What Is Time Limit?

[lynbrown]

We have had a bill from our factoring agent passing on an outstanding electricity charge covering Feb 2019 to May 2020, ie 15 months. I have a feeling legislation was passed recently saying you could only be charged for outstanding bills of up to 12 months only. Am I right?

The Ofgem rule only applies to 'household and microbusiness energy customers', so if you're running a business (other than a 'micro' one, whatever that might be) it won't apply to you.

However, if the rule does apply to you, you can find a relevant link (to Citizens Advice, for a draft letter to send to the energy company) on the Ofgem website:

It depends whether they have asked for the money before. If bills had been issued but ignored then I don't think that counts
