The Hidden Contribution in Every Bet You Place
Every time you place a bet on a horse race in Britain, a portion of the bookmaker’s revenue flows back into the sport. Not voluntarily, not as a marketing gesture, but through a statutory mechanism called the Horserace Betting Levy. The Levy is the financial pipeline that connects your betting slip to prize money, racecourse maintenance, horse welfare, and the integrity services that keep the sport honest.
In the 2024/25 financial year, the Levy yield reached approximately £109 million — the fourth consecutive year of growth and the highest figure since the Levy was reformed in 2017. That record is worth celebrating, but it sits inside a paradox that defines the current state of British racing: the Levy is at a high while the betting turnover that feeds it is in sustained decline. Every SP bet feeds back into racing — but the question of how long record contributions can coexist with falling volumes is one the industry cannot avoid.
How the Levy Works: From Bet to Racecourse
The Levy is calculated as a percentage of licensed bookmakers’ gross gambling yield on British horse racing. Since the 2017 reform, all operators — including offshore-based firms serving UK customers — are required to contribute. The rate is set at 10% of GGY, which means that for every pound of profit a bookmaker makes on racing after paying out winners, ten pence goes to the Levy.
The mechanism is administered by the Horserace Betting Levy Board, a statutory body established in 1961. The HBLB collects the contributions, manages the fund, and distributes it according to priorities agreed with the racing industry. The Board operates independently of both government and the betting industry, though its membership includes representatives from both.
The Levy sits within a broader fiscal framework. The UK government also collects Remote Gaming Duty on all online gambling — a tax that generated £1,163 million in 2024/25, up 13% year on year. The Levy and the tax are separate instruments: the tax goes to the Treasury, while the Levy goes directly to racing. But they draw from the same pool of bookmaker revenue, which means that when turnover falls, both the Treasury’s tax receipts and racing’s Levy income are under pressure — though not always at the same rate.
The 2017 reform was a watershed moment. Before it, only bookmakers with a physical presence in the UK were required to pay the Levy, which meant that operators licensed in Gibraltar, Malta, or the Isle of Man could take bets from British customers on British racing without contributing. The reform closed that loophole and immediately increased the Levy base, which is why yields have risen even as the underlying market has contracted. The reform captured revenue that was previously escaping; it did not create new revenue.
The Paradox: Record Levy, Falling Turnover
The headline numbers tell a contradictory story. Levy yield at £109 million is a record since the reform. But average turnover per race has fallen approximately 8% in the latest year, 15% over two years, and 19% over three years, according to the HBLB’s own annual report.
How can the Levy grow while the market shrinks? Two factors explain the divergence. First, the 2017 reform brought offshore operators into the Levy net, expanding the contributor base even as individual bookmakers’ racing turnover declined. Second, bookmaker margins have widened — higher overrounds per horse mean that each pound wagered generates more GGY, and since the Levy is calculated on GGY rather than turnover, fatter margins translate into higher Levy contributions even on lower volume.
Grainne Hurst, CEO of the Betting and Gaming Council, acknowledged this tension. Responding to the 2024/25 figures in iGamingBusiness, Hurst noted that for the fourth year running, contributions had increased to record levels, demonstrating the growing long-term investment that regulated betting provides to British racing — while also expressing concern that racing continues to struggle despite those record contributions.
The paradox is not sustainable indefinitely. If turnover continues to fall, there will come a point where even wider margins cannot compensate, and the Levy yield will decline. The industry is, in effect, running on a combination of structural tailwinds (the reform) and margin expansion (higher overrounds) — neither of which can persist without limit.
Where the Money Goes: Prize Funds, Welfare and Integrity
The HBLB distributes Levy income across three broad categories: prize money improvement, horse welfare and veterinary science, and integrity services including anti-doping and race-day regulation.
Prize money is the largest allocation. The Levy supplements the prize funds put up by racecourses and owners, with a particular focus on supporting the lower tiers of the programme where commercial revenues are thinnest. Without Levy support, many Core-tier fixtures would struggle to offer prize money that justifies the cost of training and transporting horses, which would in turn reduce field sizes, diminish the betting product, and create a negative feedback loop.
Horse welfare receives a significant share, funding veterinary research, racecourse medical facilities, and aftercare programmes for retired racehorses. Integrity services — the work of the BHA’s anti-corruption team, drug testing, and race-day stewarding — are also partly Levy-funded. These functions are invisible to most punters but essential to the credibility of the sport and, by extension, to the trustworthiness of the SP.
The HBLB held reserves of £58.7 million at the end of 2024/25 — well above its target range of £25–35 million. The surplus reflects a deliberate strategy of building reserves during the years of record yield, anticipating that future yields may decline as turnover erosion eventually overwhelms the reform’s structural benefits. It is a prudent cushion, but it also underlines the Board’s own expectation that the current trajectory is not permanent.
Why the Levy Matters to SP Bettors
The Levy matters to SP bettors for a reason that goes beyond civic interest. The quality of the SP depends on the quality of the market, and the quality of the market depends on the health of the sport. Prize money attracts runners. Runners create competitive fields. Competitive fields attract betting volume. Betting volume produces deep, liquid markets from which a robust SP can be calculated. The Levy is a critical link in that chain.
When the Levy funds adequate prize money at Core fixtures, those fixtures attract enough runners to form meaningful races with genuine betting interest. When Levy funding falls or is redirected, the lower tiers of the programme thin out — fewer runners, less competitive races, lower turnover, and an SP drawn from a shallower pool. The connection between your SP bet and the Levy is not abstract; it is structural.
There is also a self-interest argument. Every SP bettor benefits from a sport that invests in integrity. Drug-tested horses, properly stewarded races, and enforced anti-corruption rules mean that the SP you receive is more likely to reflect genuine market conditions rather than manipulation. The Levy pays for that assurance, and that assurance underpins the value of every bet you place.
The Levy’s future is not guaranteed at its current level. If turnover continues to erode and the structural benefits of the 2017 reform are exhausted, the Levy yield will fall — and the first casualties will be prize money at the lower tiers, field sizes at everyday fixtures, and ultimately the depth of the market from which the SP is drawn. Every SP bet feeds back into racing — and racing, in turn, feeds back into the SP. That loop works only as long as the money keeps flowing.
