A lower band isn't only a smaller bill from now on — it usually comes with money back for the years you overpaid. If your band was too high, you were charged too much, and that overpayment gets refunded. Here's how far back it goes and who actually pays you.
A refund is generally backdated to when the error began, or to when you became liable for the property — whichever is later. Council tax started in 1993, and many bands have been wrong since then, so a long-standing error can mean several years of refund. The exact period depends on your case and how long you've been the taxpayer there.
Why it can be a big number: one band too high isn't a few pounds — it's a chunk of every bill, multiplied by every year you've lived there. That's what makes correcting a 1991 mistake worth the effort.
It's a two-part process, and knowing who does what saves confusion:
So the refund arrives from your council, usually after the VOA has updated the list.
