The two price columns can name different providers: the lowest first bill does not necessarily produce the lowest minimum-term cost. Equal prices are resolved by the other cost measure, then dataset order; a displayed winner may be tied. The term shown is for the effective-cost winner.

How often are price rises disclosed?

These counts describe individual standard tariffs, not a customer-weighted market share or a test of provider reliability. The assumed start date matters: an annual rise can fall outside a shorter minimum term.
