How to Choose the Best Retirement Planner in the UK

See if you are on track for retirement with the right tools

Most People Do Not Know If They Are On Track

Half of UK adults have not checked whether their retirement savings are on track. Of those who have checked, many are surprised by what they find. A retirement planner is not about predicting the future. It is about knowing where you stand so you can make better decisions now.

Understanding UK Retirement Income Sources

Before choosing a retirement planner, it helps to understand what makes up UK retirement income. Most people will receive income from three sources.

1. State Pension

The full new state pension is currently £10,000 per year. To receive the full amount, you need 35 years of National Insurance contributions.

2. Workplace Pension

Through auto-enrolment, most employees are automatically enrolled into a workplace pension. Your employer typically matches contributions up to a certain level. The average workplace pension at retirement is around £100,000-£150,000.

3. Personal Savings

ISAs, personal pensions (SIPPs), and other savings make up the third pillar. ISAs are particularly valuable in retirement because withdrawals are tax-free.

What a Good UK Retirement Planner Should Do

Not all retirement planners are equal. Some are basic calculators that give you a rough estimate. Others are comprehensive tools that model your specific situation. Here is what to look for.

1

Calculate Your Retirement Gap

A good planner shows you not just what you have saved, but what gap exists between your projected income and the retirement lifestyle you want. This gap is the number that matters.

2

Project Wealth Over 30+ Years

Retirement planning is long-term. Your planner should show projections over 30 or more years, accounting for inflation, investment returns, and changing expenses at different life stages.

3

Model Different Withdrawal Rates

Different withdrawal strategies carry different risks. A good planner shows you how long your money lasts under different scenarios, from conservative 3% to more aggressive 5% annual withdrawals.

4

Include UK-Specific Tax Rules

UK retirement planning has unique tax advantages: ISA allowances, pension tax relief, and the pension commencement lump sum. A UK-focused planner should account for all of these.

Common Mistakes UK Retirees Make

1

Relying Only on Auto-Enrolment

Auto-enrolment contributions are a minimum, not a target. The average auto-enrolment contribution of 8% is unlikely to deliver the retirement most people want. Supplementing with additional contributions is usually necessary.

2

Not Accounting for Inflation

£100,000 today is not worth £100,000 in 20 years after inflation. Many people underestimate how much they need because they do not factor in the rising cost of living over a 20-30 year retirement.

3

Ignoring the Gender Pension Gap

Women in the UK have on average 35% less pension savings than men at retirement. Career breaks, part-time work, and the gender pay gap all contribute. A good retirement planner should help you see and address your specific gap.
