What is Price rise rule?

A price rise rule is the provider's own statement of what it may add to your bill while you are still inside your contract. 019 Mobile's rule reads Fixed for life or for 3 years, then rises by ILS 10, and 4th Utility's reads price rises each March in contract by GBP 4.00. 50plus Mobiel ties its yearly increase to the CBS Consumer Price Index, listed as Annual indexation in line with CBS Consumer Price Index. By contrast, 1pBroadband rules out rises inside the contract and allows an annual rise after the minimum term with notice, while 1pMobile says any change that is not to your benefit is notified in advance and you may leave without charge.
