Cornwall offers comprehensive energy supplier compliance assessments to examine supplier retail activities against customer-facing GB licence and regulatory requirements.

Assessments are tailored to customer specifications, but can include complete examinations of all customer documents and website materials, and all customer facing interactions and processes.

Each assessment examines practices against the requirements of the supply licence and government legislation, as well as industry best practice. Where any potential non-compliances are identified,  recommendations. Examples of compliant actions are also provided where relevant and available. Each report includes a traffic light rating system to help prioritise changes that may need to be made.

For more information on the Assessments please contact Adam Boorman at a.boorman@cornwall-insight.com or 01603 604417.
