You might find the crossover for hot water heating is higher than 0p; your boiler is likely only around 70% efficient. So at 6p/therm for gas, you'd break even with resistive electric heating at around the 10p/kWh mark.

You should absolutely re-run these numbers to be sure, but you might find you can use electric heating far more often than you might currently be doing.
