Some misconceptions are being put out here. You don't always need a degree in the subject you're teaching, many if not all places (especially a SKITT rather than uni) will test your knowledge in the subject. They're looking for adequate rather than proficient, as much of it can be learned as you go.
It is also not absolutely necessary to have experience beforehand, but it does help. Something like a cover supervisor or TA/HLTA would be best, as you get some real experience in both behaviour management and lesson structures. Showing you have good experience in both these areas will be a big positive. Showing knowledge in safeguarding and SEN also works in your favour, as it's a huge part of teaching regardless of your subject.
Otherwise it's down to you personally. Teaching is very intense, are you able to be at work from around 7.30-8am, stay until past 5pm (much later if there's training or parents evening) and then look to be doing marking or lesson planning well into the night/on weekends? It wouldn't just be your own lessons either, you may be asked to cover another subject.
The money side is also not great. Very few subjects now actually 'pay to train'. You may only be looking at a small bursary in history or English. The former in particular is over subscribed as a subject. Pay scale isn't great over the years if you have no want to climb too far up the ladder, and if you do it's even more training.
Despite all this, and the huge issues in teaching, there are many who find their way in it and end up not doing too badly. Having a teaching qualification isn't a bad thing on your CV either.
