Auto-Enrolment
Also known as: Automatic enrolment
In simple terms
Auto-enrolment is the rule that means most employees are automatically signed up to a workplace pension, with the employer paying in too — you have to actively opt out to leave.

What does auto-enrolment mean?
Automatic enrolment is a legal duty on employers to put eligible staff into a workplace pension and to contribute to it. It was introduced to help more people save for retirement without having to opt in.
You are normally eligible if you are aged between 22 and State Pension age, earn over a set threshold, and work in the UK.
How auto-enrolment works
Your employer enrols you and starts deducting pension contributions from your pay, adding their own contribution and tax relief. The current minimum total contribution is 8% of qualifying earnings, with at least 3% from the employer.
You can choose to opt out, usually within a set window to get a refund of early contributions, and employers must re-enrol eligible staff roughly every three years.
How could this affect me?
Auto-enrolment means you are likely already building a pension with help from your employer and the taxman. Staying in almost always makes sense, because opting out means turning down the employer contribution.
If money is tight, it is worth weighing the short-term take-home pay against the long-term value of the employer’s contribution before opting out.
Things to watch out for
- Opt out and you lose the employer contribution and tax relief.
- The minimum 8% may not be enough for the retirement you want.
- Very low earners or the under-22s may not be enrolled automatically — you can often ask to join.
Know your rights
- Employers must automatically enrol eligible workers and pay at least the minimum contribution (Pensions Act 2008 / The Pensions Regulator).
- You have the right to opt out and, within the opt-out window, to a refund of your contributions.
- Employers must re-enrol eligible staff periodically and cannot encourage you to opt out.
