Get insurance for your mobile phone to start the minute you leave home – you will lose or smash your phone at least once. Contents insurance for your belongings while living in halls and in private accommodation later is also a good idea, but make sure your laptop and any other high value items are included. Always lock bikes and store them inside the house if possible
Buy or renew a student railcard – this will save you pounds on train travel especially if booking in advance. Cheapest way to travel is usually the Megabus but journeys can be longer. National Express coaches are worth checking out too
