I had a student overdraft of £2000 which I've just paid off finally after an initial period of irresponsibility after getting my grad job and the past 3 months of going all in to pay it off. I feel so much better without this burden which is nice, but should I keep the overdraft on my account or should I straight up cancel it? I'm not worried about needing to go back into it but how does this affect my ability to get credit (if it does at all)?

Any help would be appreciated, also, I've got a Lloyds Graduate account right now, should I switch it to a Classic or even Club Lloyds (as I'll pay in more than the minimum to keep it free)?
