Get your last gas an electric bills and compare the "unit" (kWhr) rates
for gas and electric. Gas I would expect to be about 5p/unit (+/- 3p),
electric 12p/unit (+/- 6p). The rest is just maths and some
guesstimations, the only real way to be sure would be to use one method
for a week then the other taking meter readings at the start and end of
the periods. You may also need to take into account the weather, if one
week colder than the other...

Gas is much cheaper so the system would need to be losing more than
half the heat for electric heating to win. Also it's a more
comfortable environment than sitting looking at an electric fire.

Turn the gas on.
