This data, sourced from operators, reflects the period between March 2020 and March 2025, inclusive, and covers online and in-person gambling covering Licensed Betting Operators (LBOs) found on Britain’s high streets.

This release compares Quarter 4 (Q4) of financial year 2024 to 2025, with Q4 of 2023 to 2024, looking at how the market has changed in comparative periods over a year.
