Paybacks from UK renewables could cut £27 from bills by end of winter

140 might have been knocked off typical bill if rollout of projects had happened sooner, says industry

Britain's wind and solar farms could help to reduce households' energy bills by paying back almost 800m to consumers by the end of the winter after gas and electricity market prices rocketed above their set subsidy levels.

Households earned a 157m windfall from renewable energy generators for the first time in the final quarter of last year following record high market prices, according to official figures.
