Business rates, and the bill most people never question
Business rates are the third biggest fixed cost for a lot of Greater Manchester businesses after wages and rent, and they are the one nobody looks at twice. The bill arrives, it goes on the direct debit, and it stays there until the next revaluation.
The arithmetic is simple enough to check yourself. Your rateable value is multiplied by a national multiplier — 0.432 where the rateable value is £51,000 or less, 0.48 above it. Then Small Business Rates Relief comes off: 100% relief below a £12,000 rateable value, tapering to nothing at £15,000. A small unit at £11,000 pays nothing at all, and a great many businesses that qualify have simply never claimed it.
Above £15,000 there is no small business relief, and this is where the number worth challenging is the rateable value itself. It is set by the Valuation Office Agency, and it can be wrong: the property has been altered, the floor area is overstated, something outside has changed. The Check, Challenge, Appeal process exists precisely for that, and the saving repeats every year until the next revaluation.
Use the estimate at the top of this page for where you stand, or the full business rates calculator if you want to compare properties or regions. Neither replaces looking at the valuation itself, which is the part that is genuinely worth an hour.
