Should the current Council Tax system be abolished and replaced with a Proportional Property Tax based on current home values?

Council Tax is the main system used to fund local government services in Britain, based on property valuations that have not been updated since 1991. A proposed Proportional Property Tax would charge homeowners a flat percentage of their property's current value, meaning bills would fall for most households in the North and Midlands but rise significantly in London and the South East. Proponents argue the 1991 bands are fundamentally unfair, allowing wealthy elites to pay proportionately less than low-income households in cheaper areas. Opponents warn it would create massive sudden tax hikes for middle-class homeowners in the South and force many elderly people on fixed incomes out of their long-time homes.
