtline both publish guidance on pension freedoms and debt⁴¹.
