London Flat Prices Fall 12% in Six Months, Says Office for National Statistics
London’s residential property market has experienced a steep decline, with average flat prices dropping 12% over six months, according to the Office for National Statistics (ONS). The data, released on October 20, 2023, marks the largest quarterly fall since 2009, reflecting broader challenges in the UK’s housing sector. “This is a significant shift driven by rising borrowing costs and reduced buyer demand,” said a spokesperson for the ONS.
What’s Driving the Decline?
The sharp drop in London flat prices aligns with a broader slowdown in the UK property market. The Bank of England’s base rate, which has risen to 5.25% this year, has made mortgages more expensive, deterring potential buyers. “Higher interest rates are squeezing household budgets, and buyers are increasingly cautious,” said Martin Ellis, chief executive of the Property Alliance Group. “This is particularly affecting first-time buyers who rely on mortgage financing.”
The ONS data shows the average flat price in London fell to £450,000 in the third quarter of 2023, down from £512,000 in January 2023. This follows a 5% decline in the first half of the year, according to the same source. The slowdown has been most pronounced in central London, where property prices have dropped 15% compared to the same period in 2022.
How Does This Compare to Previous Trends?
The current decline contrasts with the rapid price growth seen during the post-pandemic boom. From 2020 to 2022, London flat prices rose by 22%, fueled by low interest rates and a surge in remote work that expanded buyer demand. However, the market has since reversed course, with the ONS reporting a 3.4% annual decline in September 2023—the first annual drop since 2018.
Comparative data from Rightmove, a major property platform, highlights regional disparities. While London’s flat prices have fallen, the southeast of England saw a 1.2% increase in the same period. “London’s market is uniquely sensitive to interest rate changes due to its reliance on high-debt buyers,” said Rightmove’s head of property insight, John Phipps.
What Are the Implications for Buyers and Sellers?
The price drop has created a buyers’ market, with fewer transactions reported in recent months. The average time properties spend on the market has increased to 12 weeks, up from 8 weeks in 2022, according to the Royal Institution of Chartered Surveyors (RICS). “Sellers are now facing pressure to reduce prices to attract offers,” said RICS director Matthew Pointon. “This could lead to further declines if demand remains weak.”

For renters, the slowdown has brought some relief. Average rental prices in London rose by 3.1% in the year to September 2023, according to the Department for Levelling Up, Housing and Communities. However, affordability remains a challenge, with 42% of renters spending over 30% of their income on housing costs, per the Joseph Rowntree Foundation.
What’s Next for the Market?
Economists predict the downturn could persist into 2024, depending on interest rate decisions and economic conditions. The Bank of England has signaled a pause in rate hikes, but inflation remains above its 2% target. “If inflation stabilizes, we might see a slight recovery by mid-2024,” said Chris Williamson, chief business economist at IHS Markit. “But the market will remain fragile without stronger wage growth.”
For now, the ONS data underscores the vulnerability of London’s housing market to macroeconomic shifts. As buyers and sellers navigate this uncertain landscape, the pace of recovery will depend on broader economic trends and policy responses.
