Meaningless Direct Debit References

Hi, I have multiple accounts with bulb and each associated Direct Debit has a unique, fixed reference that is shown on my bank statements (eg D.DR BULB ENERGY REF 2DDGR38-BULB, often for the same amount taken on the same day. Unfortunately these references do not appear on my Bulb statements or Bulb online accounts so how am I supposed to be able to tell which payment relates to which account for accountancy purposes? Thanks

If you have separate Bulb accounts, presumably that means separate energy statements which will show the direct debit payments for each specific account. Just cross-check the amounts with your bank statements?
