I learned to fly in Inverness, and was extremely happy with my training there. It took me around 2 months spread from November to January, and there were only a few days that were completely unflyable in the local area, though several weeks of that time were spent waiting for good weather for my qualifying XC. I could also have sped things up by getting my medical in advance.
Since moving to London then Wales, I've come to appreciate the learning environment at Inverness even more. There are several runways which means that you have good facilities for practicing crosswind landings. It's a controlled airport so you get good practice on the radio, as well as being close to grass strips. There are MATZs close by, so you do lots of MATZ crossings. The landscape is stupendous, and the qualifying cross-country is generally to Wick and Kirkwall.
I found the flying school friendly and well set up. Prices at the time were very competitive, especially as the landing fees were included.
