Options upon failing first year?

Long story short, very likely ive failed my first year of architecture at London Metropolitan due to lacking commitment and leaving everything till last minute, but i want to take a gap year, get my act together and reapply to another university for the same course. Does anyone know how easy this is to do and how likely it is that I will get into another university? If anyone has been in a similar position regarding failing their first year but realising that they've been a complete idiot for not giving it their all, would be really helpful to hear what u did upon leaving. Also any specific unis that anyone knows of that have accepted people who have previously failed or dropped out would be interesting. Thanks in advance for any help
