The Longer Fix v37 is a 24 month fixed tariff released on 16 December 2025. It is due to end around 30 June 2027. This tariff is not currently available for new switches. This type of tariff is usually aimed at customers who want price certainty for a set period, so the main things to review are the tariff end date, any exit fees, and what happens when the fixed term finishes.
