The funny thing is those who have never had a CC are more of a risk in lenders eyes.
Certainly in the UK, it is good to have credit to demonstrate to lenders you can afford, repay and use it sensibly. I upgraded from the iPhone 11 to the 14 last year for my wife and me. Took it out using the Apple 2-year interest-free. Nothing at all to do with not being able to afford to buy them outright, it's just so that it shows up on the credit report.
I do some apparently silly things from time to time, like paying for a £60 dominos delivery using Paypal's pay in 3. No interest is paid, it's just simply for it to show in the credit report.
None of the above I would do if I couldn't afford to pay in full at the time. As I don't have a mortgage anymore I wouldn't have anything on the credit report if it was not for doing the above.
My Score is below. I was at 1,000 until my mortgage was repaid, that alone cost me 62 points, just because I repaid it! A recent missed payment will cost you 100 points. Multiple missed payments across multiple accounts and you will be down at the UK average where the deals are limited and the rates are much higher.
The credit rating thing comes up a lot. But if I never intend to borrow money it’s really not a risk.
Fair enough if that's your approach, the credit rating thing is real and only a risk if you never have to borrow. If the time ever comes it is better to have played the credit rating game than let your score drop. A low score does not mean you can't borrow but it will limit your options and increase the rates you will pay. That is going to be important if you are in a position where you need to borrow in the future. Especially if it's because your financial position has changed for the worse.
My position is that a little effort now saves a lot later.
