Britain's electricity is greener than ever. Your bill hasn't dropped. That's not bad luck — it's a scam built in 1990, maintained by lobbying, and costing you hundreds a year.

The UK runs on marginal pricing. The most expensive generator running at any moment — almost always gas — sets the price for everything. Including wind. Including solar.
52% of UK electricity. Costs 4p/kWh.
All generators sell into one pool. The priciest one sets the price for all.
Gas is the most expensive. Its price becomes everyone's. 85% of hours.
The 20p gap goes to shareholders. Every hour. Every day.
"The most expensive type of energy sets the price for all types of energy, including renewables."
— House of Commons Library, 2025In 2024, the government's REMA review considered reform — and concluded it was "not deliverable." The lobbying worked.
Legacy wind farms on old contracts get paid the gas price for electricity that costs a fraction to produce. They have no incentive to campaign for change.
27 UK energy firms. Two years. £40 billion profit. Your bills are still 35% above pre-crisis levels.
The government's own target allows 5% gas. Under marginal pricing, that 5% sets the price for everything else. The greener we get, the bigger the gap. This problem gets worse, not better.

When wind powers your home, you pay wind rates. Not gas rates. Greenpeace models £5.2 billion per year in savings. Spain is already doing it.
The current levy raised £2.6bn against a £5bn forecast. Loopholes everywhere. 27 firms took £40bn profit. Close the gaps. Return it to bills.
You can't see the gap between what electricity costs to generate and what you're charged. Make every bill show it.
Bills fall as renewables rise. £5.2bn/year national saving. Spain decoupled gas from electricity pricing — it's working.
95% clean power, 100% gas-priced. The gap keeps growing. Energy companies extract more every year.
Every statistic is verifiable. Where figures are modelled, we say so.

gov.ukI'm James, a creative director from London. I'm not an energy policy expert. I'm not affiliated with any political party or campaign group. I'm just someone who looked at his electricity bill, looked at the news about record renewable generation, and couldn't understand why the two numbers didn't match.
So I did the research. I found the mechanism — marginal pricing — and I found that it's been known about, written about, and lobbied over for years. The government reviewed it and chose not to act. The energy companies profit from it on both sides. And nobody had put the whole story in one place, in plain language, with a way to do something about it.
This site is that attempt. Every statistic is sourced. The calculator is illustrative but based on real data. The email goes to your actual MP. If you think this matters, share it. If you think I've got something wrong, tell me. This isn't a finished campaign — it's a starting point.
