If your car came with a 15" full sized steel spare wheel, and your car now has 16" alloys on it, then that 15" original spare wheel is still okay for that car.
Put it this way, my wife has a 2015 VW Polo 1.2TSI SEL bought new, that car came with 16" alloys as standard and a 15" steel spare wheel.
Edit:- the bigger 16" steel spare wheel is only needed when the car has bigger front brakes, like 314mm, if it has 288mm or 256mm front brakes, 15" steel wheels fit over them easily - as you must know if your car came to you with 15" wheels.

Wouldn't that cause issues seeing as the spare will be smaller than the rest?

The tyre on the 15” space saver will have higher profile sidewalls than the tyres you’ll be fitting on your new alloys (presumably 215/45 R16 tyres), so the overall rolling radius of your existing space saver compared to your new wheel and tyre combination should be pretty much the same.
As RUM4MO has said, as your existing space saver fits over your brake calipers, then there’s no need to get a larger space saver spare.

Ok, it's a full size spare 15"
Still the same thing though?

Sorry, I missed that you’d said the spare was a full sized wheel and not a space saver. I’d agree with RUM4MO that the 15” wheel with (presumably) a 185/60 R15 tyre should be OK to use as a spare on a car with 16” wheels and 215/45 R16 tyres. You could only use it as a spare on the car as a temporary measure though to get you home or to a tyre place. I think the same speed restrictions that apply when using a space saver spare on a car might also apply (50 mph max) as your 15” tyre will be a different width and may have a different speed rating to the other three tyres, so the handling characteristics of the car might be different and unpredictable under certain driving conditions.
As said regardless of the rim diameter of a spare wheel and even if it has the same tyre size on as the other wheels on a car, it will always be classed as a temporary spare wheel and so limited to a low maximum speed limit, although these normal road tyres will last a lot more miles than the skinny space savers.
Only one useful reason for changing your 15" steel spare wheel to a 16" with same sized tyres as your new 16" alloys is, as time goes on, when it is time to replace a tyre, I have in the past while being in this situation, swopped the best used tyre onto the steel spare - and when I had an severe puncture early in that car's life, I swopped the unused spare tyre onto the car and got the next tyre fitted to the spare - by that time, time had moved on and I could not buy a new "same" version of the tyres fitted to that car.
Okay if you plan to increase the brake calliper/disc sizes, then moving up a wheel size might be necessary, otherwise, not really needed.

Was only able to get this picture before losing the light but absolutely buzzing with the new alloys!!
And so you should be! They look great on your car. . Good to see you’ve got some good protection on them and some decent tyres too.
Thanks! Will get more pics tomorrow after work.
Made sense to deep clean and ceramic coat then whilst they were off the car.
And yes, Continental tyres. I never cheap out on things like that
hopefully arrive all good and then slap some tyres on and they'll be right on the car
