Ask HN: Dev bootcamps in the UK

I'm looking to move out of my current PR/marketing career into development. I've got basic programming experience, and I'm having a lot of fun with self-directed learning, but I think something more intensive is going to be needed for me to progress to the next level and get a junior dev job.

It looks like App Academy [appacademy.io] is setting the bar for coding bootcamps in the US. The program is free at the point of use, with costs being recouped from your first year's salary.

I'm looking for something similar in the UK, particularly in London.

What's everyone's experience with these types of bootcamps?
