What is auto-enrolment?

Automatic enrolment is a UK government initiative designed to help more people save for their retirement. As an employer, if you have at least one member of staff, you have legal duties to provide and contribute to a workplace pension scheme.

These duties apply to all businesses, regardless of their size. It's an ongoing obligation, requiring you to assess your workforce regularly, manage contributions, and communicate with your employees.

Your employer duties

Your auto-enrolment duties begin on the day you employ your first eligible employee. You then have a six-week period to set up a scheme and enrol them. You can choose to delay this by up to three months using 'postponement'.

Here's a breakdown of your key responsibilities:

  • Assess your staff: Every time you run payroll, you must assess each worker to determine their eligibility for auto-enrolment.
  • Eligible jobholders: Must be automatically enrolled. They are aged 22 to State Pension age, earn above the earnings trigger of £10,000 per year, and work in the UK.
  • Non-eligible jobholders: Have the right to opt in to a workplace pension scheme. If they do, you must contribute. These are workers aged 16 to 21 or State Pension age to 74 earning above the earnings trigger, or those aged 16 to 74 earning between the lower qualifying earnings limit (£6,240) and the earnings trigger (£10,000).
  • Entitled workers: Have the right to join a pension scheme, but you are not legally required to contribute. These are workers aged 16 to 74 earning below the lower qualifying earnings limit of £6,240 per year.
  • Set up a pension scheme: You must choose a pension scheme that meets the Pensions Regulator's requirements for automatic enrolment.
  • Make contributions: You and your eligible employees must make minimum contributions to the scheme.
  • Communicate with staff: You must provide specific information to your employees about how auto-enrolment affects them. This includes an enrolment letter within six weeks of their enrolment date, detailing the scheme, contributions, and how to opt out. If using postponement, you must issue a postponement notice.
  • Complete a Declaration of Compliance: Shortly after your duties start date, you must complete an online declaration with The Pensions Regulator (TPR) to confirm you've met your legal duties. This must be done no later than five months after your duties start date.

Minimum contribution rates

For the 2026/27 tax year, the total minimum contribution to a workplace pension is 8% of an employee's 'qualifying earnings'.

  • Employer contribution: You must contribute at least 3%.
  • Employee contribution: The employee contributes 5%, which includes tax relief from the government.

These contributions are calculated on 'qualifying earnings', which for 2026/27 are earnings between £6,240 and £50,270 per year (figures for illustration — check current rates). Some employers may choose to calculate contributions on total earnings, which can result in higher contributions.

Re-enrolment

Every three years, you must carry out 're-enrolment'. This means automatically re-enrolling eligible employees who have previously opted out or stopped contributing to the pension scheme.

You must choose a re-enrolment date within a six-month window around the third anniversary of your original duties start date or last re-enrolment date. Postponement cannot be used at the point of re-enrolment. After re-enrolling staff, you must submit a re-declaration of compliance to TPR within five months of your re-enrolment date.

Common mistakes

  • Missing deadlines: Failing to set up a scheme, enrol staff, or submit your Declaration of Compliance by the deadlines can lead to penalties from The Pensions Regulator.
  • Incorrectly assessing staff: Not correctly identifying eligible jobholders, non-eligible jobholders, or entitled workers can lead to non-compliance.
  • Incorrect contributions: Paying too little or calculating contributions on the wrong earnings basis.
  • Poor record-keeping: You must keep accurate records of your auto-enrolment activities for a specified period.
  • Inducement to opt out: You must not encourage or pressure employees to opt out of the pension scheme.
