Transport for London Awards South Kensington Station Upgrade Contract to Deliver Step-Free Access and New District Line Platform

Major Contract Award Signals Transformation for World-Famous Museum Gateway

LONDON, United Kingdom — Transport for London (TfL) has marked a decisive operational breakthrough in the generational transformation of South Kensington Tube station, officially confirming its intention to award the comprehensive design and build contract to British civil engineering firm Costain. Procured under TfL’s Infrastructure Improvement Framework, the landmark contract unlocks detailed engineering and full-scale construction works to deliver universal step-free access, eliminate chronic passenger bottlenecks, and construct a brand-new eastbound Circle and District line platform.

Serving as the world's primary public transit gateway to London’s celebrated Exhibition Road cultural quarter—home to the Natural History Museum, the Science Museum, the Victoria and Albert Museum (V&A), and Imperial College London—South Kensington accommodates more than 30 million passenger journeys annually, making it one of the most heavily patronized stations across the entire London Underground network.

New Eastbound Platform and High-Capacity Step-Free Elevators

Under the approved multi-million-pound engineering blueprint, construction teams will build a dedicated, high-capacity eastbound platform for the Circle and District lines, reinstating an disused platform footprint to allow trains to board and alight passengers seamlessly without triggering service delays across the inner London subsurface circle. The wider station footprint will undergo substantial platform widening, staircase reconfiguration, and modernized ticket hall gate line installations.

Crucially, the project delivers full step-free accessibility from street level directly to all station platforms. Modern, energy-efficient elevators will link Thurloe Street directly to the subsurface ticket halls, while dedicated deep-level lift shafts will connect down to the Piccadilly line platforms, ensuring that families with strollers, elderly commuters, and passengers with mobility impairments can access the cultural precinct without physical barriers.

Restoring Grade II-Listed Heritage and Delivering Sustainable Housing

The engineering program is being delivered in strategic collaboration with joint-venture development partners Native Land and Places for London, TfL’s commercially driven property company. The project incorporates the meticulous architectural restoration of the station's historic Grade II-listed Victorian shopping arcade, preserving its iconic nineteenth-century ironwork and decorative masonry while modernizing retail shopfronts.

Surrounding the station entrance, a sensitive, low-carbon urban development will deliver 50 new high-quality homes, including on-site affordable housing, alongside contemporary office accommodation and welcoming public realm landscaping, blending historical architectural conservation with forward-looking urban design.

Enabling Works Launching in Autumn 2026 Ahead of 2031 Milestone

Transport officials confirmed that initial enabling activities, utility realignments, and site investigations will get underway in autumn 2026, beginning with specialized preliminary structural preparations within retail properties on Thurloe Street. Heavy civil engineering and underground shaft excavations will ramp up steadily across subsequent phases.

Full station commissioning and public opening are projected for 2031, strategically timed to coincide with the momentous 150th anniversary of the Natural History Museum. The station transformation ensures that London’s premier scientific and educational district will be anchored by a world-class, accessible, and high-capacity transport hub for the next century of visitors.
