The Financial Conduct Authority has scrapped the seven-day waiting period for connected research during initial public offerings, as part of reforms designed to make London a more attractive venue for companies seeking to list.

The changes, which came into force on 5 August 2026, also simplify information-sharing requirements between issuers and financial firms during the IPO process.

The regulator said the reforms would reduce execution risk for companies going public and lower compliance costs, addressing longstanding concerns that UK listing rules had become overly burdensome compared with rival markets.

Jon Relleen, director of infrastructure and exchanges at the FCA, said the changes were intended to make the UK listing regime more efficient and support the competitiveness of UK capital markets.

The new rules follow a consultation paper published earlier this year. Full details are set out in Policy Statement PS26/16.
