Right under where my rad is required there sits one of the floor joists. Therefore I cant easily drop the pipes from the valves into the floor space. Whats the best way of doing this? Notch the joist so I can get an elbow in?

You can buy adapters, which allow existing old radiators, to be replaced with modern ones a little less wide. One of those would move where the pipe needs to rise vertically up from the floor.
Do you know what they are called?
Radiator Valve Extension https://www.toolstation.com/radiator-valve-extension/p37352
They come is different lengths.

The way I understand your problem, is that the radiator pipe as it goes into the floor, will hit a joist. Is that correct?
You can extend or move the radiator valve horizontally, with one of those extensions, so it misses the joist.

I’m not sure that would work, as the joist is running horizontally, so it would still hit the joist.
@WabbitPoo, could you offset the pipe?
Options are limited. Neatest is use a pipe bender to put a jog in the tube. With 15mm you can do it with a bending spring over your knee but be prepared to waste a few sections getting it right.
Shoddy is have the pipe dropping at an angle, but it'll look rubbish.
Fairly shoddy is 2 45 degree elbows forming the jog.

Now I have grasped the problem, what is at the back of the wall behind the radiator - could you go through the wall then down?
SDS = easy.
A couple of 90° elbows and notch into the joist?
We're making a meal of this. Notch the joist and use a 90 elbow.
Pulled bend wont give you the tight radius you need.
