Every Bet on a British Race Funds the Sport — Here Is How
Most punters have no idea that a slice of every bet they place on British horse racing goes back into the sport. I certainly did not when I started. The mechanism that makes this happen is the Horserace Betting Levy — a mandatory payment from licensed bookmakers to the Horserace Betting Levy Board, which then distributes the money to prize funds, integrity services and equine welfare. The levy is one of the most unusual financial structures in any sport, and in FY2024-25 it reached a record 108.9 million pounds — the highest since the current system was overhauled in 2017.
Understanding the levy matters for bettors because it shapes the sport you are betting on. Prize money levels, the quality of veterinary services at racecourses, the funding of anti-doping and integrity operations — all of these flow from the levy. When the levy rises, racing gets better resourced. When it falls, the sport contracts. The tension between betting revenue and sporting investment is at the heart of every major debate in British racing right now.
How the Levy Is Calculated: 10% of GGY on British Racing
The current levy structure is deceptively simple on paper. Every licensed bookmaker that accepts bets on British horse racing pays 10% of its gross gaming yield (GGY) from those bets to the Horserace Betting Levy Board. GGY is the difference between the total amount staked by customers and the total amount paid out in winnings — essentially the bookmaker’s gross profit on British racing.
Grainne Hurst, CEO of the Betting and Gaming Council, has highlighted an important paradox: levy contributions have risen to record levels for four consecutive years, demonstrating what she describes as the growing long-term investment that regulated betting provides to British horse racing. Yet she has also noted that racing continues to struggle both as a sport and as a betting product, with turnover falling year-on-year despite those record contributions.
The paradox exists because the levy is calculated on profit, not on turnover. A bookmaker can have a declining volume of bets but a higher profit margin — meaning fewer punters are betting, but the bookmaker is retaining more of each pound staked. A festival like Cheltenham where punters have a bad week (backing losers) inflates the bookmakers’ GGY and pushes the levy up, even if the total amount bet was lower than the previous year. Conversely, a year where punters back multiple big-priced winners can suppress the levy despite high turnover.
The HBLB distributed 66.9 million pounds to prize money alone in FY2024-25, alongside 19.4 million for regulatory and integrity services and 7.9 million for recruitment, training, horse welfare and promotion. Those numbers represent the single largest external funding source for British racing.
Prize Money, Integrity and Welfare: The Levy Allocation Breakdown
I attended a mid-tier National Hunt meeting last winter where the prize money for a Class 4 novice hurdle was around 5,000 pounds to the winner. That money did not appear from nowhere. A portion came from entry fees paid by owners, another from racecourse contributions and a significant share from levy funding. Without the levy, many of these smaller races — the bread and butter of the British racing calendar — would either carry prize money too low to attract runners or would not be staged at all.
For 2026, the HBLB increased its funding commitment: an additional 4.4 million pounds for prize money, bringing the total package to 77.1 million, and an extra 1.2 million for regulatory initiatives. That increase matters because prize money is the primary incentive for owners to keep horses in training and for trainers to enter them in races. Higher prize money means more runners, more competitive fields and, ultimately, better betting markets.
The integrity budget covers the work of the BHA’s integrity department, which investigates suspicious betting patterns, enforces the rules of racing and manages anti-doping testing. This is funded by the levy because betting and integrity are inseparable — the betting public needs confidence that races are run fairly, and operators need assurance that the product they are pricing is honest. Without integrity funding, the credibility of the betting market collapses.
Equine welfare receives a smaller but vital allocation. Levy funds support the retraining of racehorses after their careers, veterinary research and racecourse safety improvements. The welfare component is often overlooked in discussions about levy economics, but it underpins the sport’s social licence — the public acceptance that racing can be conducted humanely.
Record Levy, Falling Turnover: The Paradox in 2025 Data
Here is the number that should concern every punter who cares about the long-term health of British racing: total betting turnover on UK horse racing fell 4.3% in 2025 compared to 2024, and a full 10.7% below 2023 levels. Turnover per race dropped 5.6% year-on-year. Those are not marginal declines — they represent a structural contraction in the amount of money flowing through racing’s betting markets.
Yet the levy reached a record. The gap between falling turnover and rising levy tells a story about margins. Bookmakers are making more per pound bet, which keeps the levy high even as the volume of betting decreases. For racing, this is a dangerous equilibrium. A sport that depends on betting revenue cannot sustain indefinitely if the number of bettors and the total amount they stake keeps shrinking.
The causes of the turnover decline are debated, but affordability checks are consistently cited as a primary driver. Since February 2025, the threshold for enhanced affordability checks dropped to 150 pounds in net deposits per month, a level that catches a far larger pool of regular bettors than the previous 500-pound threshold. Whether the checks are necessary for harm prevention or counterproductive by pushing bettors to the black market is a separate debate — the turnover data is clear either way.
For the levy, the immediate future looks secure: record income, increased prize money, growing integrity budgets. But the foundation is eroding. If turnover continues to fall, margins will eventually compress (competition between operators tends to squeeze profits over time), and the levy will follow. Racing’s financial model works when people bet on racing. Every year that turnover declines is a year the model gets more fragile.
