Close Sub Prime Card?

GavL

Hoping for some advise as toying with what to do.
Vanquis card taken out a few years ago as a 'credit builder' card - £3500 limit and no balance. As credit improved, my eligibility for 'high street' cards got better.
As well as Vanquis, I now have a Barclaycard Platimum with no balance and £1200 limit, and an M&S credit card with £5500 limit and £900 balance (interest free, was a BT offer).
I know that having available credit and not using is good for credit file, but is the sub prime element of the card a factor? Should I cancel Vanquis? I currently have it set up on pay in full DD for small monthly purchasing. Same as Barclaycard.
TIA

If you only have the three, keep it.

Lenders don't care about who you hold a card with (ie. sub-prime or not) only the limits and how well you manage the accounts. Personally, I'd keep it open and keep using it as you (presumably) have been to make a few small monthly purchases and pay it off in full.

Yes, just the 3. Great, thanks. I don't intend to apply for anything anytime soon, I just wasn't sure if it was a factor as and when I do.
