... or do they know this already ? Moved in to new place October 2020, a doer upper, so very draughty during winter months so had to keep the heating on high to ensure small kids were kept warm. Moved out of the house in Feb for 6 months whilst builders were in renovating. Forgot about electricity bill during this time as lots going on with temporary accommodation and building site on top of work, kids etc. AVRO then went bust and my account was moved over to Octopus. Looking at my Octopus account now, it states that I owe then £ 250 for September 2021 until now. The grand I owe Avro is listed in historical bills but not in the main account as what I owe them, which Ive now paid in full so account at £0 at the moment. Do I now just wait and hope they have forgotten the historical bill or will they get in touch ?
