@Kerry87 So sorry this is the worst time, customer services are not back till Monday morning. Check the help pages to see if you can get emergency credit. Google PAYG emergency credit
I gogled this for you and it took me to SP errorcode page. On call help code it states a general meter fault has occured on the gas one. You have to phone for an engineer to come out.But i don't think customer service is open on a weekend. So sorry.
You will still be able to chat to via website or using the ScottishPower app outside these times as our chat teams will continue to be available until 10.00pm Monday to Friday and 6.00pm on a Saturday
