Millions of workers are heading towards retirement with financial gaps that could cost them thousands, as many are making critical errors in their pension planning. From relying too much on the State Pension to withdrawing savings inefficiently, these mistakes are quietly draining retirement funds and leaving people financially vulnerable in later life.

With life expectancy rising and inflation increasing the cost of living, experts say that failing to plan properly could mean running out of money sooner than expected. 

Financial institutions warn that UK retirees are facing shortfalls—but these mistakes can be avoided with the right strategy.

1. Overestimating the State Pension

For many retirees, the State Pension is their main source of income. However, the maximum new State Pension in 2024 is £221.20 per week (£11,502 per year)—far below the amount most retirees need to cover everyday expenses.

The Office for National Statistics (ONS) reports that the average UK household spends over £28,000 per year. This means that even those who qualify for the full State Pension could face an annual shortfall of nearly £17,000.

How to fix it

Financial experts recommend supplementing the State Pension with a workplace pension, private savings, or investments. Checking for gaps in National Insurance contributions can also help maximise the amount received.

2.  Not Saving Enough (Or Starting Too Late)

Workers are not saving enough for retirement, with nearly half of them feeling behind on their pension contributions, according to a recent Bankrate study. Many assume that workplace pensions will be sufficient, but with rising costs and longer life expectancies, a lack of savings could force a lower standard of living in retirement.

How to fix it

Pension advisors recommend contributing at least 12–15% of annual income towards retirement savings. Employees should also maximise employer pension contributions, while the self-employed should set up private pensions with tax relief of up to 45% for higher earners.

3. Ignoring the High Costs of Healthcare and Long-Term Care

While the NHS provides free healthcare, long-term care isn’t covered for most retirees. The average cost of a UK care home is over £50,000 per year, with some high-end facilities charging even more. Without proper financial planning, many retirees are forced to sell their homes or deplete their savings to cover these costs.

How to fix it

Experts suggest considering long-term care insurance or setting aside a dedicated savings fund for care expenses. Some retirees may also benefit from using a Lifetime ISA (LISA), which offers tax-free withdrawals for healthcare expenses.

4. Failing to Account for Inflation

Inflation is eating into retirement savings, making it harder for pensions to last. According to the Bank of England, inflation has hovered around 2–4% annually, meaning that £50,000 today could be worth just £36,800 in 15 years. Many pension plans don’t automatically adjust for inflation, leaving retirees with less purchasing power over time.

How to fix it

Financial advisors recommend investing in inflation-protected assets, such as stocks, real estate, and index-linked gilts. Pensioners should also consider index-linked pension funds, which adjust payments based on inflation.

5. Taking Large Pension Withdrawals Too Early

From age 55 (rising to 57 in 2028), people can begin withdrawing money from their pensions. However, taking too much too soon can result in significant tax bills and depleted savings.

For example, any pension withdrawals above the 25% tax-free lump sum are taxed as regular income. This means a large withdrawal in one year could push retirees into a higher tax bracket, forcing them to pay thousands more in taxes.

How to fix it

Experts suggest following the 4% withdrawal rule, which aims to make savings last 30+ years. Additionally, drawing from ISAs first before pensions can help minimise tax liabilities.

6. Losing Thousands to High Pension Fees

Pension holders often don’t realise how much they are paying in fees, which can drain thousands from their retirement funds over time. A 1.5% annual fee on a £200,000 pension pot could cost over £60,000 in lost savings over 20 years.

How to fix it

To reduce costs, retirees should compare pension providers and consider consolidating old pensions into low-fee investment funds. Low-cost index funds and ETFs offer better returns compared to high-fee managed funds.

7. Not Using a Tax-Efficient Withdrawal Strategy

Withdrawing from a pension without a proper tax plan can lead to higher-than-necessary tax bills. Many retirees take large lump sums instead of spreading withdrawals over multiple years, which pushes them into higher tax brackets.

How to fix it: 

The most tax-efficient strategy involves withdrawing from ISAs first (which are tax-free), followed by smaller pension withdrawals to stay within lower tax bands. A drawdown pension can also help spread income while reducing tax liabilities.

8. Neglecting to Update Wills and Beneficiaries

Many retirees fail to update their estate plans, leaving their assets exposed to inheritance tax (IHT) and legal disputes. The current inheritance tax threshold is £325,000, meaning that any assets above this amount are taxed at 40%.

How to fix it: 

Financial planners advise reviewing wills, trusts, and pension beneficiaries regularly. Setting up a trust can help reduce inheritance tax liability, ensuring that more money stays within the family.

9. Not Maximising Workplace Pension Contributions

Thousands of UK employees miss out on free money by not contributing enough to their workplace pensions to get the full employer match. Over time, this could mean losing out on tens of thousands of pounds in additional retirement savings.

How to fix it: 

Employees should increase their pension contributions to at least match their employer’s maximum contribution level. Higher earners can also benefit from salary sacrifice schemes, which offer tax savings while boosting pension contributions.

Key Takeaway

Avoiding these mistakes can make a significant difference in financial security during retirement. Small, proactive steps—such as optimising savings, reducing fees, and planning tax-efficient withdrawals—can lead to a more comfortable and worry-free future.
