National Grid's free Priority Service Register provides extra support during a power disruption for the elderly, very ill, disabled or those that rely on power for medical equipment. National Grid will provide you with a dedicated and direct number you can call during power disruption. Being on the PSR also enables them to keep you up-to-date on any planned disruptions to your power supply. National Grid will also stay in touch with you during an unplanned power cut, including advice on how long it will last. Through partner organisations, access for customers on the PSR can also access numerous additional services ranging from advice to emergency fuel vouchers.
