Charging in the UK is straight forward, we use 240 volt domestic supply and 3 pin plugs (earthed). If you're using two pin, you can pick up a shaving adaptor plug pretty much anywhere.
If you're taking a laptop or will have access to a USB port on a PC, you can use a synch/charge cable from PDairShop or an incar charging kit from someone like Belkin.
Enjoy Scotland, it is a beautiful place, one that I am fortunate to visit often on business.
