William Hill launches pre-configured horse racing Bet Builder
New integration uses racing form and automation to deliver one-click multi-leg bets across UK and Irish racing
William Hill has launched a pre-configured Bet Builder product for UK and Irish horse racing following a multi-year agreement with Checkd Dev.
The deployment integrates Checkd Dev’s Automated Betting System (ABS) into the William Hill sportsbook, enabling the creation and delivery of pre-built, one-click racing Bet Builder selections. The product is designed to give customers faster access to multi-leg racing bets while allowing the operator to scale output consistently across race fixtures.
Under the agreement, William Hill has introduced a range of pre-configured horse racing Bet Builders generated using predefined logic and historical performance data. Powered by racing form, the selections appear directly within the sportsbook’s racing offering, allowing customers to place curated Bet Builder bets without manually constructing each leg.
Pricing and risk management remain within William Hill’s existing trading framework, with the Checkd Dev system designed to complement internal models while automating bet creation and presentation.
From an operational perspective, ABS provides trading teams with backend tools to manage bet generation, updates and settlement in an automated environment. The system is intended to reduce manual workload while supporting consistent Bet Builder products across regulated UK and Irish horse racing markets.
ABS is built on Checkd Dev’s proprietary BRUNO platform and was developed over a two-year period. Initially introduced as a statistics-driven conversion tool, the system has since expanded into a broader automated betting product as operators look to scale pre-configured wagering experiences.
Andrew Grimshaw, Commercial Director at Checkd Dev, said: “Horse racing remains one of the most important categories for UK and Irish operators, and we’re seeing a clear shift toward pre-configured products that help customers engage faster without compromising trading control. William Hill is a standout brand in racing, and we’re excited to see this form-powered bet builder go live and scale across the calendar.”
Owen Duffy, Head of Sport at William Hill added: “Racing remains a core product for William Hill, and we are continually enhancing how customers discover and place bets across racecards. Building on the success of our established Bet Builder tool, this integration introduces a curated, form-led racing bet builder experience that is intuitive to use and consistent across fixtures. Fully aligned with our existing pricing and trading approach, it complements our broader Bet Builder offering while further enhancing the overall customer journey.”
