With modern platforms and low-cost index funds, getting started investing has never been easier. Here's everything you need to know.
Why Invest Beyond Just Saving
With inflation at 2.8%, real returns on cash savings are only ~1.7%. A global index fund returning a historical 8%/year turns £10,000 into £21,910 in real terms over 20 years — versus £13,970 in cash.
