Common UK retirement planning mistakes and how to avoid them: not checking your State Pension, opting out of workplace pensions, losing old pensions, ignoring fees and inflation, and taking money out unwisely.
Retirement planning can feel distant until it suddenly isn't. Many of the most expensive mistakes are easy to avoid if you spot them early. This guide covers the common ones and what to do instead. It's general information; for personal recommendations, use a regulated financial adviser, and for free guidance on your options from 50, use Pension Wise from MoneyHelper.
1. Not checking your State Pension
From April 2026, the full new State Pension is £241.30 a week (about £12,548 a year). You usually need 35 qualifying years of National Insurance for the full amount, and at least 10 years to get any. Check your forecast on GOV.UK. If you have gaps, you may be able to fill them with voluntary contributions, which can be very good value, or through National Insurance credits, for example for caring or claiming Child Benefit for a child under 12.
State Pension age is rising from 66 to 67 between 2026 and 2028. Check yours, because plans based on the wrong age can leave a gap.
2. Opting out of a workplace pension
Under auto-enrolment, eligible employees are enrolled into a workplace pension, with a minimum total contribution of 8% of qualifying earnings, at least 3% from the employer. Opting out means giving up the employer's money and the tax relief. If your employer offers to match higher contributions, consider taking the full match.
3. Losing track of old pensions
People who change jobs often leave small pots behind. Keep a list of providers and policy numbers, and update your address. The government's Pension Tracing Service can help find lost pensions. Consider whether consolidating pots makes sense, but check for valuable benefits such as guaranteed annuity rates or defined benefit pensions before moving anything.
4. Ignoring fees
Annual charges compound over decades. A difference of 0.5% a year can reduce a pension pot by thousands of pounds over a working life. Check your total charges and compare with alternatives.
5. Forgetting inflation
An income of £20,000 a year sounds comfortable now, but in 25 years at 2.5% inflation it would buy about what £10,800 buys today. Plan in today's money, and use calculators that show "real" values.
6. Investing too cautiously, or too riskily
Holding a long-term pension entirely in cash can mean missing out on growth. Taking too much risk close to retirement can leave you exposed to a crash just before you need the money. Check how your pension is invested and whether it automatically reduces risk as you approach retirement ("lifestyling"), and whether that suits your plans.
7. Taking money out without a plan
- Withdrawals above your 25% tax-free cash are taxed as income. Taking a large lump sum in one year can push you into a higher tax band.
- Once you take taxable income flexibly, the money purchase annual allowance cuts the amount you can pay in with tax relief to £10,000 a year.
- Consider how long your money must last. Many people underestimate life expectancy.
8. Falling for pension scams
Warning signs include cold calls, offers of free pension reviews, promises of high returns, and pressure to transfer quickly. Check firms on the FCA register, and use the FCA's ScamSmart tool. Never transfer to an unregulated scheme.
9. Not planning for later-life costs
Budget for home maintenance, help at home and possible care costs. Consider whether you'll pay off your mortgage before retiring.
