If an unexpected lump sum lands in your bank account, you might be tempted to splash out and treat yourself. However, using a windfall effectively could create long-term prosperity.
There are plenty of reasons why you might suddenly receive a cash injection. Perhaps you’ve received a bonus from work or inherited assets. Whatever the reason, before you start making plans, read on to find out how you might use it to improve your long-term financial security.
Favouring savings could mean UK adults miss out on long-term growth
A February 2025 study from Aegon asked UK adults how they’d use an unexpected £5,000 bonus. Encouragingly, 70% would prefer to save for the future or pay off existing debt than spend it on themselves.
However, many would miss out on long-term growth opportunities as they favoured holding the money in cash – 27% would deposit it in a savings account and 16% would use a Cash ISA. In contrast, just 9% would invest in stocks and shares and 5% would invest through their pension.
While cash can seem like the “safe” option, the interest rate is likely to be lower than potential investment returns. So, while intentions might be good, they could be missing out on an opportunity for long-term growth.
Investing isn’t always the right option if you’ve received a windfall but it’s important to weigh up the pros and cons. Here are six useful steps that could help you identify how to use an unexpected cash injection in a way that reflects your goals.
1. Set out your financial goals
You can’t make a decision that reflects your goals if you haven’t defined what they are.
So, before you start thinking about how to use the money, answer these questions: What are your main financial goals, and when do you want to achieve them?
Your answer can provide direction for the decisions you make next. For example, if you said you wanted “to create a nest egg to give my child in five years”, the most effective way to use the money would be different than if your answer was “to retire in 20 years”.
2. Assess your current finances
A windfall might seem separate from your day-to-day finances. Yet, taking the time to understand your current financial position and how the additional money could be used to support your existing financial plan is likely to be valuable.
For instance, the Aegon research found 12% of people would opt to pay off debt.
Paying off debt may make financial sense and have a positive effect on your overall wellbeing – many people feel relief and a sense of achievement when their mortgage is paid off.
In addition, lowering your regular outgoings might provide you with greater freedom. Perhaps you could reduce your working hours or change your role as a result.
3. Review your financial safety net
While part of your wider financial plan, it’s worth paying particular attention to your financial safety net when reviewing your current position.
You may hope to never need your emergency fund, but, should something unexpected happen, a financial safety net is invaluable.
A common rule of thumb is to have six months of expenses in an easily accessible account that you could use in an emergency, from a roof repair to needing to take time off work due to an illness. Going through your financial commitments could help you set an emergency fund target that’s right for you.
You may also want to consider financial protection. Several types of protection would pay out either a lump sum or regular income when the conditions are met. For example, income protection would normally provide you with a portion of your salary if you need to take time off work because you’re ill or injured.
4. Consider if investing is right for your goals
When you’ve received a windfall, one important decision is whether to save or invest the money.
Usually, a savings account makes sense if you’re goal is within the next five years or you might need access to the money at short notice, such as your emergency fund.
On the other hand, if you want to build long-term prosperity, investing might be the right option for you.
It’s not possible to guarantee investment returns. However, markets have, historically, delivered returns over a long-term time frame. So, if you aim to turn a windfall into wealth that could support long-term goals, investing may help you get more out of your money.
5. Add money to your pension
If you decide investing is right for you, don’t overlook your pension.
A pension provides a tax-efficient way to invest for your retirement. Tax relief provides an instant boost to your contributions, and the potential to benefit from decades of compound returns might turn an initial lump sum into a way to create a comfortable retirement.
However, you can’t usually access the money in your pension until you turn 55 (rising to 57 in 2028). So, it’s important to understand your goals and time frame before you boost your retirement pot.
6. Seek professional advice
Working with a regulated financial planner gives you a chance to really consider what you want to get out of the windfall, and how you might achieve that. As well as creating an initial blueprint, ongoing financial advice could help ensure you remain on track and that your plan is updated to reflect changes in your goals or circumstances.

A pension is a long-term investment not normally accessible until 55 (57 from April 2028). The fund value may fluctuate and can go down, which would have an impact on the level of pension benefits available. Past performance is not a reliable indicator of future performance.
The tax implications of pension withdrawals will be based on your individual circumstances. Thresholds, percentage rates, and tax legislation may change in subsequent Finance Acts.
Note that financial protection plans typically have no cash in value at any time and cover will cease at the end of the term. If premiums stop, then cover will lapse.
Cover is subject to terms and conditions and may have exclusions. Definitions of illnesses vary from product provider and will be explained within the policy documentation.
