No, distance from exchange doesn't really have much effect. Speed of electricity in copper is almost the speed of light, so 1.58km would still be covered in way less than 1 millisecond.
Given you're in Glasgow and have 16ms interleaving, your minimum latency looks about right. Your minimum latency is comprised of:
Inherent latency of ADSL itself - approx 8-10ms
Additional latency of interleaving - 16ms
Distance to London - usually around 9-12ms depending on ISP.
The first and third cannot really be changed - without switching ISP - but on the other hand interleaving makes up almost half your total latency and that can be changed, if you complain enough to Sky, apparently.
Do you happen to know if FTTC is coming to your area? If so, that reduces line latency to about 4ms, and usually comes with no interleaving, leaving you with a total latency of around 16-20ms.
