This is roughly what we have in the UK.

For electricity, the standing charge is 61.6p/day, then 23.3p/kWh.
And gas is 29.6p/day, then 6.1p/kWh. (The numbers vary, and you can choose to lock rates for the duration of a contract).

There has been some discussion of it in recent years (after it doubled, thanks Putin).
Whether it is fair for people using less energy…But in reality, everyone has similar 100 or 60A connections to the grid.
There are tarrifs for very low users, where the standing charge is combined with the first kWh.

Once I’m off the gas boiler, and on a heat pump, I may get my gas disconnected to save the standing charge.

On a tangent, as you may be interested, we now have the option of flexible electricity pricing that tracks the wholesale rates for the day. Usually, it’s cheaper, sometimes even negative. Link.
However, this week there has been a lot of expensive energy, so it’s been butting up against the £1/kWh limit!
