Auto-Enrolment Basics for Employers

Last reviewed: 1 January 2026

The legal duty

Every UK employer must automatically enrol "eligible jobholders" into a workplace pension and contribute towards it.

Who is an eligible jobholder?

  • Aged 22 to State Pension age
  • Earns over £10,000/year (£833/month, £192/week)
  • Works in the UK

Workers outside these bands may still have the right to opt in.

Minimum contributions (since April 2019)

Contributions are calculated on qualifying earnings (£6,240 – £50,270 in 2024/25) unless you use a certified alternative basis.

Choosing a pension scheme

Most SMEs use one of:

  • NEST — government-backed, no charges for employers
  • The People's Pension — flexible, popular with payroll software
  • Smart Pension — strong tech integration

Your duties

  1. Assess every worker on each payday
  2. Enrol eligible jobholders within 6 weeks
  3. Write to each worker explaining their options
  4. Re-enrol any opt-outs every 3 years
  5. Complete a Declaration of Compliance with The Pensions Regulator within 5 months of duties start date

Penalties start at £400 fixed and escalate to £10,000+ per day for large employers.
