Help to save standing order

[HousePlantMurderer]

I’m finally sorting myself out and trying to set up a standing order for my help to save account but the instructions say to put your unique 13 digit number as the reference for it and I can’t find it anywhere!
Does anyone know where on the app or website I would find it?

I just logged in on my phone, scrolled down a bit then clicked on ‘how to setup a regular payment’ - then scrolled down a bit on the next page and on there it gives their sort code and account number and your unique 13 digit number.

hope this helps but if not let me k ow I’ll try to screenshot it for you

Thank you so much, I had been going round in circles trying find an account details section and trawling through old emails 🙄
