Those answers won't be too helpful. We have very high bills compared internationally, due to a difficult-to-explain quirk (pay-as-clear marginal pricing) where all electricity is charged to the customer at the highest rate possible at that moment. So wind may cost 0.05 pkwh and be freely available but if gas is being utilised anywhere else in the grid at a cost of eg. 0.45 then everybody gets charged 0.45 pkwh, even for the wind energy.

Its a messed up system which means often pay the highest in Europe, without even helping that much towards the tax coffers. But reform of this system does seem to be gaining a bit of political momentum.
