Worth noting in case this helps anyone - there are circumstances where it is legal to park for a period of time on double yellows when loading/unloading, but it does vary by borough. Southwark info is under the yellow lines section here https://www.southwark.gov.uk/parking/guide-to-parking/loading-and-unloading My advice would be - check the time limit (40 mins in Southwark), make sure you are visibly loading/unloading - have a door or boot open if possible and particularly hazard lights on, do not block anything, don?t do it where it is forbidden (look for perpendicular yellow lines on the kerb), and pop a ?loading only? note on your dashboard. Hope this helps. Edit: at your own risk of course!
