• Support engagement with Government, Ofgem, and other relevant industry bodies.

Candidate profile:

We are looking for someone who has:

The following would be advantageous:

• Familiarity or experience with energy policy or energy markets (particularly energy flexibility / demand side response).
• Understanding of, or an interest in, customer assurance and protection.
