The main difference is peace of mind about your energy prices.
A 12-month One Utility Bill contract includes a fixed energy tariff, which means that your prices won't change every three months with the energy price cap.
A Rolling-term One Utility Bill contract includes a variable energy tariff, so we'll get in touch every three months to let you know how the energy price cap will affect your monthly payment.
