What is a pension?

What you'll learn

Understand what a pension actually is and the three main types you will meet.

A pension is simply a tax-advantaged pot for your retirement. Like an ISA, it is a wrapper: the money inside grows sheltered from tax, and you cannot touch it until a set minimum age. The point is to swap money you do not need today for income later, with the tax system giving you a leg up along the way.

There are three main types you will meet.

Pension typeWho runs itIn plain English
State pensionThe governmentA weekly income built from your National Insurance record
Workplace pensionYour employer's schemeAuto-enrolled at work; you and your employer both pay in
Personal pension / SIPPYouOne you open yourself and control, often called a self-invested personal pension

Why "wrapper" matters

The pension is the box. Inside it sits the actual money: cash, funds or shares that grow over time. The wrapper just decides how that money is taxed. Most workplace and personal pensions are invested, which is why they can grow over decades.

How they fit together

Most people end up with a mix. The state pension provides a base. A workplace pension usually does the heavy lifting because your employer pays in too. A personal pension or SIPP is an extra pot you can add if you want more control or are self-employed.

Key takeaways

  • A pension is a tax-advantaged wrapper for retirement money, not an investment in itself.
  • The three main types are state, workplace and personal (SIPP).
  • The state pension comes from your National Insurance record; workplace and personal pensions are usually invested pots.
  • You cannot access private pensions until a government-set minimum age, lower than state pension age.

Frequently asked questions

Is a pension an investment?

A pension is a tax-advantaged wrapper for retirement money, much like an ISA is for general saving. What grows is the cash, funds or shares held inside it.

When can I access a pension?

Private and workplace pensions have a minimum access age set by the government, which is lower than state pension age. The exact age changes over time, so check the current rule on gov.uk.

Do I get the state pension automatically?

No. It is based on your National Insurance record over your working life. You can check your forecast on gov.uk.
