I wonder what the pricing and tax regime for gas will be medium term. The gas companies will want to offload their production at a price which still makes the choice between gas and electricity come down in favour of gas, but I am speculating that just as with diesel which used to be very much cheaper than petrol, then became more expensive, over the coming years burning gas in domestic homes, will become more expensive than the "greener" alternative of electricity.1 . If it doesn't then nothing is going to change very quickly from the status quo.
In my opinion there is too much political capital and prevailing science invested in the process of change to allow that to happen.

1 yes...electricity is only as "green" as how it is generated
