Currently in most parts of the country, council tax is a much bigger burden. On a £200 per month flat in the valleys council tax would be over £800 per year so approx another third.
Handsoff - if I could rent a flat in London for £200 per month I would gladly pay only £800 per year in council tax. The average rent round here for a 1 bed flat is £900 per month with council tax of £1,400 per annum. By your reasoning it should increase to £3,600.
So you pay £200 x 12 plus £800; total £3,200 per annum
I pay £900 x 12 plus £3,600; total £14,400 per annum
And you think you have the bigger burden?
As for your Westminster statistic, which is totally unrepresentative of what the majority of Londoners pay, how about his one instead.
Minimum wage for over 21s is £6.50 per hour.
Rent at £200 per month = 30 hours per month
Rent at £900 per month = 138 hours per month
or
Rent at £200 per month/138 hours per month = £1.50 per hour
Rent at £900 per mont/30 hours per month = £30 per hour
Gotta love statistics.
