British Gas Fixed Tariff?

I heard a bit of a programme on the radio recently - (in the car so missed the start and finish) but a caller said that he had the gas capped to his house and intended to go All-electric. All gas appliances had been removed. His problem was that he still had to pay a standing charge for gas to the house, even though he couldn't use it. Don't know what the outcome was but I have thought about changing from a gas boiler and the 2 burner gas hob to all electric heating with wood fire.
