Need £21 ASAP for electric fee as the emergency as run out, have small child

Hey comrades, me and my partner and kids just run out of electric, we were already using the emergency so the meter key needs to be top up with £21 as soon as we can, this is completely my fault I though it'd last till the 14th

I can accept uk bank transfer if anyone can help me out? maybe can set up another method if that all people can do, can provided identity, proof of stich and so on, thanks comrades
