Energy Suppliers: Customer Credit

I am grateful to my hon. Friend for giving way again. I am taking advantage of the time that we have, Mr Betts—I apologise for the number of interventions, but this is an important point to clarify. The point he makes about having a fair mechanism in place to ensure that people are not being treated punitively over their credit balance is important. I hope the Minister will look at that to ensure that people are protected.
