Pensions UK: Your Complete Guide to Building and Protecting Your Retirement Pot

Why pensions matter
Let's be honest: pensions aren't exactly the most thrilling topic. But here's the thing. They're probably the single most powerful financial tool you have access to, and most people are dramatically underusing them. Whether you're 25 and just starting out, 45 and playing catch-up, or 60 and eyeing the finish line, understanding your pension could be the difference between a retirement you love and one you merely survive.
When you die, your pension usually passes outside your will, to whoever you've named on your provider's "expression of wish" form. How it's taxed depends on your age at death: pension benefits paid before age 75 are typically tax-free for your beneficiaries; after 75, they're taxed as income. Getting this form right is one of the highest-leverage five minutes in your entire financial plan.
Keeping your pension nomination forms current is one of those five-minute jobs that quietly decides where serious money goes. Going through my father's affairs, the nominated beneficiaries were exactly where the largest, simplest transfers happened, precisely because he'd kept the paperwork straight. An out-of-date form can send your pension to the wrong person entirely; a current one is a gift to whoever you actually love.
The expression of wish form
Most defined contribution pensions are held in a trust structure, and your provider asks you to complete an "expression of wish" (sometimes called a "nomination of beneficiary") form when you join. This tells the scheme's trustees who you'd like to benefit if you die before you've drawn it all down.
Crucially, this form isn't legally binding. The trustees retain discretion over who actually receives the money, which sounds alarming, but in practice this discretion is exactly what keeps the money outside your estate for inheritance tax purposes (for now; see below), and trustees follow a clear expression of wish in the overwhelming majority of cases. The real risk isn't the trustees ignoring your wishes; it's the form being wrong or dangerously out of date. Divorced but never got round to changing it? Your ex could still be first in line. New partner, new child, never updated it? They might get nothing.

Defined Contribution vs Defined Benefit: different rules on death
Defined contribution (DC) pensions pass to your nominated beneficiary or beneficiaries, usually as either a lump sum or continued drawdown they manage themselves. The tax treatment hinges on one number: your age when you die.
Die before age 75: benefits are usually paid to your beneficiaries completely free of income tax, whether taken as a lump sum or drawdown, provided they're claimed within two years.
Die at 75 or older: benefits are still paid to your beneficiaries, but they're taxed as income at their own marginal rate, whatever that happens to be.
That age-75 cliff edge is worth knowing about if you're managing how and when you draw down your own pension in later life, it's a genuine planning consideration, not just a technicality.
Defined benefit (DB) pensions work differently again. Rather than a lump sum, they typically pay an ongoing pension to your spouse, civil partner, or dependent children (often until age 23 if still in full-time education), usually calculated as a percentage of what you would have received. If you're still employed at the point of death, many DB and workplace schemes also pay a separate death-in-service lump sum, often two to four times salary, so it's worth checking your scheme's specific rules rather than assuming.
The change coming in April 2027
As covered above, unused pension funds will be brought into the scope of inheritance tax from April 2027. This doesn't change who inherits or the expression of wish mechanism, but it will change the tax bill your beneficiaries face on top of any income tax already due under the rules above. If IHT planning has been part of why you've kept money in your pension rather than drawing it down, this is worth reviewing well before the change takes effect. See the Inheritance Tax guide for the full detail.
What types of pension are available in the UK?
The UK pension landscape has three main pillars, and most people will have access to more than one.
The State Pension
The State Pension is the government's contribution to your retirement. To receive the full new State Pension (currently £241.30 per week for 2026/27), you need 35 qualifying years of National Insurance contributions. You can check your NI record and State Pension forecast at gov.uk. Don't assume it's enough to live on. It isn't, for most people.
Workplace (Employer) Pensions
Since auto-enrolment was introduced in 2012, most employees are automatically enrolled into a workplace pension. The minimum contribution is currently 8% of qualifying earnings, split between you and your employer, with at least 3% coming from your employer. Many employers will match contributions above the minimum if you increase yours, which is essentially free money. Always contribute at least enough to get your full employer match.
Workplace pensions are typically one of two types: defined contribution (DC), where your pot depends on what's paid in and investment returns; or defined benefit (DB, also called final salary), where your retirement income is guaranteed based on your salary and years of service. DB schemes are increasingly rare in the private sector but remain common in the public sector.
Personal and Self-Invested Personal Pensions (SIPPs)
If you're self-employed, or want more control over your investments, a personal pension or SIPP may suit you. SIPPs give you access to a wide range of investment options including funds, shares, ETFs, and bonds. Providers include Vanguard, Hargreaves Lansdown, AJ Bell, and others. The trade-off for greater control is greater responsibility.
Tax: the bit that makes pensions so powerful
Pension contributions benefit from tax relief, meaning the government tops up what you put in. A basic rate taxpayer contributing £80 gets £100 into their pension. A higher rate taxpayer can effectively contribute £100 for just £60 out of pocket, though higher rate relief may need to be claimed via self-assessment.
Your annual allowance is currently £60,000 per year (or 100% of your earnings if lower). Unused allowance can be carried forward up to three years.
On withdrawal, 25% of your pension pot can typically be taken tax-free as a lump sum (up to a maximum of £268,275). The rest is taxed as income at your marginal rate, making the timing of withdrawals important. Withdrawing in a year when your income is lower reduces the tax you pay.
Important upcoming change: From April 2027, unused pension funds will be brought into the scope of Inheritance Tax for the first time. If you're using your pension as an IHT planning tool, review this urgently. See our Inheritance Tax guide for more detail.
Active vs Passive Funds: What Should Your Pension Invest In?
Most workplace and personal pensions invest your contributions in funds. There are two broad approaches.
Passive funds (also called index funds or trackers) simply follow a market index, like the FTSE 100 or S&P 500. They have low fees and, over the long term, frequently outperform actively managed alternatives. Vanguard's LifeStrategy range and similar products are popular examples.
Active funds are managed by professionals who aim to beat the market. They carry higher fees and, statistically, most fail to outperform their benchmark over the long term, though some do, particularly in less efficient markets.
For most people, a low-cost passive fund is a sensible core holding, with active funds considered only for specific satellite positions.
Risk appetite and the age question
How your pension is invested should shift as you age, a concept known as lifestyling.
In your 20s and 30s, time is your greatest asset. You can afford to take on more risk through equities and growth funds, because you have decades to ride out market volatility. A 30% fall in your pot at 30 is a buying opportunity. At 64, it's a crisis.
In your 40s, many experts say that you should continue to hold growth assets but begin thinking about balance. A diversified mix of equities and bonds starts to make sense.
In your 50s, gradually reducing risk exposure is sensible. Many pension providers offer automatic lifestyling that does this for you. Check whether your scheme uses it and whether it suits your planned retirement age and drawdown strategy.
In your 60s and beyond, your strategy depends on how you plan to access your pension. If you're taking drawdown, you can maintain some growth exposure. If you're buying an annuity, you'll want lower-risk assets in the run-up to purchase.
Accessing your pension: your options at retirement
From age 57 (rising from 55 in 2028), you can access your defined contribution pension. Your main options are:
Drawdown: Keep your pot invested and withdraw as needed. Flexible, but requires ongoing management and carries investment risk.
Annuity: Exchange your pot for a guaranteed income for life. Rates have improved significantly since 2022 as interest rates rose. Less flexible, but removes longevity risk.
Lump sum withdrawals: Take chunks out as needed, with 25% of each withdrawal tax-free.
A combination of the above, which many people find works best.
A few common pension mistakes to avoid
Not increasing contributions when your salary rises. Even 1% more makes a significant difference over decades.
Losing track of old workplace pensions. The government's Pension Tracing Service can help reunite you with lost pots.
Ignoring the default fund. Many workplace pension default funds are conservative and may not match your risk appetite or time horizon.
Assuming the State Pension alone is enough. At £241.30 per week, it isn't for most lifestyles.
Start earlier, contribute more, review often
The best pension decision you can make is the one you make today, whatever your age. The compounding effect of investment returns over decades is remarkable, but only if you give it time to work. Review your pension annually, increase contributions when you can, and get professional advice if your situation is complex. Just as important, ensure you keep your expression of wish(es) up to date with the right beneficiaries and allocations!

About the founder. I'm Alex Johnson, and I built Not So Grave after my father died suddenly in 2023. Going through his estate taught me more about death planning than any guide I could find at the time, partly because of the documents he'd left, and partly because of the gaps where he hadn't. I'm not a solicitor or a financial adviser, and I'll always tell you when to use one. What I am is someone who's been through it and wants to make your turn easier.
