BANKING

Operational Resilience for UK Banks. DORA-Ready. PRA SS1/21-Compliant. Board-Ready Evidence Delivered.

We help challenger banks, digital banks, and specialist lenders build the operational resilience evidence that satisfies PRA and FCA supervisors - and the DORA obligations now applying to firms with EU-connected operations. IBS mapping, ICT resilience, supplier exit testing, and regulatory-grade evidence packs. Senior-led throughout.

The operational resilience challenges facing UK banks vary significantly by firm type. Here is where they diverge.

Firm Type Primary Resilience Challenge
Challenger and digital banks Typically strong on technology architecture and ICT resilience, but with BCM documentation and regulatory evidence quality lagging behind the pace of firm growth. The most common gap is not the programme itself — it is the evidence that the programme is genuinely embedded and tested. PRA supervisors entering the first full supervisory cycle with these firms are specifically testing for evidence depth, not framework existence.
Specialist lenders and deposit-takers Often carry concentrated IBS dependency on a small number of critical technology platforms and third-party service providers. Supplier exit planning and ICT continuity frameworks are frequently underdeveloped relative to the concentration risk they carry. PRA SS2/21 requires tested exit capability; most specialist lenders have documented intent rather than evidenced feasibility.
UK subsidiaries of international banks DORA obligations apply where the firm has EU-regulated entities or material EU-serving operations — and many UK subsidiaries of international banking groups fall within scope without having confirmed this formally. The challenge is twofold: establishing whether DORA applies to the specific UK entity, and if so, aligning ICT risk management, third-party oversight, and incident reporting to DORA requirements that differ in structure from PRA SS1/21.
Dual-regulated private banks Private banks carrying both banking and insurance authorisations — or banking and investment management permissions — face the most complex IBS identification challenge. Services must be mapped across both regulatory perimeters, impact tolerances set against potentially different supervisory standards, and scenario testing programmes designed to satisfy two sets of supervisory expectations from a single programme.

Banking Industry Regulatory Requirements and Challenges

What your regulator requires

  • PRA SS1/21 - the embedding and evidencing phase is now the active regulatory focus. PRA supervisors are testing for the depth and quality of resilience evidence, not just whether a framework exists. Firms entering their first full supervisory cycle are most exposed.

  • DORA - for banks with EU-regulated entities or material EU operations, DORA requirements on ICT risk management, third-party oversight, and incident reporting have been in force since January 2025. Most mid-tier banks are still in remediation or validation phase.

  • PRA SS2/21 - ICT and technology resilience for banks. Requires firms to demonstrate that technology systems supporting Important Business Services can recover within impact tolerance.

  • FCA SYSC 15A — operational continuity in resolution. Applies to dual-regulated firms and requires evidence that the firm can maintain continuity of critical services in a resolution scenario. 

What FourthLine delivers for banks

  • IBS identification and validation - mapping critical services against PRA supervisory expectations, not internal definitions
  • Impact tolerance setting - metric-based, stress-tested, board-ready
  • Annual scenario testing programme with regulatory-grade evidence pack
  • DORA ICT risk management gap assessment and remediation programme
  • Third-party risk management and supplier exit testing - DORA Article 28 and PRA SS2/21 aligned
  • ICT service continuity framework and DR plan validation against IBS impact tolerances
  • Supervisory preparation - board-ready evidence pack before the PRA review, not during it 

Want the full picture on banking sector operational resilience and DORA in 2026?

We have written a focused briefing for UK banking firms covering the PRA's current supervisory approach to SS1/21 evidence, what DORA actually requires from UK-domiciled banks with EU operations, and the supplier exit testing obligations most mid-tier banks have not yet addressed.
