"Having looked at the matches that we have and the venues we have we are confident we are going to be able to honour the minimum access prices that there were. There is certainly a commitment from us to be able to do that."
Organisers were keen to stress the perceived rugby legacy of England hosting the event, insisting the financial demands were only part of the story. "The most important thing is to inspire people to play rugby," said Ian Ritchie, chief executive of the RFU. "We are comfortable about the financial side but it is subordinate to the legacy."
The need to ensure large attendances, and the number of seats offered by Wembley, Twickenham and the Olympic Stadium, means that much of the tournament will be focussed on the south-east, although there is a geographical spread during the pool stages with games scheduled for Exeter, Newcastle, Leeds and Leicester as well as eight at the Millennium Stadium - second only to Twickenham's 10 games.
Twenty two of the 48 games will be in the south-east - 17 in London - while England's final pool game at the Etihad Stadium will be the sole fixture in Manchester. Organisers rejected claims that the tournament is overly concentrated on London and the south-east.
"Whilst yes we do have three big stadia in London we have also taken it through the whole of the country and we are proud of that fact," said Jevans. "The ambition was absolutely to take the event to the northwest and Manchester and we never at any point had a large number of games [planned for] that region. The important thing was we wanted to take England to the northwest. I don't think it is a problem."
The Welsh Rugby Union are possibly the biggest winners with Wales playing two of their pool games there as well as receiving much needed income from hosting six other matches, including two quarter-finals.
Agreeing the schedule, with the use of seven club football grounds, has also involved delicate negotiations with the Premier League and the Football League. The Rugby World Cup organisers are all too aware the tournament, which runs from England's opening Friday-night game on 18 September to the final on Saturday, 31 October, runs in competition with the football season. "The whole of our plan has been to minimise impact on the football schedule," said Jevans, formerly director of sport for the London Olympics.
Lawrence Dallaglio, an ambassador for the tournament, insists rugby should not be "threatened" by football. "People have to appreciate this is the third biggest sporting event in the world," said Dallaglio.
The organisers' ambition is bold, not just in the number of seats in 13 stadia it aims to fill, but also the impact it wants the tournament to have on this country's sporting landscape. "We want England to feel like a rugby nation in 2015," said Jevans, drawing parallels with how 1966 is recalled. "We want 2015 to be a rugby year."
