Estimated, not guaranteed — a free bet pays your winnings and keeps the stake, so it's worth less than the headline figure.
What it's really worth
The headline is £50.00. Allowing for the way the reward actually pays out, a realistic range is £35.00–£40.00. An estimate, not a promise — and it's lower than the headline because a free bet returns your winnings and keeps the stake.
Is it worth it?
SBK's Bet £20 Get £50 is a new-customer offer, so it's a one-off: worth judging on what you get back for the money you have to put through, not on the headline.
Realistically it returns about 1.9× your £20 qualifying stake — roughly £35 to £40 of usable value against a £50 headline.
That's middling against the welcome offers we currently track — it beats 53% of them on our score.
The part worth knowing before you start: the qualifying bet has to be at 3.00 or bigger.
