About the Independent Betting Adjudication Service
IBAS adjudicates transactional disputes across all sectors of licensed gambling in the UK. It handles disputes that cannot be resolved through an operator’s internal complaints process. Since 2015, licensed gambling operators in Great Britain have been required by the Gambling Commission to offer ADR to their customers, and IBAS is one of eight UKGC-approved ADR providers. IBAS receives and processes approximately 90% of complaints from gamblers across all sectors of gambling in Great Britain. Its adjudication panel — comprising 15 members with gambling, consumer redress, and complaint-handling expertise — reviews disputes on the basis of submitted written evidence, applicable operator terms and conditions, and UKGC regulatory requirements. Decisions are binding on registered operators up to a value of £10,000. The service is free to consumers and funded by annual operator registration fees.
For operators, registration with IBAS requires agreeing to be bound by its adjudication decisions. Consumers must first exhaust the operator’s internal complaints procedure — or wait up to eight weeks without resolution — before submitting a dispute to IBAS. Complaints are submitted in writing via the IBAS website. Most cases resolve within 8 to 12 weeks of submission, though complex disputes may take longer. IBAS will decline to adjudicate if the consumer has not first engaged the operator, if the complaint falls outside the 12-month submission window, or if the dispute relates to responsible gambling or social harm rather than a transactional matter — the latter category remaining outside ADR scope under current UKGC rules. IBAS recorded its 100,000th adjudication case in 2025.

Industry Impact & Relevance
IBAS is the dominant ADR provider in the British gambling market by volume, handling approximately 90% of all gambling disputes referred to ADR across all licensed sectors. For operators registered with IBAS, adjudication decisions are binding up to £10,000 — a practical compliance requirement rather than a reputational choice, given that the UKGC mandates ADR availability as a condition of holding a UK operating licence. Association with IBAS signals to players that a formal, independent escalation route exists for unresolved disputes, which carries direct bearing on player trust. Since its founding, IBAS has resolved over 90,000 disputes and returned over £7.5 million to customers.
The most significant structural question facing IBAS is whether it will assume the role of the proposed Gambling Ombudsman recommended by the 2023 Gambling White Paper. The White Paper called for the creation of a single ombudsman body to handle social responsibility and gambling harm complaints — a category currently outside IBAS’s ADR scope. IBAS has stated it is ready to step into the ombudsman role with a consumer-focused plan pending stakeholder support and an appropriate funding model. Its Ombudsman Association membership and market dominance position it as a strong candidate. If appointed, IBAS would gain significantly expanded remit and mandatory operator registration — substantially increasing its commercial and regulatory importance. Until that appointment is confirmed, IBAS remains an essential but structurally constrained service, unable to adjudicate the growing category of responsible gambling complaints that represent the most contested area of UK consumer redress.
