My flat’s ownership documents currently list my uncle’s name first and my mother’s name second. How can I change this so my mother’s name comes first, followed by mine? What are the steps involved?

You can change the order of names in the ownership documents through a deed of transfer, where your uncle transfers his share to your mother and then your mother transfers a portion to you. This requires the consent of all parties involved and involves legal fees, stamp duty, and registration with the relevant authorities.
