London Building Construction Age
2025-02-12
As of the end of 2024, England and Wales had approximately 21.2 million residential housing units with Energy Performance Certificates (EPCs), which represents a significant portion of the 24.8 million households recorded in the Census 2021. Among these properties, 85% fall within an estimated construction age band. Let’s explore the details of London buildings.
Housing Age Distribution in London
London contains 2.92 million housing units with an estimated construction age band. While we cannot determine the exact average age of the units due to the presence of only age bands and the absence of precise ages for some properties, the high proportion of housing units with known age bands allows us to create a home age index map. This map visualizes where older and newer buildings are located.
Most houses built before 1900 are found in Kensington and Westminster, which account for nearly one-fourth of all housing units in London from that period. 47.3% (46.7k) of homes in Kensington and Chelsea were built before 1900, 23.2% (23k) between 1900-1929, while the remaining 29.5% were built after 1930.
In contrast, most developments since 1996 have taken place along the banks of the Thames River, particularly in the E and SE postcode areas, such as E14, E16, SE16 and SE28. Nearly 21000 units (53.1%) units in E14 were built after 1996, along with 7000 (40.5%) in E16.
