What Is a Pension? UK Pensions Explained Simply

The simple version

A pension is a pot of money you build up during your working life to live on when you retire. You get tax relief on contributions — meaning the government tops up what you put in — and the money grows largely free of tax while invested. You can usually access it from age 57 (rising to 57 in 2028, previously 55).

There are two main types: the State Pension (paid by the government, based on your National Insurance record) and private pensions (workplace or personal pensions where you build up your own pot).

The State Pension

The full new State Pension is currently £221.20 per week (2024/25), or about £11,500 per year. You get this from State Pension age (currently 66, rising to 67 between 2026–2028).

To get the full amount you need 35 qualifying years of National Insurance contributions — either from working and paying NI, or from NI credits (which you can get if you’re a carer, claiming certain benefits, or looking after a child). You need at least 10 years to get anything at all.

You can check your State Pension forecast on the Government Gateway website (gov.uk/check-state-pension).

Workplace pensions and auto-enrolment

Since 2012, employers are legally required to automatically enrol eligible workers into a workplace pension. If you’re aged 22–66, earning over £10,000 per year, you’ll be enrolled automatically.

The minimum contributions (2025/26):

• You contribute: 5% of your qualifying earnings (includes tax relief)
• Your employer contributes: at least 3%
• Total minimum: 8% of qualifying earnings

Qualifying earnings are calculated on the band between £6,240 and £50,270. So on a £30,000 salary, contributions are calculated on £23,760 — not the full £30,000.

Employees can opt out of auto-enrolment if they choose. If you opt out, your employer’s contribution also stops. The Pensions Regulator publishes guidance on auto-enrolment rights at thepensionsregulator.gov.uk.

How does the tax relief work?

This is the most powerful benefit of pensions. For every £80 you put into a pension, the government adds £20 (basic rate taxpayers), making £100 in your pot. Higher-rate taxpayers can claim an additional 20% back through their Self Assessment tax return.

• Basic rate (20% tax): government adds 25p for every £1 you contribute
• Higher rate (40% tax): effectively costs you £60 for every £100 in your pension
• Additional rate (45% tax): effectively costs you £55 for every £100

The annual limit for tax-relieved contributions is £60,000 (or 100% of your earnings if lower) — this is called the Annual Allowance.

Defined contribution vs defined benefit

• Defined contribution (DC): the most common type today. You build up a pot, invest it, and the final amount depends on how much was paid in and how investments performed. At retirement, you decide how to use the pot — take a regular income (annuity), draw it down flexibly, or a mix.
• Defined benefit (DB) / final salary: mostly found in the public sector now. Your pension is guaranteed based on your salary and years of service. Rarer and more valuable — don’t give one up without careful thought.

Retirement Living Standards (PLSA)

The Pensions and Lifetime Savings Association (PLSA) publishes annual ‘Retirement Living Standards’ — illustrative income benchmarks based on research into what different retirement lifestyles cost. These are not official government figures, but are widely referenced:

• Minimum: £14,400/year (single) — covers essentials with some flexibility
• Moderate: £31,300/year (single) — greater financial security
• Comfortable: £43,100/year (single) — more leisure and travel

These are illustrative benchmarks only, published by the PLSA. Individual retirement needs vary significantly. The full PLSA standards are available at plsa.co.uk.
