The UK's dominant betting exchange up against the UK's biggest global sportsbook. We compare welcome offers, odds, markets, app quality and racing coverage.
Betfair and Bet365 are two of the biggest names in UK betting, each licensed by the UK Gambling Commission and each with a global footprint. They approach the market from different angles.
Betfair pairs a standard sportsbook with the UK's leading peer-to-peer betting exchange, letting you back or lay any selection and trade positions in-play. Bet365 is the benchmark traditional sportsbook — unmatched market depth, free live streaming and a top-rated mobile app, but no exchange functionality.

Bet £10, Get up to £50 in Free Bets
The only major UK book with a full betting exchange. The £30–£50 welcome tops the table on headline value, though the tokens are earmarked for Bet Builders and accas.
Bet £10, Get £30 in Free Bets
Bet365 remains the benchmark UK bookmaker — unmatched market depth, the most stable mobile app on the market, and free in-play streaming across thousands of events every month.
Betfair: Bet £10, Get up to £50 in Free Bets. Betfair's welcome applies to the sportsbook — the exchange runs separate promotions.
Bet365: Bet £10, Get £30 in Free Bets. Qualifying deposit and wagering conditions apply — always check the operator's current T&Cs before opting in.

On liquid football and tennis markets, Betfair Exchange prices (after commission) often beat Bet365's fixed odds. Bet365 counters with far greater breadth — more leagues, more markets per fixture, and Bet Builder on a huge range of events.
Bet365 offers Best Odds Guaranteed plus free live streaming of UK racing. Betfair's edge is the exchange — lay horses, trade a position in-play, and sometimes find bigger prices on outsiders than any fixed-odds book will post.
Bet365's app is consistently rated among the best in UK betting for stability and streaming. Betfair's app carries more functionality because it houses both sportsbook and exchange in one place — great for power users, more of a learning curve for casual bettors.
Pick Betfair if you want exchange access, plan to lay bets, or want to trade in-play. Pick Bet365 if you want the deepest market coverage, live streaming and a straightforward fixed-odds sportsbook.
Both are among the most trusted UKGC-licensed operators in the UK market. Serious punters often hold both — Bet365 for depth, streaming and accas, Betfair for exchange-driven value and in-play trading. See our free bets hub and best betting sites guide for more comparisons.
