Most people’s unit rates tripled at the height of the energy crisis, although they’re gradually coming down a bit. Gas is still high; I was paying just under 2p per kWh for gas just before the crisis began, now most households are paying around 6p. For electricity, most are paying around double what they paid three years ago.
As I mentioned above, smart meters are necessary if we’re to wean ourselves off our chronic dependency on gas for electricity generation.
