The Senet Group was set up last year by Paddy Power, Ladbrokes, William Hill and Coral to promote responsible gambling in the UK.
Scotbet now joins the four founder members in committing to abide by a code of conduct designed to meet certain standards of social responsibility in gambling.
The bookmaker will be given a three-month ‘grace period’ to fully comply with Senet Group commitments.
Membership for the Senet Group remains open to all gambling operators.
“We’ve always placed a high priority on promoting responsible gambling, so it seemed natural to join Senet as a mark of our commitment to that principle,” Scotbet chairman John Heaton said.
“In keeping with Senet’s rules, we have withdrawn all advertising of gaming machines from shop windows and will be devoting 20% of window advertising to responsible gambling messages.
“While most customers enjoy betting safely, it’s important that the industry plays its part in protecting vulnerable people. We look forward to working with Senet to achieve that goal.”
Senet Group chair Wanda Goldwag added: “We now have about 90% of betting shops in Scotland signed up, which is good news for their customers and all those who want to see higher standards of responsible gambling.”
