As far as jobs go my best advice would be to register with monster.co.
uk and post your resume up there even if you put your Canadian contact info on the resume you will be surprised how many recruiters will contact you.
I moved back to the
UK on the 30th September this year after 8 years in Toronto - about 2 weeks before coming did the monster.co.
uk route and had 2 interviews lined up within a couple of weeks of getting back I was back in work by the 10th November.
The Job market in the service sector is slowing up over here - However the IT sector seems to be okay.
Living arrangements should be too hard - do you have family over here you could stay with? If not it might be wise to rent a room for a few months to get settled before looking for an apartment.
Getting a bank account is not hard - I bank with HSBC in Canada and now in the
UK I
transfer money from the
UK back to Canada once a month costs £9 and happens same day - don't know why some people wait 4-5 days to
transfer money.
You will not get a debit card (Interac Card) or credit card over here straight away so I would hold on to those Canadian cards.
As to how much money I would aim for at least £1000 - £2000 for each month and anticipate you could be without work for at least 2\3 months.
