What do I need to Work Part Time?

Hi there, I am a Canadian Student and will be going to London, England for 3 months this summer. I am thinking about working part-time while I am there but have been unable to find out what I need (if anything at all) to do so. If you could let me know I would GREATLY appreciate it! Thank you.

Try looking here: http://www.bia.homeoffice.gov.uk/studyingintheuk/ It has details on studying in the UK. To work, you will need to get a separate permit from the Study permit it looks like. Here is a link to various types of permits - not knowing a lot about your situation, I'm not sure which would/would not apply to you: http://www.bia.homeoffice.gov.uk/workingintheuk/
