How to apply for Superheat Tariff



Guernsey Electricity reserves the right to interrupt a supply to dedicated heating tariff meters, in the unlikely event of severe network conditions, for up to 30 minutes in a 24-hour period with the maximum number of interruptions being four times per calendar year.

Subject to final approvals by CICRA, the Superheat Tariff will increase from 8.43p to 9.00p per unit from 1st July 2019. This tariff increase is in order to recover historic, uncontrollable increased costs related to the importation of electricity and on-island generation. This increase is temporary and will be in place for a period of three years.
