The legal minimum
Under auto-enrolment, your employer must contribute at least 3% of your qualifying earnings to your workplace pension, as part of an 8% total minimum contribution (the rest coming from you and tax relief). This is a floor, not a cap — many employers offer more.
Checking what your employer actually offers
Your contract, staff handbook, or HR team will confirm your scheme's exact contribution structure. Some employers simply pay the legal minimum; others offer a flat, more generous rate (say, 5% or 6% regardless of what you pay); and some operate "matching" schemes where they increase their contribution as you increase yours, up to a cap.
Salary sacrifice
Many employers offer salary sacrifice (sometimes called "SMART pensions"), where you agree to a lower salary in exchange for a larger employer pension contribution of the same value. Because this reduces your salary on paper, it can also reduce the National Insurance both you and your employer pay — and some employers pass some or all of their own NI saving back into your pension too, effectively boosting your contribution further at no extra cost to you.
Why it's worth checking annually
Contribution matching structures change, employers merge schemes, and your own pay rises can shift you between contribution bands. A five-minute check with HR or your payslip once a year — confirming you're getting the maximum match your employer offers — is one of the highest-value financial admin tasks available, since unclaimed matching is effectively unclaimed salary.
Key takeaways
- 3% of qualifying earnings is the legal minimum employer contribution, not the norm everywhere.
- Matching schemes mean increasing your own contribution can increase your employer's too.
- Salary sacrifice can boost your pension via National Insurance savings, sometimes shared by your employer.
- Check you're getting your employer's maximum match at least once a year.
