Evidence-based Analysis for Fair, Accountable Regulation

Our work supports regulators and utilities in designing, reviewing, and defending decisions that shape the performance and stability of essential services. We provide rigorous economic and financial analysis to address regulatory challenges, from the cost of capital and financeability to tariff design, benchmarking, and investment appraisal. Our goal is to ensure that every regulatory framework is transparent, proportionate, and grounded in sound economic principles. We provide independent advice across the full regulatory cycle, including design and review of price control frameworks and revenue models, tariff structure and benchmarking analysis for network operators and utilities, cost of capital (WACC) estimation and financeability assessments, regulatory accounting and audit reviews, as well as policy and market assessments to support reform and performance evaluation.

I am delighted to recommend PJ and his team at MCC Economics. We've been working together on National Policy Statements to help meet net zero targets for 2030 and 2050. We initially appointed to support us on offshore wind consultation analysis and have recently reappointed MCC Economics to undertake a larger consultation analysis role across all sectors, including hydrogen, CCUS and networks.

I am delighted to confirm that I worked with PJ on a retail project in 2015. The project helped stakeholders understand electricity costs and charges. Specifically, the project helped us explain to stakeholders, internally and externally, why electricity charges differed across the regions (GB, NI & Ireland). PJ was a key member on the project team, which helped deliver changes and improvements in the understanding of energy retail.
