The nuclear crisis in Japan will force up UK gas prices and have a knock-on effect on energy bills, say experts. The Fukushima nuclear power plant was among 11 of Japan's reactors to be shut down in the wake of the earthquake and tsunami disasters, increasing demand for liquefied natural gas. Adam Forsyth, analyst at Matrix Group, said: "If the price rises and is consistently at a high level then it has to come through to people's gas bills eventually."
