Andrew, how does a Voltage Detector Stick work in determining off peak (and/or peak) times? Searched the web however nothing specific to the use you mention. Would appreciate yours and anyone else’s input.
Otherwise, am currently on the hunt for a good economy 10 rate (have an economy 10 meter), currently on economy 7 Move in Saver 2 Direct Debit with Spark Energy. Their prices are going up in November 2017 so it is moving to their Simple Saver March 2019 Fixed tariff if I can’t get a good economy 10 deal.
