We provide strategic, practical and expert economic regulatory advice and assistance to regulated businesses, regulators and new entrants operating in traditionally regulated markets.  We offer specialist governance, facilitation and project management support for pricing and other economic regulatory submissions.

We provide independent expert economic opinions; practical assistance in preparing documentation; training on writing and modelling for regulatory proposals; strategic advice on approaches to determining the cost of capital, incentive scheme design, pricing and customer engagement; and assistance to develop and implement stakeholder engagement strategies. We also help businesses and regulatory bodies to understand the practical effects of regulation, and how market and technological changes affect regulatory and commercial strategies.

We assist government, businesses and regulators with the development and implementation of policy across a wide range of infrastructure sectors. We have deep experience in energy policy and utility sector economic reforms. Our advice is informed by having held senior roles in governments, regulators and rule makers. Drawing on our commercial and public policy experience, we ensure the right focus and balance of change. We also provide policy advocacy support for businesses.


We assist clients to apply a range of quantitative tools including financial, regulatory, pricing and economic models. We look for innovative solutions to complex problems, ensuring that these are user friendly and accurate, and follow best practice. We have a deep understanding of regulatory and broader modelling, the applicable rules and precedents, and the value levers these offer to infrastructure service providers and economic regulators.

Regulated rate of return strategy

Rate of return estimation is a complex – and regularly disputed – area of regulatory practice that is often in need of clear, targeted and evidence-based thinking.
