With the part time jobs, things might work out with Brexit. I’m not following politics but I’d imagine they’d be fewer workers from other countries. And I know that when I put adverts out on Gumtree in the past, I’d get hundreds of applications so I’d take that with a pinch of salt.
Feel free to take it with a pinch of salt, but it's direct experience, not scaremongering.
I'm a London based student & working mother with working(now not) student DC, having to budget to support their and my study.
It isn't normal here to have hundreds of applicants for real actual jobs. Commission based sales 'opportunities', chuggers MLM's maybe, but actual jobs, no. 15 to 25 applications for a good pub job with approx half having previous experience would be normal times.
Entry level jobs are going to the recently redundant highly experienced & overqualified, taking anything for fear of being left unemployed, causing a major knock on effect. Deliveroo riders etc unable to earn in over saturated markets.
I'll be very happy to be wrong, but we've all worked prior to and through uni, with no difficulties securing work before now.
I really would budget with an assumption of not easily getting work at the moment, and then it'll be a nice bonus if things change or they get lucky.
Brexit is very unlikely to cause many immediate London job vacancies, if at all, however women (predominantly) having to give up their jobs as unable to get childcare when schools reopen with sporadic hours and WFH ceases, may. No one's sure how much that will be offset by further job losses expected when furlough ends in October.
Halls and similar uni accommodation in London are an overpriced luxury. Between £75 to £125 is average room price for sharers and lodgers.
Crime; generally not a big issue unless foolish, but street robbery/ burglary/ bike thefts can rise around unis in Sept. Usual issues for young women. Exception is around drugs; students can underestimate how vicious and organised the circle that 'cool dude who delivers' is part off.
London traffic, and hire bikes, should be treated with caution.
