In principle, competition should drive down costs. In practice, it doesn't. Just look at the cosy cartels - supermarkets, banks, oil companies, big breweries, etc - who pretend not to be acting in concert whenever they put their prices up. It's even worse in the energy sector because the regulator is weak and there's essentially no genuine competition.
We're also paying extra on our bills to subside the staggeringly high costs of building new nukes. Which are going to get a 30-50 year licence to print money once they come on-stream. No market forces at work there at all.
