I'm a diagnostic radiographer and I honestly can't think of another job I'd rather do.
Training is tough especially with placements but you will 100% have a job when you qualify, in your field which is hard to say for a lot of the people I went to uni with who studied other degrees.
Work wise you will be expected to do shifts, overtime will most likely always be available as there is a shortage but using the shortage to your advantage- progression has become easier and tends to happen quicker.
Lots of areas to specialise in. I've specialised now and in my area there are no night shifts or oncalls.
As others have said: no one will know what you do and call you a nurse which is annoying I remember a nursing student at uni who was disgusted to find out that we would start on the same pay band because all I do is push a button 
You have to register with the HCPC which costs just under £100 a year (paid every two years) and you'll likely want to join the society of radiographers which is around £24 a month
I think it's a different experience for everyone regarding their hospitals, we have a great rota which is rolling so I know what I'm expected to work well in advance, no problem getting annual leave and generally a happy place to work.
I didn't have to pay Tuition fees but if I did it wouldn't stop me doing it again.
Good luck on your journey
