This is a free step-by-step guide to a potential council tax cashback windfall, possibly backdated to when the system started in 1993.  Already hundreds of MoneySavers have tried and succeeded in getting £1,000s, and thousands more are in the process.

In a nutshell, council tax bills depend on your home's band, allocated based on the property's 1991 value. Yet no one came to your home to value it; it was usually done by “second gear valuation”, meaning estate agent would drive past and estimate the band. Staggeringly, in England and Scotland it hasn’t been revalued since; leaving more holes than in Swiss cheese. Check your council tax banding, if it's wrong challenge it and you may be repaid thousands.
