Who Owns Railway Arches? The Complete Guide

Three organisations control the vast majority of railway arches in the UK: The Arch Company (Blackstone), Places for London (TfL), and Network Rail. Each has different lease terms, letting processes, maintenance standards, and tenant relationships.

Understanding your landlord is critical because it shapes everything from your rent review cycle to your termination risk. This guide maps the ownership landscape, compares how each landlord operates, and tracks active regeneration projects opening up new supply.

The Arch Company is the dominant force in UK railway arches, managing approximately 5,200 properties across 24.8 million sqft. The portfolio was acquired from Network Rail in 2019 for £1.46 billion as a 150-year leasehold (not freehold), ensuring Network Rail retains structural control.

In late 2025, Blackstone bought out Telereal Trillium's 50% stake, making it the sole owner. The portfolio is now valued at approximately £2 billion.

The Arch Company publishes a non-legally-binding Tenants' Charter committing to preserving a diverse business mix and providing a 24/7 contact centre. Void rates remain elevated at approximately 1,300 empty arches across London.

Places for London is TfL's property arm, managing approximately 800–900 arches across the Underground and Overground network. Over 90% of tenants are SMEs.

Their “Our Arches Plan” (published October 2025) sets out a strategy through 2030, with a focus on decarbonisation (air-source heat pumps, LED lighting), SME clusters, and “human-centric design.”

Key Features

• 5-year Growth Leases — discounted rent that steps up to market rate over the term
• “London Lease” — requires tenants to pay the London Living Wage and share environmental impact data
• Social Value Leases — prioritise community benefit alongside commercial return
• Revenue target — aiming to double gross rental income from £12M (2025) to £28M by 2032

Key development areas include Kilburn, Kingsland, Lockton Street, and the flagship Wood Lane Arches at White City (31 newly regenerated double-frontage arches).

Network Rail retained approximately 2,500 arches deemed essential for railway operations after the 2019 sale. These are concentrated around major termini: London Bridge, Waterloo, and Victoria.

Key Differences

• Break and entry rights — sometimes with as little as 7 days' notice for operational needs
• Flexible rental packages for SMEs with RPI-linked rents and 3-month notice periods
• Pop-up retail — 13 pop-up locations across 19 stations offered in 2025

Great British Railways Transition

Network Rail will transition to Great British Railways (GBR) under the Railways Bill introduced in November 2025. GBR is expected to be operational by early 2027 with a 30-year Long-Term Rail Strategy including “unlocking new house-building and economic growth.”

The current Bill is silent on commercial tenant protections. How the transition affects existing arch tenancies remains unclear.

New supply is coming online across London and the UK. These projects are creating opportunities for businesses looking for newly refurbished arches.

Secondary owners include local councils (Southwark, Hackney, Waltham Forest), housing associations (Notting Hill Genesis at Kidbrooke), and private developers (“The Stage” Shoreditch, “The Goodsyard”).
