British Gas has made what should be a routine billing procedure into a number-crunching hell hamstrung by a labyrinth of inconsistent bills and unresolved technical difficulties. We switched to a direct deposit some months ago to keep from getting wildly varied bills every three months. Everything was going smoothly until two of our flatmates decided to move out, so I asked for a refund on our credit to pay them back for energy they wouldn't end up using. The reps confirmed we could do that until our Electricity Meter inexplicably stopped sending data and said we used more electricity in six weeks in the middle of summer than we did throughout the entire winter! During that period our flat was nearly empty, and we have not high-power appliances running. Not only did we get with a MASSIVE bill, but they said they can't do anything about it until the meter is fixed. That was two months ago and we are still waiting for them to send an engineer despite our issue being made "priorty." This word has lost all of its meaning. Avoid this company at all costs. They are more than happy to allow customer problems go unresolved so long as it makes them more money.
