Gambling companies splurge on public transport advertisements in the UK

Gambling advertising spreads across London transport

Gambling adverts have become common across London’s transport network. Posters appear on trains, station walls, platforms, and long corridors used by millions daily. Records show companies spent about £7.5m advertising on Transport for London services during Sadiq Khan’s three terms as mayor.

The spending covers many parts of the network that commuters use every day:

• London Underground and Overground trains

• Trams and the Docklands Light Railway

• Victoria coach station and the Elizabeth line

The rise suggests a clear business push — steady, planned, and highly visible. For many passengers, the ads now feel routine. They appear often, repeat messages, and stay in sight during long journeys. Public transport offers attention that few other spaces can match.

A promise made in 2021 still waits

In 2021, Mayor Khan said he would ban gambling adverts on TfL services. The promise followed concerns about harm and public exposure. Many expected a quick change. Instead, advertising continued and later increased.

Since that pledge, gambling companies have spent around £4.6m on transport ads. The number of campaigns also grew. In 2025, TfL approved 223 gambling advertising campaigns. That total was roughly double the number approved in 2024.

The figures create tension — between political promises and daily reality. Critics say the delay weakens trust. City Hall responds that the issue remains active and under review.

Legal concerns slow firm action

City officials say the pause reflects legal caution. A ban without strong proof of harm could face court challenges. That risk shapes the mayor’s approach — careful, slow, and focused on protection.

Officials compare the situation with a past junk food advertising ban. That policy relied on clear government-backed health evidence. Gambling advertising lacks similar national support at present. Without it, TfL could face costly legal claims.

The mayor’s office said the government is reviewing gambling harms and advertising impact. Action may follow once that work ends. Until then, existing rules remain in place.

National inaction limits local choices

Gambling policy often depends on national departments. The Department for Digital, Culture, Media and Sport usually provides evidence for change. In this case, it has not shared plans or findings.

That silence leaves London with few safe options. Hence, the promise made in 2021 remains unresolved — almost five years later. For now, gambling ads stay visible, and companies keep buying space along the city’s busiest routes.
