I still remember the afternoon my cousin called—half ecstatic, half terrified—having just sold her tech start-up for what felt like a life-changing sum. We gushed over celebratory pints, but beneath her grin was that familiar flutter of panic:   

“Where on earth do I even start?” It’s a question that haunts many of us who stumble on unexpected riches. 

The Pause That Saves 

It might sound laughably obvious, but don’t sprint to the shops—or heaven forbid, scribble cheques in the heat of the moment.  

That first hour (or day, or week) is precious. Stash the numbers somewhere safe, then step back. Yes, let yourself daydream—European road trips, a little side cottage in Devon, maybe even that bespoke suit you’ve always hankered after.  

But scribble those ideas on paper before you give into impulse. You’ll thank yourself when impulse buys aren’t draining your newfound nest egg.  

Charting a Course for Your Cash 

Now comes the fun part: setting out a plan. It doesn’t require a doctorate in finance. In fact, the simpler, the stronger.  

List your “must-haves.” Identify what truly matters to you—security, creativity, fun, or perhaps a mix of all three. And give everything a rough deadline. A short-term splurge shouldn’t bust your long-game goals. 

This sketch becomes the backbone of every decision.  

Even if it’s half-formed at first, it helps you steer clear of decisions you’ll regret when reality bites. 

Assembling a Dream Team 

No one sails solo across uncharted waters. According to Lottoland’s article on managing unexpected windfalls, you must reach out to: 

  • A regulated financial planner who gets UK markets and all those ISA rules.  
  • A chartered accountant to minimise your tax bill (legally, of course).  
  • A specialist solicitor for wills, trusts and estate planning.  

Friends might suggest “someone they know,” but go for credentials—look for firms regulated by the Financial Conduct Authority or members of the Chartered Institute of Taxation. Your future self will breathe easier.  

Invest for Growth, Shield from Risk 

You’ve heard “don’t put all your eggs in one basket,” but how many of us actually diversify?  

Here’s a balanced mindset

  • Guard a core nest egg in low-volatility bonds or cash-ISAs. 
  • Spread another chunk across diversified index trackers or ethical funds. 
  • Tuck away a small slice for something that sparks joy—artwork, classic car restoration, a start-up you believe in. 

Quarterly check-ins are fine. Annual reviews are great. The key is staying loosely in control—so you’re never left clutching a stress ball on 5% dips. 

Keep Your Feet on the Ground 

Between meetings and market charts, don’t lose sight of the person you were before all the zeros appeared.  

Life’s about those Sunday roasts with family, impromptu pub quizzes, the odd rainy ramble along the Thames Path. Revisiting your plan—nudging, tossing out, recalibrating—isn’t failure; it’s proof you’re alive to new possibilities. 

After all, wealth is a tool, not a trophy. You want it to amplify purpose, not overshadow it.
