Beyond the minimum: growing your workplace pension

When you've spent years in a UK workplace pension through automatic enrolment, you likely have a solid foundation—but most people are sitting on far more growth potential than they realise. By exploring employer matching, using salary sacrifice, tracking down forgotten pots, and reviewing where your money is actually invested, you can transform several modest pots into serious long-term wealth without dramatic lifestyle changes.

Employer matching: claiming free money

Many employers offer matched contributions on top of the mandatory 3% minimum—and it is genuinely free money that most employees never claim. When an employer offers a match, they will contribute more to your pension if you increase your own contributions up to a limit. For example, an employer might match 4% of your salary if you also contribute 4%. That is an instant doubling of pension growth on the portion you match, plus the power of compound interest over decades.

The catch is that the match has a ceiling. Your employer won't usually match contributions above a stated percentage—typically 4% to 7%—so contributing more than that threshold brings no additional employer cash. However, you may still want to contribute beyond the match for your own retirement security, especially given that concerns exist about whether the statutory 8% minimum is enough.

The easiest step is to check with your HR or payroll department what your company actually offers. Request a copy of your pension scheme documentation or employee benefits summary. If a match exists and you are not taking advantage of it, adjusting your contribution upward is one of the fastest ways to boost your retirement pot. Even a 1% or 2% increase toward a match threshold can mean tens of thousands of extra pounds over a career.

Salary sacrifice: save on National Insurance as well

Most workplace pensions attract income tax relief automatically, but regular contributions do not reduce your National Insurance (NI). Salary sacrifice (sometimes called salary exchange) changes this by letting you exchange a portion of your salary for an extra employer pension contribution, cutting both income tax and National Insurance from your paycheck.

Here is how it works in practice. Instead of receiving your full salary and then contributing from your net pay, you formally agree to reduce your salary, and your employer pays the equivalent directly into your pension as an employer contribution. Because your recorded salary is lower, you pay no National Insurance on that amount. A basic-rate taxpayer and employee earning £30,000 might save around 8% in NI on contributions through salary sacrifice; employers save 15% on their own NI for the same amount.

The maths are compelling. If you earn £30,000 and sacrifice £1,500 (5%) into your pension by salary sacrifice, you avoid paying National Insurance on that £1,500. At an 8% NI rate, that is roughly £120 saved in a single year—or £600 over five years. Over a career, the compound benefit is substantial.

An important 2029 change

From 6 April 2029, the tax and NI benefits of salary sacrifice will be capped. The National Insurance exemption will apply only to the first £2,000 of salary-sacrificed pension contributions per year. Anything above £2,000 will attract employee and employer National Insurance. For most people this makes little practical difference, but high earners and those planning large additional contributions should be aware of the threshold and consider timing their increased contributions accordingly.

Ask your employer whether they operate a salary sacrifice scheme for pensions. If they do, you can enrol and set your contribution level. If they do not, you may still be able to make regular contributions from your net salary, which will attract income tax relief (though not NI relief). In either case, speak to payroll about the process and any paperwork you need to sign.

Finding lost pots with the Pension Tracing Service

Most people change jobs multiple times over a career, and each job typically means a new pension pot. Across the UK, there are an estimated 3.3 million lost or forgotten pension pots worth approximately £26.6 billion in total—an average of around £9,500 per pot. Because these pensions keep growing in the background, tracing them and consolidating them with your current plan can mean a welcome surprise in your retirement accounts.

The government runs a free Pension Tracing Service at gov.uk/find-pension-contact-details. You can search online or phone 0800 731 0193. You will need basic information: your previous employer's name (or the pension provider name if you have it), your date of birth, your National Insurance number, and the approximate dates you worked or paid into the scheme. The service will search its database and provide you with contact details for any pension provider it finds. You then contact that provider directly to request a valuation and decide whether to consolidate the pot into your current pension.

Consolidation—moving old pots into one modern scheme—can simplify your retirement planning and sometimes reduces fees if your old schemes are expensive. However, some older pensions carry valuable guarantees or benefits. Before consolidating, check the terms of the old scheme or speak to a financial adviser to ensure you are not giving up something valuable. The adviser can also help trace pots you cannot locate yourself.

Check where your money is actually invested

When you are auto-enrolled into a workplace pension, your contributions go into a default investment fund chosen by your employer. Most people never question this. In fact, research shows that roughly 90% of members stay invested in the default fund for their entire working life—even though the default may not suit their circumstances, age, or risk tolerance.

Default funds are designed to suit a broad range of workers and balance growth potential with risk management. Many use a 'target date' or 'lifestyle' strategy, automatically reducing investment risk as you approach retirement because there is less time to recover from market downturns. However, default funds vary significantly. Some invest heavily in shares (which carry higher growth potential and higher volatility), while others hold a mix of shares, bonds, and cash.

Log into your pension provider's online portal or ask your employer for your latest pension statement. Find out which fund your money is in, what assets it holds (shares, bonds, property, cash), and what fees you are paying. If the default does not match your goals—perhaps it is too cautious if you are in your 20s and have decades until retirement, or too aggressive if you are five years from retirement—your pension provider should offer alternative ready-made funds.

Your options if the default does not suit you

• Switch to an alternative lifestyle or ready-made portfolio offered by your provider, designed for different risk profiles or retirement dates.
• Choose from a 'self-select' range of individual funds if your scheme allows it, giving you full control over which assets you hold.
• Consult a financial adviser before making changes, especially if you have substantial savings or approaching retirement, to ensure your choice aligns with your long-term goals and risk appetite.

The key insight is that investment choices do matter. A younger employee with a cautious default fund might be receiving lower returns than they could tolerate, whereas someone within a decade of retirement in an aggressive growth fund faces unnecessary risk. Taking an hour to review and, if needed, rebalance your investment can compound into meaningful gains or losses over the years ahead.

Pulling it all together: a simple action plan

Growing your workplace pension beyond the minimum requires no heroic lifestyle sacrifice. Here is a practical checklist you can complete over the next month:

1. Contact your HR or payroll department and ask whether your employer offers matched contributions. If yes, calculate how much you would need to contribute to claim the full match and explore raising your contribution at your next pay review.
2. Ask whether your employer operates a salary sacrifice pension scheme. If yes, understand the details, confirm it suits your circumstances, and enrol if it makes sense.
3. Visit gov.uk/find-pension-contact-details and use the Pension Tracing Service to find any lost pots from previous jobs. Write down each one you find and request a valuation.
4. Log into your current pension portal or request a statement. Confirm which fund you are in, review its investment approach, and decide whether it matches your age and retirement timeline. If not, speak to your provider about switching to a more suitable option.
5. Once you have consolidated any lost pots and optimised your contributions, set a reminder to review your pension annually. Circumstances change, contribution limits rise, and your investment strategy may need tweaking as you move closer to retirement.

The compounding power of pensions works best when left undisturbed over decades, but that does not mean passive neglect. A few deliberate choices now—maximising employer matching, using salary sacrifice, recovering forgotten pots, and investing appropriately for your age—can easily add tens of thousands of pounds to your retirement by the time you claim it. For expats and non-British residents settling in the UK, a robust workplace pension is one of the most tax-efficient and accessible wealth-building tools available.
