What is a Pension Annuity?

A pension annuity converts your pension savings into a guaranteed regular income for life. When you retire, you can use your pension pot to purchase an annuity from an insurance provider, which then pays you a fixed amount at regular intervals until you pass away. This provides financial security and certainty throughout retirement, protecting you from the risk of outliving your savings.

In the UK, you can typically access your pension pot from age 55 (rising to 57 in 2028). You have the option to take up to 25% of your pension pot as a tax-free lump sum, with the remainder used to purchase the annuity. The income you receive is subject to income tax at your marginal rate.

Key Advantage: Annuities provide lifetime guaranteed income, eliminating longevity risk and market volatility concerns. Once purchased, your income is locked in regardless of economic conditions.

Annuity Rates Comparison Table

Current estimated annuity rates vary based on age, pension pot size, and selected options. The table below shows approximate annual income for different scenarios:

Age £50,000 Pot £100,000 Pot £200,000 Pot £500,000 Pot
55 £2,100 £4,200 £8,400 £21,000
60 £2,350 £4,700 £9,400 £23,500
65 £2,700 £5,400 £10,800 £27,000
70 £3,200 £6,400 £12,800 £32,000
75 £3,900 £7,800 £15,600 £39,000

Rates shown are estimates for single life, level annuities with 10-year guarantee after taking 25% tax-free lump sum. Actual rates vary by provider and market conditions.

Types of Annuity Options

Single Life Annuity

Provides the highest income but payments cease upon your death. Suitable for individuals without dependents or those with alternative provision for their spouse.

Joint Life Annuity

Continues paying income to your spouse or partner after your death. You can choose the percentage they receive (typically 50%, 67%, or 100%). Initial income is lower than single life.

Level Annuity

Pays the same amount throughout your life. Offers the highest starting income but purchasing power decreases with inflation over time.

Escalating Annuity

Income increases annually by a fixed percentage or in line with inflation (RPI/CPI). Starting income is lower but maintains purchasing power over time.

Enhanced Annuity

Offers higher rates if you have certain medical conditions or lifestyle factors that may reduce life expectancy. Can increase income by 10-40% compared to standard rates.

Guaranteed Period

Ensures payments continue for a minimum period (typically 5-10 years) even if you die early. Beneficiaries receive remaining payments as a lump sum or continued income.

Enhanced Annuity Eligibility

Enhanced annuities can significantly boost your retirement income if you qualify. Providers offer better rates based on factors that may reduce life expectancy:

Medical Conditions

  • Heart conditions: Heart attack, angina, heart bypass, high blood pressure
  • Cancer: Most types, including in remission
  • Diabetes: Type 1 or Type 2, especially with complications
  • Respiratory issues: Chronic asthma, COPD, emphysema
  • Kidney disease: Chronic kidney disease or kidney failure
  • Neurological conditions: Stroke, Parkinson’s disease, multiple sclerosis
  • Other conditions: High cholesterol, liver disease, rheumatoid arthritis

Lifestyle Factors

  • Smoking: Current or former heavy smokers often qualify
  • Weight: Being significantly overweight (BMI over 30)
  • Occupation: Certain high-risk occupations may qualify
  • Postcode: Areas with lower life expectancy may receive better rates
Important: Always declare all health conditions when applying for an annuity. Enhanced rates can increase your income by £1,000-£5,000 annually on a £100,000 pot, potentially adding tens of thousands to your lifetime income.

How Annuity Income is Calculated

Annuity providers calculate your income based on several factors:

Annual Annuity Income = (Pension Pot × Annuity Rate) ÷ 100

The annuity rate depends on:
  • Your age (older age = higher rate)
  • Current interest rates and gilt yields
  • Life expectancy statistics
  • Selected options (joint life, escalation, guarantees)
  • Health conditions (for enhanced annuities)

Calculation Example

Scenario: 65-year-old with £100,000 pension pot, taking 25% tax-free lump sum

  1. Tax-free lump sum: £100,000 × 25% = £25,000
  2. Remaining pot for annuity: £100,000 – £25,000 = £75,000
  3. Annuity rate at age 65: Approximately 7.2% (varies by provider)
  4. Annual income: £75,000 × 7.2% = £5,400
  5. Monthly income: £5,400 ÷ 12 = £450

Adding a joint life provision might reduce the rate to 6.4%, giving £4,800 annually (£400 monthly). Choosing 3% escalation might reduce it further to 5.0%, starting at £3,750 annually but increasing each year.

Annuity vs Alternative Retirement Options

Feature Annuity Pension Drawdown Cash Withdrawal
Guaranteed lifetime income ✓ Yes ✗ No ✗ No
Protection from market risk ✓ Yes ✗ No N/A
Flexible withdrawals ✗ No ✓ Yes ✓ Yes
Potential for growth ✗ No ✓ Yes ✗ No
Inheritance for beneficiaries Limited ✓ Yes ✓ Yes
Income certainty High Variable None
Risk of outliving savings None Possible High
Consideration: Many retirees combine approaches, using part of their pension for an annuity (covering essential expenses) and keeping the remainder in drawdown for flexibility and potential growth.

When Should You Buy an Annuity?

Timing your annuity purchase can significantly impact your lifetime income. Consider these factors:

Advantages of Waiting

  • Higher rates with age: Annuity rates increase as you get older, potentially by 0.3-0.5% per year
  • Interest rate environment: Current higher interest rates mean better annuity rates than in previous years
  • Health deterioration: Developing health conditions may qualify you for enhanced rates

Advantages of Buying Earlier

  • Longer guarantee period: More total income over your lifetime if you live a long time
  • Income security: Immediate protection from market volatility and longevity risk
  • Peace of mind: Knowing your essential expenses are covered throughout retirement
Current Market Context (2025): Annuity rates have improved significantly compared to 2020-2022, with gilt yields at higher levels. A £100,000 pot at age 65 might generate £5,400-£6,000 annually, compared to £3,500-£4,000 in 2021.

Shopping Around for the Best Annuity Rate

Annuity rates vary significantly between providers. Shopping around could increase your income by 15-30% compared to accepting your existing pension provider’s rate.

Steps to Get the Best Rate

  1. Use comparison services: MoneyHelper and independent brokers can compare rates from all providers
  2. Declare all health conditions: Even minor conditions might qualify you for enhanced rates
  3. Consider your options carefully: Adding features like joint life reduces income but provides protection
  4. Check provider ratings: Choose financially strong insurers rated A or above
  5. Get multiple quotes: Rates can differ by £500+ annually for the same pension pot
Important: Once you purchase an annuity, you cannot change your mind. The decision is irreversible, so take time to compare options and consider seeking financial advice, especially for pots over £100,000.

Taxation of Annuity Income

Your annuity income is subject to income tax, but there are important considerations:

  • Tax-free lump sum: The first 25% of your pension pot (up to the Lump Sum Allowance) is tax-free
  • Remaining income: Annuity payments are taxed as earned income at your marginal rate (20%, 40%, or 45%)
  • Personal allowance: The first £12,570 of total income (2025/26) is tax-free
  • PAYE deduction: Tax is deducted at source by the annuity provider
  • State pension interaction: Annuity income plus state pension determines your tax band

Tax Example

Annual annuity income: £15,000
State pension: £11,500
Total income: £26,500

Tax calculation:
Personal allowance: £12,570 (tax-free)
Taxable income: £26,500 – £12,570 = £13,930
Tax at 20%: £13,930 × 20% = £2,786
Net income: £26,500 – £2,786 = £23,714

Common Questions About Annuities

What happens to my annuity when I die?

This depends on the options you selected. With a single life annuity and no guarantee, payments stop immediately. With a guarantee period, payments continue to beneficiaries for the remainder of the guarantee. Joint life annuities continue paying the agreed percentage to your spouse.

Can I change my annuity after purchase?

No. Once purchased, an annuity cannot be changed, cancelled, or sold. This is why it’s crucial to compare rates, consider all options, and potentially seek financial advice before buying.

Do I have to buy an annuity from my pension provider?

Absolutely not. You have the “open market option” to shop around and buy from any provider. This is highly recommended as rates vary significantly between companies.

How much annuity income do I need?

Calculate your essential expenses (housing, utilities, food, healthcare) and aim to cover these with guaranteed income from annuities and state pension. Additional income from drawdown can fund discretionary spending.

What if annuity rates improve after I buy?

You cannot switch to better rates once purchased. However, you can buy multiple annuities over time, a strategy called “annuity laddering,” which allows you to benefit from future rate changes with remaining pension funds.

Are annuities protected if the provider fails?

Yes. UK annuities are covered by the Financial Services Compensation Scheme (FSCS), which protects 100% of your annuity income if a provider becomes insolvent.

Can I buy an annuity with other savings, not just a pension?

Yes. You can purchase a “purchased life annuity” with non-pension savings. However, the tax treatment differs, and only part of each payment is taxable, with the remainder considered return of capital.

Should I take financial advice before buying an annuity?

For pension pots over £100,000, professional financial advice is strongly recommended. Advisers can help optimize your choices, potentially increasing your lifetime income by thousands of pounds. Free guidance is available through Pension Wise for those aged 50+.
