Hit kerb at about 15mph which has resulted in pushing my wheel back against the arch. Not sure on extent of damage, what sort of problems could I be looking at and will it be costly?

I'm not expecting a diagnosis, can clearly see the wishbone will need replacing. Just looking for like the worst possible scenario e.g. could it have caused subframe bend or steering rack issues.

Yep, both of those. Possibly also gearbox damage, maybe inner wing.

Buckled wheel, bent suspension arms, bent strut, damaged steering rack, shell bent putting the vehicle beyond economic repair. You asked for worst case.

More realistically: straightened wheel, new suspension arm and strut, bit of brute force to put suspension mounting points back where they started.

Damaged CV joints are also fairly common after a hefty impact on a front wheel.

Possible gearbox damage too...

Is that a Peugeot or Citroen? Looks like a 206 to me.

I did this over Christmas and have so far replaced wheel, tyre, bearing + hub and it still isn't right. Mine is RWD though so no problems with driveshaft or gearbox at least. Next up will probably be wishbone even though it looks straight and failing that move onto steering arms. I don't know where it will end.

A fault in the wheel, tyre, bearing or hub would not result in the wheel being pushed to the back of the wheel arch, so it's not surprising this hasn't fixed the problem. Steering arms also won't cause this, but if bent they will cause tracking problems.

The parts that could be damaged enough to cause this are wishbone (most likely), strut (should be pretty obvious if bent) and the suspension mounts on the body (or subframe if it has one).

Unfortunately, you didn't really think this through.

Wheel, tyre, bearing & hub are the least likely issues here.

The damage is to the chassis/subframe dependant on the car.

I did the same as in I hit a kerb, my wheel wasn't pushed back just destroyed wheel and tyre, steering out of line a bit and bearing was noisey when I was fitting the new wheel. I can see very little wrong with the subframe or wishbone so going to get it tracked and see what is out of alignment. Hoping some adjustment will be enough to get it steering straight.

The ABS light is also on since, so far I fitted new ring and cleaned the sensor as I had knocked a lot of rust off the dustguard (also changed now) which clumped onto the magnetic sensor. Would the steering angle sensor make the ECU thing that there is a fault or do you reckon its definitely in need of a new sensor? The sensor is in the correct position.

Putting the steering out of alignment involves bending some quite substantial bits of metal which might now be weakened as a result. Unless you're a motor engineer qualified to judge whether the bent parts are safe to reuse, I suggest you either replace every damaged part as a matter of course or get a qualified motor engineer to check it for you and tell you what repairs it needs.

I don't know whether your steering angle sensor would trip the ABS light if the steering was misaligned. The wheel speed sensor seems like a more obvious candidate to me, especially since you say the bearing was damaged, which could mean the spindle and/or sensor have been mangled. Once you have replaced the damaged parts you also need to align the sensor correctly with the ABS ring. That might involve shimming it or adjusting the clamping bolts. I'm not familiar with your car but I expect the ABS controller will have some way to tell you why the ABS light is coming on.
