The number of people celebrating their 100th birthday in the UK is on the rise. As life expectancy continues to increase, it is more important than ever to plan financially for a 100-year life.

According to the Office for National Statistics (ONS), there were 16,600 centenarians in 2024 – double the number in 2004 (21 October 2025).

Among those marking the milestone this year is the renowned natural historian Sir David Attenborough. The broadcaster turned 100 on 8 May, and he continues to share his passion for nature with the world.

Attenborough shows that entering later life doesn’t have to mean taking a step back. You could still embrace new experiences and create a life you love.

However, planning for a 100-year life often raises important questions about how to arrange your finances to secure the life you want, including how to ensure you have “enough” and what strategies are appropriate for you.

This guide explores some of the steps you might take to plan for a 100-year life.
