The UK’s biggest gambling operators have pledged to dramatically boost their funding of responsible gambling programs in an apparent bid to fend off future government crackdowns.

On Wednesday, the BBC reported that gambling operators Bet365, Flutter Entertainment (formerly Paddy Power Betfair), GVC Holdings, Sky Bet and William Hill had agreed to boost their voluntary responsible gambling levy from its current 0.1% of gambling revenue to 1% over the next five years.

The new 1% pledge was made in a letter sent this week to the Department for Digital, Culture, Media and Sport (DCMS), which oversees gambling activities. The Financial Times reported that the letter followed a meeting on Friday between industry reps and the DCMS, at which the government told the industry that its responsible gambling proposals were inadequate to deal with the scope of the problem.

The five companies issued a statement saying they hoped to agree on “a long-term costed plan” for their voluntary contributions by the end of 2019. Expectations are that the pledged amount will eventually return an annual £60m-£100m to responsible gambling programs, including those run by the industry-funded GambleAware.
