UK Inflation and rising household bills

[MintChocCat]

I’ve just read the following article - UK inflation jumps higher than expected to 3.5% amid bills increase and I was wondering why governments don’t do more to regulate or cap the costs of household bills, specifically companies like oil, gas and electricity? Surely it would be fairly straightforward to do this, or am I being really naive here?

Living in the UK in my mid-30s is just becoming really challenging and increasingly difficult financially, and we don’t yet have children. I’m worried financially for the future.

I know we have Ofgem but they keep rising the energy cap year on year, so what exactly is the point?

How much are they allowed to do? A lot of Americans are complaining, but they seem to forget that in a capitalist society, government isn't normally supposed to fix prices.
