Betfair vs William Hill

Quick verdict: who should pick which

Choose Betfair if price is your priority. On our sample of 213 markets it returned the best available price 53% of the time and ran a noticeably lower margin, so over a season of Premier League and horse racing bets the value adds up. Its withdrawals score (8.5) also nudges ahead, and Fast Payout is listed among its features.

Choose William Hill if you want Bet Builder and a marginally higher-rated app. William Hill lists Bet Builder in its feature set and Betfair does not, so if you like stacking same-game selections on a football or GAA match, that's a real dividing line. Its licence and safety rating (9.3) is the highest of the two.

Avoid drawing a line on live streaming or cash out — both offer them. The genuine trade-off is value (Betfair) versus Bet Builder plus a slightly stronger app (William Hill).

Odds and value compared

This is where the two separate most. Betfair rates 8.9 for odds against William Hill's 7.7.

• Best price share: Betfair 53% vs William Hill 17% (across 213 and 219 sampled markets respectively)
• Average margin: Betfair 4.29% vs William Hill 6.96%

A lower margin means the bookmaker builds in less of an edge, so prices are closer to true. On popular markets like Premier League match odds or ATP Tour tennis, that gap in best-price share is the difference between routinely getting the top number and settling for a shorter one. If you line-shop or bet in any volume, Betfair's pricing is the standout factor here.

William Hill still holds solid market coverage (8.5) and sports depth (8.6), matching Betfair on depth, so the shortfall is about price rather than what's available to bet on. You can compare live numbers on our betting odds Ireland pages before you commit.

Sports and competitions

Both cover the core Irish card the same way on our ratings — sports depth is 8.6 for each. That means Football, Horse Racing, GAA, Rugby, Tennis and Golf are all served.

For football, expect the Premier League, Serie A, Ligue 1, Champions League, Europa League, Copa Libertadores and the World Cup. Tennis runs across ATP Tour and WTA Tour. Betfair's higher market coverage rating (8.8 vs 8.5) suggests slightly broader market menus within events, which pairs with its better pricing for punters who dig into side markets.

For Irish racing and GAA weekends, the practical takeaway is that both hold the fixtures — the decider is again price (Betfair) versus Bet Builder for same-game football and GAA bets (William Hill).

Live betting, streaming and Bet Builder

Both bookmakers list Live Betting, Cash Out and Live Streaming, so in-play punting and streaming eligible events are covered either way. Betfair rates higher for live capability (8.7 vs 8.2), which points to a smoother in-play experience and quicker market turnover during matches.

The clear feature split is Bet Builder. William Hill lists it; Betfair's features do not. If combining, say, over 2.5 goals, both teams to score and a named player to be carded on the one Premier League slip matters to you, William Hill is the pick. Betfair counters with Fast Payout in its feature list.

For cash out on live GAA or rugby, either works. See our Cash Out and Bet Builder pages for which other Irish bookmakers offer these.

Payments, deposits and withdrawals

The banking setup is near-identical on paper.

• Deposit methods: both accept Debit Card and PayPal
• Minimum deposit: €10 at both
• Withdrawal time: 0–24h at both

Withdrawal ratings differ slightly — Betfair 8.5 vs William Hill 8.2 — and Betfair lists Fast Payout as a feature, so on the balance of the data it has the edge for getting winnings back quickly. Payments scores are level at 8.4.

If you specifically want PayPal, both qualify. Irish bettors who prefer other rails should note that only Debit Card and PayPal are confirmed for these two here; for Apple Pay, Revolut Pay, Visa, Mastercard or Bank Transfer options, check our PayPal betting sites and Apple Pay betting sites lists to see who supports what.

Apps and support

Both run iOS and Android apps. William Hill rates marginally higher for its app (8.5 vs 8.4), so if the mobile experience is your main criterion it has a slim advantage. Both apps carry live betting, cash out and streaming.

Customer support is where William Hill pulls clear: 8.2 against Betfair's 7.9. If you value being able to sort account or payment queries quickly, that gap is worth weighing — particularly during busy racing festivals or big match weekends when contact volumes spike.

Safety and licensing

Both operators are licensed and both score at the top of our table for safety — William Hill 9.3, Betfair 9.2. Gambling in Ireland is regulated by the Gambling Regulatory Authority of Ireland (GRAI), and the minimum age to bet is 18.

We verify safety on the basis of licence and register checks in our data rather than any first-hand account use. On that measure there's little between them: both are established brands (William Hill founded 1934, Betfair 2000) sitting at the top end of our safety scoring. Neither should give a cautious Irish punter pause on trust grounds.
