Consumer champion Martin Lewis has backed calls for energy back-billing to be limited to six months as he singled out Scottish Power for being “particularly abominable” at the practice.
Appearing in front of the Energy Security and Net Zero Committee, Mr Lewis said the “principles” of back-billing were “certainly clear” – that firms should not back-bill customers for energy used more than 12 months ago as long as there has not been an unreasonable obstacle.
