Under auto-enrolment, eligible employees are automatically signed up to a workplace pension, and most keep saving. But opting out is allowed, and some people do it to boost their take-home pay. Before opting out, it's worth understanding exactly what you'd be giving up — because it's usually more than just your own contribution.
What opting out actually stops
If you opt out, three things typically stop:
- Your own employee contribution (commonly around 5% of qualifying earnings)
- Your employer's contribution (commonly around 3% of qualifying earnings, though some employers pay more)
- The government's contribution in the form of tax relief added to your own contribution
The employer and tax-relief portions are, in effect, free money you'd be walking away from. Losing the employer contribution alone is usually a bigger cost than the tax and NI saved by not contributing yourself.
Worked example
| Staying enrolled | Opting out | |
|---|---|---|
| Salary (qualifying earnings portion) | £25,000 | £25,000 |
| Employee contribution (5%, net cost after relief ~4%) | ~£1,000/yr into pension | £0 |
| Employer contribution (3%) | £750/yr into pension | £0 — forfeited |
| Extra take-home pay from opting out | — | Roughly £1,000/yr (the net cost of your own contribution) |
| Total pension saving lost per year | — | ~£1,750 |
In other words, for roughly £1,000 more in your pocket each year, you'd give up £1,750 going into your pension — and lose out on decades of investment growth on top.
When opting out might make sense
- You genuinely cannot afford the reduction in take-home pay and have higher-priority debts (such as high-interest credit card debt) to clear first
- You're very close to certain lifetime pension or lump sum limits and further contributions would create a tax charge
- You already have adequate pension provision elsewhere and have a specific short-term reason to maximise cash flow
Even then, it's often better to reduce contributions to the statutory minimum rather than opt out entirely where possible, so you keep the employer match.
Re-enrolment
Employers must run a re-enrolment process roughly every three years, putting eligible staff who previously opted out back into the pension automatically (as long as they still meet the eligibility criteria). You can opt out again each time if you still want to, but this cycle means an opt-out isn't necessarily permanent unless you keep actively opting out.
Common mistakes
- Opting out without realising the employer contribution is forfeited too, not just your own
- Opting out instead of simply asking to contribute the statutory minimum, which still keeps the employer match
- Not reconsidering the decision at each re-enrolment point, even when circumstances have improved
- Confusing "opting out" (a formal process with a refund of contributions made so far, usually within the first month) with "ceasing active membership" later on, which doesn't refund past contributions
What to do next
Before opting out, check exactly what your specific employer contributes and whether there's a middle ground, like reducing your own contribution rate rather than leaving the scheme entirely. If cash flow is the real problem, it may be worth speaking to a free debt or budgeting service via MoneyHelper first.
