London is seeing the highest rates of gambling in the country, and experts gathered in City Hall to address the issue.

With half of London residents estimated to engage in various forms of gambling, a panel of experts in gambling treatment met at the London Assembly on Wednesday.

Marguerite Regan, Head of Gambling at the Office for Health Improvement and Disparities, told the Assembly:

“Not all gambling is necessarily problematic, although when it comes to an addiction, it can often lead to other addictions such as drug and alcohol abuse.”

Harmful gambling’

The challenges go beyond identifying the health concerns attributed to gambling addiction.

Defining “harmful gambling” remains difficult, according to Dr. Tom Coffery OBE, the health advisor to London Mayor Sadiq Khan.

He said the lack of a clear definition blocks addressing the root of the issue.

Dr. Tom Coffery said the lack of consensus on what constitutes “harmful gambling” has meant the Mayor’s ability to decide which gambling companies to restrict in advertising, has been stalled.

Despite the Mayor’s 2021 manifesto commitment to prohibit gambling advertisements on the Underground, no such ban has happened, two years later.

In June 2022, a year after the Mayor’s pledge, The Guardian found through an FOI request that during the first quarter of 2022, gambling outlets paid Transport for London (TFL) £1.17m for advertising rights.

‘You don’t get ads for heroin – why for gambling?’

Dame Clare Gerada, founder of Primary Care Gambling Service, expressed her concern about the scale of gambling advertisements on London Underground:

“On my way down today, I took the Tube and saw over 13 adverts promoting gambling. You don’t get ads on the tube to encourage heroin use; why are we doing it with gambling?”

Former gambling addict Harj Gahley, agreed and believes a wider ban on gambling ads needs to be set up.

Mr Gahley’s problems with gambling began in 2009 when he placed his first bet at a bookmakers.

He hid his addiction from everyone close to him, and by 2020 he had lost over £250,000.

He was dealing with severe mental health problems relating to his addiction which led to him attempting to take his own life.

Mr Gahley views this incident as a turning point which led him to seek professional help.

He now works for Red Card, a charity aiding those facing similar challenges, and advocates for a complete ban on gambling ads on London’s transport network, drawing parallels with Bristol’s successful move in 2021.

Dr. Tom Coffery said efforts to stop gambling at the earliest stage are ongoing through the A New Deal for Young People initiative.

The programme aims to identify characteristics in young people that may lead to problematic gambling and aims to provide mentorship to 100,000 young people in London by early next year.
