A pension is a long-term savings plan specifically designed for retirement. Contributions benefit from tax relief under HMRC rules, and the money grows largely free of tax while invested. Yet millions of people in the UK don’t fully understand how theirs works. Here’s the plain-English version.
A pension is a long-term savings plan that gives you income in retirement. You receive tax relief on contributions, the government tops up what you pay in, and the money grows largely free of tax while invested. Most people can access their pension from age 55 (rising to 57 in April 2028). There are two main types: the State Pension, paid by the government, and private pensions built up through work or personal saving.
The State Pension is a regular payment from the UK government, funded by your National Insurance record. The full new State Pension is £221.20 per week in 2025/26 (approximately £11,500 per year). You need 35 qualifying NI years for the full amount, earned through work, or NI credits if you are a carer or claiming certain benefits. You need at least 10 qualifying years to receive anything. State Pension age is currently 66, rising to 67 between 2026 and 2028.
You can check your State Pension forecast on the Government Gateway website (gov.uk/check-state-pension).
Since 2012, employers must automatically enrol eligible workers into a workplace pension scheme. If you are aged 22 to 66 and earn over £10,000 per year, you are enrolled automatically. The minimum total contribution is 8% of qualifying earnings, at least 3% from your employer and 5% from you (including tax relief). You can opt out, but you lose your employer’s contributions if you do.
The minimum contributions (2025/26):
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.
Pension tax relief means the government tops up your pension contributions at your marginal income tax rate. A basic-rate taxpayer who pays in £80 effectively gets £100 in their pension pot, the government adds £20. Higher-rate taxpayers can claim a further 20% back through Self Assessment, and additional-rate taxpayers a further 25%, making pensions one of the most tax-efficient ways to save.
The annual limit for tax-relieved contributions is £60,000 (or 100% of your earnings if lower), this is called the Annual Allowance.
A defined contribution (DC) pension builds up a pot based on how much you and your employer pay in and how the investments perform, the most common type in the UK today. A defined benefit (DB) pension pays a guaranteed income in retirement based on your salary and years of service, and is now mostly found in the public sector.
The Pensions and Lifetime Savings Association (PLSA) publishes widely referenced annual benchmarks for retirement income: roughly £14,400 per year for a minimum lifestyle, £31,300 for a moderate retirement, and £43,100 for a comfortable one (all figures for a single person). These are illustrative estimates, not official targets, individual needs vary significantly.
These are illustrative benchmarks only, published by the PLSA. Individual retirement needs vary significantly. The full PLSA standards are available at plsa.co.uk.
A defined benefit (DB) pension pays a guaranteed income in retirement based on your salary and years of service, often called a final salary pension. A defined contribution (DC) pension builds up a pot based on contributions and investment returns; the income you receive in retirement depends on how much was saved and how the investments performed.
The annual allowance is the maximum amount that can be paid into your pension pots each tax year while still receiving tax relief. For 2025/26 it is £60,000, or 100% of your earned income if that is lower. Contributions above this limit may result in a tax charge. Those who have already flexibly accessed their pension pot face a reduced money purchase annual allowance.
The minimum pension access age for most people is currently 55, rising to 57 in April 2028. The State Pension age is 66 for both men and women, and is scheduled to rise to 67 between 2026 and 2028. Some workplace schemes have different rules, so it is worth checking the terms of your specific pension arrangement.
Under auto-enrolment rules, employers must enrol eligible workers into a workplace pension and contribute at least 3% of qualifying earnings. Workers themselves must contribute at least 5%, giving a minimum total of 8%. Employers may offer higher contributions, the specific terms depend on your workplace scheme.
When you pay into a pension, the government tops up your contributions with tax relief at your marginal income tax rate. A basic-rate taxpayer contributing £80 effectively has £100 paid into their pension. Higher and additional-rate taxpayers can claim further relief through their self-assessment tax return. This is one reason pensions are a tax-efficient way to save for retirement.
