A workplace pension is a pension scheme arranged by an employer to provide retirement income for its employees. Since the introduction of automatic enrolment in 2012, every UK employer must enrol eligible workers into a qualifying pension scheme and make contributions.
Workplace pensions are a core obligation for any business with staff, whether you are a limited company with hundreds of employees or a sole trader with a single worker.
Automatic Enrolment
Under the Pensions Act 2008, employers must automatically enrol workers who meet certain criteria into a qualifying pension scheme. This is enforced by The Pensions Regulator (TPR).
Who Must Be Enrolled?
| Criterion | Requirement |
|---|---|
| Age | Between 22 and State Pension age |
| Earnings | Earning above the annual earnings trigger |
| Working in the UK | Must be ordinarily working in the UK |
Workers who meet all three criteria are eligible jobholders and must be automatically enrolled.
Workers who do not meet all the criteria can still opt in:
- Non-eligible jobholders (aged 16-21 or State Pension age to 74, earning above the earnings trigger; or aged 16-74, earning between the lower qualifying earnings threshold and the trigger) can opt in, and the employer must contribute
- Entitled workers (earning below the lower threshold) can opt in, but the employer does not have to contribute
Opt-Out Rights
Workers can choose to opt out of the pension scheme within one month of being enrolled. If they do, any contributions already made are refunded. However, employers must re-enrol opted-out workers every three years.
Minimum Contribution Rates
The law sets minimum contribution levels based on qualifying earnings (the band of earnings between the lower and upper thresholds):
| Contributor | Minimum Contribution |
|---|---|
| Employer | 3% of qualifying earnings |
| Employee | 5% of qualifying earnings (including tax relief) |
| Total | 8% of qualifying earnings |
The Department for Work and Pensions reviews the earnings trigger and the qualifying earnings band every year, and GOV.UK publishes the current figures. Employers can choose to contribute more than the minimum. Many use enhanced pension contributions as a benefit to attract and retain staff.
Certification
Some employers use a certification method, basing contributions on total earnings or a set portion of pay rather than qualifying earnings. This simplifies payroll but must still meet or exceed the minimum overall contribution level.
Types of Workplace Pension
Defined Contribution (DC)
The most common type for private-sector employers. Both employer and employee contribute to an individual pension pot, which is invested. The retirement income depends on:
- How much has been contributed
- How well the investments perform
- How the pot is accessed at retirement (annuity, drawdown, or lump sum)
The risk sits with the employee — there is no guaranteed income level.
Defined Benefit (DB)
Also known as final salary or career average schemes, these promise a specific retirement income based on salary and years of service. The risk sits with the employer, who must ensure the fund can meet its obligations.
DB schemes are increasingly rare in the private sector due to their cost and risk, but remain common in the public sector (e.g. NHS, civil service, teachers, local government).
Multi-Employer (Master Trust) Schemes
Smaller employers often use a master trust — a large, multi-employer defined contribution scheme run by a professional provider. The largest in the UK is NEST (National Employment Savings Trust), set up by the government specifically for auto-enrolment. Others include The People’s Pension, NOW: Pensions, and Smart Pension.
Employer Duties
As an employer, your obligations include:
- Assess your workforce — Determine which workers are eligible, non-eligible, or entitled
- Choose a pension scheme — Select a qualifying scheme (or use NEST if you cannot find an alternative)
- Enrol eligible workers — Automatically enrol them from their start date (or staging date for new employers)
- Make contributions — Pay at least the minimum employer contribution on time
- Manage opt-outs and joiners — Process opt-out requests within the deadline and handle new starters
- Re-enrol every 3 years — Re-assess and re-enrol any workers who previously opted out
- Keep records — Maintain records for 6 years (4 years for opt-out records)
- Complete a Declaration of Compliance — Submit to The Pensions Regulator within 5 months of your duties start date
Penalties for Non-Compliance
The Pensions Regulator can issue:
- Fixed penalty notices — £400 for failure to comply
- Escalating penalty notices — £50 to £10,000 per day depending on the number of employees, until you comply
- Criminal prosecution — In serious cases of wilful non-compliance
Costs and Accounting Treatment
Employer pension contributions are:
- An allowable expense for Corporation Tax or income tax purposes
- Subject to employer National Insurance Contributions exemption (pension contributions are not subject to employer NIC, unlike salary)
- Recorded as an expense in the profit and loss account
On the balance sheet, any outstanding pension contributions at the year-end appear as a current liability (amounts owed but not yet paid).
For defined benefit schemes, the accounting treatment is more complex, involving actuarial valuations and potentially significant assets or liabilities on the balance sheet.
Accurate accounting for pension contributions is essential for both compliance and financial reporting.
Salary Sacrifice
Many employers offer salary sacrifice (also called salary exchange) arrangements for pension contributions. The employee agrees to a lower gross salary, and the employer pays the difference into the pension. Benefits include:
- Employee saves on National Insurance (and income tax relief is automatic)
- Employer saves on employer National Insurance
- The employer NI saving can be passed into the pension, boosting the employee’s pot
- The arrangement must be genuinely contractual (not just a payroll mechanism)
Choosing a Pension Provider
When selecting a workplace pension scheme, consider:
- Charges — Look at the annual management charge (AMC), which is capped at 0.75% for default funds in qualifying auto-enrolment schemes
- Investment options — Range of funds available, including ESG and ethical options
- Ease of administration — Integration with your payroll software
- Employee experience — Online portals, apps, and customer support quality
- Reputation and governance — Master trusts must be authorised by The Pensions Regulator
Workplace Pension vs Personal Pension
| Feature | Workplace Pension | Personal Pension |
|---|---|---|
| Set up by | Employer | Individual |
| Employer contributions | Yes (minimum 3%) | Not usually |
| Auto-enrolment | Yes | No |
| Tax relief | Automatic via payroll | Claimed from HMRC or via self-assessment |
| Charges | Often lower (group buying power) | Varies widely |
| Portability | Moves with the employee (or can be transferred) | Stays with the individual |
Workers can have both a workplace pension and a personal pension (such as a SIPP), subject to the overall annual allowance for tax-relieved contributions (a fixed annual limit or 100% of earnings, whichever is lower; the limit can be tapered for very high earners).
A workplace pension supplements the State Pension, which is funded through National Insurance contributions and provides a basic level of retirement income.
