Did you know there is such a thing as Disablement Relief which is administered by the Council Tax Dept. If you meet the criteria, which my husband does, you can have your council tax banding dropped to the next lower band. Ours has been dropped from D to C, saving us approx. £250.00 per annum.
I understand this is paid for by the Govt, not the local authority, and very few are aware of it.
