changing address using power of attorney

I have power of attorney in financial affairs for my mother, who has moved from her flat into a dementia care home. The LPA was registered in 2010 before everything went online, and she does not have a government gateway account, nor any of the necessary verifications. I just want to update her address and also get any correspondence sent to me, as she does not have the mental capacity to make decisions. I have a certified copy of the LPA that I can send to the BX9 1AS account, but what other documents would I need to include? Would flat sale and care home invoices, plus proof of my identity and address be enough?

Hi

The certified copy of your LPA, along with a covering letter confirming your request and your mother's new address, should be enough to update her record. 

Thank you

Do you accept copies of an LPA certified by the Post Office?
