How UK Council Tax Bands Work

A council tax bill landed at your new place and the band letter means nothing to you. This explains what the A-to-H banding is based on, who sets it, how the bill is calculated from the band, and which discounts and exemptions you might be missing. Plain answers to a bill that explains nothing.
