New figures from the Office for National Statistics (ONS) reveal how median house prices have changed across south east London boroughs between 2015 and 2025.
The data shows that house prices have risen sharply across all five boroughs, with particularly steep increases recorded since 2023.
We have created a graph which shows how prices in Bexley, Bromley, Greenwich, Lewisham, and Southwark have changed since 2015.
In 2015, Bromley had the highest average house price in south east London, at £365,000.
Bexley had the lowest average price, with homes costing £219,995, while average prices in Lewisham and Greenwich stood at £260,000 and £248,996 respectively.
House prices rose steadily in the years that followed.
By 2017, average prices had increased to £405,000 in Bromley and £331,525 in Southwark, while Lewisham reached £325,000.
Between 2018 and 2020, growth slowed across several boroughs, with prices levelling off or rising only marginally.
In 2019, Lewisham’s average house price dipped slightly to £320,000, while Bexley remained unchanged at £285,000.
By 2020, average prices stood at £295,000 in Bexley, £327,000 in Lewisham and just under £390,000 in Southwark.
Prices began rising more sharply again from 2021 onwards.
That year, average house prices reached £470,000 in Bromley and £400,000 in Southwark, while Lewisham rose to £355,000.
By 2023, further increases were recorded across all boroughs, with Bexley reaching £330,000 and Greenwich £357,000.
The most significant rise occurred between 2023 and 2024.
During that period, Lewisham’s average house price jumped from £350,000 to £483,000, while Southwark saw an increase from £405,000 to £584,000.
In 2024, Southwark became the most expensive borough in south east London within the dataset, overtaking Bromley.
By 2025, average house prices stood at £597,000 in Southwark, £534,000 in Bromley and £495,000 in Lewisham.
Although Bexley remained the most affordable of the five boroughs, prices still rose to £411,000 in 2025.
Overall, the data shows that average house prices across south east London increased by between £190,000 and £265,000 over the ten-year period, depending on the borough.
