7p looks a tad optimistic, but only a tad - https://energy-stats.uk/wholesale-energy-pricing/ https://energy-stats.uk/wholesale-energy-pricing/ That I'm aware of, the "wholesale cost" does not include the local distribution networks. Those cost a fair number of pence to build and maintain. And - I vaguely recall that the UK had world-beating taxes and surcharges on electricity - some for "green" reasons, some to spread the agony of the staggering cost overruns at new British nuclear plants, and some to help shore up the government's "general budget" financial woes.
