Hi Sir Ivor, Its been a while since restrictions hit me but from memory:
Ave stake per race would have been £10 to £50.
Skybet were first to restrict, removing BOG and then restricting me to 50p max stake per bet (think this was circa 2023)
Then Betfair Sportsbook and Paddy power followed suit- Again limited to £1 per selection maximum
Best 365 restricted after that- 25p per race max stake
The tote then started asking for proof of affordability. As did Betfair exchange.
All these accounts are now closed apart from Betfair which I still use to watch racing for free.
After that I curtailed my betting on horses. I still follow the jumps season and if I fancy a bet I go to the local William hill shop but probably gamble less than 1% of the total stake I used to now. I don’t bet on any other sports.
