Pension Auto-Enrolment Re-Enrolment 2026 Cycle

Quick answer

Auto-enrolment is the duty introduced under the Pensions Act 2008 that obliges UK employers to put eligible workers into a qualifying workplace pension scheme and pay minimum contributions. Workers can opt out, but every three years the employer must repeat the process — re-enrolment — to give former opt-outs a fresh chance to stay in.

The 2026 re-enrolment cycle catches employers whose previous staging or re-enrolment date fell in 2023. The Pensions Regulator publishes a re-enrolment date tool, but in practice it is the employer's choice within a window:

• Earliest date: three months before the third anniversary of the previous re-enrolment date.
• Latest date: three months after.
• Declaration of Compliance: within five months of the chosen date.

Who must be re-enrolled

A worker is an eligible jobholder for re-enrolment if on the chosen date they:

1. Are aged 22 or over but under State Pension age.
2. Have qualifying earnings over £10,000 per year (£833 per month or £192 per week).
3. Previously opted out, ceased active membership, or left the scheme more than 12 months ago.
4. Are not in an active qualifying scheme at the re-enrolment date.

Workers who opted out within the 12 months before the re-enrolment date are excluded for this cycle. They will be picked up at the next cycle in 2029.

You may also choose to re-enrol staff who left or opted out within the past 12 months at your discretion — but it is optional, not a duty.

Employer duties — the 5-step process

1. Choose the re-enrolment date within the 6-month window.
2. Assess the workforce on that date to identify eligible jobholders previously opted out.
3. Put them into the scheme — payroll starts deducting employee contributions from the next pay reference period.
4. Write to each affected worker within 6 weeks, explaining their re-enrolment and right to opt out.
5. Complete the Declaration of Compliance with the Pensions Regulator within 5 months.

Failure at any step triggers a Pensions Regulator inspection. Penalties begin with a £400 fixed notice and escalate to daily fines of £50 (1–4 staff), rising to £10,000 (500+ staff).

Minimum contribution rates 2025/26

The statutory minimum is 8% of qualifying earnings — the band between £6,240 and £50,270 in 2025/26.

The £25,000 employee pays £750 net per year (£62.50 per month) to get £1,501 in the pension. That is a 100% government-and-employer match before any investment growth.

Many large employers pay above the statutory minimum — typically 5% employer / 3% employee, or matched up to 8%/8%. See our SIPP vs workplace pension post for how to evaluate the upgrade.

Worked example 1 — £30,000 employee re-enrolled in 2026

Sarah opted out of her workplace pension in 2023 when she joined the company. Her 2026 re-enrolment date is 1 July 2026. She is 28, earning £30,000.

• Qualifying earnings: £30,000 – £6,240 = £23,760.
• Employer 3% contribution: £713 per year.
• Employee 4% net contribution: £950 per year (£79 per month).
• Tax relief 1% on the gross: £238.
• Total pension pot increase year 1: £1,901.

If Sarah stays in for 30 years to age 58 with the same earnings (real-terms) and 5% annual investment growth, the pot reaches approximately £126,000 in today's money. If she opts out again, she keeps £79 per month of net pay but forfeits the full £1,901 of annual saving.

That is the trade-off: £950 of her own net pay buys £1,901 of pension contribution every year — a 100% return before growth. The workplace pension opt-out 30-year cost post walks through the lifetime cost in more detail.

Worked example 2 — £55,000 employee re-enrolled

Tom earns £55,000 and opted out in 2023. He is 45 and re-enrolled in October 2026.

• Qualifying earnings: capped at £50,270 – £6,240 = £44,030.
• Employer 3%: £1,321 per year.
• Employee 4% net: £1,761 per year (about £147 per month).
• Tax relief: at higher rate, the £441 gross relief is split — 20% at source (£88 added to the pot) and an extra 20% claimed via Self Assessment or coding adjustment (£88 cash back).
• Net cost to Tom: about £1,673 per year for £3,522 added to the pension.

If Tom keeps the contributions for 20 years to age 65 at 5% growth, the pot from re-enrolment alone reaches roughly £117,000. Higher-rate relief makes the deal even better than the headline 8% suggests.

How to opt out — and why most should not

Workers can opt out within one month of being re-enrolled by submitting an opt-out notice. The employer must:

• Refund employee contributions taken during the opt-out window.
• Stop deducting from the next pay run.
• Record the opt-out date for future re-enrolment cycles.

But opting out is rarely the right call:

1. You lose the employer 3% — that is unrecoverable cash.
2. You lose the 1% tax relief on the gross.
3. You lose decades of compounded growth.

A £25,000 employee who opts out for an entire 40-year career loses roughly £126,000 of pension wealth in today's money. The monthly "saving" of £63 of net pay buys nothing comparable.

Employer admin checklist

Within 6 weeks of the re-enrolment date, the employer must send each affected worker a re-enrolment letter covering:

• Their re-enrolment date.
• The scheme they have been enrolled into.
• Contribution rates and how the deduction works.
• Their right to opt out and how.
• The Pensions Regulator's contact details.

Within 5 months, file the Declaration of Compliance online — even if no workers were eligible (a "nil declaration").

Common employer mistakes:

• Forgetting the 6-month window: re-enrolment is mandatory regardless of whether the employer remembers.
• Picking the same date as the staging date: allowed but inflexible; payroll usually prefers month-end.
• Failing to re-assess earnings: someone who was below £10,000 in 2023 may now be above.

What if I have moved jobs since 2023?

Re-enrolment is an employer duty, not a worker duty. If you opted out at Employer A in 2023 and moved to Employer B in 2024 — and joined B's pension — there is no re-enrolment event for you in 2026 from Employer A. Your live pension at Employer B continues unaffected.

If you opted out of both employers, B will run its own 3-yearly cycle starting from its staging or last re-enrolment date.

Self-employed — what about me?

Auto-enrolment does not cover the self-employed. To save into a pension you must contribute personally to a SIPP or stakeholder pension and claim 20%–45% relief through Self Assessment. See our self-employed pension comparison guide for the trade-offs against a workplace scheme.
