How to Increase Workplace Pension Contributions: A Practical Guide

Auto-enrolment minimums are 8% of qualifying earnings (5% from you, 3% from your employer). Tax relief adds roughly 25% to your personal contributions if you're a basic-rate taxpayer. Many employers will match extra contributions up to a stated limit — often buried in your employee handbook.

Check your current contribution rate first

Before you increase anything, confirm what you're paying now. Log into your pension provider's website (the scheme details are on your annual statement or payslip). Most platforms show your percentage and your employer's percentage separately.

Your payslip lists pension deductions as a gross amount (before tax relief is applied at source in a relief-at-source scheme) or a net amount (in a net-pay arrangement, where you get tax relief by paying less income tax). If you're in a net-pay scheme and earning under £12,570, you won't get tax relief on contributions — an often-overlooked quirk that the government has promised to fix but hasn't yet. Check MoneyHelper or GOV.UK for current low-earner relief rules.

Look at your total pot value too. If you've changed jobs and left old pensions behind, consolidating them into your current scheme can simplify tracking, though always compare fund charges and investment options before transferring.

Ask payroll to raise your percentage

The simplest route: email or phone your payroll or HR team and request a higher deduction. Most employers process pension changes monthly, so specify the percentage you want (e.g. "please increase my contribution from 5% to 8% of pensionable salary"). They'll confirm the new deduction amount in writing.

Some companies use an online portal where you adjust your own rate. If your employer offers this, you'll find a slider or input box under 'pension options' or 'benefits'. Changes usually take effect from the next pay period.

Be clear whether you're talking about pensionable salary or total salary. Auto-enrolment uses qualifying earnings (£6,240 to £50,270 for 2024/25 — check GOV.UK for current bands). If you're paid £30,000, qualifying earnings are £30,000 minus £6,240 = £23,760. An 8% contribution on that is £1,900.80 a year. Always confirm the calculation with payroll if the numbers look odd.

Find out if your employer matches extra contributions

Many employers pay more than the 3% minimum if you contribute more. Common structures:

• Tiered matching: employer pays 3% if you pay 5%, but rises to 6% if you pay 8%
• Match up to a cap: employer matches your contribution pound-for-pound up to 5% of salary
• Fixed employer rate: employer always pays 3%, regardless of what you contribute

This information lives in your contract, employee handbook, or pension scheme booklet. If you can't find it, ask HR directly: "Does the company match contributions above the auto-enrolment minimum, and if so, up to what percentage?" Missing out on matched contributions is leaving free money on the table.

If your employer offers matching, prioritise increasing your own contribution to the maximum matched level before putting extra money into a SIPP or ISA. The instant return from employer matching beats almost any investment gain.

Use salary sacrifice if your scheme allows it

Salary sacrifice means you give up part of your salary in exchange for a higher employer pension contribution. Because your official salary falls, you pay less National Insurance (and your employer does too — they sometimes pass that saving back to your pension).

Example: you earn £30,000 and currently contribute 5% (£1,500) through normal payroll deduction. Under salary sacrifice, your salary drops to £28,500, and your employer contributes the £1,500 instead. You save roughly £180 in employee NI; your employer saves about £207 in employer NI. Some firms add their NI saving to your pension pot, boosting the total contribution to around £1,707.

Salary sacrifice can affect means-tested benefits, student loan repayments, or mortgage applications (lenders assess your reduced salary). It also lowers statutory maternity or sick pay, which are based on earnings. Check your circumstances before committing. Many providers — including Nest — support salary sacrifice, but your employer must set it up; you can't do it unilaterally.

Understand how tax relief works on higher contributions

If you're a basic-rate taxpayer (20%), every £100 you contribute costs you £80. The pension provider claims £20 from HMRC and adds it to your pot (relief at source). If you're in a net-pay scheme, you contribute £100 but your taxable pay falls by £100, saving you £20 in tax immediately.

Higher-rate taxpayers (40%) get an extra 20% back through Self Assessment or by calling HMRC to adjust your tax code. Additional-rate taxpayers (45%) get 25% extra. So a £100 personal contribution costs a higher-rate taxpayer £60 after all relief is claimed. Always file a tax return or notify HMRC if you're contributing more and paying higher-rate tax — the extra relief isn't automatic in relief-at-source schemes.

The annual allowance caps total pension contributions (yours, your employer's, and tax relief) at £60,000 for most people. If you've taken money out of a pension flexibly (beyond the 25% tax-free lump sum), the Money Purchase Annual Allowance drops your limit to £10,000. Check current thresholds on GOV.UK if you're contributing substantial sums.

Decide how much extra to contribute

A common rule of thumb: halve your age when you start saving, and contribute that percentage for the rest of your career. Start at 30, aim for 15% total (your contribution plus employer's). Start at 40, aim for 20%. These are rough guides, not rules.

Run the numbers with a workplace pension contribution calculator to see projected pot sizes. The MoneyHelper pension calculator lets you model different contribution rates and retirement ages. Remember that your state pension (currently £11,502.40 a year for a full new state pension) will top up your workplace pension, so factor that in when estimating retirement income needs.

Prioritise your workplace pension up to the employer match limit, then consider whether extra contributions or a SIPP make sense. SIPPs offer wider investment choice but usually higher charges. If your workplace scheme has low fees and decent funds, increasing contributions there is often simpler than managing multiple pots.

Make one-off payments if regular increases aren't feasible

Most workplace schemes accept one-off contributions by bank transfer or cheque. Contact your pension provider for their payment reference and sort code. One-off payments still get tax relief — the provider claims basic-rate relief automatically if it's a relief-at-source scheme, and you claim higher-rate relief through Self Assessment.

Useful for bonuses, inheritance, or windfalls. Spreading a lump sum over several tax years can keep you under the annual allowance if the amount is large. For example, £100,000 paid in one go might trigger an annual allowance charge; £60,000 this year and £40,000 next year stays within limits (subject to carry-forward rules — check GOV.UK or speak to an adviser if sums are substantial).

Some employers let you redirect part of your bonus into your pension via payroll, which can be more tax-efficient than taking it as cash and making a personal contribution afterward.

Review contributions annually

Set a calendar reminder each April (new tax year) to check your percentage. If you've had a pay rise, your cash contribution rises automatically, but your percentage stays the same — so a 5% contribution on £25,000 becomes 5% on £27,000 without you doing anything.

If you can afford it, increase your percentage by 1% each year. The impact on take-home pay is smaller than you'd think: a 1% rise on £30,000 qualifying earnings is about £15 a month after tax relief. Over a career, those incremental rises compound significantly.

Also review your investment funds. Most workplace pensions default you into a lifestyle or target-date fund, which automatically shifts from shares to bonds as you near retirement. If you're decades away, you might prefer 100% equities for growth. If you're close to retirement, check the fund hasn't left you overexposed to stock market swings. Your provider's website usually lets you switch funds for free.

What if you're already opted out?

If you previously opted out, you can opt back in at any time by telling your employer. They must re-enrol you within a set period (usually a month). You'll start on the minimum contributions unless you request a higher rate from day one.

Your employer must automatically re-enrol you every three years if you're still opted out and meet the eligibility criteria (aged 22 to state pension age, earning over £10,000). You can opt out again, but you'll miss years of compound growth and employer contributions. The earlier you start, the less you need to contribute overall — starting at 25 requires roughly half the monthly input of starting at 40 to reach the same pot size at 68.
