design and implement (d&i) is a specialist regulatory consultancy, founded in  July 2002 by Andrew Jackson and John Bennett who have extensive experience of utility reform and continue to work as its main consultants.    We have extensive experience in the deregulation of wholesale and retail utility markets in the UK, Europe and Australia providing expert advice on the design, development, and regulation of competitive utility markets (primarily in the electricity and water sectors).  Both have held senior positions within market reform programmes, and worked for a diverse cross section of clients within reform processes and established liberalised markets including Government departments, market participants, regulatory bodies and customer groups.

Our practice has been to work with a smaller number of clients over extended periods - in a number of cases over several years.  Such assignments reflect both the value of the services we provide, and also close working relations that we have with our main clients.

Our three main areas of service are:

Market design, development and implementation

Advising to policy makers in the design of competitive market structures and support in their effective implementation with an emphasis on the electricity and water sectors.

Regulatory Advice

Assisting Regulatory Authorities with the formulation of regulatory policy, the preparation of consultations, leading discussions with industry and broader stakeholders on regulatory change.

Commercial strategy

Supporting companies in developing commercial strategies to compete successfully in liberalised utility markets.


We provide modelling and market analysis to support each of these service areas.
