OFGEM has advised that, in England, Wales and Scotland, if an electricity supply is cut off as a result of severe weather conditions, the usual electricity guaranteed standards do not apply. How much you can claim as a goodwill gesture depends on the severity of the weather conditions. The severity of weather is measured by the number or percentage of households affected:
Category 1: £25 if the supply is not re-connected within 24 hours, plus £25 for every further twelve hours until it is re-connected, up to a maximum of £200
Category 2: £25 if the supply is not re-connected within 48 hours, plus £25 for every further twelve hours until it is re-connected, up to a maximum of £200
Category 3: £25 if the supply is not re-connected within x* hours, plus £25 for every further twelve hours until it is re-connected, up to a maximum of £200.
*x hours is calculated by a formula, which includes the number of people affected as a percentage of the number of customers of the electricity distributor.
If you have waited for more than 24 hours to have your electricity supply re-connected should, in the first instance, contact their electricity supplier.
In N. Ireland, Northern Ireland Electricity will reimburse a domestic customer £50 for more than 24 hours without electricity, plus £25 for every 12 hours after this. There is no maximum amount.
