Simon Harding at Aberdeen Bike School. He took my son and me through CBT, Module 1 and Module 2. Very good instructor and can work the training around your availability.
I did my DA with Eric at BikeTec many years ago, cracking instructer and great banter.
More recently quite a few of my friends got their license via Simon Harding as mentioned above - he's also one of my group of biking mates so will vouch for him too.
