Auto-enrolment is the UK system that requires employers to automatically put eligible staff into a workplace pension and contribute to it. It is a legal duty, not optional, and the answer to "do I need to make contributions?" is, for most employers, yes. Here is a plain-English guide for England and Wales under the Pensions Act 2008.
What auto-enrolment is
Under the Pensions Act 2008, every employer must:
- assess their staff;
- automatically enrol eligible workers into a qualifying workplace pension scheme; and
- make minimum employer contributions, on top of the worker's own contributions.
It is overseen by The Pensions Regulator (TPR), which can issue penalties for non-compliance.
Who must be enrolled?
You must automatically enrol "eligible jobholders", broadly workers who:
- are aged between 22 and State Pension age;
- earn over £10,000 a year (the earnings trigger); and
- work in the UK.
Other staff (e.g. younger workers, or those earning less) have rights to opt in, and some lower earners are entitled to employer contributions if they ask to join. Workers can opt out after being enrolled (and get a refund if they do so quickly), but you must not encourage them to.
How much must you contribute?
The minimum total contribution is 8% of qualifying earnings, of which the employer must pay at least 3% (the worker typically makes up the rest, with tax relief). "Qualifying earnings" are earnings within a band (a lower and upper limit reviewed each year). You can contribute more, and some schemes use different (certified) bases.
Your ongoing duties
- Enrol eligible staff and pay contributions from the start (the duties apply from your first member of staff).
- Write to staff explaining their enrolment and rights.
- Manage opt-outs/opt-ins correctly and on time.
- Re-enrol eligible staff who previously opted out roughly every three years.
- Complete a declaration of compliance with TPR, and keep records.
- Maintain contributions and pay them across on time.
What happens if you don't comply
The Pensions Regulator can issue compliance notices and fixed and escalating penalties for failing to enrol staff, pay contributions or complete the declaration. Persistent or wilful non-compliance can lead to court action. Compliance is therefore essential.
Practical tips
- Set up a qualifying scheme in good time (many employers use a master-trust provider).
- Automate assessment and contributions through your payroll.
- Budget for the employer contribution as a real cost of employing staff.
- Diarise re-enrolment and the declaration deadlines.
Key takeaways
- Auto-enrolment (Pensions Act 2008) requires employers to enrol eligible staff into a workplace pension and contribute, it is a legal duty.
- Eligible jobholders are aged 22 to State Pension age, earning over £10,000, working in the UK; others can opt in.
- The minimum total contribution is 8% of qualifying earnings, with the employer paying at least 3%.
- You must enrol, communicate, manage opt-outs, re-enrol every ~3 years and declare compliance, or face TPR penalties.
