You're assuming that the energy costs of pumping gas to your home rather than to the power station are less than the generation/transmission losses for electricity, and also that there isn't any difference in the efficiency of burning the gas at the power station and in the home. I'm sure it's the case (that using gas directly is better) but it does need to be considered.
Also, if you actually care about CO2 emissions rather than energy usage, then the story for electricity becomes rather more complicated.
