Auto-enrolment is one of the most significant employment compliance obligations facing UK employers today. Since its introduction in 2012, the scheme has brought millions of workers into workplace pension saving for the first time. However, for employers – particularly small and medium-sized businesses – the ongoing compliance demands of auto-enrolment are real and can be costly to get wrong.
At Whiteline Accountancy, we manage auto-enrolment obligations for employers across the UK as part of our payroll service. In this article, we explain exactly what auto-enrolment requires, who it applies to, what the deadlines are, and what happens when employers fall short of their duties.
What Is Auto-Enrolment
Auto-enrolment is a legal obligation that requires UK employers to automatically enrol eligible workers into a qualifying workplace pension scheme. Workers are enrolled without having to take any action themselves. They can choose to opt out, but the default is enrolment – and employers cannot encourage or induce workers to opt out.
The scheme operates on the basis of minimum contribution rates. Both the employer and the worker must contribute to the pension. The current minimum contribution rates are:
- Employer minimum contribution: 3% of qualifying earnings
- Employee minimum contribution: 5% of qualifying earnings (including tax relief)
- Total minimum contribution: 8% of qualifying earnings
Qualifying earnings are currently calculated on the band of earnings between £6,240 and £50,270 per year. Earnings above and below this band are excluded from the contribution calculation under the qualifying earnings basis, though employers can choose to use a different basis if it produces a higher contribution
Who Must Be Enrolled
Not every worker must be automatically enrolled. Auto-enrolment applies to workers who meet specific age and earnings criteria. Understanding which workers fall into which category determines your obligations.
Eligible jobholders must be automatically enrolled. These are workers who are aged between 22 and State Pension age, earn above £10,000 per year from that employment, and work or ordinarily work in the UK. Eligible jobholders must be enrolled without any request from them, and you must contribute to their pension.
Non-eligible jobholders are not automatically enrolled, but they have the right to opt in. These are workers aged between 16 and 21, or between State Pension age and 74, who earn above £10,000 per year – or workers aged between 22 and State Pension age who earn between £6,240 and £10,000 per year. If a non-eligible jobholder asks to join, you must enrol them and contribute.
Entitled workers earn below £6,240 per year from that employment. They have the right to join a pension scheme, but you are not required to contribute if they do.
The distinction between these three categories matters because your obligations differ significantly between them. Misclassifying workers – for example, treating an eligible jobholder as a non-eligible one – creates a compliance failure.
Your Key Auto-Enrolment Duties as an Employer
Auto-enrolment involves a series of ongoing duties, not a one-time setup exercise. The main obligations include the following:

- Assess your workforce at each pay reference period. Workers’ eligibility can change – a worker who was not eligible last month may become eligible this month if their earnings increase or they reach age 22. You must assess eligibility every time you run payroll.
- Enrol eligible jobholders into a qualifying pension scheme within six weeks of their eligibility date. You must do this automatically – you cannot wait for the worker to ask.
- Make employer contributions on time and at the correct rate. Contributions must be paid to the pension provider by the nineteenth of the month following the pay period to which they relate.
- Write to each worker within six weeks of their first assessment date or their enrolment date, explaining their rights and the scheme they have been enrolled in. The Pensions Regulator specifies what this communication must contain.
- Process opt-outs correctly. Workers have a one-month opt-out window after being enrolled. If a worker opts out within this window, you must refund their contributions. You cannot process an opt-out before a worker has been enrolled.
- Re-enrol opted-out workers every three years. This is known as re-enrolment. Workers who previously opted out must be re-enrolled at the three-year anniversary of your staging date or duties start date. They can opt out again, but re-enrolment is mandatory.
- Complete a Declaration of Compliance with The Pensions Regulator within five months of your duties start date. This confirms that you have met your auto-enrolment obligations. Failure to submit the declaration can trigger enforcement action even where the underlying compliance is correct.
- Keep records. You must retain records of your workforce assessments, enrolments, opt-outs, contributions paid, and communications sent for at least six years. Records relating to opt-outs must be kept for four years.
Common Auto-Enrolment Mistakes Employers Make
The Pensions Regulator publishes data on the most frequent compliance failures it encounters. The issues we see most often among employers we support include the following:
- Failing to assess workers at every pay period - many employers set up auto-enrolment correctly at the outset but then fail to assess new starters or workers whose circumstances change
- Missing contribution payment deadlines - contributions paid late attract interest charges and can trigger enforcement action
- Processing opt-outs incorrectly - accepting an opt-out request before enrolment has taken place, or failing to refund contributions within the required timescale
- Forgetting re-enrolment - the three-year re-enrolment obligation catches many employers off guard, particularly those who set up auto-enrolment several years ago and have since changed payroll systems or staff
- Using a non-qualifying pension scheme - not all pension schemes meet the auto-enrolment qualifying criteria. Using a scheme that does not qualify exposes the employer to a compliance failure regardless of whether contributions are being paid
Practical tip: Treat auto-enrolment as an ongoing payroll function, not a one-time setup. Every new starter, every pay rise, and every three-year anniversary requires action. Building these triggers into your payroll process, or outsourcing payroll to a provider who handles them automatically, is the most reliable way to stay compliant.
What Happens If You Do Not Comply
The Pensions Regulator has significant enforcement powers and uses them. Employers who fail to meet their auto-enrolment duties face a graduated penalty regime.
The Regulator typically issues a compliance notice first, requiring the employer to remedy the failure within a set period. If the employer does not comply, a fixed penalty notice of £400 follows. Further non-compliance triggers escalating penalty notices – daily fines ranging from £50 per day for employers with one to four workers up to £10,000 per day for employers with 500 or more workers.
In serious cases – particularly where an employer has deliberately avoided their duties or has induced workers to opt out – the Regulator can pursue civil or criminal proceedings. These are not simply theoretical consequences. The Regulator publishes details of enforcement action it takes, and the cases include businesses of all sizes.
The cost of non-compliance significantly exceeds the cost of getting it right in the first place.

Frequently Asked Questions
Your duties begin on the employee’s first day of work. You must assess them at that point and at every subsequent pay reference period. If they meet the eligibility criteria, you must enrol them within six weeks of the date they first become eligible.
No. Inducing or encouraging workers to opt out is a criminal offence under the Pensions Act 2008. You can provide factual information about the opt-out process if a worker asks, but you must not suggest, incentivise, or pressure any worker to opt out. The Pensions Regulator takes this prohibition seriously.
A qualifying scheme is one that meets the minimum standards set by the auto-enrolment legislation. These standards relate to the type of scheme, the minimum contribution rates, and the scheme’s governance and administration. NEST (National Employment Savings Trust) is the government-backed qualifying scheme that all employers can use. Many commercial providers also offer qualifying schemes.
If a worker opts out after re-enrolment, the three-year cycle begins again. You must re-enrol them at the next re-enrolment date – you cannot permanently exclude a worker from auto-enrolment simply because they have opted out previously. The obligation to re-enrol every three years is ongoing
Directors who do not have an employment contract are not workers for auto-enrolment purposes and do not need to be enrolled. Directors who do have an employment contract may be workers and may need to be assessed. Where a company has a single director with no other staff, auto-enrolment duties do not apply. We advise on the director position for each client individually.
Conclusion
Auto-enrolment pension compliance is an ongoing, operational obligation – not a one-time administrative exercise. Every pay period requires workforce assessment. Every new starter requires timely enrolment. Every three years requires re-enrolment. And every step requires accurate records.
