No, far from it. You might get lucky but better to replace as a set.

No.

A complete toilet can be had for £49 - just what does he think he will be saving by getting the pan only?

I am encountering this issue as well. I require to replace the pan (bowl) and would rather not replace a perfectly working cistern.

To be clear; even if I am required to buy a complete set (pan and cistern), I would still want to just replace the pan.

The answer to @flameport question is it would be less hassle to leave the cistern as the water inlet pipe is rigid. It would be a job to refit/adjust the inlet pipe to a different cistern.

Has anyone ever just replaced the pan?

The crucial compatibility issues are;

1) the replacement pan must be the same height as the worn one.
2) the soil outlet must be the same height and horizontal distance as worn pan.
3) The diameter of the interface hole between the cistern and the new pan must be same.

Would this be correct?

You should have started your own thread. I can't picture a scenario where you're going to be saving a significant amount of time or hassle by not replacing the cistern. Your cistern will need to be disconnected from the pipework to decouple it from the pan anyway, at that point you can cut the pipe back where you want it and install a flexi without having to bend any copper or cobble together fittings.

If the toilet is couple coupled, you will need to replace the whole lot unless you can get the same model. If the toilet is low level or back to wall with a concealed cistern, you can easily replace just the pan.
Might need a new flush pipe and you should definitely use a new pan connector and flush cone.
