Local London businesses are set to gain further access to advertising opportunities across London’s Underground network, after Outdo secured a new contract to operate poster advertising outside of Transport for London Underground station sites.
The new agreement expands Outdo’s London portfolio and will give local businesses at 30 locations in zones 3 to 9, access to high-footfall locations on the transport network. Outdo is aiming to make these sites more accessible to SMEs, local businesses and regional advertisers looking to reach audiences in the communities they serve.
These sites will enable businesses to target customers close to where they operate, helping them build awareness, drive footfall and connect with local communities through high-impact out-of-home advertising.
The contract follows a series of recent local authority wins for Outdo across the UK, including lamppost banner, boundary sign and roundabout advertising networks. It marks a further step in the company’s growth and its ambition to broaden access to outdoor advertising for businesses of all sizes.
Mike Brennan, CEO of Outdo, says: “Securing this partnership with Transport for London is a significant milestone for Outdo and reflects the progress we have made in building the UK’s fastest-growing independent outdoor media business.
“The London Underground is one of the world’s most recognised transport networks, and we’re proud that TfL has entrusted us to help maximise the value of this portfolio. Together, we have an opportunity to broaden access to one of the UK’s most iconic advertising estates, supporting businesses of all sizes while continuing to grow the commercial potential of the network.”
From outdoor advertising to a city-wide media network
The Outdo agreement fills an important gap in Transport for London’s broader advertising proposition. While much of TfL’s estate has traditionally been geared towards national brands and large campaigns, these smaller sites outside stations offer a more affordable and geographically precise way for independent retailers, hospitality operators and service businesses to reach people close to the point of purchase.
TfL already operates one of the world’s most valuable out-of-home advertising estates. Global manages advertising across the Tube, London Overground, DLR, London Trams and Elizabeth line, while JCDecaux manages more than 4,700 London bus shelters. Advertising is also available on TfL’s website and TfL Go app through CAN Digital Solutions. TfL reported that its commercial media activities generated approximately £150m in 2023/24, which was reinvested in the transport network. TfL says its estate reaches millions of passengers each day.
That proposition is becoming increasingly digital and data-led. Under an eight-year contract that began in 2025, Global plans to install more than 1,000 small-format digital screens across all nine fare zones, alongside 150 full-motion, 3D-enabled large screens and new immersive formats. Its Access All Audiences planning tool combines depersonalised TfL data with information from TGI, IPA TouchPoints and YouGov, shifting the offer from buying particular panels towards planning campaigns around the audiences moving through the network. Global describes this as the biggest transformation of the Underground advertising estate in its history.
This does not make TfL a retail media network in the strictest sense. It does not generally possess the individual shopping histories, product-level sales data or closed-loop attribution offered by a supermarket or ecommerce marketplace. However, its combination of audience scale, movement data, location, time of day and proximity to shops makes it an increasingly important part of the wider commerce-media market.
The stations themselves also sit within a substantial commercial ecosystem. Places for London, TfL’s property company, manages more than 1,500 businesses across its estate, 95% of which are SMEs. That creates the potential for advertising to connect journeys with the businesses and services situated in and around transport hubs – although turning that potential into genuine retail media would require closer integration between advertising exposure, merchant offers and measurable store visits or sales.
The Outdo contract therefore adds a useful “local layer” to TfL’s proposition. A large advertiser can use digital screens and network-wide audience planning to reach London at scale; a neighbourhood restaurant, gym, retailer or professional service can now target passengers leaving a particular outer-London station. For TfL, it opens previously underused inventory to the long tail of advertisers. For local businesses, it offers something increasingly valuable in retail media: the ability to address customers in a particular place, at a particular moment and within walking distance of a transaction.
