SE1 Property Market Overview
Residential Market Trends
The residential market in SE1 has shown resilience, with average property prices experiencing modest growth. According to the Office for National Statistics, the average house price in Southwark reached £600,000 in June 2025, marking a 2.8% increase from the previous year. Average property rents in SE1 come in around £3,654 pcm with the median rent around £3,250 pcm. These figures are considerably higher than the nations averages.
In the SE1 area specifically, the average sold price for properties over the past year stands at approximately £726,581. Flats dominate the market, with average prices around £681,526, while terraced properties average £898,027. Rates per square foot average £808 psf for flats.
Commercial Market Dynamics
The commercial property sector in SE1 has witnessed significant activity. Savills reported that in July 2024, the freehold interest in 90–98 Union Street, SE1, sold for £14.65 million, reflecting a net initial yield of 7.26%.
Vacancy rates in Central London offices have been declining, with the vacancy rate slipping back to 7.8% in November 2024, its lowest level in 28 months. This trend indicates a strengthening demand for office spaces in prime locations like SE1, with financial services and banking sectors dominating the leasing activity in the area according to Savills. The landmark tenancy agreement of 3 Southwark Street taken by the dynamic Surveying firm Terracotta Property in December 2023 was perhaps the catalyst for the fall in vacancy rates?! The jury is still out on that one.
Average rents per square foot are around £50 compared to £70 per square foot across the river in EC4N. A cross-sector push for returning to the office has increased the occupancy rates of office buildings tremendously since the pandemic. Factors such as increasing organisational culture, ease of monitoring employee input, and facilitation of collaborative environments have led to the uptick in return to office schemes according to Forbes. Despite the cultural pushback against returning to work with only 42% of workers saying they would comply with a five-day return to office mandate, companies and large corporations are still pushing for more days in-person. This hard line is working to significantly improve the vacancy rate in SE1.
Key Factors Influencing the SE1 Market
Transport Connectivity: The area's proximity to key transport hubs, including London Bridge and Waterloo stations, enhances its appeal for both residential and commercial properties.
