Why so many of us end up with a trail of old pots

If you have changed jobs more than once, the chances are you have left a pension behind. Auto-enrolment means most employees have been building up retirement savings since 2012, and every move to a new employer usually starts a fresh scheme. Ten or fifteen years later, it is easy to end up with four or five pots of £2,000 to £30,000 scattered across different providers, each sending a statement to an address you left years ago.

Consolidating those pots into one place can make life much simpler. It can also be the wrong move entirely. The trick is to work out which of your pensions are worth keeping exactly where they are.

The genuine advantages of bringing pots together

There is nothing glamorous about tidying up old pensions, but the practical gains are real:

• One statement, one login. You can see your total retirement savings at a glance rather than piecing them together from a folder of paper.
• Charges become visible. It is far easier to spot an expensive old scheme when it sits alongside a cheaper one in the same dashboard.
• Lower costs on larger balances. Many providers scale their platform fees down as your pot grows, so a combined £80,000 may cost less in percentage terms than four separate £20,000 pots.
• Simpler beneficiary nominations. You need an up-to-date expression of wish form for every scheme. Miss one and your family may face unnecessary delay.
• Easier drawdown later. Taking an income from one provider is much less admin than juggling six.

For straightforward defined contribution pots with similar charges, consolidation is often a sensible bit of housekeeping.

What you could lose — the crucial checks

This is where caution pays. Some pensions carry benefits that cannot be replaced once they are gone.

• Defined benefit or final salary benefits. These promise a guaranteed, usually inflation-linked income for life, often with a spouse's pension attached. Transfer values above £30,000 legally require advice from a regulated adviser, and in the overwhelming majority of cases staying put is the right answer.
• Guaranteed annuity rates. Some older personal pensions promise a conversion rate on retirement that is far better than anything available today. That guarantee is tied to the scheme and disappears on transfer.
• Protected tax-free cash. A few legacy schemes allow more than the standard 25% of your pot to be taken tax-free. Move the money and you usually revert to 25%.
• Protected pension age. Some pots can be accessed earlier than the normal minimum pension age, which rises to 57 in 2028.
• With-profits funds and exit penalties. Older plans may apply a market value reduction or a exit charge if you leave at the wrong moment.

Before anything moves, ask the receiving scheme and the ceding scheme, in writing, whether any guarantees, protected cash or penalties apply.

Compare charges honestly, and watch the exit fees

Charges come in layers: an annual management charge, a platform fee, the ongoing charge of the funds you hold, and dealing or transaction costs. Add them up for both the old scheme and the new one. A flat £100 annual fee is only 0.2% on a £50,000 pot, but a painful 2% on a £5,000 one.

Exit penalties are the sting in the tail. Some personal pensions sold in the 1990s still carry charges of 5% or more to leave. Run the numbers over the years you expect to hold the pension, not just for one year. Moving a £40,000 pot from a 0.9% total cost to 0.5% saves about £160 a year, which compounds into a meaningful sum over two decades.

Also allow for time out of the market. Transfers normally take between two and eight weeks, and occasionally much longer. Finally, treat any unsolicited call, text or email about your pension as a red flag. Cold calling about pensions is illegal in the UK, and no legitimate provider will pressure you to sign anything quickly.

A practical order of operations

• Use the free government pension tracing service to find schemes you have lost track of.
• Gather every statement and note the scheme type, total charge, exit penalty and any guarantees.
• Decide which pots you want to move and leave the special ones untouched.
• Ask the receiving provider for a full written breakdown of its charges and investment options.
• Ask the old scheme for a current transfer value and confirmation of any protected benefits.
• Consider a partial transfer if you want to keep a foothold in a scheme with useful features.
• Keep every piece of paperwork. A transfer cannot be reversed.

When leaving things alone is the better answer

Sometimes the tidiest option is no move at all. Final salary schemes, pots with guaranteed annuity rates, protected tax-free cash and protected pension ages should generally stay where they are, even if that means running two or three pensions in retirement. You can still consolidate the plain, expensive, unremarkable pots around them.

Very small pots deserve their own thought. Since April 2024, pots worth under £10,000 can usually be taken as a lump sum, with 25% tax-free and the rest taxed at your marginal rate. It sounds tempting, but doing so triggers the Money Purchase Annual Allowance, cutting future pension contributions to £10,000 a year. If you are still saving seriously, that is a heavy price for clearing a small pot.

Take your time, ask questions in writing, and use free impartial guidance if you are unsure. A few hours of checking now can protect benefits worth tens of thousands of pounds later.
