Workplace pensions and auto-enrolment explained
Most UK employees are automatically enrolled into a workplace pension, with their employer paying in too. How it works, the minimum contributions and why opting out is costly.
Since auto-enrolment was introduced, most employees in the UK have been put into a workplace pension automatically. It is one of the most valuable benefits you get from a job, because your employer has to pay in alongside you, and the government adds tax relief on top. This guide explains who is enrolled, how much goes into a workplace pension, how tax relief works, and why opting out is rarely a good idea.
Who is auto-enrolled
Your employer must automatically enrol you if you are aged between 22 and state pension age, work in the UK and earn more than £10,000 a year from that job. If you earn less, or are aged 16 to 21 or above state pension age, you can usually ask to join, and depending on your earnings your employer may still have to contribute.
How much goes into your workplace pension
The legal minimum is 8% of your qualifying earnings, of which your employer must pay at least 3%. Qualifying earnings are the slice of your pay between a lower and upper threshold, currently £6,240 and £50,270 a year. Your share includes tax relief: the government adds back the basic-rate tax you would have paid on that money. Many employers pay more than the minimum, and some will match higher contributions from you, which is effectively free money.
For example, on a salary of £30,000, qualifying earnings are £23,760. At the minimum 8%, £1,900.80 a year goes into your pension. Your employer pays at least £712.80, and your own 5% of £1,188 includes about £237.60 of tax relief, so it costs you around £950 from take-home pay.
Net pay or relief at source
Pension schemes give tax relief in one of two ways. Under a net pay arrangement, contributions are taken from your pay before tax. Under relief at source, contributions come from taxed pay and the provider claims basic-rate relief from HMRC; higher-rate taxpayers can claim the extra through their tax return. Some employers offer salary sacrifice, which can also save National Insurance for both you and your employer. Your payslip and pension provider will show which applies. Our UK take-home pay calculator shows the effect of contributions on your pay.
Should you opt out?
You can opt out, and if you do so within a month of being enrolled you get your contributions back. But opting out means giving up your employer's contributions and the tax relief, which together can more than double the value of what you pay in. For most people, staying in, and increasing contributions when they can afford it, is one of the best financial decisions available. If you opt out, your employer must re-enrol you, usually every three years, and you can rejoin at any time.
How your pension is invested
Your contributions are invested, usually in a default fund chosen by the scheme, which spreads money across shares, bonds and other assets. Many default funds gradually move into lower-risk investments as you approach retirement. You can usually choose different funds if you prefer, but check the charges, as lower fees leave more money growing for you.
Keeping track of your pensions
If you change jobs, you may end up with several small pensions. Keep a note of each provider, update your address with them, and consider combining pots once you understand any charges or benefits you would lose. The government's Pension Tracing Service can help find old pensions. Some people combine pots into a self-invested personal pension for more control; see our guide to the SIPP.
Workplace pensions and the state pension
Your workplace pension sits on top of the state pension, which on its own provides a modest income. Read our guide to the UK state pension for 2026/27 to see how much you can expect, and plan your workplace contributions accordingly.
