The Arbitration Act 2025 (“AA25”) came into force on 1 August 2025 and applies to any arbitration commenced on or after that date and any court proceedings, unless they relate to an arbitration commenced before that date. The AA25 works by amending provisions of the Arbitration Act 1996 (“AA96”), which is now a 30-year-old piece of legislation. The implementation of the AA25 seeks to reenergise London’s offering as a key seat for international arbitration and brings some substantial developments.
