Making the announcement at this week’s IMEX Frankfurt, the 10 congresses alone are estimated to generate £250 million to London’s business economy, in addition to the £4.6 billion Excel brings annually through its 400-strong event calendar.
The congresses, the majority of which utilise Excel’s new state-of-the-art 25,000sqm ICC Expansion, include the EAU Congress in March, the FTTH Conference in April, the INTA 2026 Annual Meeting from 2 to 6 May, the ESHRE 2026 Annual Meeting in July and the EuMW 2026 at the beginning of October. In total, the congresses are expected to attract some 80,000 delegates to the UK capital, many of whom will be from overseas.

Built to leading BREEAM sustainability standards, Excel’s £220 million expansion development – fully supported by ADNEC Group – will increase the venue’s existing world-class facilities by a further 25%, totalling 125,000 sqm (1.3m sqft) – and making it the largest fully integrated conference and exhibition centre in Europe.
Offering stunning views of London’s skyline, the expansion gives Excel an additional International Convention Centre, together with ultra-modern exhibition halls, conference spaces and breakout rooms. With the finishing touches now being made, the first official event in Excel’s new space will be the all-electric Formula E motor racing series at the end of July.
