The 2015 Rugby World Cup generated £2.3 billion in economic output, making it the most economically successful Rugby World Cup in history.
According to the report by EY, roughly half of the total was added directly to UK GDP, with 2.47 million tickets sold, 406,000 international visits from 151,000 nations boosting tourism across the UK's host cities, and 34,000 jobs created or supported.
The average international visitor spent £2,400 on a 14-day trip to the UK, with 80% describing their experience as "exceptional", and the same amount saying they would come back. In total, EY said international visitors spent £958 million in the UK.
£270m of this was spent on accomodation, ahead of leisure activities on £233m. Visitors spent a further £188m on food and drink, £156m on travel and £111m on retail.
A further £2.7bn was generated through inward investment directly related to the Rugby World Cup.
The 15 fanzones around the country were also a big hit with both international and domestic fans. They not only created an incredible atmosphere, but provided a key focal point for the tournament in each city. More than one million people attended a fanzone, including 265,000 international visitors, who spent an average of £40 in the fanzones contributing a total of £10 million to local economies.
World Rugby chairman, Bernard Lapasset, said: "Rugby World Cup 2015 was a very special and record-breaking global celebration of rugby and its character-building values and widely regarded as the biggest and best Rugby World Cup to date.
Ian Ritchie, CEO of the Rugby Football Union, said: "We wanted Rugby World Cup 2015 to be a celebration of rugby, which inspired the country, and the world, to play and support the game. The team at England Rugby 2015 and the RFU are proud of the tournament we organised and hosted, which will deliver valuable financial benefits not just for the game of rugby, but for the wider national economy."
EY Executive Director Mike Grice said: "EY is proud to be the official business advisor of Rugby World Cup 2015, and our report demonstrates the truly national impact of RWC 2015. There were a large number of international visitors to host cities outside London, including Birmingham, Brighton and Manchester. Many visitors extended their stays over several days or even weeks, to watch several matches in a variety of different venues. Host cities also gained exposure to international markets, raised their international profiles and encouraged future tourism.”
