The Most Expensive Boroughs in London

London was recently named the best city in the world by Resonance Consultancy, which analysed factors such as employment opportunities, cultural diversity and high-profile events hosted in the city. Therefore, it is no surprise that house prices in the most sought-after areas of London come with a hefty price tag.

The top 10 most expensive streets to buy property in the UK are all in exclusive areas of London. The ranking of the most expensive addresses may differ from report to report. However, the same areas in London tend to occupy the top slots year upon year.

Why London boroughs are in high demand

Only New York’s financial district is larger than London’s, and the exceptional architecture, nightlife and restaurants add to the pull of living in London.

From the excitement of the West End to the long list of Michelin starred restaurants, residents of London are spoilt for choice when it comes to entertainment and dining out. While other areas of the UK offer picturesque countryside, London offers an abundance of green space and scenic landscapes in top beauty spots such as Richmond Park, Hampstead Heath and Hyde Park.

The nightlife in London and top sporting events draw people to London, with popular celeb haunts dotted around the city, allowing the rich and famous to enjoy the more extravagant VIP treatment in luxury restaurants, hotels and bars.

Naturally, location is key – but the properties themselves hold vast appeal, such as Islington’s stunning Georgian and Victorian homes or the city’s high-end apartments. Adding to London’s list of most expensive streets, is the ever-expanding list of sought-after developments.

Consider the Candy brothers’ One Hyde Park Corner, where prices range from £45,000 to £175,000,000, and John Caudwell’s £2bn 1 Mayfair development, set for completion in 2026. Then there the new developments south of the River Thames at the Foster + Partners and Frank Gehry-designed Battersea Power Station. The average price of a property within Battersea Power Station is around £2m. In rapidly changing Nine Elms, prime and super prime developments include Thames City, where a penthouse was listed for £32m in spring 2025.
