Some other suggestions:

The University of Auckland (Eamonn O'Brien and Marston Conder)

The University of Warwick (Derek Holt)

I did my MSc with Eamonn O'Brien and my PhD with Derek Holt, and can recommend them both as supervisors. You are welcome to contact me by email (which you can find on my website) if you have any specific questions about either university.
