is it a big no no to connect a heated towel rail to the lighting

Perfectly ok. Unlike ring main circuits, lighting ones are protected at
their maximum continuous rating under any conditions.

But it would be worth checking to see whether the lighting circuit is
RCD protected would it not?

And even better to check whether it has a CPC?!
