Among the headline events shaping June’s bustling business calendar are SXSW London, the 2025 Concordia Europe Summit, London Tech Week, and London Climate Action Week
London is gearing up for what the Mayor has described as the “biggest ever” month for business and investment, with June set to host a series of major international events that will bring thousands of business leaders, innovators, and creatives to the capital. This surge in activity underscores London’s enduring reputation as a global hub for economic, cultural, and technological excellence.
Among the headline events shaping June’s bustling business calendar are SXSW London, the 2025 Concordia Europe Summit, London Tech Week, and London Climate Action Week. Together, these four gatherings promise to draw dealmakers, CEOs, entrepreneurs, and forward-thinking professionals from across the world, further cementing London’s status as a leading destination for commerce and innovation.
The Mayor of London, Sadiq Khan, highlighted the city’s prime position for growth in light of recent UK trade deals with key partners including India, the US, and the European Union. He said, “There has never been a better time to invest in the capital.” Khan also noted the shifting political landscape in the US, which has created opportunities for London to attract businesses seeking stability and growth in a pro-investment environment.
Supporting these ambitions are new figures released by London & Partners (L&P), the city’s growth agency. The data reveals that L&P secured over £677 million in trade and investment in the last financial year alone. This included £484 million generated by helping London’s technology companies expand internationally and £134 million from foreign direct investment, representing the highest sum L&P has secured in a single year. These investments are expected to create up to 5,000 new jobs in London over the next three years.
London’s economic might is immense. Its total output was £531 billion in 2023 — more than 20 per cent of the entire UK economy. To put this in perspective, the capital’s economy rivals the combined economic output of both the South East and North West regions of England.
A Month of Major Events
June will kick off with SXSW London, running from June 2 to 7. This is the inaugural European edition of the famed SXSW festival, which brings together leaders from the tech, media, and creative industries. Speakers include prominent figures such as Sir Demis Hassabis, Co-Founder of Google DeepMind, and Ben Lamm, CEO of Colossal Biosciences.
Following closely is the 2025 Concordia Europe Summit, scheduled for June 8 to 10. This invitation-only summit gathers global business executives and political leaders to discuss economic growth and the role of financial institutions in fostering entrepreneurship. Notable attendees include Francesca Carlesi, UK CEO of Revolut, Cherie Blair, co-founder of Omnia Strategy LLP, and former Croatian President Kolinda Grabar-Kitarovic.
London Tech Week, Europe’s largest technology event, takes place from June 9 to 13. It will bring together innovators, investors, and tech leaders shaping the future of industries. Attendees include Jimmy Wales, founder of Wikipedia, Mark Read, CEO of WPP, and Melanie Dawes, CEO of Ofcom.
Finally, London Climate Action Week from June 21 to 29 aims to unite businesses, politicians, NGOs, and climate experts to address environmental challenges and promote sustainable solutions.
Mayor Khan stated, “London is the best city for business in the world — an economic and cultural powerhouse bristling with creativity, innovation and enterprise. We are the engine of the UK economy — the top destination in Europe for inward investment, and a top two global financial centre.”
Laura Citron OBE, CEO of London & Partners, emphasised the city’s competitive edge. “Global competition is tough and getting tougher — whether it’s competition for London to win investment or competition for our entrepreneurs to build global companies. For every £1 of public investment into our organisation, we generate £27 in the London economy.”
Max Alexander, CEO of SXSW London, praised the city’s unique strengths: “SXSW London reflects London’s exceptional creativity, technology, and international collaboration. This June, we will gather the boldest minds in tech, media and the creative industries to drive ideas, deals and growth.”
Matthew Swift, co-founder of Concordia, called London “a hub for finance, innovation and diplomacy, and the perfect setting to convene leaders from the public and private sectors.”
Carolyn Dawson OBE, CEO of Founders Forum Group, said, “London has long been the gateway to the UK’s dynamic tech ecosystem — a launchpad for innovation, investment and impact.”
Howard Dawber, Deputy Mayor for Business and Growth, summed it up: “Now is the time to invest in London. June will showcase our great city to the business world in all its glory.”
