FCA Warns Firms to Prepare for UK T+1 Settlement in 2027

The Financial Conduct Authority has reminded UK market participants that the move to T+1 settlement for securities trades is approaching, with the new cycle scheduled for 11 October 2027.

In a 13 August blog, the regulator said the shift is a fundamental change for post-trade operations. Firms will need to complete matching, allocation, funding and settlement work faster than under the current timetable. The FCA said some firms are more advanced than others, while some still have a lot to do before the deadline.

The regulator has been speaking with buy-side firms, sell-side firms, market infrastructure providers, third-party service providers and trade associations as part of its readiness work. Its message is that T+1 is not only a compliance project. It is also a chance to reduce settlement risk and make the UK market more efficient.

Why it matters

For traders, shorter settlement changes how quickly cash and securities move after a trade. Brokers and platforms with weak post-trade processes may face more settlement pressure, especially around corporate actions, cross-border holdings, currency funding and end-of-day instructions.

The change also matters for active equity traders who depend on fast account updates, reliable buying power calculations and accurate settlement status. Operational delays can affect withdrawal timing, margin availability and the ability to reuse funds.

What to watch next

Watch for further FCA readiness updates and firm-level implementation plans ahead of the October 2027 deadline. Traders comparing UK brokers should pay attention to settlement disclosures, funding cut-off times and how platforms handle failed or delayed settlements.
