UK prices, checked 22 August 2026

What things actually cost, per wash, per cup, per mile.

Everything here is worked out from the same four line sum, priced at the current cap, with the arithmetic shown. No round numbers borrowed from somebody else's article, and no figure without the date it was last checked.

Six comparisons worth knowing

These are the rows where the gap is large enough to change what you would buy. Running cost is what it takes to use the thing. Cost per use adds what you paid for it, divided across a realistic lifetime.
