You can't afford 220 pounds for a PC - try gumtree, you can get an internet capable one for about 30 pounds. If all he wants to do is job search and write CV's, it'll do the job and more.
You honestly can't expect to be given something. I've been on the dole before, and it's grim, but I managed on what was essentially a hand out.
I looked into broadband recently for my new house, and no mention on ANY advert had line rental included in the price - you don't pay the broadband provider the line rental, you pay the line operator (ie BT). It is assumed you have a phone line already, and you pay rental on that. I plan on moving soon, so I didn't want a 12 month contract - and running contracts cost a lot more, so I stuck with using my IPhone as a wireless modem as I'm paying £30 a month for that anyway.
Try getting a wireless dongle and buy credit for it. I found I didn't even use £10 worth in a month, and that was downloading as well.
