British Gas are "brave" for hosting an online question and answer forum on the day of their latest price hike, consumer group Which? said.
Twitter users have already been sending messages to the company, before the session has even begun.
Our Customer Services Director Bert Pijls will be taking part in a Q&A about our price rise at 1-2pm. Tweet your questions using #AskBG!
One user posted a picture of an old woman wrapped in blankets and huddled next to a heater, writing: "Do images like this help you sleep at night Bertie?".
Another said: "Hey @BritishGas how many vulnerable people do you think you will push into fuel poverty whilst continuing to make billions in profit?".
Tweeter Alan Gibbs added: "My parents 89 & 82 want to know more about the early signs of hypothermia, especially with the winter coming on."
