Based on input from more than 600 market participants, these key findings examine how UK readiness is evolving as firms move closer to T+1 execution. The findings show strong engagement, but uneven development work and continued concern over service provider readiness.

UK leads on engagement

Engagement

The UK is the most advanced market in the study on engagement, but execution risk remains.

This is up from 66% in Q3 2025.

Development work is still missing

Readiness

The key gap is no longer awareness. It is practical delivery.

Only 14% consider themselves compliant or fully prepared.

Provider readiness is weak

Dependency

External readiness remains one of the clearest execution risks in the UK market.

34% of firms are also expected to miss the 2026 deadline for allocations and confirmations.

Switzerland is preparing early

Engagement

Despite a later start, Swiss engagement is already strong.

The market is moving decisively into preparation ahead of the 2027 deadline.

Automation is concentrated in 2027

Delivery

A significant share of build activity is still scheduled close to the deadline.

This makes execution timing an important focus from here.

Recommendations are on track

Implementation

The policy framework is largely expected to be in place before the transition date.

Market operator readiness remains more mixed.

UK readiness for T+1 is advancing, but execution risk remains. Engagement has increased sharply since Q3 2025, making the UK the most advanced market in the study, yet important parts of the operating model still remain underdeveloped.

How prepared is the UK market in practice? Where are firms still relying on future delivery, external readiness and milestones that have yet to be secured?

These key findings draw on input from more than 600 financial services professionals globally. The UK findings show how readiness is progressing as the market moves closer to implementation, and where dependencies continue to create pressure across the buy side and wider market structure.
