As Dale Vince (Ecotricity) points out, all that is required to reduce energy prices (specifically electricity) in the UK is to remove the requirement from the auction system that the price is dictated by the highest bid (nearly always that made by gas).
Breaking the link with gas prices (and allowing each energy source to be supplied at its actual bid price) would immediately reduce energy prices across the country.
Moreover the Govt. has the power to do this, they just don't!
