Combining Pension Pots: When It Helps and When It Backfires

Change jobs a few times and you will accumulate a scatter of pension pots — a few thousand pounds here, a workplace scheme there, each with its own login you have long forgotten. Consolidating them into one pot is one of the most common pieces of pension admin, and it is genuinely useful more often than not. But the exceptions are expensive, so it is worth knowing both sides.

Why combining often makes sense

• Lower fees. Old workplace schemes — especially pre-2015 ones — can charge 0.75–1%+ a year, while modern schemes and SIPPs commonly run at less than half that. On a £50,000 pot over 20 years, a half-percent fee difference is worth tens of thousands.
• One coherent investment strategy. Five pots means five default funds chosen by five different employers. One pot means one asset allocation you actually chose — see our provider comparison guide.
• Admin that actually gets done. One statement, one beneficiary nomination, one login. Scattered pots are how pensions get lost — there are billions in unclaimed pots, which is why we wrote a step-by-step lost pension guide.
• Simpler retirement. Drawing an income from one pot at retirement is far easier than orchestrating five.

When combining backfires

• Defined benefit (final salary) pensions. These promise a guaranteed income for life and are almost always worth keeping. Transfers over £30,000 legally require regulated financial advice, and that advice usually says no — for good reason.
• Valuable guarantees on old policies. Some older personal pensions carry guaranteed annuity rates (sometimes promising incomes far above anything available today) or protected tax-free cash above 25%. Transferring out destroys these permanently.
• Exit penalties. A minority of older schemes charge to leave. Usually modest, occasionally not — check before, not after.
• Protected early access ages. A few schemes preserve a right to take benefits earlier than the standard minimum age (see taking your pension early); transferring can forfeit it.

How to actually do it

List every pot (old paperwork, the Pension Tracing Service, previous employers' HR). For each, ask the provider three questions: what are the charges, are there any guarantees or protected features, and is there an exit fee? Anything with guarantees goes in the "keep or take advice" pile. For the rest, pick your destination — usually your current workplace scheme (which keeps employer contributions flowing in) or a low-cost SIPP (SIPP vs workplace pension) — and let the receiving provider handle the transfers. It is paperwork-light and typically takes two to six weeks per pot.

Rules and allowances change, and your right decision depends on your own circumstances — for anything that affects your money long-term, it is worth checking the current figures on GOV.UK or speaking to a regulated financial adviser (MoneyHelper offers free, impartial guidance).
