What Is Auto-Enrolment and Do I Need It?
If you employ staff in the UK, auto-enrolment is not optional. Since its introduction in 2012, workplace pension auto-enrolment has become one of the most significant ongoing compliance obligations for UK employers of all sizes. Yet it remains one of the most misunderstood — and one of the most common sources of penalties from The Pensions Regulator. Here is everything you need to know.
What is auto-enrolment?
Auto-enrolment is the legal requirement for employers to automatically enrol eligible workers into a qualifying workplace pension scheme and contribute on their behalf. Workers don’t need to ask to join — they are enrolled by default and must actively choose to opt out if they don’t want to take part.
The policy has been hugely successful. Workplace pension participation rose from 47% in 2012 to over 88% by 2023, with millions of workers now building pension savings — many for the first time — with employer contributions added on top.
Does auto-enrolment apply to my business?
Yes — if you employ at least one member of staff, auto-enrolment duties apply to you. There is no minimum business size. The only exception is a limited company where the sole director is also the only worker and there are no other employees.
Your duties begin from the day your first member of staff starts working for you — your duties start date. Even if none of your workers need to be enrolled straight away, you still have duties to complete, including assessing all workers and declaring your compliance to The Pensions Regulator.
Who must be automatically enrolled?
Workers fall into three categories based on age and earnings:
- Eligible jobholders — must be automatically enrolled. These are workers aged 22 to State Pension age, earning above £10,000 a year, who work or ordinarily work in the UK. Both employer and employee must contribute.
- Non-eligible jobholders — not automatically enrolled, but can opt in. These are workers aged 16 to 74 earning between £6,240 and £10,000, or workers aged 16 to 21 or State Pension age to 74 earning above £10,000. If they opt in, the employer must contribute at the same minimum rates.
- Entitled workers — earn below £6,240 a year. They can ask to join a pension scheme, but the employer doesn’t have to contribute.
You must assess every worker against these criteria on your duties start date — and every time you take someone on.
What are the 2026/27 auto-enrolment thresholds?
For the 2026/27 tax year, the thresholds are unchanged from last year:
- Earnings trigger for automatic enrolment: £10,000 a year (£833 a month / £192 a week).
- Lower earnings limit (bottom of the qualifying earnings band): £6,240 a year (£520 a month / £120 a week).
- Upper earnings limit (top of the qualifying earnings band): £50,270 a year (£4,189 a month / £967 a week).
Contributions are calculated on qualifying earnings — the part of pay between £6,240 and £50,270, not every pound earned. Some employers choose to calculate contributions on total earnings or use a different definition of pensionable pay, which can be more generous.
What are the minimum contribution rates?
The minimum rates have been in place since April 2019 and are unchanged for 2026/27:
- Employer minimum: 3% of qualifying earnings.
- Employee minimum: 5% of qualifying earnings (including tax relief).
- Total minimum: 8% of qualifying earnings.
These are minimums — employers can choose to contribute more. Many do, either to attract and keep good people or as part of salary sacrifice arrangements, which can also reduce employer and employee National Insurance.
Your duties as an employer, step by step
- Choose a qualifying pension scheme that meets The Pensions Regulator’s requirements. Popular providers include NEST (the government-backed scheme), The People’s Pension, Aviva and Legal & General. Do this before your duties start date.
- Assess all workers on your duties start date and every payday after that, checking each worker’s age and earnings to see which category they fall into.
- Enrol eligible workers from their enrolment date — you have six weeks to complete the enrolment, or you can use postponement to delay assessment by up to three months. They can’t be left out even if they say they want to opt out — they must be enrolled first and can then opt out.
- Write to every worker individually, explaining how auto-enrolment applies to them, whether or not they are being enrolled.
- Pay contributions on time — by the 22nd of the month after the pay period they relate to. Late payment is one of the most common compliance failures.
- Declare compliance with The Pensions Regulator within five months of your duties start date. This is required even if nobody needed to be enrolled.
- Re-enrol every three years — re-enrol any eligible workers who previously opted out or left the scheme, and re-declare your compliance after each re-enrolment.
Can workers opt out?
Yes — but only after they have been enrolled. Workers have one month from enrolment to opt out. If they do, any contributions already deducted must be refunded. Workers who opt out will be re-enrolled every three years and will need to opt out again if they still don’t want to take part.
Importantly, employers must not encourage or induce workers to opt out, or suggest that opting out is preferable or expected. Doing so breaches auto-enrolment law and can lead to significant penalties.
What are the penalties for non-compliance?
The Pensions Regulator takes enforcement seriously. Penalties include:
- Fixed penalty notices: £400 for failing to comply with a statutory notice.
- Escalating penalty notices: £50 to £10,000 a day, depending on the number of workers, for continued non-compliance.
- Civil penalties: up to £5,000 for individuals and £50,000 for organisations for wilful non-compliance.
- Back-payment of missed contributions: employers must pay any contributions that should have been made, plus interest.
The most common failures are late payment of contributions, failing to complete the Declaration of Compliance, and failing to re-enrol workers at the three-year anniversary. All of these are avoidable with a well-run payroll process.
