Under the Marginal Pricing model, energy suppliers set prices based on the highest-cost energy source used, which in the UK is gas. Even though energy suppliers may buy cheaper renewable sources first, they must also rely on pricier fossil fuels to meet demand. Therefore, the final price paid by consumers reflects the cost of the most expensive source used.

Feels like we should abolish this system. Not sure why it even exists, as to me the price should be based on the cost. As things stand we are just giving free money to energy companies and worse petrol oligarchs.

I recognize that we will likely always need some fossil fuel energy in the UK to pick up the slack, but why are the savings of investing in renewables not making their way to the consumer?
