I would thoroughly recommend Kingsmead. We had our loft conversion done over Christmas 2014 - which on the face of it looked like a silly idea. However, the team were able to get the structure all set up before Christmas and finished the job shortly after Christmas. We were made aware at each stage what was going to happen and were impressed by the team employed to do the job. Decisions needed to be made along the way and we never felt pressurised - just given the options from which we made our choices. The room is fantastic and 6 months later we can't remember what it was like before the conversion! We retained a decent amount of storage and the natural light that we get is fantastic.
