A fixed-rate tariff is a pricing plan that keeps electricity or gas charges stable for a set period, such as 12 months. It gives customers predictable bills and helps providers package an offer around certainty rather than market volatility.
In cyber security, fixed-rate tariffs matter because they are usually managed through online portals, sign-up forms, and switch workflows. Those digital paths must protect contract data, payment details, and customer identity. Attackers may try to impersonate a supplier, alter billing information, or exploit weak verification to push unauthorized changes. Good defenses include strong authentication, clear confirmation steps for switches, tamper-resistant records, and secure customer communication so the stated tariff matches the real contract.
