Not all pensions are the same. The type of pension you have determines how much you get in retirement, who bears the investment risk, and how flexible your options are. This guide explains the main UK pension types and how they compare.

Defined Benefit Pensions

A defined benefit (DB) pension — often called a final salary or career average pension — promises you a guaranteed income for life when you retire. The amount is calculated using a formula based on your salary and years of service, not on how much you or your employer paid in.

How They Work

Example Calculation

A typical DB scheme might use a formula of 1/60th of final salary per year of service. If you worked 30 years and your final salary was £50,000:

30 years ÷ 60 × £50,000 = £25,000 per year for life

Availability

DB pensions are increasingly rare in the private sector. Most have closed to new members. You’re most likely to find them in:

If you have a DB pension, it is extremely valuable. Think carefully before transferring — the guaranteed income is something no other product can reliably replicate.

Defined Contribution Pensions

A defined contribution (DC) pension — also called a money purchase pension — is a pot of money built up from contributions from you, your employer, or both. The final value depends on how much goes in and how the investments perform.

Where You’ll Find Them

State Pension

The UK State Pension is a weekly payment from the government, based on your National Insurance (NI) contribution record.

How Much You Get

As of the 2025/26 tax year, the full new State Pension is £221.20 per week (around £11,500 per year). To receive this, you need 35 qualifying years of NI contributions or credits.

You can receive a partial State Pension with 10 to 34 qualifying years. With fewer than 10 years, you get nothing.

Important Points

NI Credits

You receive NI credits automatically if you’re:

Workplace Pensions (Auto-Enrolment)

Since 2012, UK employers have been required to automatically enrol eligible workers into a workplace pension. This is the most common way people save for retirement.

Minimum Contributions

Qualifying earnings for 2025/26 are between £6,240 and £50,270 per year. Many employers match higher contributions — always check if you can get more from your employer.

Personal Pensions and SIPPs

A personal pension is a pension you set up yourself, separate from any workplace scheme. A Self-Invested Personal Pension (SIPP) is a type of personal pension that gives you a wider range of investment choices.
