Assure. Advise. Deliver.

Risk reduction, business improvement and complete regulatory alignment.

Green Dolphin provides change assurance in building societies.

Independent Change Assurance

The Treasury Select Committee highlighted the extent and impact of failed change in 2025.  We've delivered, advised and assured almost 30 core banking changes. 


This goes beyond early risk identification; 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.

Green Dolphin TCCR provides cyber risk audit and assurance in building societies.

Cyber Risk Management

The latest Bank of England Systemic Risk Survey highlights cyber risks are evolving and budgets remain finite. 


We've supported over 50 banks, building societies and insurers to understand their changing risk exposure, finding a proportionate approach to protect operational resilience, without unnecessary spend or blocking innovation.

Green Dolphin TCCR provides technology and cyber risk audit and assurance in building societies.

Technology Risk


We bring CTO, CISO and Head of Tech Risk experience, giving technology, operational and change leaders the support they need to simplify technology risk and provide clarity.


This includes strategy and operating model, risk and governance, cloud and infrastructure, development and operations, service management, third‑party and outsourcing.

Green Dolphin TCCR provides operational resilience and scenario testing in building societies.

Scenario Testing


The latest Dear CEO Letter in January 2026 continues to prioritise the importance of testing your defences to protect operational resilience.


To ensure readiness, we've facilitated dozens of training sessions and conducted crisis simulations at banks, building societies and third parties. These exercises help identify weaknesses and improve your response capabilities. 

Green Dolphin TCCR provides internal audit and risk team support in building societies.

Internal Audit and Risk Support

As chair of the UK’s Chartered IIA IT Audit Group, we're trusted and can provide co-sourced support for your audit or risk team.


We provide training, cross sector benchmarking, and deep technical expertise to compliment your own team,  ensuring your reviews deliver the right outcomes and trusted assurance.

Green Dolphin TCCR provides SWIFT, LINK and PSD2 support  support in building societies.

Payments and Open Banking

Payments continue to drive a high proportion of operational incidents.  


With over 20 certifications and attestations delivered across banks, fintechs and building societies, we bring proven expertise in SWIFT, LINK, PCI DSS, PSD2 and Open Banking.

Green Dolphin TCCR provides change assurance, advisory and audit  support in building societies.

Change Delivery


We seamlessly integrate into your own team to provide hands on support, helping you deliver change outcomes.


Our strengths lie in business analysis, customer‑journey mapping, agile delivery and practical change management - the essentials needed for change to land well with colleagues and customers.

Green Dolphin TCCR provides AI audit and data governance  support in building societies.

Data / AI Governance

Poor data is a prudential risk that can undermine resilience, capital adequacy, and customer outcomes.


We provide data / AI assurance with independent challenge on model risk, security and governance that ensure systems are safe, compliant and fair.

Third Party Risk

The Treasury Select Committee's 2025 findings were unambiguous. Reliance on third parties, from core banking platform vendors to cloud infrastructure providers and payment processors, sits at the heart of the operational resilience challenge.


Our approach is tailored, proportionate to the risks faced, the regulatory obligations in scope and the commercial reality of the firm. 

Green Dolphin TCCR provides technology and cyber due diligence support in building societies.

GRC Support

Your teams understand your risks, controls, and governance processes better than anyone.  


We provide a clear, independent view of the GRC tooling landscape - what genuinely strengthens governance and what will actually work rather than simply digitising existing processes.
