How auto‑enrolment affects employer clients

Auto‑enrolment, which was introduced in 2012, requires employers to enrol eligible employees into a workplace pension automatically. For advisers, this means supporting employer clients to meet their legal duties  from enrolment through to ongoing contributions.

The benefits for employers and employees

Auto‑enrolment is designed to support retirement saving, but it can also deliver real value for employers. Well‑run schemes can strengthen employer branding, support recruitment and retention, and improve employee wellbeing.

As well as this, better financial security can reduce stress and help sustain performance.

Aviva supports advisers with clear communications and member information, helping employers keep employees engaged and informed about their pension benefits.

Which employees must be auto‑enrolled

Employers must auto‑enrol employees who meet the following criteria:

  • between 22 and the State Pension age
  • earning over £10,000 a year
  • working in the UK

Employees who don’t meet the eligibility criteria can still opt in. Where they do, employers must make at least the minimum required contribution.

Understanding the cost for employers

The minimum total contribution is 8% of qualifying earnings, of which employers must contribute 3%. The other 5% can be made up of employee contributions or further employer contributions, which can be raised via salary sacrifice, though that has to be voluntary.

Advisers should also help employers factor in set‑up costs, professional advice, payroll processes and ongoing provider charges.

 

Key actions and when they apply

A workplace pension must be in place from the employer’s duties start date. Advisers typically recommend planning at least two months in advance of this.

The first step is selecting a pension provider and understanding the level of auto‑enrolment support they offer.

Employers must assess eligibility, confirm contribution levels and complete enrolment. With Aviva, this can be managed through a simple online file upload.

Once enrolment is complete, statutory communications must be issued and a declaration of compliance submitted.

Ongoing duties after implementation

Employers must continue making contributions, assess eligibility each pay period and process opt‑outs within statutory windows.

Employees may ask to stop their contributions but employers can't encourage or prompt this. Requests must be recorded, and affected employees included at the next re-enrolment window.

Accurate record‑keeping is essential, supporting 18‑month recertification and three‑year re‑enrolment cycles.

What happens if deadlines are missed

Maintaining compliance is critical. Missed deadlines can lead to significant penalties from The Pensions Regulator
