Since 2012, all UK employers have been required to automatically enrol eligible workers into a qualifying workplace pension scheme — one of the most significant employment law changes of the last decade. The minimum total contribution is 8%: 5% from the employee (via salary sacrifice, net pay or relief at source) plus 3% from the employer. Non-compliance is enforced by The Pensions Regulator (TPR) and carries escalating fines that can reach £10,000/day for the largest employers. This guide covers eligibility rules, the enrolment process, the 3-yearly re-enrolment cycle, opt-outs + TPR enforcement powers.
Checked against the 2 sources listed below · Last reviewed 14 June 2026
Automatically enrol workers who are:
- Aged 22 to State Pension age
- Earning above £10,000/year (or £192/week)
- Working in the UK
Non-eligible jobholders (aged 16-21 or above SPA, earning £6,240-£10,000) can opt IN.
Entitled workers (earning below £6,240) can join but no employer contribution required.
Minimum contributions
Employee: 5% (of qualifying earnings £6,240-£50,270)
Employer: 3% (of qualifying earnings)
Total: 8%
Employer can pay all 8% + reduce employee share to zero.
Opt-out
Workers may opt out within 30 days of enrolment for full refund of contributions. After 30 days, contributions stay in scheme.
Re-enrolment
Every 3 years, employers must automatically re-enrol workers who previously opted out. Same eligibility rules apply.
Compliance + penalties
TPR enforcement:
- Fixed penalty: £400
- Escalating penalty: £50-£10,000/day depending on employer size
- Compliance notice: TPR direction to fix within specified period
Salary sacrifice pension option
Employers can offer salary sacrifice pension arrangement:
- Employee agrees to reduce gross salary in exchange for equivalent employer pension contribution
- Both save NI (employee saves 8%, employer saves 15%)
- Some employers share NI saving with employee via increased contribution
In short
Auto-enrolment = 8% total minimum, 3-year re-enrolment cycle, escalating penalties. Salary sacrifice option saves NI for both parties.
Frequently asked questions
Can I opt my employees out?
No — employer cannot opt employees out. Only employee can opt out, within 30 days of enrolment.
What if I miss the auto-enrolment deadline?
TPR issues compliance notice + fixed £400 penalty. Continued non-compliance = escalating penalties up to £10,000/day.
Does salary sacrifice count towards auto-enrolment minimum?
Yes — sacrifice pension arrangement satisfies the minimum contribution requirement if total contribution ≥ 8% of qualifying earnings.
Do I need to enrol part-time workers?
Yes if they earn over £10,000/year. Part-time workers earning below threshold can opt in voluntarily.
