Renewables definitely help and I think the UK is doing quite well there but it's a little disingenuous to not even mention the price cap that the government has imposed!

What's the price cap got to do with it? You can get tariffs that are very cheap and outside of the price cap: https://www.goodenergy.co.uk/wp-content/uploads/2025/11/Good...
The price applies to default tariff so it is a price that is always available to customers. This means other non-default tariffs like the one you linked have to compete with the flat rate of 26p/kWh.
The tariff you linked is much more expensive than the price cap for most people because most people don't have huge batteries for energy storage. Battery energy storage is worth money so essentially you are getting cheaper energy by selling that storage value to Good Energy. Overall the total value you get from Good Energy (taking into account the value of having storage) is going to be about the same as the value with the price cap and no storage.
Because the tariffs are competing, if all energy retailers were able to raise their prices to their true cost, then it would be all tariffs that increase in price; not just the ones that the cap applies to.
This is similar to why electricity prices went up when there was a gas shortage due to the Ukraine war. Everyone was like "but it's a gas shortage not an electricity shortage!". But of course electricity and gas are in competition in many cases (e.g. for heating), so their prices are linked by shared demand.
If you still aren't convinced, imagine the energy price cap was 1p/kWh. What do you think would happen to the price of EV tariffs then? (For a few weeks until the entire energy retail sector collapsed anyway!)
