The UK gambling market’s participation rate continues to decline despite the resumption of some major football betting markets.

Figures released Monday by the UK Gambling Commission (UKGC) show there were 14.66m active gambling customers in the month of May, down from 14.83m in April and from 15.62m in March. The UKGC compiled its stats from data supplied by the market’s biggest online operators, covering around 80% of the UK’s online market.

The return of Germany’s Bundesliga football boosted betting revenue to £101.3m in May, up 63.6% from April but still well back of the nearly £161m in March (which included the Cheltenham Festival). Virtual betting suffered as a result of the live game’s return, falling 12% month-on-month to £11.3m, while eSports betting rose 36% to £4.6m (which was triple the March eSports tally).

Online slots revenue jumped 29.4% to just under £184.3m, while other casino games rose a mere 1.2% to £77.9m. Hopes of another online poker boom turned to bust in May, as revenue slipped to £18.3m, down 8.7% from April although that was still 50% higher than March. The poker bust had a negative effect on average gambling session length, which fell 8.3% from April to May.
