We have the highest electricity costs in Europe but only 3rd highest in gas costs. Yay for us.
I think that's right based on the price p/kWh, but is a recent change and once the price cap comes into play, that average unit price falls for most.
It's all relative though and there are a lot of other factors to consider when comparing nation to nation. We have relatively high average earnings here. Our minimum wage is now one of the highest in the world, only about 6 nations have a higher rate and only Switzerland and Luxembourg in Europe.
Our tax system is generally more progressive - we have a 12K personal tax allowance - no other major European nation allows you to earn that much without paying tax on it. We have things like tax credits and other in work benefits that simply don't exist in other European countries, as well as a fairly generous benefits system overall - although not perfect. Our state pension is pretty woeful though.
Point being is that it is hurting everywhere, but how much it is hurting low income families is down to much more that just the unit price of energy.
