Hey, I did a PhD in the University of Liverpool some 12 years ago. I had a scolarship from my home country, but had a blast in my 3.6 years in the UK.
I remember seeing colleagues from the UK who got a good stipend. I think in general in the UK doing a PHD was good at that time, specially because it usually lasts only 3 years.
Nevertheless, after spending other 4 years in academia, I turned to Industry and would never go back. Academia is broken at this point in time.
Where in the UK? What field? There are several important details you are leaving out.
