UK Average Net Worth and Household Wealth in 2018
In 2018, the Office for National Statistics reported that the average (mean) net worth of UK households was about £473,000, while the median net worth was around £125,000, reflecting high wealth concentration at the top. The ONS Wealth and Assets Survey showed that total UK household wealth reached roughly £11.1 trillion by mid-2018, driven mainly by property and pension entitlements, with the top 10% of households owning about 44% of all wealth. For context on global billionaires, the Forbes Billionaires List 2018 tracked the world's richest individuals and their net worths, and the richest people in the UK were covered in related rich lists and financial analyses Forbes Billionaires List 2018.
ONS data highlighted that property made up the largest share of UK household wealth in 2018, followed by private pensions, while financial assets such as stocks, shares, and savings formed a smaller but growing slice. Net worth is calculated as total assets minus liabilities, so the headline averages depend heavily on housing equity and pension values, and they can differ sharply from the typical experience of younger households or renters. The same survey also showed that the bottom half of households held only about 9% of total wealth, underscoring the gap between average and median figures ONS Wealth and Assets Survey.
Wealth Distribution and Inequality in the UK in 2018
In 2018, the wealthiest 10% of UK households had average net worth above £1.3 million, while the poorest 10% had average net worth close to zero or slightly negative once debts were counted, according to ONS analysis. Regional differences were pronounced, with households in London and the South East typically showing higher net worth than those in the North East, Wales, or Scotland, partly due to property values and pension savings patterns. The Gini coefficient for household wealth in the UK remained high, indicating substantial inequality, and the ONS noted that wealth concentration had been rising over the preceding decades ONS Wealth and Assets Survey.
Wealth inequality in 2018 was also visible in the composition of assets, with the top decile holding a much larger share of financial wealth, business assets, and property than lower groups, while many lower-wealth households relied mainly on pension entitlements and modest savings. The Financial Conduct Authority and related bodies tracked these trends to inform policy on savings, pensions, and financial inclusion, noting that a significant share of households had little or no financial resilience. Internationally, the UK's wealth distribution compared with other developed economies, and organizations such as the World Inequality Database and related research groups published analyses of how UK figures stacked up against global averages World Inequality Database.
