Scott Devereux | CEO | Earl Shilton Building Society
Overview
The Treasury Select Committee highlighted the extent and impact of failed change initiatives at banks and building societies in 2025. We've delivered, advised and assured almost 30 core banking, cloud migration, web and mobile changes. We don’t accept the idea that every transformation is delayed, descoped, or over budget.
Leadership often recognise that things need to change and have created the vision, case for change and co-created the delivery plan with third parties. They've set themselves an ambitious goal to put their colleagues in a position to provide their customers / members with proactive and personalised services in the moments that matter most.
Commonly the changes focus on streamlining colleague and customer / member journeys, creating a single customer view, offering dynamic products such as lending for those that are not the 'perfect borrower', and creating a simpler and more transparent journey for brokers. The technology, risk and resilience challenges often need to be addressed in parallel, such as siloed systems and reducing reliance on tightly coupled legacy systems that make any type of transformation difficult.
Stakeholders (including regulators) expect that the board should provide oversight of all significant (sometimes known as ‘material’) change initiatives. For example, those changes that have a high operational, regulatory and / or customer impact should they fail.
Approach
We don't do cookie-cutter and tailor our approach to meet your exact needs. This goes beyond early risk identification and opportunities to accelerate value; it’s about applying an evidence-based approach that instils decision making confidence throughout the change journey, delivering a proportionate risk reduction plan that eliminates surprises. To be effective, that approach requires vendor independence, audit discipline and credible delivery experience to support decision making.
We bring a senior led approach and deep subject matter expertise in the key areas of risk that you face. We advise on potential risks, hidden opportunities to accelerate value, change implications, while also providing guidance and direction.
We often support this with ongoing coaching for board members to improve their ability to ask the right questions of management and suppliers, focusing on developing a baseline understanding for all board members.

Challenge
A Building Society embarked on a major transformation designed to streamline member journeys, modernise legacy systems and enable colleagues to deliver a more proactive, personalised service.
The vision was clear and the business case was compelling. But the Board and Executive recognised the risks. The Treasury Select Committee had recently highlighted the scale of failed change across the sector. The PRA's 2026 priorities placed renewed emphasis on operational resilience, data quality and board accountability. Recent Dear CEO letters reinforced expectations around governance, risk culture and forward-looking risk assessment.
With multiple dependencies, legacy constraints and high member impact if things went wrong, the Society needed independent assurance that was senior-led, evidence-based and aligned to the rising regulatory bar - something they could rely on in delivery and in discussions with regulators, auditors and their own governance committees.
Approach
A senior-led, experience-driven assessment that combined delivery expertise with audit discipline, aligned to the themes emerging from Parliament and the regulators. Rather than templates or generic maturity models, the focus was on the realities of the change - the decisions being made, the risks being carried and the evidence supporting progress. A clear, evidence-based view of delivery confidence was built through targeted interviews, review of delivery artefacts and triangulation against existing assurance - without duplicating effort or creating unnecessary burden.
Early visibility was provided on emerging risks, hidden opportunities to accelerate value and the practical implications of key decisions. The Board received coaching to strengthen their ability to challenge suppliers and management, ensuring they could fulfil their oversight responsibilities with confidence and in line with regulatory expectations.
Throughout the engagement, the change was assessed against the expectations now shaping supervisory scrutiny:
Outcome
Critical delivery, technology, data and resilience risks were surfaced and addressed early - before they could escalate into delays, outages or member harm. Management had the evidence to make informed decisions at each major stage gate. The Board, regulators and internal audit had confidence that the transformation was on a safe and controlled path.
As risks were mitigated, delivery confidence strengthened. Stakeholders had clarity on what mattered, where to focus and how decisions would influence outcomes. The programme became more predictable, more transparent and fully aligned to the expectations now shaping the sector.
The Board had confidence. The regulators had evidence. And the members the Society exists to serve were protected.
