Pay in full or 0% interest payment plan?

[SnarkyBag]

I’m about to have a lot of dental work done to the tune of £3-£4K. I do have enough money in savings (well combination of premium bonds and was considering doing a stocks and shares ISA). If I paid in full I’d still have savings but am wondering if paying interest free would be better and keeping the savings?
I don’t have any other debts at all apart from a mortgage and generally always pay outright when I have the money saved. But for some reason this feels like a lot to pay one go (maybe because it’s essentially cosmetic so I’m struggling to be comfortable spending so much on just me!)
Is it ever really beneficial to do a payment plan or should you always pay in full if you can?

Invisalign?

I split the payments out - as also if you haven’t paid all upfront you have something left back to discuss if it doesn’t quite go as you like

I'd happily take out 0% finance if I could afford the payment in order to preserve the savings. It makes no difference really and if for whatever reason you want to end the finance you can pay off presumably?

Take the 0% finance. It will improve your credit rating if you make all the payments on time (and why wouldn’t you if you have the cash already).

Plus I would tried to pay from my day to day money if I could so then would keep the savings. Which I’m more likely to do to pay debt than to resave the money. Just how mu mind works!

Thanks. All very good points especially having something to discuss payment wise if I’m not happy with the way it’s going hadn’t thought about that at all.

Who is the finance with though? does that make a difference. .I brought a camera once through jessops but the finance was with klarna. ...I had no problems but I wonder what the situation woukd have been if the camera had been faulty. ...ie still paying back klarna but taking the issue up with jessops?

What I am trying to say is make sure you understand the nature of the finance!

@popcornpopping it's no different to if you'd spent the money up front. The contract is with Jessops if the camera is faulty, you have to resolve with them in just the same way you would if you had paid and lost the money in one go, you don't just stop paying Klarna because the camera is faulty, that's nothing to do with them. It's the same with car finance, it's two separate contracts.

@namechange90832 thank you. yes so if op is unhappy with the ongoing dental work they cannot withhold payment because finance contract is with a different party?

@popcornpopping, if it's a separate companies as you describe absolutely not, if they are offering the finance directly there may be slightly more power for the OP, but unlikely, any holding back of payment will likely be classed as a default.

I always use 0% interest when available despite having the savings for it. I think that makes sense.

As long as u aren't planning on applying for a mortgage soon, I would do the interest free. Then pay it up. Then the money stays in ur name for longer, making u interest etc..
