Pensions Explained For Dummies

Do you know how much is in your pension? Do you know what it’s invested in? Do you have a target pot you’re saving for?

If you answered yes to all three, you’re in the minority. If you’re in your 20s or 30s and answered yes, you’re a rare breed.

Most people, especially younger savers, find pensions confusing. That’s not because they aren’t clever. The financial industry often does a poor job of explaining them, so people either pay for advice or never start.

Pensions can be tricky. But the basics, which are all most people need, aren’t hard to learn. This guide covers what you need to know in plain English, with the rules for the 2026/27 tax year.

When investing, your capital is at risk. The value of your pension can go down as well as up.

What is a pension?

A pension is a long-term savings pot for one purpose: funding your retirement. You save a little from each pay packet so you have money to live on when you stop working.

The money in most pensions is invested in shares, bonds, property, cash and other assets. Exactly what you hold depends on the funds you choose, or the default fund your provider picks for you.

There are different types of pension, which we explain below. They all do the same job: building a pot that pays your living costs once you stop working.

Why are pensions important?

Without a pension, you’d have to keep working or rely on someone else for support. In the UK, that someone else is usually the government, and its support isn’t generous.

In 2026/27, the full new State Pension is £241.30 a week, or £12,547.60 a year. Some people get less. That’s below the £13,900 a year that Pensions UK estimates a single person needs for a “minimum” standard of living in retirement.

Not saving enough can mean a hard old age. In 2023/24, 1.9 million pensioners (16%) were in relative poverty after housing costs, according to Age UK, using government data.

I don’t want to spend my last years counting pennies, and that’s enough motivation for me to save. So, let’s look at what makes pensions worth it.

The benefits of pensions

To avoid relying on the State Pension alone, you need a private pension on top. The government encourages this with some generous perks.

1. Auto-enrolment

If you’re employed, aged 22 or over (and under State Pension age) and earn more than £10,000 a year, your employer must automatically enrol you in a workplace pension.

The minimum total contribution is 8% of your “qualifying earnings”, the part of your pay between £6,240 and £50,270 a year. At least 3% must come from your employer. The rest comes from you, including tax relief.

Auto-enrolment does you a favour. Money goes into your pension every payday before you can spend it. This is paying yourself first, and it removes the temptation to spend that money on things you don’t need.

2. Employer contributions

Still annoyed at being “forced” to save? Here’s the sweetener: your employer must pay in at least 3% of your qualifying earnings on top of your own contribution. Many employers pay more, especially if you increase your own contribution.

This money doesn’t come out of your salary, so in effect it’s free money. Few jobs offer many perks beyond free tea and coffee, so take it.

Only opt out of your workplace pension if you’re facing real financial hardship. A 3% top-up may not look like much now, but it adds up over a career.

3. Tax relief

The third big benefit is tax relief. An easy way to think about it: you don’t pay tax on the way in, but you do on the way out.

A £100 contribution only costs a basic-rate taxpayer £80. For higher-rate taxpayers it costs £60, and for additional-rate taxpayers £55. Higher and additional-rate taxpayers may need to claim the extra relief through a Self Assessment tax return. Rates differ slightly in Scotland.

Investment income and gains inside a pension are also tax-free.

You can’t avoid tax completely, though. Up to 25% of your pension can usually be taken tax-free. The rest is taxed as income when you withdraw it. By then, your pot has had years of growth on money that was never taxed, so you start with a bigger pot for compound growth to work on.

Types of pension

Having several types of pension makes things confusing. The good news is that most people have a workplace pension set up by their employer. Workplace pensions come in two types: defined contribution and defined benefit.

What is a defined contribution pension?

Most people have a defined contribution pension. Your pot depends on how much you and your employer pay in and how your investments perform.

From age 55, rising to 57 on 6 April 2028, you have several ways to access it:

• Take up to 25% as a tax-free lump sum.
• Withdraw the rest in one go and pay income tax on it.
• Leave the rest invested and withdraw it when you need to (drawdown).
• Buy an annuity, which pays a guaranteed income for the rest of your life.

You can mix these options. For example, take a lump sum, buy an annuity for a steady income and leave the rest invested.

These “pension freedoms” give you flexibility, but you need to make sure your money lasts. If you’re 50 or over, you can get free, impartial guidance from Pension Wise.

What is a defined benefit pension?

A defined benefit pension pays a guaranteed income in retirement, based on your salary and how long you were in the scheme. Older schemes are based on your final salary. Most public sector schemes now use your average salary across your career.

Defined benefit pensions are now rare in the private sector. They’re still common in the public sector, for example for NHS staff, teachers, civil servants, council staff, the police and the armed forces.

Workplace pension facts you need to know

• Annual allowance: you can get tax relief on pension contributions up to £60,000 a year, or 100% of your earnings if lower. The allowance is lower for very high earners and for people who have already started taking taxable money from their pension.
• Lifetime allowance: this limit was abolished from 6 April 2024. There’s now a cap of £268,275 on the total tax-free cash most people can take.
• Inheritance tax: from 6 April 2027, most unused pension pots will count towards your estate for inheritance tax.
• Old pensions: if you’ve changed jobs a few times, you probably have several pensions. Combining them makes them easier to manage, but check you won’t lose valuable benefits or pay exit fees. The government’s Pension Tracing Service can help you find lost pensions.
• Defined benefit transfers: you can transfer a defined benefit pension to a defined contribution one, but you’ll usually lose a guaranteed income for life. If the transfer value is over £30,000, you must take regulated financial advice first. For most people, staying put is the better choice.

What is a SIPP?

SIPP stands for self-invested personal pension.

If you’re self-employed or don’t qualify for a workplace pension, a SIPP lets you save for retirement with the same tax relief: £100 in your pension costs a basic-rate taxpayer £80. Even people with no earnings can pay in up to £2,880 a year and get it topped up to £3,600.

The big downside of a SIPP is that there’s no employer contribution. If you’re in a workplace scheme, pay in enough to get the full employer match first. Don’t turn down free money.

If you need to save more to reach your retirement goal, a SIPP alongside your workplace pension can help. If you enjoy investing, a SIPP lets you choose your own investments, from funds to individual shares. You can pay in regularly or add lump sums when you have spare cash.

What is a SSAS?

The least well-known type of pension is the SSAS (small self-administered scheme). It’s usually set up by a small group of company directors or key staff, who act as its trustees.

A SSAS offers more investment options than most pensions. For example, it can buy the company’s business premises and lease them back to the business. It can also borrow money, up to 50% of its net assets, for instance to buy property with a mortgage. A SSAS is complex, so most people use a specialist administrator and adviser.

State Pension

Last but not least is the State Pension. You shouldn’t rely on it alone, but it will form part of your retirement income.

You can claim it from State Pension age, currently 66. It rises to 67 between 2026 and 2028, and is due to rise to 68 between 2044 and 2046, although the government is reviewing this.

To get the full new State Pension, you need 35 qualifying years of National Insurance contributions or credits. To get any State Pension, you need at least 10. The full rate is £241.30 a week (£12,547.60 a year) in 2026/27. You can check your forecast on GOV.UK.

State Pension facts you need to know

• You receive the State Pension from the day you’re eligible for the rest of your life.
• The “triple lock” means it rises each April by the highest of 2.5%, inflation or average earnings growth.
• You can fill gaps in your National Insurance record by making voluntary contributions.
• You can defer your State Pension. It increases by 1% for every 9 weeks you delay, which is about 5.8% for each full year.

Wrapping it up

I named this post “pensions explained for dummies”, but you’re not stupid if you find pensions confusing. There’s a lot to take in.

I hope this guide has made the subject clearer and shown how important it is to save for retirement. Don’t put off starting or paying in more just because you’re unsure what to do. The sooner you start, the better, but it’s never too late.
