The International Convention Centre investment at Excel in Royal Docks has generated £5billion for London’s economy since the facility opened in 2010.

The figure is contained in a recently published study by professional services firm Grant Thornton and excludes the part the venue played in the 2012 Olympic and Paralympic Games.

Excel said its conference and events revenues had doubled over the period and its ICC expansion had helped push the capital from 19th to sixth in the International Congress and Convention Association worldwide rankings.

The venue’s executive director James Rees said: “Opening the ICC at Excel was the right decision, not only for us, but for London.

“In 2008, with the endorsement of Mayor of London Boris Johnson, we committed to build and open London’s first truly International Convention Centre.

“At the time London was 19th in the ICCA rankings but we recognised the economic benefit that hosting more ICCA-rated events and large scale corporate conventions would bring to the capital.

“With the support of our owner – Abu Dhabi National Exhibitions Company – the £165million ICC was opened in May 2010 and allowed London to bid for and host major international congresses and events for the first time.

“Five years on, with London now sitting at 6th in the ICCA rankings, we are able to provide organisers with the assurance that by choosing London they will be working with a city that understands their business and can help them to deliver record-breaking, profitable events.”

He said large conventions had a positive effect on the whole of the capital with smaller events being held in hotels, universities and other venues across the city as a result.

The Excel centre said 2015 had been its busiest year with conferences and events including the European Society of Cardiology, Microsoft Future Decoded and the Adobe Summit all taking place in east London.
