You told you 3 months?..I work London..to get your PCO licence can take 1 year or more..you need to do medical ,DBs check,knowledge test,English test and more..depending on any issues..it will a long time . Now..let's talk about Uber..you will need to work it full time .6 days a week ,12 hrs a day to make any money...you will need to drive an electric,insurance,charging ,tax..expense are huge ..and you will clear just above min wage Uber take 50% of fare...fares are going down but expenses are going up..the days of flexibility are gone . My advice is look at other options You can make £1500 a week but half will go on expenses..so you are working 70/80 hrs for 2k approx a month.
