I'm a 3rd year university student (age 20) in the UK, and I'm half-way through a years placement that's paying ~£1200/month which finishes in July. I'm engaged, and looking to get married after I've finished uni and I'm in a job and house. Possibly one that I own, but that'll depend on quite a few factors that I can't control right now. Either way, I'd like to have at least part of a down payment ready.
I have an ISA with HSBC that's at 1.4% with ~£7400 in it, with £100 going into it monthly as my pay comes in. I'm also putting £100/month into a separate savings account each month as I'm looking to make a large (relatively speaking) purchase in July, and the account should have ~£1000 in it by the point where I'm looking to withdraw.
After this year, I'm going to be unable to pay substantial amounts into the ISA due to not having an income, so I'll likely shift it to a higher interest one that's fixed and doesn't allow deposits.
My question is, is this a sound strategy and is there anything else I should be doing?
Sub-question: Should I consider getting a credit card to start off my credit score, but use it for small purchases and pay off each month? HSBC offers a £500 limit card catered to students that I could use to 30% and pay off straight away.
