British Gas will have to live with the fact that many of their customers won't be jumping for joy over this news.
The wholesale market has been dropping for months, with wholesale costs for the next 12-month contracts down 28%.
In that context, this 5% drop can look a little bit mealy-mouthed.
The remaining big six companies that have not dropped prices yet have not given any firm signals that they will reduce prices.
If you look at when British Gas raised its prices by 35% in 2008, the new tariff came into force with immediate effect.
Today's reduction won't come in until the end of next month - some people will see that as an unfair contradiction.
