This follows reports that the cost of the project has been revised to £270 million (€320 million) after design changes, prompted by the decision not to host Euro 2028 games at the Belfast stadium.

In September, the British government ruled out funding to ensure the stadium would meet the tournament deadline, citing significant risks to public finances. Concerns had also been raised about the project’s projected cost exceeding £400 million.

Casement Park’s redevelopment was first committed to by the Stormont Executive in 2011 as part of a broader strategy to upgrade Belfast’s major sports facilities, including Windsor Park for football and Ravenhill for rugby. While the other projects were completed, Casement Park faced delays due to legal challenges from local residents. Stormont allocated £62.5 million to the project.

The GAA Initially pledged £15 million, while the Irish Government offered approximately £42 million, a contribution that remains available despite the Euro 2028 plans being shelved. However, with the revised costs leaving a shortfall of about £150 million, funding remains uncertain.

Northern Ireland Secretary Hilary Benn told a Westminster committee on Tuesday that he could not confirm whether the UK Government would provide financial support.

Stephen McGeehan, Ulster GAA’s head of operations, told the BBC that “when that conversation happens about additional funding, the GAA will not be found wanting,” but stressed, “We do need to see the colour of the money from the UK Treasury.”

In a statement, Ulster GAA reaffirmed its commitment to delivering the approved 34,500-capacity provincial stadium at Casement Park for Ulster finals and major GAA events.

“The costs of Ulster GAA’s provincial stadium will be significantly lower than the costs required to build a stadium to UEFA specifications,” the statement read. “We recognize the pressures on public finances and will continue to work with the Department for Communities and all partners to ensure the project is delivered efficiently.”

The statement also welcomed the Secretary of State’s recent comments on the importance of building Casement Park and called for an urgent meeting to discuss the project and funding commitments. “We once again call on the British Government, the Minister for Communities, and the NI Executive to deliver on commitments made over 13 years ago to address our strategic stadium needs.”

Ulster GAA highlighted its negotiation of €50 million in partnership funding from the Irish Government, alongside its own commitment of £15 million, and expressed willingness to collaborate with all stakeholders to secure the necessary funds.

Earlier on Wednesday, Stormont Communities Minister Gordon Lyons stated that it was reasonable for the GAA to contribute more than its original pledge. He added that any increase in Stormont’s spending on the project would require approval from the Executive and careful consideration of competing priorities.
