Proof of rental expense - working from home

Hi, I worked from home about 20 hours per week from 2020-2022 in a house share. I paid one weekly sum with all bills included. I can't seem to find any specific information on what records I should keep to prove my rental expenses. Are bank statements sufficient, or what evidence should I keep for this? Thanks.
