Energy companies have greatly improved the way they find and manage priority service customers and those who have special needs and are vulnerable. I still don’t think it’s enough.

First, from the customer point of view we are all vulnerable sometimes. So many events – a broken leg, say, a baby, even untimely weather – can have much greater effects than anticipated and be temporarily devastating. I am sure the thousands of Carillion employees whose jobs are under threat feel very vulnerable, even if they don’t fit that profile on paper.
