The British government will provide 2.8 million pounds ($4 million) to pursue a five-nation bid for a World Cup with Ireland.
The English Football Association disclosed the financial assistance for a potential British Isles bid on Monday as it received fresh backing from British Prime Minister Boris Johnson.
"We are very, very keen to bring football home in 2030. I do think it's the right place," Johnson said in an interview with "The Sun" newspaper.
"It's the home of football, it's the right time. It will be an absolutely wonderful thing for the country."
Johnson calling England the "home" of football is the language the country's bid for the 2018 World Cup sought to avoid so the FA didn't give the impression of seeming entitled to host the FIFA men's showpiece.
The 2018 bid flopped, with only two of 22 FIFA votes received, despite Prince William lobbying executive committee members on the eve of the decision.
England, which hosted and won the 1966 World Cup, is exploring bidding with Scotland, Wales, Northern Ireland and Ireland.
London, Glasgow, and Dublin are being used this year among the 12 cities across the continent staging the 2020 European Championship that was rescheduled due to the coronavirus pandemic.
"We will continue to undertake feasibility work to assess the viability of a bid before FIFA formally open the process in 2022," read a joint statement on Monday from the five British Isles football associations.
"Staging a FIFA World Cup would provide an incredible opportunity to deliver tangible benefits for our nations.
"If a decision is made to bid for the event, we look forward to presenting our hosting proposals to FIFA and the wider global football community."
FIFA is planning for its congress of 211 football nations to pick the 2030 host in 2024.
A rival bid in Europe is being pursued by Spain and Portugal and UEFA wants a single proposal from the continent. There is also a coalition of South American countries pushing ahead with a bid from Argentina, Uruguay, Paraguay and Chile.
China could also bid if FIFA changes its rules on the rotation of World Cup hosts with the Asian Confederation also staging the 2022 edition in Qatar. The continent's turn on hosting is not due to come again until 2034. The 2026 World Cup will be jointly hosted by the United States, Canada, and Mexico.
The 2018 bidding process was mired in controversy with many of the voters later embroiled in investigations or banned. David Cameron, who was British Prime Minister at the time of the 2010 vote, said "the corrupt undertones were all there."
During the World Cup bidding, FIFA was led by Sepp Blatter who was later banned from football for six years by the FIFA ethics committee after being forced from office in 2015.
Cameron said the corruption at FIFA reflected an issue "that proved to be more prevalent than I had expected."
"Those same forces that had denied Britain the World Cup," Cameron wrote in his 2019 autobiography, "bribery, lack of transparency, collusion, fraud were depriving people around the world of safer, healthier, wealthier lives."
FIFA has been led since 2016 by Gianni Infantino. A special prosecutor in Switzerland last year recommended opening a criminal investigation against Infantino, who denies wrongdoing.
